  • the usability of mobile cranes is usually determined by their structural design.
  • Technical characteristics such as load capacity, working radius and lifting height result primarily from the structure of the respective telescopic boom.
  • the parameters of a mobile crane can sometimes be changed, for example to increase its load-bearing capacity and reduce the elastic deflection of its telescopic boom.
  • additional add-on parts are known in the form of at least one guying device, the arrangement of which, for example, can achieve a reduction in the lever arm of the telescopic boom.
  • the increase in load capacity that is possible as a result is usually the result of a combination with an additional counterweight and corresponding deflections via the guying device.
  • German Offenlegungsschrift DE 198 23 380 A1 discloses in this context a crane boom transport unit with a mobile transport device in the form of a semi-trailer for transporting a main boom separate from a mobile crane.
  • the additional add-on parts in question usually have dimensions and weights that require them to be transported separately.
  • suitable additional transport devices are necessary in order to transport them to and from their respective place of use.
  • the subsequent relocation to the telescopic boom and back again requires an additional mobile lifting device with which the respective attachment can be picked up and moved on site.
  • the transport and the implementation of such add-on parts therefore still offer room for improvement.
  • a vehicle crane system according to the preamble of claim 1 and a method for attaching and detaching a guying device to a telescopic boom of a mobile crane are already known.
  • the guying device transported on a semi-trailer is lifted by the mobile crane and thereby articulated support legs connected to the semi-trailer and the guying device are set up from a horizontal transport position into an almost vertical supporting position.
  • the support legs are supported by auxiliary legs in the erected support position and the mobile crane is detached from the guying device.
  • the telescopic boom is set up largely horizontally and parallel to the semi-trailer and at a distance from it.
  • the mobile crane then moves under the guying device and between the support legs and auxiliary legs with its telescopic boom.
  • the guying device is then picked up by the telescopic boom.
  • the guying device is attached to the telescopic boom and the support legs and auxiliary legs are released.
  • German Offenlegungsschrift shows DE 197 30 361 A1 a method for attaching and detaching a counterjib to a telescopic boom of a mobile crane.

  • the telescopic boom resting on a semi-trailer is extended via pivoting support legs a horizontal transport position in a likewise horizontal support position and then moved by the semi-trailer in the direction of the superstructure in order to be bolted there.
  • the present invention is therefore based on the object of improving the previously known devices for transporting and relocating an additional add-on part as described above for the telescopic boom of a mobile crane in such a way that they allow the transport and relocation to be carried out more economically and practicably overall. Furthermore, two methods are to be shown, which in particular simplify the conversion of such an add-on part.

  • the mobile crane system comprising a mobile crane with an attachment that can be mounted on or removed from its telescopic boom, in particular a guying device, and an attachment transport unit designed to transport the attachment and according to the invention, includes a mobile transport device designed to transport the attachment, which has at least one loading arm .
  • the loading arm is designed in such a way that its free supporting end can be coupled to the add-on part which is or is to be mounted on the transport device.
  • the loading arm is movably arranged on the transport device in such a way that the attachment coupled to its free supporting end can be moved between the transport device and the telescopic boom.
  • the transport device has a tilting device which is designed to raise and lower on one side an attachment that is received or is to be received on the transport device.
  • the advantage resulting from the invention lies primarily in the combined Design of the attachment transport unit serving the purpose of use, which, in addition to the transport device serving for the separate transport of an attachment, now also contains the suitable means for its conversion.
  • the attachment transport unit according to the invention enables the measures required for transporting and attaching such an attachment to the telescopic boom of a mobile crane, in particular a mobile crane, to be carried out extremely economically and practicably.
  • the tilting device of the attachment transport unit can have at least one support arrangement and a tilting drive.
  • the tilting drive can advantageously be a linear drive or the tilting drive can contain at least one such linear drive.
  • the advantage of a linear drive lies in its extremely compact design compared to other drives, while at the same time offering high performance.
  • the support arrangement and the tilting drive provided for coupling to a first end section of the attachment are designed to raise or lower a second end section, opposite the first end section, of the attachment coupled to the tilting drive and supported at least in regions on the support arrangement.
  • the add-on part can advantageously be supported horizontally at least partially on the support arrangement, while it can be pivoted around the support arrangement to a limited extent, for example, due to a change in length of the tilting drive.
  • the at least one loading arm can be arranged pivotably on the transport device in such a way that an attachment to be loaded or unloaded can be moved on a path or a path which contains a movement component both in a vertical direction and in a horizontal direction.
  • a guying device in particular a lateral superlift, designed add-on part, this makes it easy to move up and down on and off the transport device without requiring an additional device to be provided on site for this purpose Converting the attachment required.

  • a load arm is at least indirectly coupled to its free supporting end and at the same time at least partially or partially on the telescopic boom a vehicle crane supported attachment is movable accordingly.
  • the reason for this is the mounting of the add-on part, which takes place during this movement over two areas spaced apart from one another, namely on the at least one loading arm and the telescopic boom.
  • its end region supported on the telescopic boom can be shifted more or less parallel to the telescopic boom during the pivoting movement of the loading arm, while its opposite end region is moved on a circular path of the loading arm articulated on the transport device.
  • the configuration according to the invention provides that the attachment supported on a telescopic boom of a mobile crane and coupled to the tilting drive of the tilting device can be set in motion by a change in length of the tilting drive, which depends on the direction of the change in length of the tilting drive when it is placed or deducting the attachment in relation to the telescopic boom is used.
  • the attachment can advantageously be supported on a base box of the telescopic boom. According to this, it is possible on the one hand to set the attachment in a combined translatory and limited rotational first placement movement relative to the transport device away from the transport device, in particular towards the vehicle crane.
  • the configuration according to the invention provides that the attachment, which is placed at least in sections on the telescopic boom of the mobile crane and is coupled to the free supporting end of the at least one loading arm, is moved by a movement and/or change in length of the loading arm in one of the pivoting direction and/or direction of the change in length of the loading arm dependent and thereby the attachment or detachment of the attachment in relation to the telescopic boom serving movement can be displaced.

  • the attachment to be transported and/or repositioned with the attachment transport unit according to the invention is a guying device. It can particularly preferably be at least one lateral superlift.
  • a lateral superlift SSL or Y guying
  • Y guying is a lateral guying of the telescopic boom, the arrangement of which can sometimes significantly increase its load capacity.
  • its lateral movements induced, for example, by wind and solar radiation can be reduced in this way, which ultimately also increases the precision when working with a mobile crane equipped in this way.
  • the transport device can advantageously be a semi-trailer. This can be made entirely for the intended purpose or can be based on a commercially available semi-trailer. By selecting a semi-trailer that is suitable in terms of the required dimensions and loads, it can be supplemented by the necessary components, for example, and thus expanded into a transport device according to the invention in an economical manner.
  • the invention advantageously provides active pivoting of the at least one loading arm.
  • a combination of active drive of the tilting drive and of the at least one loading arm is particularly preferred.
  • the preferred active pivotability of the at least one loading arm allows precise guidance of the attachment coupled to it, which is of great importance in view of the possible dimensions and weight of such an attachment, such as a guying device.
  • a total of two loading arms can be provided, which are then arranged pivotably on the transport device as a loading arrangement.
  • This enables a better, more even weight distribution of the attachment, such as a guying device, on the loading arms.
  • the loading arms and attachment can then be positioned relative to one another during use in such a way that the attachment is securely supported essentially by both loading arms while it is being loaded.
  • the loading arms can be controlled in such a way that their respective pivoting movement(s) can be carried out either synchronously with one another and/or independently of one another. On the one hand, this can be done by rigidly connecting both loading arms, which inevitably causes them to be mechanically synchronized.
  • the mobility of the two loading arms which is otherwise independent of one another, can be controlled in such a way that they can be moved either synchronously with one another or independently of one another, as required.
  • their independent mobility allows a Fine adjustment in its alignment, which can be particularly advantageous when the attachment transport unit is not ideally aligned with respect to the telescopic boom of a mobile crane.
  • a pivot point that is as low as possible is considered advantageous.
  • the transport device can have a loading area which faces an attached part that is picked up and is essentially horizontally aligned, such as a guying device.
  • the loading arm(s) via an axis of rotation below the loading area, so that it/they can be pivoted about the axis of rotation.
  • This enables the lowest possible center of gravity for the proportionate introduction of the weight of a picked-up attachment into the transport device and from there onto the ground, for example via a chassis having wheels and/or chains.
  • the low arrangement of the axis of rotation enables its/their greater length, as a result of which the translatory displacement of an attached attachment can be correspondingly increased. In other words, a greater range can be achieved in relation to the displacement of an add-on part parallel to the transport device.
  • the attachment transport unit can preferably have a swivel drive in the form of a linear drive integrated between the at least one loading arm and the transport device.
  • a swivel drive can be arranged between each of these loading arms and the transport device.
  • the linear drive within the meaning of the invention can be all types of such drives, which are, for example, pressure-actuated, in particular pneumatically or preferably hydraulically driven.
  • the linear drive can be a hydraulic cylinder, for example.
  • this can also be driven via a gear, in which a rotary movement of a motor is converted into a translatory movement of the Linear drive is implemented, such as by means of a roller or ball screw drive.
  • a pivoting movement of the loading arm(s) is then based on a change in length of the linear drive(s).
  • the loading arm or the preferably two loading arms can each be divided into a lower arm section and an upper arm section. Said arm sections are then connected to one another via a joint so that they can be folded relative to one another.
  • the foldability of the loading arm or arms enables an attachment to be guided even more precisely, since the additional joint provides a further degree of freedom with regard to the mobility of the at least one loading arm.
  • the attached attachment can also be lowered in a position of the at least one loading arm by bending it around the joint, which would otherwise not be possible due to the otherwise specified, in particular shortest, length and the circular path of a pivoting movement of the loading arm thus specified.
  • the at least one loading arm has an articulated drive, which is then located between its two arm sections.
  • a joint drive it can be designed, for example, in the form of a length-adjustable linear drive in order to be able to carry out the necessary folding movement of the loading arm around its joint.

  • its upper arm section can have said coupling area and be connected to a first end of the swivel drive in a force-transmitting manner, while a second end opposite the first end of the swivel drive is coupled to the transport device.
  • the coupling between swivel drive and transport device can be done, for example, via a bearing, which is then, for example, on or under the loading area of the Transport device is arranged.
  • its end section having the free supporting end can preferably be angled towards a side of the loading arm facing away from the swivel drive.
  • the loading arm in particular the respective loading arm, is designed such that it can be changed in length and is therefore telescopic. This means that its length can be changed as required, which means that, for example, a larger distance between the transport device and the mobile crane can be bridged accordingly. Alternatively or in combination with this, such an add-on part can also be further accommodated on the transport device, if necessary.
  • the loading arm can be designed in several parts, for example in the form of multi-section segments.

  • it can preferably be coupled to a suitable towing vehicle--such as a semi-trailer truck--which carries the attached part transport unit that is then pulled and/or pushed with it.
  • the at least one loading arm or the loading arrangement can be designed in such a way that it can be operated from an area that is not necessarily in the immediate vicinity.
  • the drives arranged on vehicles for moving such devices are usually operated, for example, via an operating unit arranged in and/or on the vehicle itself.
  • the invention provides the advantageous possibility of operating the loading arm(s) from outside. This means operation from outside a vehicle cabin, which in the case of a self-propelled mobile transport device, for example, can be part of the add-on transport unit configured in this way.
  • said vehicle cabin can be part of this towing vehicle.
  • the loading arm and/or the tipping device can be controlled by means of a wireless or wired operating unit.
  • a wireless or wired operating unit provides the greatest possible flexibility for a person operating the attachment transport unit.
  • the possibility of physical distance from the attachment transport unit offers a much better overview in order to ensure extremely precise control of the loading arm and/or the tilting device despite the sometimes considerable dimensions of mobile cranes and, for example, their main boom.

Description

Die Erfindung betrifft ein Fahrzeugkransystem, umfassend einen Fahrzeugkran mit einem an seinem Teleskopausleger montierbaren beziehungsweise von diesem demontierbaren Anbauteil, insbesondere Abspanneinrichtung, sowie eine zum Transport des Anbauteils ausgebildete Anbauteil-Transporteinheit. Weiterhin betrifft die Erfindung ein Verfahren zum Umsetzen eines Anbauteils in Form einer Abspanneinrichtung von einer Transportvorrichtung einer Anbauteil-Transporteinheit auf einen Teleskopausleger eines Fahrzeugkrans sowie ein Verfahren zum Umsetzen eines Anbauteils in Form einer Abspanneinrichtung von einem Teleskopausleger, insbesondere von dessen Grundkasten, eines Fahrzeugkrans auf eine Transportvorrichtung einer Anbauteil-Transporteinheit.The invention relates to a vehicle crane system, comprising a vehicle crane with an attachment that can be mounted on or removed from its telescopic boom, in particular a guying device, and an attachment transport unit designed to transport the attachment. Furthermore, the invention relates to a method for transferring an attachment in the form of a guying device from a transport device of an attachment transport unit to a telescopic boom of a mobile crane and a method for transferring an attachment in the form of a guying device from a telescopic boom, in particular from its base box, of a mobile crane to a Transport device of an attachment transport unit.

Üblicherweise sind die Einsetzbarkeit von Fahrzeugkranen, insbesondere Mobilkranen, bestimmende Faktoren durch deren bauliche Ausgestaltung festgelegt. Technische Kenngrößen wie Tragfähigkeit, Arbeitsradius und Hubhöhe ergeben sich dabei maßgeblich aus dem Aufbau des jeweiligen Teleskopauslegers. Durch den Einsatz von mit dem Teleskopausleger koppelbaren Anbauteilen lassen sich die Kenngrößen eines Fahrzeugkrans mitunter verändern, um etwa dessen Tragfähigkeit zu erhöhen und die elastische Durchbiegung seines Teleskopauslegers zu reduzieren. Hierzu sind zusätzliche Anbauteile in Form wenigstens einer Abspanneinrichtung bekannt, durch deren Anordnung beispielsweise eine Hebelarmreduzierung des Teleskopauslegers erreichbar ist. Die hierdurch mögliche Traglaststeigerung ergibt sich zumeist durch Kombination mit einem zusätzlichen Gegengewicht und entsprechenden Umlenkungen über die Abspanneinrichtung.The usability of mobile cranes, in particular mobile cranes, is usually determined by their structural design. Technical characteristics such as load capacity, working radius and lifting height result primarily from the structure of the respective telescopic boom. By using attachments that can be coupled to the telescopic boom, the parameters of a mobile crane can sometimes be changed, for example to increase its load-bearing capacity and reduce the elastic deflection of its telescopic boom. For this purpose, additional add-on parts are known in the form of at least one guying device, the arrangement of which, for example, can achieve a reduction in the lever arm of the telescopic boom. The increase in load capacity that is possible as a result is usually the result of a combination with an additional counterweight and corresponding deflections via the guying device.

Durch das zumeist sehr hohe Gewicht solcher Fahrzeugkrane gelangen diese oftmals nur teilzerlegt an ihren jeweiligen Einsatzort, um für das öffentliche Straßennetz festgelegte Höchstwerte hinsichtlich Achslast und Fahrzeuggewicht einhalten zu können. Die deutsche Offenlegungsschrift DE 198 23 380 A1 offenbart in diesem Zusammenhang eine Kranausleger Transporteinheit mit einer mobilen Transportvorrichtung in Form eines Sattelaufliegers für den Transport eines von einem Fahrzeugkran getrennten Hauptauslegers.Due to the usually very high weight of such mobile cranes, they often arrive at their respective place of use only partially dismantled in order to be able to comply with the maximum values specified for the public road network in terms of axle load and vehicle weight. The German Offenlegungsschrift DE 198 23 380 A1 discloses in this context a crane boom transport unit with a mobile transport device in the form of a semi-trailer for transporting a main boom separate from a mobile crane.

Unabhängig hiervon weisen die in Rede stehenden zusätzlichen Anbauteile zumeist Abmessungen und Gewichte auf, die deren separaten Transport erfordern. Hierzu sind geeignete zusätzliche Transportvorrichtungen notwendig, um diese zu ihrem jeweiligen Einsatzort hin und von diesem weg zu befördern. Die anschließende Verlagerung auf den Teleskopausleger und wieder zurück erfordert eine zusätzliche mobile Hebevorrichtung, mit der das jeweilige Anbauteil vor Ort aufgenommen und umgesetzt werden kann. Angesichts der hierfür erforderlichen Aufwendung bieten der Transport und die Umsetzung derartiger Anbauteile daher noch Raum für Verbesserungen.Irrespective of this, the additional add-on parts in question usually have dimensions and weights that require them to be transported separately. For this purpose, suitable additional transport devices are necessary in order to transport them to and from their respective place of use. The subsequent relocation to the telescopic boom and back again requires an additional mobile lifting device with which the respective attachment can be picked up and moved on site. In view of the expenditure required for this, the transport and the implementation of such add-on parts therefore still offer room for improvement.

Des Weiteren ist aus der gattungsgemäßen Offenlegungsschrift WO 2005/092775 A1 bereits ein Fahrzeugkransystem nach Oberbegriff des Anspruchs 1 und ein Verfahren zum An- und Abbauen einer Abspanneinrichtung an einen Teleskopausleger eines Fahrzeugkrans bekannt. In einem ersten Schritt wird die auf einem Sattelauflieger herantransportierte Abspanneinrichtung von dem Fahrzeugkran angehoben und hierdurch an dem Sattelauflieger und der Abspanneinrichtung gelenkig angebundene Stützbeine aus einer horizontalen Transportstellung in einen nahezu vertikale Stützstellung aufgestellt. Dann werden die Stützbeine über Hilfsbeine in der aufgestellten Stützstellung abgestützt und der Fahrzeugkran von der Abspanneinrichtung gelöst. In der Stützstellung ist der Teleskopausleger weitestgehend horizontal und parallel zu dem Sattelauflieger sowie mit Abstand zu diesem aufgestellt. Anschließend fährt der Fahrzeugkran mit seinem Teleskopausleger unter die Abspanneinrichtung und zwischen die Stützbeine und Hilfsbeine ein. Durch Aufwippen des Teleskopauslegers wird dann die Abspanneinrichtung von dem Teleskopausleger aufgenommen. Dann wird die Abspanneinrichtung an dem Teleskopausleger befestigt und die Stützbeine und Hilfsbeine werden gelöst.Furthermore, from the generic disclosure document WO 2005/092775 A1 a vehicle crane system according to the preamble of claim 1 and a method for attaching and detaching a guying device to a telescopic boom of a mobile crane are already known. In a first step, the guying device transported on a semi-trailer is lifted by the mobile crane and thereby articulated support legs connected to the semi-trailer and the guying device are set up from a horizontal transport position into an almost vertical supporting position. Then the support legs are supported by auxiliary legs in the erected support position and the mobile crane is detached from the guying device. In the support position, the telescopic boom is set up largely horizontally and parallel to the semi-trailer and at a distance from it. The mobile crane then moves under the guying device and between the support legs and auxiliary legs with its telescopic boom. By luffing up the telescopic boom, the guying device is then picked up by the telescopic boom. Then the guying device is attached to the telescopic boom and the support legs and auxiliary legs are released.

Ferner zeigt die deutsche Offenlegungsschrift DE 197 30 361 A1 ein Verfahren zum An- und Abbauen eines Gegenauslegers an einen Teleskopausleger eines Fahrzeugkrans. Hierbei wird der Gegenausleger von einem Sattelauflieger mit einem Hilfskran auf den horizontal ausgerichteten Teleskopausleger abgelegt und dort an einem Oberwagen des Fahrzeugkrans befestigt. Außerdem zeigt die Offenlegungsschrift DE 28 33 535 A1 ein Verfahren zum An- und Abbauen eines Teleskopauslegers an einen Oberwagen eines Fahrzeugkrans. Hierbei wird der auf einem Sattelauflieger ruhende Teleskopausleger über schwenkbare Stützbeine aus einer horizontalen Transportstellung in eine ebenfalls horizontale Stützstellung angehoben und dann von dem Sattelauflieger in Richtung des Oberwagens verfahren, um dort angebolzt zu werden.Furthermore, the German Offenlegungsschrift shows DE 197 30 361 A1 a method for attaching and detaching a counterjib to a telescopic boom of a mobile crane. Here, the counter-jib is placed from a semi-trailer with an auxiliary crane onto the horizontally aligned telescopic jib and fixed there to an upper carriage of the mobile crane. In addition, the disclosure document shows DE 28 33 535 A1 a method for attaching and detaching a telescopic boom to an upper structure of a mobile crane. Here, the telescopic boom resting on a semi-trailer is extended via pivoting support legs a horizontal transport position in a likewise horizontal support position and then moved by the semi-trailer in the direction of the superstructure in order to be bolted there.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, die bisher bekannten Vorrichtungen zum Transport und zum Umsetzen eines wie zuvor beschriebenen zusätzlichen Anbauteils für den Teleskopausleger eines Fahrzeugkrans so zu verbessern, dass diese eine insgesamt wirtschaftlichere und praktikablere Durchführung des Transports sowie der Umsetzung ermöglichen. Weiterhin sollen zwei Verfahren aufgezeigt werden, durch die insbesondere das Umsetzen eines solchen Anbauteils vereinfacht wird.The present invention is therefore based on the object of improving the previously known devices for transporting and relocating an additional add-on part as described above for the telescopic boom of a mobile crane in such a way that they allow the transport and relocation to be carried out more economically and practicably overall. Furthermore, two methods are to be shown, which in particular simplify the conversion of such an add-on part.

Der Vorrichtungsteil dieser Aufgabe wird durch ein Fahrzeugkransystem mit den Merkmalen von Anspruch 1 gelöst. Die Lösung des Verfahrensteils dieser Aufgabe besteht in einem Verfahren mit den Merkmalen von Anspruch 8 sowie in einem Verfahren mit den Merkmalen von Anspruch 12. In den jeweils abhängigen Ansprüchen 2 bis 7 sowie 9 bis 11 und 13 bis 15 sind vorteilhafte Ausgestaltungen der Erfindung angegeben.The device part of this object is solved by a vehicle crane system having the features of claim 1. The solution to the method part of this object consists in a method having the features of claim 8 and in a method having the features of claim 12. Advantageous refinements of the invention are specified in the respective dependent claims 2 to 7 as well as 9 to 11 and 13 to 15.

Das Fahrzeugkransystem, umfassend einen Fahrzeugkran mit einem an seinem Teleskopausleger montierbaren beziehungsweise von diesem demontierbaren Anbauteil, insbesondere Abspanneinrichtung, sowie eine zum Transport des Anbauteils ausgebildete und erfindungsgemäße Anbauteil-Transporteinheit umfasst hierzu eine für den Transport des Anbauteils ausgebildete mobile Transportvorrichtung, welche wenigstens einen Verladearm besitzt. Der Verladearm ist so ausgestaltet, dass sein freies Tragende mit dem auf die Transportvorrichtung aufgenommenen beziehungsweise aufzunehmenden Anbauteil koppelbar ist. Der Verladearm ist derart beweglich an der Transportvorrichtung angeordnet, dass das mit dessen freiem Tragende gekoppelte Anbauteil zwischen der Transportvorrichtung und dem Teleskopausleger umsetzbar ist. Weiterhin besitzt die Transportvorrichtung eine Kippeinrichtung, welche dazu ausgebildet ist, ein auf der Transportvorrichtung aufgenommenes beziehungsweise aufzunehmendes Anbauteil einseitig anzuheben und abzusenken.The mobile crane system, comprising a mobile crane with an attachment that can be mounted on or removed from its telescopic boom, in particular a guying device, and an attachment transport unit designed to transport the attachment and according to the invention, includes a mobile transport device designed to transport the attachment, which has at least one loading arm . The loading arm is designed in such a way that its free supporting end can be coupled to the add-on part which is or is to be mounted on the transport device. The loading arm is movably arranged on the transport device in such a way that the attachment coupled to its free supporting end can be moved between the transport device and the telescopic boom. Furthermore, the transport device has a tilting device which is designed to raise and lower on one side an attachment that is received or is to be received on the transport device.

Der sich aus der Erfindung ergebende Vorteil liegt primär in der zur kombinierten Nutzung dienenden Ausgestaltung der Anbauteil-Transporteinheit, welche über die zum separaten Befördern eines Anbauteils dienende Transportvorrichtung hinaus nunmehr auch die geeigneten Mittel zu dessen Umsetzen beinhaltet. Hierdurch entfällt die sonst übliche Notwendigkeit zur Nutzung wenigstens zweier separater Vorrichtungen, von denen eine dem reinen Transport des Anbauteils und die andere der Verlagerung des Anbauteils zwischen dem Teleskopausleger und der Transportvorrichtung dient. Aufgrund der Reduzierung der erforderlichen Vorrichtungen auf eine einzelne Einheit ermöglicht die erfindungsgemäße Anbauteil-Transporteinheit eine überaus wirtschaftliche und praktikable Durchführung der zum Befördern und Anbringen eines solchen Anbauteils am Teleskopausleger eines Fahrzeugkrans, insbesondere Mobilkrans, erforderlichen Maßnahmen.The advantage resulting from the invention lies primarily in the combined Design of the attachment transport unit serving the purpose of use, which, in addition to the transport device serving for the separate transport of an attachment, now also contains the suitable means for its conversion. This eliminates the otherwise usual need to use at least two separate devices, one of which serves purely to transport the attachment and the other to relocate the attachment between the telescopic boom and the transport device. Due to the reduction of the required devices to a single unit, the attachment transport unit according to the invention enables the measures required for transporting and attaching such an attachment to the telescopic boom of a mobile crane, in particular a mobile crane, to be carried out extremely economically and practicably.

Nach einer bevorzugten Weiterbildung des grundsätzlichen Erfindungsgedankens kann die Kippeinrichtung der Anbauteil-Transporteinheit wenigstens eine Stützanordnung sowie einen Kipp-Antrieb besitzen. In vorteilhafter Weise kann es sich bei dem Kipp-Antrieb um einen Linearantrieb handeln oder der Kipp-Antrieb kann zumindest einen solchen Linearantrieb enthalten. Der Vorteil eines Linearantriebs liegt in seiner im Vergleich zu anderen Antrieben überaus kompakten Bauweise bei gleichzeitig hoher Leistung. Die Stützanordnung und der zur Kopplung mit einem ersten Endabschnitt des Anbauteils vorgesehene Kipp-Antrieb sind dazu ausgebildet, einen dem ersten Endabschnitt gegenüberliegenden zweiten Endabschnitt des mit dem Kipp-Antrieb gekoppelten und zumindest bereichsweise an der Stützanordnung abgestützten Anbauteils anzuheben beziehungsweise abzusenken. Hierzu kann sich das Anbauteil zumindest teilweise in vorteilhafter Weise horizontal an der Stützanordnung abstützen, während es beispielsweise durch eine Längenänderung des Kipp-Antriebs um die Stützanordnung herum begrenzt verschwenkbar ist.According to a preferred development of the basic idea of the invention, the tilting device of the attachment transport unit can have at least one support arrangement and a tilting drive. The tilting drive can advantageously be a linear drive or the tilting drive can contain at least one such linear drive. The advantage of a linear drive lies in its extremely compact design compared to other drives, while at the same time offering high performance. The support arrangement and the tilting drive provided for coupling to a first end section of the attachment are designed to raise or lower a second end section, opposite the first end section, of the attachment coupled to the tilting drive and supported at least in regions on the support arrangement. For this purpose, the add-on part can advantageously be supported horizontally at least partially on the support arrangement, while it can be pivoted around the support arrangement to a limited extent, for example, due to a change in length of the tilting drive.

Erfindungsgemäß kann der wenigstens eine Verladearm derart verschwenkbar an der Transportvorrichtung angeordnet sein, dass ein aufzuladendes beziehungsweise abzuladendes Anbauteil auf einem Pfad beziehungsweise einer Bahn bewegbar ist, welche/r einen Bewegungsanteil sowohl in eine Vertikalrichtung als auch in eine Horizontalrichtung enthält. Am Beispiel einer Abspanneinrichtung, insbesondere eines seitlichen Superlifts, ausgebildeten Anbauteils ist hierdurch ein einfaches Heraufsowie Herabbewegen auf beziehungsweise von der Transportvorrichtung gegeben, ohne dass es hierfür einer vor Ort zusätzlich bereitzustellenden Vorrichtung zum Umsetzen des Anbauteils bedarf.According to the invention, the at least one loading arm can be arranged pivotably on the transport device in such a way that an attachment to be loaded or unloaded can be moved on a path or a path which contains a movement component both in a vertical direction and in a horizontal direction. Using the example of a guying device, in particular a lateral superlift, designed add-on part, this makes it easy to move up and down on and off the transport device without requiring an additional device to be provided on site for this purpose Converting the attachment required.

Der zum Verladen eines Anbauteils, wie beispielsweise einer Abspanneinrichtung, insbesondere bevorzugt eines seitlichen Superlifts, verschwenkbare wenigstens eine Verladearm kann in vorteilhafter Weise so an der Transportvorrichtung angeordnet sein, dass ein mit dessen freiem Tragende zumindest indirekt gekoppeltes und gleichzeitig zumindest abschnittsweise oder bereichsweise auf dem Teleskopausleger eines Fahrzeugkrans abgestütztes Anbauteil entsprechend beweglich ist. Durch eine Schwenkbewegung des Verladearms ist es nunmehr möglich, das zumindest teilweise auf einem Teleskopausleger abgestützte Anbauteil zumindest einseitig anzuheben und aufgrund seiner dann kombinierten translatorischen sowie begrenzt rotatorischen Bewegung relativ zum Teleskopausleger auf diesem zu verlagern, insbesondere gleitend und/oder rollend.The at least one loading arm that can be pivoted for loading an attachment, such as a guying device, particularly preferably a lateral superlift, can advantageously be arranged on the transport device in such a way that a load arm is at least indirectly coupled to its free supporting end and at the same time at least partially or partially on the telescopic boom a vehicle crane supported attachment is movable accordingly. By pivoting the loading arm, it is now possible to lift the attachment, which is at least partially supported on a telescopic boom, at least on one side and to move it relative to the telescopic boom due to its then combined translational and limited rotational movement, in particular sliding and/or rolling.

Ursächlich hierfür ist die während dieser Bewegung über zwei voneinander entfernte Bereiche erfolgende Lagerung des Anbauteils, nämlich an dem wenigstens einen Verladearm und dem Teleskopausleger. Hierdurch kann dessen auf dem Teleskopausleger abgestützter Endbereich während der Schwenkbewegung des Verladearms quasi parallel zum Teleskopausleger verschoben werden, während sein gegenüberliegender Endbereich auf einer Kreisbahn des an der Transportvorrichtung angelenkten Verladearms bewegt wird.The reason for this is the mounting of the add-on part, which takes place during this movement over two areas spaced apart from one another, namely on the at least one loading arm and the telescopic boom. As a result, its end region supported on the telescopic boom can be shifted more or less parallel to the telescopic boom during the pivoting movement of the loading arm, while its opposite end region is moved on a circular path of the loading arm articulated on the transport device.

Die erfindungsgemäße Ausgestaltung sieht vor, dass das an einem Teleskopausleger eines Fahrzeugkrans abgestützte und mit dem Kipp-Antrieb der Kippeinrichtung gekoppelte Anbauteil durch eine Längenänderung des Kipp-Antriebs in eine Bewegung versetzbar ist, die abhängig von der Richtung der Längenänderung des Kipp-Antriebs dem Aufsetzen oder Absetzen des Anbauteils in Bezug auf den Teleskopausleger dient. In vorteilhafter Weise kann sich das Anbauteil dabei an einem Grundkasten des Teleskopauslegers abstützen. Hiernach ist es einerseits möglich, das Anbauteil in eine relativ zur Transportvorrichtung erfolgende, kombinierte translatorische sowie begrenzt rotatorische erste Aufsetz-Bewegung weg von der Transportvorrichtung, insbesondere hin zum Fahrzeugkran, zu versetzen. Durch eine Richtungsumkehr der Längenänderung des Kipp-Antriebs ist es andererseits möglich, das Anbauteil in eine ebenfalls relativ zur Transportvorrichtung erfolgende, kombinierte translatorische sowie begrenzt rotatorische zweite Absetz-Bewegung hin zur Transportvorrichtung, insbesondere weg vom Fahrzeugkran, zu versetzen.The configuration according to the invention provides that the attachment supported on a telescopic boom of a mobile crane and coupled to the tilting drive of the tilting device can be set in motion by a change in length of the tilting drive, which depends on the direction of the change in length of the tilting drive when it is placed or deducting the attachment in relation to the telescopic boom is used. The attachment can advantageously be supported on a base box of the telescopic boom. According to this, it is possible on the one hand to set the attachment in a combined translatory and limited rotational first placement movement relative to the transport device away from the transport device, in particular towards the vehicle crane. On the other hand, by reversing the direction of the change in length of the tilting drive, it is possible to move the add-on part into a combined translatory and limited rotary second setting-down movement, which also takes place relative to the transport device to the transport device, in particular away from the mobile crane.

Weiterhin sieht die erfindungsgemäße Ausgestaltung vor, dass das zumindest abschnittsweise auf dem Teleskopausleger des Fahrzeugkrans abgelegte und mit dem freien Tragende des wenigstens einen Verladearms gekoppelte Anbauteil durch eine Bewegung und/oder Längenänderung des Verladearms in eine von der Schwenkrichtung und/oder Richtung der Längenänderung des Verladearms abhängige und dabei dem Aufsetzen oder Absetzen des Anbauteils in Bezug auf den Teleskopausleger dienende Bewegung versetzbar ist. Hiernach ist es einerseits möglich, das Anbauteil in eine relativ zum Teleskopausleger erfolgende, kombinierte translatorische sowie begrenzt rotatorische erste Absetz-Bewegung hin zur Transportvorrichtung, insbesondere weg vom Fahrzeugkran, zu versetzen. Durch eine Richtungsumkehr der Schwenkbewegung und/oder der Längenänderung des wenigstens einen Verladearms ist es andererseits möglich, das Anbauteil in eine ebenfalls relativ zum Teleskopausleger erfolgende, kombinierte translatorische sowie begrenzt rotatorische zweite Aufsetz-Bewegung weg von der Transportvorrichtung, insbesondere hin zum Fahrzeugkran, zu versetzen.Furthermore, the configuration according to the invention provides that the attachment, which is placed at least in sections on the telescopic boom of the mobile crane and is coupled to the free supporting end of the at least one loading arm, is moved by a movement and/or change in length of the loading arm in one of the pivoting direction and/or direction of the change in length of the loading arm dependent and thereby the attachment or detachment of the attachment in relation to the telescopic boom serving movement can be displaced. According to this, it is possible on the one hand to set the attachment in a combined translatory and limited rotational first setting-down movement relative to the telescopic boom towards the transport device, in particular away from the mobile crane. On the other hand, by reversing the direction of the pivoting movement and/or the change in length of the at least one loading arm, it is possible to set the attachment in a combined translatory and limited rotational second placement movement, also relative to the telescopic boom, away from the transport device, in particular towards the mobile crane .

In beiden zuvor beschriebenen Fällen gelangt das Anbauteil in vorteilhafter Weise ohne das Hinzuziehen einer separat beizubringenden Vorrichtung zumindest teilweise von der Transportvorrichtung auf den Teleskopausleger oder von dem Teleskopausleger auf die Transportvorrichtung.In both of the cases described above, the add-on part advantageously moves at least partially from the transport device onto the telescopic jib or from the telescopic jib onto the transport device without using a device that has to be provided separately.

Im Rahmen der Erfindung wird es als besonders vorteilhaft angesehen, wenn es sich bei dem mit der erfindungsgemäßen Anbauteil-Transporteinheit zu transportierenden und/oder umzusetzenden Anbauteil um eine Abspanneinrichtung handelt. Besonders bevorzugt kann es sich dabei um wenigstens einen seitlichen Superlift handeln. Bei einem derartigen seitlichen Superlift (SSL- oder auch Y Abspannung) handelt es sich um eine seitliche Abspannung des Teleskopauslegers, durch deren Anordnung sich dessen Traglast mitunter deutlich erhöhen lässt. Überdies können so auch insbesondere bei langen Teleskopauslegern dessen beispielsweise durch Wind und Sonneneinstrahlung induzierten seitlichen Bewegungen reduziert werden, was letztlich auch die Präzision in der Arbeit mit einem so ausgestatteten Fahrzeugkran erhöht.Within the scope of the invention, it is considered to be particularly advantageous if the attachment to be transported and/or repositioned with the attachment transport unit according to the invention is a guying device. It can particularly preferably be at least one lateral superlift. Such a lateral superlift (SSL or Y guying) is a lateral guying of the telescopic boom, the arrangement of which can sometimes significantly increase its load capacity. In addition, especially in the case of long telescopic booms, its lateral movements induced, for example, by wind and solar radiation can be reduced in this way, which ultimately also increases the precision when working with a mobile crane equipped in this way.

Vorteilhafterweise kann es sich bei der Transportvorrichtung um einen Sattelauflieger handeln. Dieser kann vollständig für den angedachten Zweck gefertigt sein oder einen handelsüblichen Sattelauflieger als Basis aufweisen. Durch die Auswahl eines in Bezug auf die erforderlichen Abmessungen und Traglasten passenden Sattelaufliegers kann dieser beispielsweise um die erforderlichen Komponenten ergänzt und so in wirtschaftlicher Weise zu einer erfindungsgemäßen Transportvorrichtung ausgebaut sein.The transport device can advantageously be a semi-trailer. This can be made entirely for the intended purpose or can be based on a commercially available semi-trailer. By selecting a semi-trailer that is suitable in terms of the required dimensions and loads, it can be supplemented by the necessary components, for example, and thus expanded into a transport device according to the invention in an economical manner.

Auch wenn der für das Umsetzen eines Anbauteils notwendige Antrieb einzig auf Basis des Kipp-Antriebs in Kombination mit einem rein passiven Verschwenken des wenigstens einen Verladearms erfolgen könnte, sieht die Erfindung in vorteilhafter Weise eine demgegenüber aktive Verschwenkbarkeit des wenigstens einen Verladearms vor. Besonders bevorzugt ist eine Kombination aus aktivem Antrieb des Kipp-Antriebs und des wenigstens einen Verladearms vorgesehen. Insbesondere die bevorzugte aktive Verschwenkbarkeit des wenigstens einen Verladearms lässt eine präzise Führung des mit diesem gekoppelten Anbauteils zu, was im Hinblick auf die möglichen Abmessungen und das Gewicht eines solchen Anbauteils, wie etwa einer Abspanneinrichtung, von hoher Bedeutung ist.Even if the drive required for moving an attachment could be based solely on the tilt drive in combination with purely passive pivoting of the at least one loading arm, the invention advantageously provides active pivoting of the at least one loading arm. A combination of active drive of the tilting drive and of the at least one loading arm is particularly preferred. In particular, the preferred active pivotability of the at least one loading arm allows precise guidance of the attachment coupled to it, which is of great importance in view of the possible dimensions and weight of such an attachment, such as a guying device.

Gemäß einer besonders bevorzugten Weiterbildung der Erfindung können insgesamt zwei Verladearme vorgesehen sein, die dann als Verladeanordnung schwenkbar an der Transportvorrichtung angeordnet sind. Dies ermöglicht eine bessere, da gleichmäßigere Gewichtsverteilung des Anbauteils, wie etwa einer Abspanneinrichtung, auf die Verladearme. Zudem können Verladearme und Anbauteil im Einsatz dann so zueinander positioniert sein, dass das Anbauteil während seiner Verladung im Wesentlichen über beide Verladearme sicher gestützt ist. Die Verladearme können so angesteuert sein, dass deren jeweilige Schwenkbewegung/en entweder synchron zueinander und/oder voneinander unabhängig ausführbar sind. Dies kann zum einen durch eine starre Verbindung beider Verladearme erfolgen, was deren zwangsläufig mechanische Synchronisierung bewirkt. Andererseits kann die ansonsten voneinander unabhängige Beweglichkeit beider Verladearme so angesteuert sein, dass diese je nach Bedarf entweder synchron zueinander oder voneinander unabhängig beweglich sind. Je nach Kopplungsart der Verladearme, beispielsweise mit einer Abspanneinrichtung, ermöglicht insbesondere deren voneinander unabhängige Beweglichkeit eine Feinjustierung in dessen Ausrichtung, was besonders bei einer nicht ideal ausgerichteten Aufstellung der Anbauteil-Transporteinheit gegenüber dem Teleskopausleger eines Fahrzeugkrans vorteilhaft sein kann. Hinsichtlich der Anordnung des wenigstens einen verschwenkbaren Verladearms oder der beiden verschwenkbaren Verladearme wird ein möglichst tiefliegender Gelenkpunkt als vorteilhaft angesehen. So kann die Transportvorrichtung eine Ladefläche besitzen, welche einem aufgenommenen und dabei im Wesentlichen horizontal ausgerichteten Anbauteil, wie etwa einer Abspanneinrichtung, zugewandt ist. In diesem Zusammenhang wird vorgeschlagen, den oder die Verladearm/e über eine Drehachse unterhalb der Ladefläche anzulenken, so dass diese/r um die Drehachse herum schwenkbar ist. Dies ermöglicht einen möglichst tiefen Schwerpunkt für die anteilige Gewichtseinleitung eines aufgenommenen Anbauteils in die Transportvorrichtung und von dort aus auf den Untergrund, beispielsweise über ein Räder und/oder Ketten aufweisendes Fahrwerk. Gegenüber einer auf oder über der Ladefläche möglichen Anlenkung des/der Verladearms/Verladearme ermöglicht die tiefe Anordnung der Drehachse dessen/deren größere Länge, wodurch sich die translatorische Verlagerung eines aufgenommenen Anbauteils entsprechend vergrößern lässt. Mit anderen Worten lässt sich so eine größere Reichweite in Bezug auf die Verlagerung eines Anbauteils parallel zur Transportvorrichtung erreichen.According to a particularly preferred development of the invention, a total of two loading arms can be provided, which are then arranged pivotably on the transport device as a loading arrangement. This enables a better, more even weight distribution of the attachment, such as a guying device, on the loading arms. In addition, the loading arms and attachment can then be positioned relative to one another during use in such a way that the attachment is securely supported essentially by both loading arms while it is being loaded. The loading arms can be controlled in such a way that their respective pivoting movement(s) can be carried out either synchronously with one another and/or independently of one another. On the one hand, this can be done by rigidly connecting both loading arms, which inevitably causes them to be mechanically synchronized. On the other hand, the mobility of the two loading arms, which is otherwise independent of one another, can be controlled in such a way that they can be moved either synchronously with one another or independently of one another, as required. Depending on the type of coupling of the loading arms, for example with a guying device, their independent mobility allows a Fine adjustment in its alignment, which can be particularly advantageous when the attachment transport unit is not ideally aligned with respect to the telescopic boom of a mobile crane. With regard to the arrangement of the at least one pivotable loading arm or the two pivotable loading arms, a pivot point that is as low as possible is considered advantageous. For example, the transport device can have a loading area which faces an attached part that is picked up and is essentially horizontally aligned, such as a guying device. In this context, it is proposed to articulate the loading arm(s) via an axis of rotation below the loading area, so that it/they can be pivoted about the axis of rotation. This enables the lowest possible center of gravity for the proportionate introduction of the weight of a picked-up attachment into the transport device and from there onto the ground, for example via a chassis having wheels and/or chains. Compared to a possible articulation of the loading arm(s) on or above the loading area, the low arrangement of the axis of rotation enables its/their greater length, as a result of which the translatory displacement of an attached attachment can be correspondingly increased. In other words, a greater range can be achieved in relation to the displacement of an add-on part parallel to the transport device.

Hinsichtlich des Antriebs des/der Verladearms/Verladearme sind diverse Ausgestaltungen denkbar, wie etwa in Form wenigstens eines im Bereich des/der Schwenklager/s angeordneten Drehantriebs. Bevorzugt kann die Anbauteil-Transporteinheit einen Schwenk-Antrieb in Form eines zwischen dem wenigstens einen Verladearm und der Transportvorrichtung eingegliederten Linearantriebs besitzen. Bei der bevorzugten Ausführung mit zwei Verladearmen kann zwischen jedem dieser Verladearme und der Transportvorrichtung ein solcher Schwenk-Antrieb angeordnet sein.With regard to the drive of the loading arm(s), various configurations are conceivable, such as in the form of at least one rotary drive arranged in the area of the swivel bearing(s). The attachment transport unit can preferably have a swivel drive in the form of a linear drive integrated between the at least one loading arm and the transport device. In the preferred embodiment with two loading arms, such a swivel drive can be arranged between each of these loading arms and the transport device.

Bei dem Linearantrieb im Sinne der Erfindung kann es sich um alle Arten solcher Antriebe handeln, welche beispielsweise druckbetätigt, insbesondere pneumatisch oder bevorzugt hydraulisch angetrieben sind. Hiernach kann es sich bei dem Linearantrieb beispielsweise um einen Hydraulikzylinder handeln. Ergänzend oder alternativ kann dieser auch über ein Getriebe angetrieben sein, bei dem eine rotatorische Bewegung eines Motors in eine translatorische Bewegung des Linearantriebs umgesetzt wird, wie beispielsweise mittels eines Rollen- oder Kugelgewindegetriebes. In jedem Fall basiert eine Schwenkbewegung des/der Verladearms/Verladearme dann auf einer Längenänderung des/der Linearantriebs/Linearantriebe.The linear drive within the meaning of the invention can be all types of such drives, which are, for example, pressure-actuated, in particular pneumatically or preferably hydraulically driven. According to this, the linear drive can be a hydraulic cylinder, for example. In addition or as an alternative, this can also be driven via a gear, in which a rotary movement of a motor is converted into a translatory movement of the Linear drive is implemented, such as by means of a roller or ball screw drive. In any case, a pivoting movement of the loading arm(s) is then based on a change in length of the linear drive(s).

Gemäß einer bevorzugten Weiterbildung des Fahrzeugkransystems kann der Verladearm oder können die bevorzugt beiden Verladearme jeweils in einen unteren Armabschnitt und in einen oberen Armabschnitt unterteilt sein. Besagte Armabschnitte sind dann über ein Gelenk miteinander verbunden, so dass diese relativ zueinander klappbar sind. Die Klappbarkeit des oder der Verladearme ermöglicht eine noch präzisere Führung eines Anbauteils, da das zusätzliche Gelenk einen weiteren Freiheitsgrad in Bezug auf die Bewegungsfähigkeit des wenigstens einen Verladearms zur Verfügung stellt. Auf diese Weise kann das angekoppelte Anbauteil beispielsweise auch in einer Stellung des wenigstens einen Verladearms durch dessen Knicken um das Gelenk abgesenkt werden, was durch die ansonsten festgelegte, insbesondere kürzeste, Länge und die damit festgelegte Kreisbahn einer Schwenkbewegung des Verladearms ansonsten nicht möglich wäre.According to a preferred development of the vehicle crane system, the loading arm or the preferably two loading arms can each be divided into a lower arm section and an upper arm section. Said arm sections are then connected to one another via a joint so that they can be folded relative to one another. The foldability of the loading arm or arms enables an attachment to be guided even more precisely, since the additional joint provides a further degree of freedom with regard to the mobility of the at least one loading arm. In this way, the attached attachment can also be lowered in a position of the at least one loading arm by bending it around the joint, which would otherwise not be possible due to the otherwise specified, in particular shortest, length and the circular path of a pivoting movement of the loading arm thus specified.

In diesem Zusammenhang wird es als besonders vorteilhaft angesehen, wenn der wenigstens eine Verladearm einen Gelenk-Antrieb besitzt, welcher dann zwischen seinen beiden Armabschnitten gelegen ist. Hinsichtlich der konkreten Ausgestaltung eines solchen Gelenk-Antriebs kann dieser beispielsweise in Form eines längenveränderbaren Linearantriebs ausgebildet sein, um die erforderliche Klappbewegung des Verladearms um sein Gelenk herum durchführen zu können.In this context, it is considered particularly advantageous if the at least one loading arm has an articulated drive, which is then located between its two arm sections. With regard to the specific design of such a joint drive, it can be designed, for example, in the form of a length-adjustable linear drive in order to be able to carry out the necessary folding movement of the loading arm around its joint.

Um ein vorteilhaftes Kräfteverhältnis in Bezug auf den/die Verladearm/e und Schwenk-Antrieb/e zu erhalten, wird es als vorteilhaft angesehen, wenn der, insbesondere jeweilige, Verladearm einen Kopplungsbereich aufweist, welcher dann zur kraftübertragenden Verbindung mit dem Schwenk-Antrieb dient. So kann insbesondere dessen oberer Armabschnitt besagten Kopplungsbereich besitzen und hierüber mit einem ersten Ende des Schwenk-Antriebs kraftübertragend verbunden sein, während ein dem ersten Ende des Schwenk-Antriebs gegenüberliegendes zweites Ende mit der Transportvorrichtung gekoppelt ist. Die Kopplung zwischen Schwenk-Antrieb und Transportvorrichtung kann beispielsweise über ein Lager erfolgen, welches dann beispielsweise auf oder unter der Ladefläche der Transportvorrichtung angeordnet ist.In order to obtain an advantageous balance of power in relation to the loading arm(s) and swivel drive(s), it is considered advantageous if the loading arm, in particular the respective loading arm, has a coupling area which is then used for the force-transmitting connection to the swivel drive . In particular, its upper arm section can have said coupling area and be connected to a first end of the swivel drive in a force-transmitting manner, while a second end opposite the first end of the swivel drive is coupled to the transport device. The coupling between swivel drive and transport device can be done, for example, via a bearing, which is then, for example, on or under the loading area of the Transport device is arranged.

In Bezug auf die Form des, insbesondere jeweiligen, Verladearms kann dessen das freie Tragende aufweisender Endabschnitt bevorzugt zu einer dem Schwenk-Antrieb abgewandten Seite des Verladearms hin abgewinkelt sein.With regard to the shape of the, in particular respective, loading arm, its end section having the free supporting end can preferably be angled towards a side of the loading arm facing away from the swivel drive.

Gemäß einer vorteilhaften Weiterentwicklung ist denkbar, dass der, insbesondere jeweilige, Verladearm längenveränderbar und insofern teleskopierbar ausgebildet ist. Dies meint eine bedarfsweise Veränderbarkeit seiner Länge, wodurch sich beispielsweise eine größere Entfernung zwischen Transportvorrichtung und Fahrzeugkran entsprechend überbrücken lässt. Alternativ oder in Kombination hierzu kann so ein Anbauteil auch weiter auf die Transportvorrichtung aufgenommen werden, sofern erforderlich. Hierzu kann der Verladearm mehrteilig ausgebildet sein, beispielsweise in Form mehrschüssiger Segmente.According to an advantageous further development, it is conceivable that the loading arm, in particular the respective loading arm, is designed such that it can be changed in length and is therefore telescopic. This means that its length can be changed as required, which means that, for example, a larger distance between the transport device and the mobile crane can be bridged accordingly. Alternatively or in combination with this, such an add-on part can also be further accommodated on the transport device, if necessary. For this purpose, the loading arm can be designed in several parts, for example in the form of multi-section segments.

Die mobile Transportvorrichtung kann aktiv oder passiv beweglich ausgestaltet sein. Dies meint, dass die Anbauteil-Transporteinheit beispielsweise selbstangetrieben sein kann, so dass diese quasi automobil, also aus eigenem Antrieb heraus, zwischen ihren Einsatzorten und/oder zum Rangieren verfahrbar ist. Alternativ oder in Ergänzung hierzu kann diese in Bezug auf ihre Verlagerbarkeit selbstverständlich auch nur mitführbar im Sinne eines Anhängers sein. Hierzu kann diese bevorzugt mit einem geeigneten Zugfahrzeug - wie etwa einem Sattelschlepper - gekoppelt werden, welches die dann gezogene und/oder geschobene Anbauteil-Transporteinheit mit sich führt.The mobile transport device can be designed to be movable actively or passively. This means that the attachment transport unit can be self-propelled, for example, so that it can be moved between its locations and/or for maneuvering in a quasi-automotive manner, that is to say of its own accord. As an alternative or in addition to this, it can of course also only be carried along in the sense of a trailer with regard to its displaceability. For this purpose, it can preferably be coupled to a suitable towing vehicle--such as a semi-trailer truck--which carries the attached part transport unit that is then pulled and/or pushed with it.

Gemäß einer bevorzugten Weiterbildung kann der wenigstens eine Verladearm beziehungsweise die Verladeanordnung so ausgestaltet sein, dass diese/r von einem nicht zwingend in unmittelbarer Nähe gelegenen Bereich aus bedienbar ist. Üblicherweise werden die an Fahrzeugen angeordneten Antriebe zur Bewegung solcher Vorrichtungen beispielsweise über eine im und/oder am Fahrzeug selbst angeordnete Bedieneinheit betrieben. Hier sieht die Erfindung die vorteilhafte Möglichkeit zur Bedienung des/der Verladearms/Verladearme von außerhalb vor. Dies meint die Bedienung von außerhalb einer Fahrzeugkabine, die bei einer beispielsweise selbstangetriebenen mobilen Transportvorrichtung Teil der so ausgestalteten Anbauteil-Transporteinheit sein kann. Bei einer bevorzugten Ausgestaltung der Anbauteil-Transporteinheit, bei welcher deren mobile Transportvorrichtung beispielsweise mit einem Zugfahrzeug gekoppelt oder koppelbar ist, kann besagte Fahrzeugkabine entsprechend Teil dieses Zugfahrzeugs sein.According to a preferred development, the at least one loading arm or the loading arrangement can be designed in such a way that it can be operated from an area that is not necessarily in the immediate vicinity. The drives arranged on vehicles for moving such devices are usually operated, for example, via an operating unit arranged in and/or on the vehicle itself. Here the invention provides the advantageous possibility of operating the loading arm(s) from outside. This means operation from outside a vehicle cabin, which in the case of a self-propelled mobile transport device, for example, can be part of the add-on transport unit configured in this way. At a preferred Design of the attachment transport unit, in which the mobile transport device is coupled or can be coupled to a towing vehicle, for example, said vehicle cabin can be part of this towing vehicle.

Besonders bevorzugt kann die Ansteuerung des Verladearms und/oder der Kipp Einrichtung mittels einer drahtlosen oder drahtgebundenen Bedieneinheit erfolgen. Hierdurch ist größtmögliche Flexibilität für eine die Anbauteil-Transporteinheit bedienende Person gegeben. Die Möglichkeit zur räumlichen Entfernung von der Anbauteil-Transporteinheit bietet dabei einen wesentlich besseren Überblick, um trotz der mitunter erheblichen Dimensionen von Fahrzeugkranen und beispielsweise deren Hauptausleger eine überaus präzise Ansteuerung des Verladearms und/oder der Kipp Einrichtung zu gewährleisten. Dies insbesondere im Hinblick auf die Möglichkeit beispielsweise zum Ausgleich von Fluchtungsfehlern und/oder Winkelversätzen während des Umsetzens des Anbauteils über die getrennte Ansteuerung zweier Verladearme.Particularly preferably, the loading arm and/or the tipping device can be controlled by means of a wireless or wired operating unit. This provides the greatest possible flexibility for a person operating the attachment transport unit. The possibility of physical distance from the attachment transport unit offers a much better overview in order to ensure extremely precise control of the loading arm and/or the tilting device despite the sometimes considerable dimensions of mobile cranes and, for example, their main boom. This in particular with regard to the possibility, for example, of compensating for misalignments and/or angular offsets during the transfer of the attachment via the separate control of two loading arms.

Nach einer bevorzugten Weiterbildung kann der Kipp-Antrieb der Kippeinrichtung über sein erstes Ende an der Transportvorrichtung verschwenkbar angeordnet sein. Auf diese Weise kann die Ausrichtung des Kipp-Antriebs der Bewegung des damit koppelbaren Anbauteils bevorzugt spannungsfrei folgen. Weiterhin kann die Kippeinrichtung in vorteilhafter Weise eine Ablage besitzen, auf welcher der Kipp-Antrieb, insbesondere in einer gegenüber einer Horizontalen angehobenen Position, ablegbar ist. Die abgelegte Position des Kipp-Antriebs bildet dabei dessen tiefst mögliche Ausrichtung relativ zur Ladefläche der Transportvorrichtung, wobei die Ablage für eine auch im abgelegten Zustand stets angehobene Ausrichtung des Kipp-Antriebs sorgt, was dessen Kopplung mit einem Anbauteil erleichtert.According to a preferred development, the tilting drive of the tilting device can be pivotably arranged on the transport device via its first end. In this way, the orientation of the tilting drive can follow the movement of the attachment that can be coupled thereto, preferably without tension. Furthermore, the tilting device can advantageously have a shelf on which the tilting drive can be placed, in particular in a raised position relative to a horizontal line. The stowed position of the tilt drive forms its lowest possible orientation relative to the loading surface of the transport device, with the stowage ensuring that the tilt drive is always raised even when it is in the stowed state, which facilitates its coupling to an attachment.

Hinsichtlich der Ausgestaltung der Stützanordnung der Kippeinrichtung sind diverse Formen denkbar, welche eine, bevorzugt horizontale, Abstützbarkeit des Anbauteils an dieser ermöglichen. Bevorzugt kann die Stützanordnung eine erste Erhebung und eine zweite Erhebung besitzen, wobei die beiden Erhebungen unter Ausbildung einer Vertiefung voneinander beabstandet sind. Die durch die beiden Erhebungen begrenzte Vertiefung stellt eine bauliche Aufnahme für das Anbauteil dar, welche eine eindeutige Positionierung des an der Stützanordnung abstützbaren Anbauteils ermöglicht.With regard to the configuration of the support arrangement of the tilting device, various forms are conceivable which enable the add-on part to be supported, preferably horizontally, on this. The support arrangement can preferably have a first elevation and a second elevation, with the two elevations being spaced apart from one another to form a depression. The indentation delimited by the two elevations represents a structural receptacle for the add-on part, which enables the add-on part that can be supported on the support arrangement to be positioned clearly.

Das nunmehr vorgestellte erfindungsgemäße Fahrzeugkransystem ermöglicht die überaus wirtschaftliche und praktikable Durchführung des Transports sowie der Umsetzung eines Anbauteils, insbesondere einer Abspanneinrichtung, für einen Teleskopausleger eines Fahrzeugkrans. Dank der erfindungsgemäßen Ausgestaltung sind keine zusätzlichen Vorrichtungen notwendig, um die für den Transport und die Umsetzung des Anbauteils notwendigen Maßnahmen vollständig durchführen zu können.The vehicle crane system according to the invention that has now been presented enables the extremely economical and practicable implementation of the transport and the repositioning of an add-on part, in particular a guying device, for a telescopic boom of a vehicle crane. Thanks to the configuration according to the invention, no additional devices are necessary in order to be able to fully carry out the measures necessary for transporting and relocating the add-on part.

Weiterhin ist die Erfindung auf ein Verfahren gerichtet, bei dem ein Anbauteil in Form einer Abspanneinrichtung von einer Transportvorrichtung einer Anbauteil-Transporteinheit eines Fahrzeugkransystems auf einen Teleskopausleger eines Fahrzeugkrans umgesetzt wird.

  • Betätigen, insbesondere Verkürzen, des Kipp-Antriebs derart, dass die zumindest bereichsweise an einer Stützanordnung der Kippeinrichtung, insbesondere horizontal, abgestützte Abspanneinrichtung um die Stützanordnung herum gekippt wird, bis ein dem ersten Endabschnitt gegenüberliegender zweiter Endabschnitt der Abspanneinrichtung gegenüber einer Ladefläche der Transportvorrichtung angehoben ist;
  • Annähern des Fahrzeugkrans an die Transportvorrichtung derart, dass der Teleskopausleger zumindest abschnittsweise unterhalb des zweiten Endabschnitts der Abspanneinrichtung angeordnet ist;
  • Betätigen, insbesondere Verlängern, des Kipp-Antriebs derart, dass die Abspanneinrichtung um die Stützanordnung herum zurückgekippt und deren zweiter Endabschnitt in Richtung eines Kopfabschnitts des Teleskopauslegers abgesenkt wird, bis die Abspanneinrichtung an wenigstens einer am Teleskopausleger, insbesondere an dessen Grundkasten, angeordneten Stützrolle abgestützt ist;
  • Betätigen, insbesondere weitergehendes Verlängern, des Kipp-Antriebs derart, dass die Abspanneinrichtung aus der Stützanordnung herausgehoben und die Abspanneinrichtung über eine gleitend und/oder rollend um die Stützrolle des Teleskopauslegers herum erfolgende kombinierte translatorische sowie begrenzt rotatorische erste Aufsetz-Bewegung zumindest abschnittsweise auf dem Teleskopausleger, insbesondere auf dessen Grundkasten, abgelegt wird;
  • Ausrichten zweier an der Transportvorrichtung angeordneter, längenveränderbarer Verladearmen durch paralleles oder voneinander getrennt erfolgendes Betätigen wenigstens eines die Verladearme verschwenkenden Schwenk-Antriebs und deren Längenänderbarkeit derart, bis deren freien Tragenden mit jeweils einer, insbesondere im Bereich des ersten Endabschnitts gelegenen, Koppelstelle der Abspanneinrichtung gekoppelt sind;
  • Entkoppeln des Kipp-Antriebs der Kippeinrichtung von der Abspanneinrichtung;
  • Verschwenken und/oder Verlängern der beiden Verladearme derart, bis die sich dabei über ihren zweiten Endabschnitt auf dem Teleskopausleger gleitend und/oder rollend abstützende Abspanneinrichtung von der Stützrolle des Teleskopauslegers abgehoben ist;
  • Gleichzeitig oder im Anschluss an das Verschwenken und/oder Verlängern der beiden Verladearme erfolgendes Betätigen eines zwischen zwei gelenkig miteinander verbundenen Armabschnitten jedes Verladearms angeordneten Gelenk-Antriebs derart, dass ein oberer Armabschnitt gegenüber einem unteren Armabschnitt des jeweiligen Verladearms abgeklappt wird;
  • paralleles oder voneinander getrennt erfolgendes Betätigen des Schwenk-Antriebs und des Gelenk-Antriebs sowie einer Längenänderbarkeit der Verladearme derart, dass eine kombinierte translatorische sowie begrenzt rotatorische zweite Aufsetz-Bewegung durchgeführt wird, insbesondere bis die Abspanneinrichtung vollständig auf dem Teleskopausleger abgelegt ist;
  • Betätigen, insbesondere Verlängern, eines Wippzylinders des Fahrzeugkrans derart, dass dessen Teleskopausleger gegenüber der Transportvorrichtung angehoben wird, bis die Koppelstellen der Abspanneinrichtung von den freien Tragenden der beiden Verladearme entkoppelt sind;
  • paralleles oder voneinander getrennt erfolgendes Betätigen des Schwenk-Antriebs und des Gelenk-Antriebs derart, bis die beiden Verladearme in Richtung der Ladefläche der Transportvorrichtung zurück verschwenkt sind.
Furthermore, the invention is directed to a method in which an attachment in the form of a guying device is transferred from a transport device of an attachment transport unit of a vehicle crane system to a telescopic boom of a vehicle crane. The procedure includes the following steps:
  • Providing the attachment transport unit with the recorded guying device in the area of the mobile crane;
  • arranging the transport device and the telescopic boom relative to one another in such a way that a longitudinal direction of the guying device is aligned with a longitudinal direction of the telescopic boom;
  • coupling a tilting drive of a tilting device arranged on the loading area of the transport device to a first end section of the guying device;
  • Actuating, in particular shortening, the tilting drive in such a way that the guying device supported at least in some areas on a support arrangement of the tilting device, in particular horizontally, is tilted around the supporting arrangement until a second end section of the guying device, opposite the first end section, is raised relative to a loading surface of the transport device ;
  • Approaching the mobile crane to the transport device in such a way that the telescopic boom is arranged at least in sections below the second end section of the guying device;
  • Actuating, in particular lengthening, the tilting drive in such a way that the guying device is tilted back around the support arrangement and its second end section is lowered in the direction of a head section of the telescopic boom until the guying device is supported on at least one support roller arranged on the telescopic boom, in particular on its base box ;
  • Actuating, in particular further lengthening, the tilting drive in such a way that the guying device is lifted out of the support arrangement and the guying device via a combined translatory and limited rotational first placement movement, which occurs sliding and/or rolling around the support roller of the telescopic boom, at least in sections on the telescopic boom , in particular on its base box, is placed;
  • Alignment of two length-adjustable loading arms arranged on the transport device by parallel or separate actuation of at least one swivel drive that pivots the loading arms and their length changeability in such a way that their free carrying ends are each coupled to a coupling point of the guying device, located in particular in the area of the first end section ;
  • decoupling the tilting drive of the tilting device from the guying device;
  • Pivoting and/or lengthening of the two loading arms in such a way that the guying device, which is supported in a sliding and/or rolling manner via its second end section on the telescopic boom, is lifted off the support roller of the telescopic boom;
  • Simultaneously or following the pivoting and/or lengthening of the two loading arms, actuating a joint drive arranged between two articulated arm sections of each loading arm in such a way that an upper arm section is folded down relative to a lower arm section of the respective loading arm;
  • parallel or separate actuation of the swivel drive and the articulated drive as well as the ability to change the length of the loading arms in such a way that a combined translatory and limited rotary second placement movement is carried out, in particular until the guying device is completely placed on the telescopic boom;
  • Actuating, in particular lengthening, a luffing cylinder of the mobile crane in such a way that its telescopic boom is raised relative to the transport device until the coupling points of the guying device are decoupled from the free ends of the two loading arms;
  • parallel or separate actuation of the swivel drive and the articulated drive in such a way that the two loading arms are swiveled back in the direction of the loading surface of the transport device.

In vorteilhafter Weise kann während oder am Ende der ersten Aufsetz-Bewegung die Abspanneinrichtung über wenigstens einen an dieser angeordneten Vorsprung an der Stützrolle des Teleskopauslegers abgestützt werden.Advantageously, during or at the end of the first placement movement, the guying device can be supported on the support roller of the telescopic boom via at least one projection arranged on it.

Nach einer bevorzugten Weiterbildung des erfindungsgemäßen Verfahrens kann der Kipp-Antrieb der Kippeinrichtung nach seinem Entkoppeln von der Abspanneinrichtung derart betätigt werden, dass dieser verkürzt wird. Auf diese Weise gelangt der Kipp-Antrieb außerhalb des Bewegungsradius des Anbauteils, um etwaigen Kollisionen vorzubeugen. Zudem wird so der Hebelarm des Kipp-Antriebs verkürzt, was dessen Belastung insbesondere während des Verfahrens der Anbauteil-Transporteinheit reduziert.According to a preferred development of the method according to the invention, the tilting drive of the tilting device can be actuated after it has been decoupled from the guying device in such a way that it is shortened. In this way, the tilt drive moves outside the radius of movement of the attachment to prevent any collisions. In addition, the lever arm of the tilting drive is shortened, which reduces its load, in particular during the movement of the attachment transport unit.

Gemäß einer bevorzugten Weiterbildung des erfindungsgemäßen Verfahrens kann die Abspanneinrichtung in ihrem vollständig auf dem Teleskopausleger abgelegten Zustand mit dem Teleskopausleger, insbesondere mit dessen Grundkasten, über wenigstens eine Befestigung, insbesondere Bolzen, verbunden werden, um eine feste lösliche Verbindung zwischen diesen zu erzielen.According to a preferred development of the method according to the invention, the guying device can be connected to the telescopic boom, in particular to its base box, via at least one fastening, in particular bolts, when it is completely placed on the telescopic boom, in order to achieve a firm, detachable connection between them.

Weiterhin ist die Erfindung auf ein Verfahren gerichtet, bei dem ein Anbauteil in Form einer Abspanneinrichtung von einem Teleskopausleger, insbesondere von dessen Grundkasten, eines Fahrzeugkrans auf eine Transportvorrichtung einer Anbauteil-Transporteinheit eines Fahrzeugkransystems umgesetzt wird. Das Verfahren umfasst die folgenden Schritte:

  • Bereitstellen der Anbauteil-Transporteinheit im Bereich des den Teleskopausleger mit der aufsitzenden Abspanneinrichtung aufweisenden Fahrzeugkrans;
  • Bedarfsweises Betätigen, insbesondere Verlängern, eines Wippzylinders des Fahrzeugkrans derart, dass der Teleskopausleger angehoben wird;
  • Anordnen der Transportvorrichtung zumindest abschnittsweise unterhalb des Teleskopauslegers sowie Ausrichten einer Längsrichtung der Transportvorrichtung zu einer Längsrichtung des Teleskopauslegers des Fahrzeugkrans und/oder einer Längsrichtung der Abspanneinrichtung;
  • Ausrichten zweier an der Transportvorrichtung angeordneter, längenveränderbarer Verladearmen durch paralleles oder voneinander getrennt erfolgendes Betätigen wenigstens eines die Verladearme verschwenkenden Schwenk-Antriebs und eines zwischen zwei gelenkig miteinander verbundenen Armabschnitten jedes Verladearms angeordneten Gelenk-Antriebs sowie deren Längenänderbarkeit derart, bis deren freien Tragenden unterhalb jeweils einer, insbesondere im Bereich eines ersten Endabschnitts der Abspanneinrichtung gelegenen, Koppelstelle der Abspanneinrichtung angeordnet sind;
  • Betätigen, insbesondere Verkürzen, des Wippzylinders des Fahrzeugkrans derart, dass der Teleskopausleger zu einer Ladefläche der Transportvorrichtung hin abgesenkt wird, bis an der Abspanneinrichtung angeordnete Koppelstellen mit den freien Tragenden der Verladearme gekoppelt, insbesondere auf diesen abgestützt, sind;
  • Paralleles oder voneinander getrennt erfolgendes Betätigen, insbesondere Verkürzen, des Schwenk-Antriebs und, insbesondere Verlängern, des Gelenk-Antriebs sowie der Längenänderbarkeit, insbesondere Verlängern, der Verladearme derart, dass eine kombinierte translatorische sowie begrenzt rotatorische erste Absetz-Bewegung durchgeführt wird, bis ein der Transportvorrichtung zugewandter erster Endabschnitt der sich über ihren dem ersten Endabschnitt gegenüberliegenden zweiten Endabschnitt auf dem Teleskopausleger gleitend und/oder rollend abstützenden Abspanneinrichtung von dem Teleskopausleger angehoben ist;
  • Paralleles oder voneinander getrennt erfolgendes Betätigen, insbesondere Verkürzen, des Schwenk-Antriebs und/oder Längenverändern, insbesondere Verkürzung, der beiden Verladearme derart, bis die sich dabei über ihren zweiten Endabschnitt auf dem Teleskopausleger, insbesondere dessen Grundkasten, gleitend und/oder rollend abstützende Abspanneinrichtung mit ihrem ersten Endabschnitt zumindest teilweise über einen Kopfabschnitt des Teleskopauslegers überstehend wieder auf dem Teleskopausleger, insbesondere auf dessen Grundkasten, abgelegt ist;
  • Paralleles oder voneinander getrennt erfolgendes Betätigen, insbesondere Verkürzen, des Schwenk-Antriebs und/oder Längenverändern, insbesondere Verkürzung, der beiden Verladearme derart, dass deren freien Tragenden von den Koppelstellen der Abspanneinrichtung entkoppelt werden und in Richtung der Ladefläche der Transportvorrichtung hin abgesenkt sind;

Figur 1 zeigt den Aufbau eines auf einem Untergrund U abgestellten erfindungsgemäßen Fahrzeugkransystems 1, welches einen Fahrzeugkran 2 mit einem sich parallel zu einer Horizontalrichtung X erstreckenden Teleskopausleger 3 sowie ein erfindungsgemäßes Anbauteil-Transportsystem 4 umfasst. Der Teleskopausleger 3 ist in üblicher Weise hydraulisch längenveränderbar und verriegelbar aus einem Grundkasten 3a und hierin geführten Teleskopabschnitten ausgebildet. Über einen Wippzylinder 3b lässt sich der Kopfabschnitt 3c des Teleskopauslegers 3 in hier nicht näher dargestellter Weise anheben und absenken. figure 1 shows the structure of a mobile crane system 1 according to the invention parked on a base U, which comprises a mobile crane 2 with a telescopic boom 3 extending parallel to a horizontal direction X and an attachment transport system 4 according to the invention. The telescopic boom 3 is designed in the usual way to be hydraulically variable in length and lockable from a base box 3a and telescopic sections guided therein. The head section 3c of the telescopic boom 3 can be raised and lowered via a luffing cylinder 3b in a manner that is not shown in detail here.

Figur 2 ist das von dem Fahrzeugkran 2 isoliert dargestellte erfindungsgemäße Anbauteil-Transportsystem 4 aus Figur 1 zu entnehmen. In dieser Darstellung wird deutlich, dass das Anbauteil-Transportsystem 4 eine Anbauteil-Transporteinheit 5 mit einer mobilen Transportvorrichtung 6 aufweist, welche sich ebenfalls parallel zur Horizontalrichtung X erstreckt. Die Transportvorrichtung 6 dient der Aufnahme eines - in Figur 2 bereits auf deren dem Untergrund U abgewandten Ladefläche 6a abgelegten - Anbauteils 7. Die sich sowohl parallel zur Horizontalrichtung X als auch parallel zu einer sich senkrecht zur Blattebene erstreckenden Querrichtung Y ausdehnenden Abmessungen der Ladefläche 6a bieten dabei ausreichend Platz, auf dem sich das Anbauteil 7 abstützen kann. Bei dem Anbauteil 7 handelt es sich vorliegend um eine Abspanneinrichtung, insbesondere einen seitlichen Superlift, welches zur Befestigung an einem Grundkasten 3a des Teleskopauslegers 3 vorgesehen ist. Die Abspanneinrichtung kann in Querrichtung Y hintereinander angeordnete Abspannarme besitzen, die über ein nicht näher erkennbares - im Bereich eines zweiten Endabschnitts 7b der Abspanneinrichtung 7 gelegenes - Verbindungselement derart schwenkbar miteinander verbunden sind, dass besagte Abspannarme unter Einschluss eines Winkels bei Bedarf V förmig zueinander ausgerichtet werden können. Nachfolgend wird besagtes Anbauteil 7 daher als Abspanneinrichtung 7 benannt. figure 2 is the attachment transport system 4 according to the invention shown isolated from the vehicle crane 2 figure 1 refer to. In this representation it is clear that the attachment transport system 4 has an attachment transport unit 5 with a mobile transport device 6 which also extends parallel to the horizontal direction X. The transport device 6 is used to hold a - in figure 2 attachment 7 already placed on its loading area 6a facing away from the ground U. The dimensions of the loading area 6a, which extend both parallel to the horizontal direction X and parallel to a transverse direction Y extending perpendicularly to the plane of the page, offer sufficient space on which the attachment 7 is supported can. In the present case, the add-on part 7 is a guying device, in particular a lateral superlift, which is used for attachment to a base box 3a of the telescopic boom 3 is provided. The guying device can have guying arms arranged one behind the other in the transverse direction Y, which are pivotably connected to one another via a connecting element (located in the region of a second end section 7b of the guying device 7) that is not visible in more detail, such that said guying arms are aligned in a V-shape to one another, including an angle, if required be able. Said attachment 7 is therefore referred to below as the guying device 7 .

Bei der Transportvorrichtung 6 kann es sich beispielsweise um einen - wie vorliegend ersichtlichen - Sattelauflieger, einen Auflieger, einen Tieflader oder einen Anhänger handeln, um nur einige der möglichen Ausgestaltungsformen zu benennen.The transport device 6 can be, for example, a semi-trailer--as can be seen here--a semi-trailer, a low-loader or a trailer, to name just a few of the possible configurations.

Erkennbar ist die Transportvorrichtung 6 als Sattelauflieger ausgebildet. Deren Mobilität geht auf die Kopplung mit einem Zugfahrzeug 8 des Anbauteil-Transportsystems 4 zurück, welches in Form eines Sattelschleppers mit der Transportvorrichtung 6 gekoppelt ist. Das Zugfahrzeug 8 weist eine Fahrzeugkabine 8a auf, von der aus sich das aus Zugfahrzeug 8 und Anbauteil-Transporteinheit 5 bestehende Gespann des Anbauteil-Transportsystems 4, insbesondere in Bezug auf den Transport der Abspanneinrichtung 7, in üblicher Weise steuern lässt.The transport device 6 is recognizable as a semi-trailer. Their mobility is due to the coupling to a towing vehicle 8 of the attachment transport system 4, which is coupled to the transport device 6 in the form of an articulated lorry. The towing vehicle 8 has a vehicle cab 8a from which the combination of the towing vehicle 8 and attachment transport unit 5 of the attachment transport system 4 can be controlled in the usual way, in particular with regard to the transport of the guying device 7 .

Auf der Transportvorrichtung 6 ist eine Kippeinrichtung 9 vorgesehen, welche in Bezug auf die Querrichtung Y ungefähr mittig auf der Ladefläche 6a der Transportvorrichtung 6 angeordnet ist. Die Kippeinrichtung 9 ist dazu ausgebildet, die in Figur 2 bereits auf der Ladefläche 6a der Transportvorrichtung 6 aufgenommene Abspanneinrichtung 7 einseitig anzuheben sowie abzusenken. Hierzu besitzt die Kippeinrichtung 9 einen Kipp-Antrieb 10, welcher in der hier gezeigten Ausführungsform als Linearantrieb ausgebildet ist. Der Kipp-Antrieb 10 ist über sein erstes Ende verschwenkbar auf der Ladefläche 6a der Transportvorrichtung 6 angeordnet, wobei eine Ablage 10a der Kippeinrichtung 9 dazu dient, den in seiner untersten Schwenkstellung auf dieser ablegbaren Kipp-Antrieb 10 in einer gegenüber einer Horizontalen beziehungsweise der Horizontalrichtung X angehobenen Position zu halten. Weiterhin umfasst die Kippeinrichtung 9 eine auf der Ladefläche 6a angeordnete Stützanordnung 11, welche eine erste Erhebung 11a und eine zweite Erhebung 11b aufweist. Beide Erhebungen 11a, 11b sind so parallel zur Horizontalrichtung X voneinander beabstandet, dass diese eine Vertiefung 11c zwischen sich einschließen beziehungsweise ausbilden. An einem dem Kipp-Antrieb 10 zugewandten ersten Endabschnitt 7a sowie an einem dem Kipp-Antrieb 10 abgewandten zweiten Endabschnitt 7b der Abspanneinrichtung 7 besitzt diese je ein Seitenelement in Form von jeweils zwei in Bezug auf die Querrichtung Y voneinander beabstandeten Schenkeln 7c, 7d, die sich parallel zu einer Vertikalrichtung Z senkrecht erstrecken. Die Fußpunkte der am ersten Endabschnitt 7a der Abspanneinrichtung 7 angeordneten Schenkel 7c liegen dabei innerhalb der Vertiefung 11c, so dass die Abspanneinrichtung 7 durch horizontales Abstützen der beiden Schenkel 7c an der zweiten Erhebung 11b über deren der Fußpunkte kippbar ist.A tilting device 9 is provided on the transport device 6 and is arranged approximately centrally on the loading area 6a of the transport device 6 in relation to the transverse direction Y. The tilting device 9 is designed to figure 2 lift and lower already on the loading area 6a of the transport device 6 recorded guying device 7 on one side. For this purpose, the tilting device 9 has a tilting drive 10, which is designed as a linear drive in the embodiment shown here. The tilting drive 10 is arranged via its first end so that it can pivot on the loading surface 6a of the transport device 6, with a shelf 10a of the tilting device 9 serving to support the tilting drive 10, which can be placed on it in its lowest pivoted position, in a direction relative to a horizontal or the horizontal direction X to hold the raised position. Furthermore, the tipping device 9 comprises a support arrangement 11 which is arranged on the loading area 6a and has a first elevation 11a and a second elevation 11b. Both elevations 11a, 11b are spaced apart parallel to the horizontal direction X in such a way that they form a depression 11c include or develop between them. On a first end section 7a facing tilting drive 10 and on a second end section 7b facing away from tilting drive 10, the bracing device 7 has a side element in each case in the form of two legs 7c, 7d spaced apart from one another in relation to the transverse direction Y, which extend perpendicularly parallel to a vertical direction Z. The bases of the legs 7c arranged on the first end section 7a of the guying device 7 lie within the depression 11c, so that the guying device 7 can be tilted by horizontally supporting the two legs 7c on the second elevation 11b via the bases thereof.

Erfindungsgemäß besitzt die Anbauteil-Transporteinheit 5 zudem eine Verladeanordnung 12, welche im Bereich des dem Zugfahrzeug 8 gegenüberliegenden Endes der Transportvorrichtung 6 angeordnet ist. Die Verladeanordnung 10 weist vorliegend zwei Verladearme 13 auf, von denen mit Bezug auf die Darstellung von Figur 2 nur der im Vordergrund stehende Verladearm 13 ersichtlich ist, während der sich vorliegend parallel hierzu erstreckende und in Bezug auf die Querrichtung Y senkrecht zur Blattebene hintere Verladearm 13 durch den im Vordergrund stehenden Verladearm 13 verdeckt ist. Beide Verladearme 13 sind über eine gemeinsame oder jeweils eine eigene Drehachse 14 unterhalb der Ladefläche 6a an der Transportvorrichtung 6 verschwenkbar angelenkt. Die Verladeanordnung 12 dient in Kombination mit der Kippeinrichtung 9 dem Umladen der Abspanneinrichtung 7. Hierzu sind die beiden Verladearme 13 mittels einer aktiven und in gleiche oder entgegengesetzte Richtungen möglichen Rotation um die Drehachse/n 14 herum verschwenkbar.According to the invention, the attachment transport unit 5 also has a loading arrangement 12 which is arranged in the region of the end of the transport device 6 opposite the towing vehicle 8 . The loading arrangement 10 has here two loading arms 13, of which with respect to the representation of FIG figure 2 only the loading arm 13 in the foreground can be seen, while the loading arm 13, which in the present case extends parallel thereto and is at the rear in relation to the transverse direction Y perpendicular to the plane of the drawing, is covered by the loading arm 13 in the foreground. Both loading arms 13 are pivotably articulated on the transport device 6 below the loading surface 6a via a common axis of rotation or a separate axis of rotation 14 each. The loading arrangement 12, in combination with the tilting device 9, serves to reload the guying device 7. For this purpose, the two loading arms 13 can be pivoted about the axis of rotation(s) 14 by means of an active rotation that is possible in the same or opposite directions.

Die freien Tragenden 15 jedes Verladearms 13 sind zur zumindest indirekten zeitlichen Kopplung mit der Abspanneinrichtung 7 vorgesehen, um diese im Rahmen ihrer Umsetzung auf einem Pfad mit einem Bewegungsanteil in Vertikalrichtung y und Horizontalrichtung X zu bewegen. Die aktive Rotation der Verladearme 13 erfolgt dabei über zwei Schwenk-Antriebe 16, von denen aufgrund der Darstellung von Figur 2 ebenfalls nur der im Vordergrund gelegene Schwenk-Antrieb 16 ersichtlich ist. Die beiden Schwenk-Antriebe 16 sind als längenveränderbare Linearantriebe ausgebildet, bei denen es sich bevorzugt um Hydraulikzylinder handeln kann. Ein Einsatz von elektrischen Antrieben ist selbstverständlich ebenfalls denkbar. Jeder dieser beiden Schwenk-Antriebe 16 ist zwischen der Transportvorrichtung 6 und einem der beiden Verladearme 13 eingegliedert. Mit Blick auf den im Vordergrund stehenden und in seiner Form dem verdeckten Verladearm 13 im Wesentlichen identischen Verladearme 13 wird deutlich, dass diese jeweils in einen unteren Armabschnitt 13a und einen oberen Armabschnitt 13b unterteilt sind. Beide Armabschnitte 13a, 13b sind dabei über ein Gelenk 13c miteinander verbunden und relativ zueinander klappbar. Hierzu ist an jedem der beiden Verladearme 13 ein Gelenk-Antrieb 13d vorgesehen, der jeweils endseitig sowohl mit dem unteren Armabschnitt 13a als auch mit dem oberen Armabschnitt 13b gelenkig verbunden ist. Erkennbar ist der Gelenk-Antrieb 13d als längenveränderbarer Linearantrieb ausgebildet, bei dem es sich bevorzugt um jeweils einen Hydraulikzylinder handeln kann. Ein Einsatz von elektrischen Antrieben ist selbstverständlich ebenfalls denkbar.The cantilevers 15 of each loading arm 13 are provided for at least indirect temporal coupling with the guying device 7 in order to move them along a path with a movement component in the vertical direction y and horizontal direction X as part of their conversion. The active rotation of the loading arms 13 takes place via two pivot drives 16, of which due to the representation of figure 2 also only the swivel drive 16 in the foreground can be seen. The two swivel drives 16 are designed as length-adjustable linear drives, which can preferably be hydraulic cylinders. The use of electric drives is of course also conceivable. Any of these two Pivoting drives 16 are integrated between the transport device 6 and one of the two loading arms 13 . Looking at the loading arms 13 in the foreground, which are essentially identical in shape to the covered loading arm 13, it becomes clear that these are each divided into a lower arm section 13a and an upper arm section 13b. Both arm sections 13a, 13b are connected to one another via a joint 13c and can be folded relative to one another. For this purpose, an articulated drive 13d is provided on each of the two loading arms 13, which is articulated at the end both to the lower arm section 13a and to the upper arm section 13b. As can be seen, the articulated drive 13d is designed as a length-adjustable linear drive, which can preferably be a hydraulic cylinder in each case. The use of electric drives is of course also conceivable.

Jeder obere Armabschnitt 13b der beiden Verladearme 13 weist einen Kopplungsbereich 13e auf, welcher jeweils auf einer den Gelenk-Antrieben 13d abgewandten Seite des zugehörigen Verladearms 13 angeordnet ist. Demgegenüber weist die Transportvorrichtung 6 zwei unterhalb ihrer Ladefläche 6a angeordnete Lager 6b auf, die jeweils im Wesentlichen in Ebene eines der beiden Schwenk-Antriebe 16 gelegen sind. Die beiden Schwenk-Antriebe 16 sind dabei so zwischen der Transportvorrichtung 6 und dem jeweils zugehörigen Verladearm 13 eingegliedert, dass diese über ein erstes Ende mit dem Kopplungsbereich 13e eines Verladearms 13 kraftübertragend verbunden sind, wohingegen deren dem ersten Ende gegenüberliegenden zweiten Enden jeweils mit einem der Lager 6b gekoppelt sind. In dieser Anordnung sind die freien Tragenden 15 jedes Verladearms 13 zu einer dem zugehörigen Linearantrieb 16 abgewandten Seite hin abgewinkelt.Each upper arm section 13b of the two loading arms 13 has a coupling region 13e, which is arranged on a side of the associated loading arm 13 that faces away from the articulated drives 13d. In contrast, the transport device 6 has two bearings 6b which are arranged below its loading surface 6a and which are each located essentially in the plane of one of the two swivel drives 16 . The two swivel drives 16 are integrated between the transport device 6 and the associated loading arm 13 in such a way that they are connected via a first end to the coupling region 13e of a loading arm 13 in a force-transmitting manner, whereas their second ends, which are opposite the first end, are each connected to one of the Bearing 6b are coupled. In this arrangement, the cantilevers 15 of each loading arm 13 are angled toward a side remote from the associated linear drive 16 .

Die nachfolgend näher beschriebenen Figuren 3 bis 17 zeigen aufeinanderfolgende Maßnahmen, um die Abspanneinrichtung 7 zwischen der Transportvorrichtung 6 der Anbauteil-Transporteinheit 5 und dem Teleskopausleger 3 des Fahrzeugkrans 2 umzusetzen:
Figur 3 verdeutlicht das im Bereich des hier aus Übersichtsgründen nicht gezeigten Fahrzeugkrans 2 bereitgestellte Anbauteil-Transportsystem 4 aus Zugfahrzeug 8 und Anbauteil-Transporteinheit 5 mit der auf deren Transportvorrichtung 6 aufgenommenen Abspanneinrichtung 7. In hier nicht näher gezeigter Weise sind die Transportvorrichtung 6 und der Teleskopausleger 3 des Fahrzeugkrans 2 dabei so relativ zueinander arrangiert, dass die Längsrichtung der Abspanneinrichtung zur Längsrichtung des Teleskopauslegers 3 hin ausgerichtet ist. Um den zweiten Endabschnitt 7b der hier noch vollständig auf der Ladefläche 6a der Transportvorrichtung 6 abgelegten Abspanneinrichtung 7 anheben zu können, wurde ein zweites (freies) Ende 10b des Kipp-Antriebs 10 in geeigneter Weise mit dem ersten Endabschnitt 7a der Abspanneinrichtung 7 gekoppelt. Hierzu wurde der Kipp-Antrieb 10 aus seiner auf der Ablage 10a abgelegten Position heraus mittels einer manuellen Aufricht-Bewegung A1 angehoben, wobei durch eine den Kipp-Antrieb 10 verlängernde Linearbewegung M1 dessen zweites Ende 10b zu einem Verbindungsbereich 7e des ersten Endabschnitts 7a der Abspanneinrichtung 7 hin verlagert und mit diesem verbunden wurde; beispielsweise mittels eines Bolzens.Those described in more detail below Figures 3 to 17 show successive measures to implement the guying device 7 between the transport device 6 of the attachment transport unit 5 and the telescopic boom 3 of the mobile crane 2:
figure 3 illustrates the attachments transport system 4 provided in the area of the vehicle crane 2, not shown here for reasons of clarity, consisting of towing vehicle 8 and attachments transport unit 5 with the guying device 7 accommodated on the transport device 6. In a manner not shown in detail here, the The transport device 6 and the telescopic boom 3 of the mobile crane 2 are arranged relative to one another in such a way that the longitudinal direction of the guying device is aligned with the longitudinal direction of the telescopic boom 3 . In order to be able to lift the second end section 7b of the guying device 7, which is still completely placed on the loading area 6a of the transport device 6, a second (free) end 10b of the tilting drive 10 was coupled in a suitable manner to the first end section 7a of the guying device 7. For this purpose, the tilting drive 10 was lifted out of its position on the shelf 10a by means of a manual uprighting movement A1, with a linear movement M1 lengthening the tilting drive 10 bringing its second end 10b to a connecting area 7e of the first end section 7a of the guying device 7 has been relocated to and connected to; for example by means of a bolt.

Figur 4 ist der angehobene Zustand des zweiten Endabschnitts 7b der Abspanneinrichtung 7 zu entnehmen. Hierzu wurde der mit der Abspanneinrichtung 7 gekoppelte Kipp-Antrieb 10 erneut betätigt, wobei durch eine den Kipp-Antrieb 10 verkürzende Linearbewegung M1 der erste Endabschnitt 7a der Abspanneinrichtung 7 an den Kipp-Antrieb 10 herangezogen wurde. Durch die dabei aktivierte horizontale Abstützung der Abspanneinrichtung 7 über den Fußpunkt ihrer Schenkel 7c an der zweiten Erhebung 11b der Stützanordnung 11 wurde die Abspanneinrichtung 7 über eine Kippbewegung P derart um die Stützanordnung 11 herum gekippt, dass der zweite Endabschnitt 7b der Abspanneinrichtung 7 gegenüber der Ladefläche 6a der Transportvorrichtung 6 nunmehr angehoben ist. figure 4 the raised state of the second end section 7b of the guying device 7 can be seen. For this purpose, the tilting drive 10 coupled to the guying device 7 was actuated again, with the first end section 7a of the guying device 7 being drawn towards the tilting drive 10 by a linear movement M1 shortening the tilting drive 10 . The activated horizontal support of the guying device 7 via the base of its legs 7c on the second elevation 11b of the support arrangement 11 caused the guying device 7 to be tilted around the supporting arrangement 11 via a tilting movement P in such a way that the second end section 7b of the guying device 7 was opposite the loading area 6a of the transport device 6 is now raised.

Figur 5 ist eine Übersicht über das Fahrzeugkransystem 1 zu entnehmen, wobei sich die Abspanneinrichtung 7 weiterhin im angehobenen Zustand ihres zweiten Endabschnitts 7b befindet. Im nächsten Schritt wird nun der Fahrzeugkran 2 mittels einer Verfahrbewegung V an die Transportvorrichtung 6 des Anbauteil-Transportsystems 4 angenähert. Selbstverständlich kann besagte Verfahrbewegung V auch richtungsverkehrt erfolgen, wodurch das Anbauteil-Transportsystem 4 auch an den Fahrzeugkran 2 angenähert werden kann. figure 5 FIG. 1 shows an overview of the vehicle crane system 1, with the guying device 7 still being in the raised state of its second end section 7b. In the next step, the mobile crane 2 is brought closer to the transport device 6 of the attachment transport system 4 by means of a displacement movement V. Of course, said displacement movement V can also take place in the wrong direction, as a result of which the attachment transport system 4 can also be brought closer to the mobile crane 2 .

Figur 6 zeigt den für die weiteren Schritte erforderlichen angenäherten Zustand des hier nur mit einem Abschnitt seines Teleskopauslegers 3 erkennbaren Fahrzeugkrans 2 an die Transportvorrichtung 6 des Anbauteil-Transportsystems 4. Die vorangegangene Verfahrbewegung V des Fahrzeugkrans 2 erfolgte dabei nur so weit, bis sich der Teleskopausleger 3 abschnittsweise unterhalb des zweiten Endabschnitts 7b der Abspanneinrichtung 7 befindet. figure 6 shows the approximate state required for the further steps of the vehicle crane 2, which can only be seen here with a section of its telescopic boom 3, on the transport device 6 of the attachment transport system 4 The previous movement V of the mobile crane 2 only took place until the telescopic boom 3 is located below the second end section 7b of the guying device 7 in sections.

Figur 7 verdeutlicht das anschließende Absenken des zweiten Endabschnitts 7b der Abspanneinrichtung 7 in Richtung des Teleskopauslegers 3. Hierzu wurde erneut der Kipp-Antrieb 10 betätigt, woraufhin die aus der den Kipp-Antrieb 10 verlängernden Linearbewegung M1 her resultierende Kippbewegung P der Abspanneinrichtung 7 um die Stützanordnung 11 herum erfolgte. Im Ergebnis wurde der zweite Endabschnitt 7b der Abspanneinrichtung 7 so weit in Richtung des Kopfabschnitts 3c des Teleskopauslegers 3 abgesenkt, bis sich die Abspanneinrichtung 7 auf einer am freien Ende des Grundkastens 3a angeordnete Stützrolle 3d abgestützt hat. figure 7 illustrates the subsequent lowering of the second end section 7b of the guying device 7 in the direction of the telescopic boom 3. To do this, the tilting drive 10 was actuated again, whereupon the tilting movement P of the guying device 7 around the support arrangement 11 resulting from the linear movement M1 lengthening the tilting drive 10 around. As a result, the second end section 7b of the guying device 7 was lowered in the direction of the head section 3c of the telescopic boom 3 until the guying device 7 was supported on a support roller 3d arranged at the free end of the base box 3a.

Figur 8 ist die zumindest abschnittsweise Ablage der Abspanneinrichtung 7 auf dem Grundkasten 3a des Teleskopauslegers 3 zu entnehmen. Dieser Zustand wurde erreicht, indem durch eine den Kipp-Antrieb 10 weiter verlängernden Linearbewegung M1 die Abspanneinrichtung 7 zunächst aus der Stützanordnung 11 herausgehoben wurde. Aufgrund der sich zwangsläufig einstellenden Kinematik erzeugte die weitergehende Verlängerung des Kipp-Antriebs 10 eine gleitend und/oder rollend um die Stützrolle 3d des Teleskopauslegers 3 herum erfolgende kombinierte translatorische sowie begrenzt rotatorische erste Aufsetz-Bewegung AUF1. Um dabei das Absenken des zweiten Endabschnitts 7b einzuleiten und um die Weite in Bezug auf das Aufsitzen der Abspanneinrichtung 7 auf dem Grundkasten 3a des Teleskopauslegers 3 zu begrenzen, weist die Abspanneinrichtung 7 wenigstens einen Vorsprung 7g auf, an den sich im Verlauf der ersten Aufsetz-Bewegung AUF1 die Stützrolle 3d annähert und letztlich abstützt. Auf diese Weise ist die Verlagerung der Abspanneinrichtung 7 parallel zur Horizontalrichtung X begrenzt und die Kippbewegung P bereits baulich eingeleitet. figure 8 the at least partial placement of the guying device 7 on the base box 3a of the telescopic boom 3 can be seen. This state was achieved in that the guying device 7 was first lifted out of the support arrangement 11 by means of a linear movement M1 further lengthening the tilting drive 10 . Due to the inevitable kinematics, the further lengthening of the tilting drive 10 produced a combined translatory and limited rotary first touchdown movement AUF1 sliding and/or rolling around the support roller 3d of the telescopic boom 3 . In order to initiate the lowering of the second end section 7b and to limit the width in relation to the seating of the guying device 7 on the base box 3a of the telescopic boom 3, the guying device 7 has at least one projection 7g, to which in the course of the first placement Movement Auf1 the support roller 3d approaches and ultimately supports. In this way, the displacement of the guying device 7 parallel to the horizontal direction X is limited and the tilting movement P is already structurally initiated.

Figur 9 zeigt das Ergebnis einer anschließenden Schwenkbewegung S der beiden Verladearme 13 um deren Drehachse/n 14 herum in Kombination mit deren Längenveränderung durch eine Teleskopierbewegung T, wodurch deren freien Tragenden 15 nun jeweils mit einer im Bereich des ersten Endabschnitts 7a der Abspanneinrichtung 7 gelegenen Koppelstelle 7f gekoppelt ist. Wie beispielsweise in Figur 8 erkennbar, weisen besagte Koppelstellen 7f eine fast halbkreisförmige Vertiefung auf, in welche die freien Tragenden 15 der Verladearme 13 derart gelenkartig eingreifen können, dass auch im gekoppelten Zustand eine quasi drehende Relativbewegung zwischen den freien Tragenden 15 und der Abspanneinrichtung 7 ermöglicht ist. Die Schwenkbewegung S der beiden Verladearme 13 basiert dabei auf einer die beiden Schwenk-Antriebe 16 verlängernden Linearbewegung M2. figure 9 shows the result of a subsequent pivoting movement S of the two loading arms 13 around their axis of rotation(s) 14 in combination with their change in length due to a telescoping movement T, as a result of which their free supporting ends 15 are now each coupled to a coupling point 7f located in the area of the first end section 7a of the guying device 7 is. As for example in figure 8 recognizable, said coupling points 7f have an almost semicircular Deepening, in which the cantilevers 15 of the loading arms 13 can intervene like a joint in such a way that a quasi-rotating relative movement between the cantilevers 15 and the guying device 7 is also made possible in the coupled state. The pivoting movement S of the two loading arms 13 is based on a linear movement M2 that lengthens the two pivoting drives 16 .

Figur 10 ist zu entnehmen, dass in einem nächsten Schritt der im Weiteren nicht mehr benötigte Kipp-Antrieb 10 von dem Verbindungsbereich 7e des ersten Endabschnitts 7a der Abspanneinrichtung 7 entkoppelt und auf seiner Ablage 10a abgelegt wurde. Zuvor oder parallel hierzu wurde der Kipp-Antrieb 10 mittels einer Linearbewegung M1 wieder verkürzt. figure 10 it can be seen that in a next step the tilting drive 10 no longer required was decoupled from the connection area 7e of the first end section 7a of the guying device 7 and placed on its shelf 10a. Beforehand or parallel to this, the tilting drive 10 was shortened again by means of a linear movement M1.

Figur 11 verdeutlicht das anschließende Abheben der Abspanneinrichtung 7 von der Stützrolle 3d des Teleskopauslegers 3, indem die Verladearme 13 auf Basis einer deren Schwenk-Antriebe 16 weiter verlängernden Linearbewegung M2 in eine weitergehende Schwenkbewegung S versetzt wurde. Diese Bewegung kann durch eine weitergehende, die Verladearme 13 verlängernde Teleskopierbewegung T unterstützt werden. Aufgrund der sich zwangsläufig einstellenden Kinematik stützt sich die Abspanneinrichtung 7 dabei einerseits auf den freien Tragenden 15 der Verladearme 13 und andererseits über ihren zweiten Endabschnitt 7b auf dem Teleskopauslegers 3 ab, wobei letztere gleitend und/oder rollend auf dessen Grundkasten 3a erfolgt. Hierzu weist die Abspanneinrichtung 7 wenigstens einen an ihrem zweiten Endabschnitt 7b gelegenen und hier nicht näher ersichtlichen Rollen- und/oder Gleitkörper 7h auf, über den der zweite Endabschnitt 7b der Abspanneinrichtung 7 parallel zur Längsrichtung des Teleskopauslegers 3 auf dessen Grundkasten 3a verlagerbar ist. Besagter Rollen- und/oder Gleitkörper 7h kann bei einer Ausgestaltung der Abspanneinrichtung 7 als Superlift dann beispielsweise an dessen zwischen seinen Abspannarmen gelegenem Verbindungselement angeordnet sein. figure 11 clarifies the subsequent lifting of the guying device 7 from the support roller 3d of the telescopic boom 3, in that the loading arms 13 were set in a further pivoting movement S on the basis of a linear movement M2 that further lengthens their pivoting drives 16. This movement can be supported by a further telescoping movement T that lengthens the loading arms 13 . Due to the inevitable kinematics, the guying device 7 is supported on the one hand on the free supports 15 of the loading arms 13 and on the other hand via its second end section 7b on the telescopic boom 3, with the latter sliding and/or rolling on its base box 3a. For this purpose, the guying device 7 has at least one roller and/or sliding body 7h located on its second end section 7b and not shown here, via which the second end section 7b of the guying device 7 can be displaced parallel to the longitudinal direction of the telescopic boom 3 on its base box 3a. If the guying device 7 is designed as a superlift, said roller and/or sliding body 7h can then be arranged, for example, on its connecting element located between its guying arms.

Figur 12 ist zu entnehmen, dass mit zunehmender Schwenkbewegung S und/oder Teleskopierbewegung T der beiden Verladearme 13 der zweite Endabschnitt 7b der Abspanneinrichtung 7 weiter vom Kopfabschnitt 3c des Teleskopauslegers 3 weg auf dessen Grundkasten 3a verlagert wird. figure 12 it can be seen that with increasing pivoting movement S and/or telescoping movement T of the two loading arms 13, the second end section 7b of the guying device 7 is shifted further away from the head section 3c of the telescopic boom 3 onto its base box 3a.

Figur 13 zeigt einen weiteren Schritt, bei dem der zwischen den zwei gelenkig miteinander verbundenen Armabschnitten 13a, 13b jedes Verladearms 13 angeordnete Gelenk-Antrieb 13d derart betätigt wird, dass infolge einer diesen verkürzenden Linearbewegung M3 die beiden Armabschnitte 13a, 13b über eine Klappbewegung K gegeneinander verschwenkt werden. Mit anderen Worten wird hierbei der jeweilige obere Armabschnitt 13b gegenüber dem zugehörigen unteren Armabschnitt 13a begrenzt abgeklappt. figure 13 shows a further step in which the joint drive 13d arranged between the two articulated arm sections 13a, 13b of each loading arm 13 is actuated in such a way that as a result of a linear movement M3 shortening it, the two arm sections 13a, 13b are pivoted towards one another via a folding movement K . In other words, the respective upper arm section 13b is folded down to a limited extent in relation to the associated lower arm section 13a.

Figur 14 verdeutlicht eine zweite Aufsetz-Bewegung AUF2, bei der durch parallele oder voneinander getrennte Betätigung der Schwenk-Antriebe 13d und des Gelenk-Antriebs 16 sowie der Längenänderbarkeit der Verladearme 13 eine kombinierte translatorische sowie begrenzt rotatorische Abfolge aus Schwenkbewegung S, Klappbewegung K und die beiden Verladearme 13 verkürzender Teleskopierbewegung T durchgeführt wird, bis die Abspanneinrichtung 7 weitestgehend in Richtung Grundkasten 3a des Teleskopauslegers 3 abgesenkt ist. figure 14 illustrates a second placement movement UP2, in which, through parallel or separate actuation of the swivel drives 13d and the articulated drive 16 as well as the ability to change the length of the loading arms 13, a combined translational and limited rotary sequence of swiveling movement S, folding movement K and the two loading arms 13 shortening telescoping movement T is carried out until the guying device 7 is lowered as far as possible in the direction of the base box 3a of the telescopic boom 3 .

Figur 15 ist der vollständig auf dem Grundkasten 3a des Teleskopauslegers 3 abgelegte Zustand der Abspanneinrichtung 7 zu entnehmen. Hierzu wurde der Wippzylinder 3b des Fahrzeugkrans 2 durch eine Linearbewegung M4 verlängert, wodurch der Teleskopausleger 3 aus seiner zuvor noch parallel zur Horizontalrichtung X verlaufenden Ausrichtung über eine entsprechende Wippbewegung W gegenüber dem Untergrund U derart angehoben wurde, dass dessen Grundkasten 3a nunmehr vollständig unter die Abspanneinrichtung 7 verlagert wurde. figure 15 the state of the guying device 7 that is completely laid down on the base box 3a of the telescopic boom 3 can be seen. For this purpose, the luffing cylinder 3b of the mobile crane 2 was lengthened by a linear movement M4, as a result of which the telescopic boom 3 was raised from its alignment, which previously ran parallel to the horizontal direction X, via a corresponding luffing movement W in relation to the substructure U in such a way that its base box 3a was now completely under the guying device 7 was relocated.

Figur 16 zeigt, dass die Koppelstellen 7f der Abspanneinrichtung 7 aufgrund der bereits in Figur 15 beschriebenen oder einer weitergehenden Wippbewegung W des Teleskopauslegers 3 von den freien Tragenden 15 der beiden Verladearme 13 abgehoben und insofern von diesen entkoppelt wurden. figure 16 shows that the coupling points 7f of the guying device 7 due to the already in figure 15 described or a further rocking movement W of the telescopic boom 3 were lifted from the free supporting ends 15 of the two loading arms 13 and insofar decoupled from them.

Figur 17 ist die Situation kurz vor dem Wegbewegen des Fahrzeugkrans 2 von dem Anbauteil-Transportsystem 4 oder umgekehrt mittels einer Verfahrbewegung V zu entnehmen. Zu diesem Zeitpunkt ist die Abspanneinrichtung 7 nunmehr vollständig umgesetzt und wurde in nicht näher gezeigter Weise mit dem Grundkasten 3a des Teleskopauslegers 3 verbunden, beispielsweise durch Verbolzen. Zuvor oder im Anschluss werden die Schwenk-Antriebe 16 und die Gelenk-Antriebe 13d derart betätigt, bis die beiden Verladearme 13 über eine entsprechende Kippbewegung K und Schwenkbewegung S wieder zurück in Richtung der Ladefläche 6a der Transportvorrichtung 6 verschwenkt sind. figure 17 the situation can be seen shortly before the mobile crane 2 is moved away from the attachment transport system 4 or vice versa by means of a displacement movement V. At this point in time, the guying device 7 has now been completely implemented and was connected to the base box 3a of the telescopic boom 3 in a manner not shown in detail, for example by bolting. Before or in The swivel drives 16 and the articulated drives 13d are then actuated in such a way that the two loading arms 13 are swiveled back in the direction of the loading surface 6a of the transport device 6 via a corresponding tilting movement K and swiveling movement S.

Das Umsetzen der Abspanneinrichtung 7 von einem Teleskopausleger 3 des Fahrzeugkrans 2 zurück auf die Transportvorrichtung 6 der Anbauteil-Transporteinheit 4 erfolgt in umgekehrter Weise, wie im übrigen in der Beschreibung bereits dargelegt und anhand der nunmehr erläuterten Figuren 1 bis 17 logisch nachvollziehbar. Hierzu werden unter anderem Bewegungen im Sinne einer ersten Absetz-Bewegung AB1 und einer zweiten Absetz-Bewegung AB2 durchgeführt. Von denen entspricht die erste Absetz-Bewegung AB1 einer der zweiten Aufsetz-Bewegung AUF2 in entgegengesetzter Richtung erfolgenden Bewegung, während die zweite Absetz-Bewegung AB2 eine der ersten Aufsetz-Bewegung AUF1 entgegengesetzte Bewegung ist.Relocating the guying device 7 from a telescopic boom 3 of the mobile crane 2 back to the transport device 6 of the attachment transport unit 4 takes place in the reverse manner, as otherwise already explained in the description and with reference to the ones now explained Figures 1 to 17 logically understandable. For this purpose, among other things, movements in the sense of a first lowering movement AB1 and a second lowering movement AB2 are carried out. Of these, the first lowering movement AB1 corresponds to a movement occurring in the opposite direction to the second lowering movement AUF2, while the second lowering movement AB2 is a movement opposite to the first lowering movement AUF1.

    - simultaneously or separately from one another, actuating, in particular shortening, the pivoting drive (16) and, in particular lengthening, the articulated drive (13d) and changing the length, in particular lengthening, the loading arms (13) such that a combined translational and limited rotational first setting-down movement (AB1) is carried out until a first end portion (7a), facing the transport apparatus (6), of the guying device (7) which is slidably and/or rollably supported on the telescopic jib (3) via the second end portion (7b), opposite the first end portion (7a), of said guying device is raised from the telescopic jib (3);
    - simultaneously or separately from one another, actuating, in particular shortening, the pivoting drive (16) and/or changing the length, in particular shortening, the two loading arms (13) until the guying device (7) which is slidably and/or rollably supported via the second end portion (7b) thereof on the telescopic jib (3), in particular the base box (3a) thereof, is placed back on the telescopic jib (3), in particular on the base box (3a) thereof, so as to have the first end portion (7a) of said guying device projecting at least partially beyond a head portion (3c) of the telescopic jib (3);
    - simultaneously or separately from one another, actuating, in particular shortening, the pivoting drive (16) and/or changing the length, in particular shortening, the two loading arms (13) such that the free load-bearing ends (15) thereof are decoupled from the coupling points (7f) of the guying device (7) and lowered in the direction of the loading surface (6a) of the transport apparatus (6);
    - coupling a tilt drive (10) of a tilting device (9) arranged on the loading surface (6a) of the transport apparatus (6) to the at least partially projecting first end portion (7a) of the guying device (7);
    - actuating, in particular shortening, the tilt drive (10) such that the guying device (7) is tilted by means of a combined translational and limited rotational second setting-down movement (AB2) around at least one support roller (3d) arranged on the telescopic jib (3), in particular on the base box (3a) thereof, until the second end portion (7b) of the guying device (7) is raised from the telescopic jib (3), in particular the base box (3a) thereof, and the first end portion (7a) of the guying device (7) which is slidably and/or rollably supported on the support roller (3d) is supported at least in regions on a support arrangement (11) of the tilting device (9);
    - actuating, in particular further shortening, the tilt drive (10) such that the guying device (7) is tilted around the support arrangement (11) until the guying device (7) is completely raised from the telescopic jib (3), in particular from the base box (3a) thereof;
    - removing the vehicle crane (2) from the attachment transport unit (5) until the telescopic jib (3) is moved out of a region located between the tilted guying device (7) and the loading surface (6a) of the transport apparatus (6);
    - actuating, in particular lengthening, the tilt drive (10) such that the guying device (7) is tilted back around the support arrangement (11) and lowered in the direction of the loading surface (6a) of the transport apparatus (6) until the second end portion (7b) of the guying device (7) is at least partially supported on the loading surface (6a) of the transport apparatus (6);
    - decoupling the tilt drive (10) of the tilting device (9) from the guying device (7).
  13. Method according to claim 12, characterized in that, during or at the end of the second setting-down movement (AB2), the guying device (7) is supported on the support roller (3d) of the telescopic jib (3) via at least one projection (7g) arranged on said guying device.
  14. Method according to either claim 12 or claim 13, characterized by actuating the tilt drive (10) of the tilting device (9) such that said tilt drive is lengthened before it is coupled to the first end portion (7a) of the guying device (7) and/or is shortened after it is decoupled from the guying device (7).
  15. Method according to any of claims 12 to 14, characterized in that each fastening, in particular bolting, that connects the guying device (7) to the telescopic jib (3) is released before the guying device (7) is raised from the telescopic jib (3).
