Description

Die vorliegende Erfindung betrifft einen Fahrzeugkran mit einer am Oberwagen angeordneten Winde, insbesondere einer Hubwinde. Ein solcher Fahrzeugkran umfasst dabei üblicherweise den drehbar auf einem Unterwagen angeordneten Oberwagen, wobei die Winde am Drehbühnenrahmen des Oberwagens angeordnet ist. Weiterhin ist am Oberwagen üblicherweise ein Ausleger angeordnet, welcher über Hydrozylinder aufgewippt werden kann. Die Hubwinde dient dabei beim Anheben einer Last dem Betätigen des Hubseils. Ebenso können hierzu mehrere Hubwinden vorgesehen sein.The present invention relates to a vehicle crane with a winch arranged on the superstructure, in particular a hoist winch. Such a vehicle crane usually comprises the upper carriage rotatably mounted on a lower carriage, wherein the winch is arranged on the revolving platform frame of the upper carriage. Furthermore, a boom is usually arranged on the superstructure, which can be flipped over hydraulic cylinders. The hoist winch serves to lift the hoist when lifting a load. Likewise, several hoisting winches can be provided for this purpose.

Im Arbeitszustand kann dabei der Ausleger des Fahrzeugkrans auch stark abgewippt werden. In dieser flachen Stellung sind sämtliche Hubseile von den Hubwinden zur Spitze des Auslegers zu führen. Hieraus ergibt sich, dass die hintere Winde höher zu positionieren ist. Hierdurch kann jedoch die von der STVZO zugelassene Höhe beim Transport überschritten werden.In working condition while the boom of the vehicle crane can also be heavily tapped off. In this flat position all hoist ropes are to be guided by the hoist winches to the top of the jib. It follows that the rear winch is to be positioned higher. However, this means that the height permitted by the STVZO can be exceeded during transport.

Weiterhin ergibt sich bei vielen bekannten Fahrzeugkränen das Problem, dass die Einsatzbereitschaft des Kranes auf der Baustelle nur mittels eines Hilfskrans herzustellen ist, da An- und Umbauten am Fahrzeugkran auf der Baustelle notwendig sind, um die Transportvorschriften hinsichtlich maximal zulässiger Höhe und Achslasten sicherzustellen.Furthermore, in many known vehicle cranes there is the problem that the operational readiness of the crane on the construction site is only to be established by means of an auxiliary crane, since attachments and conversions on the vehicle crane are necessary on the construction site to ensure the maximum permissible height and axle loads transport regulations.

DE 199 64 356 B4 betrifft einen Kran gemäß dem Oberbegriff des Anspruchs 1. Aufgabe der vorliegenden Erfindung ist es daher, einen Fahrzeugkran zur Verfügung zu stellen, welcher die Transportvorschriften hinsichtlich maximal zulässiger Höhe und Achslasten einhält. Weiterhin ist es Aufgabe der vorliegenden Erfindung, einen Fahrzeugkran bereitzustellen, der auf vielen Baustellen ohne Hilfskran selbständig die Einsatzbereitschaft herstellen kann. DE 199 64 356 B4 relates to a crane according to the preamble of claim 1. The object of the present invention is therefore to provide a vehicle crane, which complies with the transport regulations in terms of maximum height and axle loads. Furthermore, it is an object of the present invention to provide a vehicle crane, which can independently establish operational readiness on many construction sites without auxiliary crane.

Erfindungsgemäß wird diese Aufgabe von einem Fahrzeugkran gemäß Anspruch 1 gelöst. Erfindungsgemäß weist der Fahrzeugkran hierfür Mittel zum Anheben und/oder Absenken der Winde auf. Hierdurch kann der erfindungsgemäße Fahrzeugkran selbständig die Einsatzbereitschaft auf der Baustelle herstellen, ohne dass die Winde während dem Transport in ihrer Betriebsstellung verbleiben muss.According to the invention, this object is achieved by a vehicle crane according to claim 1. According to the invention, the vehicle crane for this purpose has means for lifting and / or lowering the winch. As a result, the vehicle crane according to the invention can independently establish readiness for use on the construction site without the winch having to remain in its operating position during transport.

Vorteilhafterweise kann die Winde dabei lösbar mit dem Fahrzeugkran verbindbar sein, insbesondere um zum Transport durch die Mittel zum Anheben und/oder Absenken der Winde abgenommen und danach wieder montiert werden zu können. So kann die Winde durch die Mittel zum Anheben und/oder Absenken der Winde vor dem Transport abgebaut werden, so dass sich die Höhe und das Gewicht des erfindungsgemäßen Fahrzeugkrans während des Transports entsprechend verringert. Auf der Baustelle wird die Winde dann wieder montiert. Beides kann dabei durch die erfindungsgemäßen Mittel zum Anheben und/oder Absenken der Winde ohne einen Hilfskran erfolgen.Advantageously, the winch can be releasably connected to the vehicle crane, in particular to be removed for transport by the means for raising and / or lowering the winch and then to be able to be re-assembled. Thus, the winch can be reduced by the means for raising and / or lowering the winch before transport, so that the height and weight of the vehicle crane according to the invention during transport reduced accordingly. At the construction site, the winch is then reinstalled. Both can be done by the inventive means for raising and / or lowering the winch without an auxiliary crane.

Vorteilhafterweise kann die Winde dabei mittels der Mittel zum Anheben und/oder Absenken der Winde von unten in einen Drehbühnenrahmen des Oberwagens eingehoben werden. In weiterhin vorteilhafter Weise kann die Winde mittels der Mittel zum Anheben und/oder Absenken der Winde auch wieder vom Drehbühnenrahmen des Oberwagens abgelassen werden. Hierdurch ist es auf einfache Art möglich, die Winde erst auf der Baustelle zu montieren, ohne dass hierfür ein Hilfskran nötig wäre. Die Winde kann hierbei z.B. über ein separates Transportfahrzeug zur Baustelle transportiert werden.Advantageously, the winch can be lifted by means of the means for raising and / or lowering the winch from below into a revolving platform frame of the superstructure. In a further advantageous manner, the winch can be lowered by the means for raising and / or lowering the winds again from the revolving platform frame of the superstructure. This makes it possible in a simple way to mount the winch on the construction site, without the need for an auxiliary crane would. The winch can be transported to the construction site, for example via a separate transport vehicle.

In weiterhin vorteilhafter Weise ist die Winde jedoch auch mittels eines Hilfskrans von oben in den Drehbühnenrahmen des Oberwagens einsetzbar. Hierdurch ist beim Aufbau mehr Flexibilität gegeben, da der Fahrzeugkran sowohl selbsttätig über die Mittel zum Anheben und/oder Absenken der Winde als auch über einen Hilfskran aufgerüstet werden kann.In a further advantageous manner, however, the winch can also be used by means of an auxiliary crane from above into the revolving platform frame of the superstructure. As a result, more flexibility is given in the construction, since the vehicle crane can be upgraded both automatically via the means for raising and / or lowering the winch as well as an auxiliary crane.

In weiterhin vorteilhafter Weise ist die erfindungsgemäße Winde mittels der Mittel zum Anheben und/oder Absenken der Winde am Oberwagen von einer ersten Stellung in eine bezüglich der Höhenrichtung des Fahrzeugkrans höher liegende Betriebsstellung und/oder von einer Betriebsstellung in eine bezüglich der Höhenrichtung des Fahrzeugskrans tiefer liegende erste Stellung bewegbar. Hierdurch ist es möglich, nach dem Betrieb die Winde abzusenken, um die zulässigen Maximalhöhen des Fahrzeugkrans beim Transport einzuhalten. An der Baustelle angekommen, kann die Winde dann wieder in ihre Betriebsstellung angehoben werden. Hierdurch ist es nicht mehr nötig, die Winde zum Transport komplett zu demontieren. Dennoch ist ein einfaches und selbständiges Herstellen der Einsatzbereitschaft über die Mittel zum Anheben und/oder Absenken der Winde möglich.In a further advantageous manner, the winch according to the invention by means of the means for raising and / or lowering the winch on the superstructure from a first position in a relation to the height direction of the vehicle crane higher operating position and / or from an operating position in a lower relative to the height direction of the vehicle crane first position movable. This makes it possible to lower the winch after operation in order to comply with the maximum permissible heights of the vehicle crane during transport. Arrived at the construction site, the winch can then be raised back to its operating position. As a result, it is no longer necessary to completely disassemble the winch for transport. Nevertheless, a simple and independent making the operational readiness on the means for raising and / or lowering the winch is possible.

Vorteilhafterweise ist die erste Stellung deshalb eine Transportstellung der Winde am Kran.Advantageously, the first position is therefore a transport position of the winch on the crane.

Weiterhin vorteilhafterweise ist die erste Stellung eine weitere Betriebsstellung, welche einen Betrieb des Fahrzeugkrans, insbesondere einen vollwertigen Betrieb des Fahrzeugkrans ohne Ballast, zuläßt. Insbesondere kann der Fahrzeugkran dabei vorteilhafterweise auch in der Transportstellung der Winde für leichtere Hübe wie z.B. Montagehübe eingesetzt werden, so dass die Transportstellung gleichzeitig eine weitere, gegebenenfalls eingeschränkte Betriebstellung darstellt.Further advantageously, the first position is a further operating position, which allows operation of the vehicle crane, in particular a full-value operation of the vehicle crane without ballast. In particular, the vehicle crane can advantageously also be used in the transport position of the winch for lighter strokes such as assembly strokes, so that the transport position simultaneously represents another, possibly restricted operating position.

Vorteilhafterweise hat die Winde damit drei mögliche Positionen:

  1. a) eine Betriebsstellung,
  2. b) eine niedrigere erste Stellung, welche gleichzeitig eine Transportstellung und eine weitere, gegebenenfalls eingeschränkte Betriebstellung darstellt, sowie
  3. c) Winde nicht am Kran.
Advantageously, the winch thus has three possible positions:
  1. a) an operating position,
  2. b) a lower first position, which simultaneously represents a transport position and another, possibly restricted operating position, as well as
  3. c) Do not winch on the crane.

In weiterhin vorteilhafter Weise weist die erfindungsgemäße Vorrichtung eine Aufnahme von Ballast auf, welche gleichzeitig die Mittel zum Anheben und/oder Absenken der Winde bildet. Der Ballast muss dabei während des Kraneinsatzes am hinteren Teil des Oberwagens angeordnet sein, um ein Gegengewicht für den Ausleger bzw. die Last zu bilden. Vor Beginn der Transportfahrt des Fahrzeugkrans wird der Ballast jedoch vom Oberwagen abgenommen und auf dem Unterwagen bzw. auf einem eigenen Transportfahrzeug abgelegt, um den Achslasten des Unterwagens gerecht zu werden. Eine Vorrichtung zur Aufnahme von Ballast dient dabei diesem Ab- und Aufnehmen des Ballastes am Oberwagen. Eine solche Vorrichtung zur Aufnahme von Ballast ist insbesondere aus der DE 20 2005 016 815 U1 bekannt. Erfindungsgemäß wird eine solche Vorrichtung zur Aufnahme von Ballast nun dazu verwendet, die Winde anzuheben und/oder abzusenken.In a further advantageous manner, the device according to the invention has a receptacle of ballast, which simultaneously forms the means for lifting and / or lowering the winch. The ballast must be arranged during the crane operation at the rear of the superstructure to form a counterweight for the boom or the load. Before the transport of the vehicle crane, however, the ballast is removed from the superstructure and stored on the undercarriage or on its own transport vehicle to meet the axle loads of the undercarriage. A device for receiving ballast serves this removal and receiving the ballast on the superstructure. Such a device for receiving ballast is in particular from the DE 20 2005 016 815 U1 known. According to the invention, such a device for receiving ballast is now used to raise and / or lower the winch.

In weiterhin vorteilhafter Weise umfassen die Mittel zum Anheben und/oder Absenken der Winde eine Palette, welche mittels Hubmitteln in vertikaler Richtung bewegbar ist, wobei die Winde und/oder der Ballast mittels der Palette in eine Betriebsstellung verfahren werden können. Vorteilhafterweise wird die Winde bzw. der Ballast dabei auf der Palette angeordnet und durch die Bewegung der Palette in die Betriebsstellung verfahren.In a further advantageous manner, the means for raising and / or lowering the winch comprise a pallet, which is movable by means of lifting means in the vertical direction, wherein the winch and / or the ballast can be moved by means of the pallet in an operating position. Advantageously, the winch or the ballast is thereby arranged on the pallet and moved by the movement of the pallet in the operating position.

In weiterhin vorteilhafter Weise ist die Palette dabei in der Betriebsstellung am Oberwagen verbolzbar. Die Palette verbleibt damit während dem Betrieb am Oberwagen und dient der Halterung von Winde bzw. Ballast.In a further advantageous manner, the range is in the operating position on the superstructure bolted. The pallet thus remains during operation on the superstructure and serves to hold the winch or ballast.

Vorteilhafterweise weist die Palette dabei Aufnahmen auf, insbesondere einstellbare Aufnahmen, auf welchen die Winde aufgestellt und definiert positioniert werden kann.Advantageously, the palette has recordings, in particular adjustable recordings, on which the winch can be positioned and defined.

Vorteilhafterweise liegt die Winde dabei in der Betriebsstellung auf der am Oberwagen verbolzten Palette auf. Die am Oberwagen verbolzte Palette dient damit der Sicherung der Winde in der Betriebsstellung.Advantageously, the winch is in the operating position on the bolted to the superstructure on pallet. The bolted to the superstructure pallet thus serves to secure the winch in the operating position.

Vorteilhafterweise ist die Winde am Oberwagen verbolzbar. Hierdurch kann die Winde, z. B. nachdem sie in ihre Betriebsstellung angehoben wurde, mit dem Oberwagen verbunden werden. Ebenso kann eine solche Verbolzung der Befestigung der Winde in der ersten Stellung, insbesondere einer Transportstellung, dienen.Advantageously, the winch is bolted to the superstructure. This allows the winch, z. B. after it has been raised to its operating position, be connected to the superstructure. Likewise, such a bolting of the attachment of the winch in the first position, in particular a transport position serve.

Vorteilhafterweise erfolgt die Verbolzung der Winde am Oberwagen dabei mittels eines Langloches, welches eine Bewegung der Winde von einer Betriebsstellung in eine bezüglich der Höhenrichtung des Fahrzeugkrans tiefer liegende erste Stellung, insbesondere eine Transportstellung, erlaubt. Ein solches Langloch erlaubt damit eine gewisse Bewegung der Winde am Oberwagen, und dient gleichzeitig der Sicherung der Winde in Betriebsstellung und der ersten Stellung.Advantageously, the bolting of the winch on the superstructure takes place by means of a slot, which allows a movement of the winch from an operating position to a lower position relative to the height direction of the vehicle crane first position, in particular a transport position. Such a slot thus allows a certain movement of the winch on the superstructure, and also serves to secure the winch in the operating position and the first position.

Vorteilhafterweise ist die Winde dabei in der ersten Stellung, insbesondere einer Transportstellung, sicherbar, insbesondere über einen Riegel, welcher den Bolzen im Langloch festlegt, so dass der Fahrzeugkran auch mit der in der ersten Stellung befindlichen Winde einsetzbar ist. Die erste Stellung stellt hierdurch eine weitere Betriebsstellung dar, so dass der Fahrzeugkran z. B. dazu verwendet werden kann, die Ballastplatten oder die Palette selbständig und ohne Hilfskran zu verladen.Advantageously, the winch is in the first position, in particular a transport position, securable, in particular via a bolt which fixes the bolt in the slot, so that the vehicle crane can also be used with the winch located in the first position. The first position thus represents a further operating position, so that the vehicle crane z. B. can be used to load the ballast plates or pallet independently and without auxiliary crane.

In der Betriebsstellung ist die Winde in weiterhin vorteilhafter Weise über die am Oberwagen verbolzte Palette sowie über die Verbolzung des Langlochs gesichert. Einer weiteren Sicherung bedarf es hierdurch nicht.In the operating position, the winch is secured in a further advantageous manner on the bolted to the superstructure range and on the Verbolzung the slot. Another backup is not required.

In weiterhin vorteilhafter Weise erfolgt die Sicherung der Winde in der ersten Stellung automatisch. Dies kann durch eine entsprechende Steuerung eines Riegelantriebs erfolgen, z.B. über einen Federantrieb mit entsprechenden Steuerflächen.In a further advantageous manner, the securing of the winch takes place automatically in the first position. This can be done by appropriate control of a latch drive, e.g. via a spring drive with corresponding control surfaces.

In weiterhin vorteilhafter Weise wird die Sicherung der Winde bei einem Anheben in die Betriebsstellung automatisch gelöst.

In den Figuren 1a und 1b ist ein Ausführungsbeispiel der erfindungsgemäßen Mittel zum Anheben und/oder Absenken der Winde 1 in unterschiedlich abgesenkten Positionen gezeigt. Die Mittel weisen dabei eine Palette 10 auf, welche über Seile 11 an dem Drehbühnenrahmen 4 des Oberwagens herangezogen und wieder abgelassen werden kann. Diese Anordnung dient dabei gleichzeitig auch dem Aufnehmen des Ballastes und ist in ihrer Ausführung näher in DE 20 2006 007 486 U1 beschrieben. Insbesondere kann die Palette 10 über die Seile 11 komplett an den Oberwagen herangezogen und mit diesem verbolzt werden, sowie zur Demontage der Winde bzw. des Ballastes vom Oberwagen entweder auf ein separates Transportfahrzeug, den Boden oder den Unterwagen abgelassen werden.In the FIGS. 1a and 1b an embodiment of the inventive means for raising and / or lowering the winch 1 is shown in different lowered positions. The means in this case have a pallet 10, which can be used on ropes 11 on the revolving platform frame 4 of the superstructure and drained again. This arrangement also serves to accommodate the ballast and is closer in their execution in DE 20 2006 007 486 U1 described. In particular, the pallet 10 can be pulled over the ropes 11 completely to the superstructure and bolted with this, as well as to dismantle the winch or ballast from the superstructure either on a separate transport vehicle, the floor or the undercarriage drained.

Die Hubmittel zum Betätigen der Seile 11 sind dabei im Drehbühnenrahmen 4 angeordnet und umfassen vorteilhafterweise Hydrozylinder, welche im wesentlichen horizontal angeordnet sind. Die Palette 10 ist dabei am Drehbühnenrahmen 4 in ihrer Betriebsstellung verbolzbar und sichert dabei die Winde 1. Dabei wird auch der nicht gezeigte Ballast über die Palette 10 am Oberwagen gehalten.The lifting means for actuating the cables 11 are arranged in the revolving platform frame 4 and advantageously comprise hydraulic cylinders, which are arranged substantially horizontally. The pallet 10 can be bolted to the revolving platform frame 4 in its operating position, thereby securing the winch 1. The ballast, not shown, is also held above the pallet 10 on the superstructure.

Die Palette 10 weist nun einstellbare Aufnahmen 8 auf, auf welchen die Winde 1 über entsprechende Positionierelemente 7 abgestellt und definiert positioniert werden kann. Eine weitere Befestigung der Winde 1 auf der Palette 10 ist dabei nicht vorgesehen.The pallet 10 now has adjustable seats 8, on which the winch 1 can be positioned and defined via corresponding positioning elements 7. A further attachment of the winch 1 on the pallet 10 is not provided.

Zur Montage der Winde 1 wird diese nun auf der Palette 10 positioniert, woraufhin die Palette 10 über die Seile 11 an dem Drehbühnenrahmen 4 von unten angehoben wird. Die Winde 1 ist hierdurch von unten in ihre Betriebsstellung anhebbar. Die Palette 10 weist dabei Laschen auf, über welche sie mit dem Drehbühnenrahmen 4 verbolzbar ist. Auch die Winde 1 wird in ihrer Betriebsstellung über Bolzen 6 an Verbolzpunkten 12 am Drehbühnenrahmen 4 mit Langlöchern 9 an der Winde 1 in ihrer Betriebsstellung verbolzt. Vor dem Selbstballastieren der Winde müssen die Bolzen 6 dabei auf der linken und rechten Seite des Drehbühnenrahmens 4 an den Verbolzpunkten 12 nach außen entriegelt sein. Nachdem die Winde nach oben gezogen wurde, werden die Bolzen 6 wieder nach innen verriegelt. Hierzu ist ein Gestänge 3 vorgesehen, welches eine Bedienung der Bolzen 6 von einem sicheren Stand aus ermöglicht.For mounting the winch 1, this is now positioned on the pallet 10, whereupon the pallet 10 is lifted over the ropes 11 on the revolving platform frame 4 from below. The winch 1 can thereby be raised from below into its operating position. The pallet 10 has tabs, via which it can be bolted to the revolving platform frame 4. The winch 1 is bolted in its operating position by bolts 6 at bolt points 12 on the revolving platform frame 4 with slots 9 on the winch 1 in its operating position. Before the self-ballasting of the winch bolts 6 must be unlocked on the left and right side of the revolving platform frame 4 at the Verbolzpunkten 12 outward. After the winch has been pulled up, the bolts 6 are locked in again. For this purpose, a linkage 3 is provided which allows operation of the bolt 6 from a safe stand.

In dieser Betriebsstellung ist die Winde 1 in Figur 2a gezeigt. Nach unten ist die Winde 1 dabei über die mit dem Drehbühnenrahmen 4 verbolzte Palette 10 festgelegt. Nach oben sowie gegen ein Verkippen ist sie über die Bolzen 6 gesichert, welche an den Verbolzpunkten 12 am Drehbühnenrahmen 4 und in die Langlöcher 9 an der Winde eingreifen.In this operating position the winch is 1 in FIG. 2a shown. Down the winch 1 is set over the bolted to the revolving platform frame 4 range 10. Upwards and against tilting it is secured over the bolts 6, which engage at the Verbolzpunkten 12 on the revolving platform frame 4 and in the slots 9 on the winch.

In Figur 2b ist dagegen die Transportstellung der Winde 1 gezeigt, bei welcher die Palette 10 abgelassen wurde, während die Bolzen 6 weiterhin gesteckt bleiben. Die Winde bewegt sich dadurch zunächst mit der Palette 10 entlang der Langlöcher 9 nach unten, bis die Langlöcher 9 mit ihren oberen Begrenzungen auf dem Bolzen 6 aufsitzen. Diese Transportstellung ist nochmals in Figur 3 zu sehen, wobei zu erkennen ist, dass in der Transportstellung die Winde 1 die gleiche Höhe aufweist wie die vordere Winde 2.In FIG. 2b on the other hand, the transport position of the winch 1 is shown, in which the pallet 10 has been drained, while the bolts 6 remain plugged. The winch thereby moves first with the pallet 10 along the slots 9 down until the slots 9 sit with their upper limits on the bolt 6. This transport position is again in FIG. 3 it can be seen that, in the transport position, the winch 1 has the same height as the front winch 2.

In Figur 4 ist nunmehr die erfindungsgemäße Winde 1 detaillierter gezeigt. Die Winde 1 weist dabei einen in ihre Drehachse integrierten Hydromotor auf, welcher die Winde antreibt. Die Winde ist dabei an einem Tragrahmen montiert, welcher die zwei parallel verlaufenden Langlöcher 9 zum Verbolzen mit dem Drehbühnenrahmen 4 aufweist. Die Langlöcher 9 weisen dabei eine untere Verbolzposition 6b auf, in welcher sich die Bolzen 6 in der Betriebsstellung befinden, sowie eine obere Bolzenposition 6a, in welcher sich die Bolzen in der Transportstellung befinden. Liegt die Winde 1 also über die Gegenelemente 7 in der Betriebsstellung auf den Aufnahmen 8 der Palette 10 auf, verhindern die Bolzen 6 in den Bolzenpositionen 6b eine Bewegung der Winde nach oben und zur Seite und damit ein Kippen der Winde. Wird die Palette 10 dagegen abgelassen, bewegt sich die Winde 1 nach unten, bis die Langlöcher 9 in den Bolzenpositionen 6a auf den Bolzen 6 aufliegen. Die Winde 1 wird in dieser Transportposition über die Riegel 50 gesichert, wobei die Riegel 50 über einen Verbolzantrieb 51 sowie einen Antriebshebel 53 bewegt werden. Dabei ist eine Steuerfläche 52 der Verbolzeinheit vorgesehen, an welcher ein Gegenelement an der Palette 10 angreift, so dass die Winde 1 in der Transportstellung automatisch verriegelt wird, wenn die Palette 10 weiter abgesenkt wird und umgekehrt wieder automatisch entriegelt wird, wenn die Winde 1 über die Palette 10 angehoben wird.In FIG. 4 now the winch 1 according to the invention is shown in more detail. The winch 1 in this case has a hydraulic motor integrated in its axis of rotation, which drives the winch. The winch is mounted on a support frame, which the two parallel slots 9 for bolting to the revolving platform frame 4 has. The elongated holes 9 in this case have a lower Verbolzposition 6b, in which the bolts 6 are in the operating position, and an upper pin position 6a, in which the bolts are in the transport position. If the winch 1 thus lies on the receptacles 8 of the pallet 10 via the counter elements 7 in the operating position, the bolts 6 in the bolt positions 6b prevent the winch from moving upwards and to the side and thus tilting the winch. On the other hand, if the pallet 10 is lowered, the winch 1 moves downwards until the elongated holes 9 rest on the bolt 6 in the pin positions 6a. The winch 1 is secured in this transport position on the bolt 50, wherein the bolt 50 via a Verbolzantrieb 51 and a drive lever 53 are moved. In this case, a control surface 52 of the bolt unit is provided, on which a counter-element on the pallet 10 engages, so that the winch 1 is automatically locked in the transport position when the pallet 10 is lowered further and vice versa automatically unlocked when the winch 1 over the pallet 10 is raised.

In Figur 5 ist noch einmal in einer perspektivischen Ansicht die Palette 10 gezeigt, wobei im mittleren Bereich die Aufnahmen 8 für die Winde sowie in den beiderseitigen Randbereichen Ballastplattformen 20 zur Aufnahme von Ballastelementen gezeigt sind.In FIG. 5 is once again shown in a perspective view of the pallet 10, wherein in the central region, the receptacles 8 for the winch and in the mutual edge areas ballast platforms 20 are shown for receiving ballast elements.

Die Verwendung des erfindungsgemäßen Fahrzeugkrans wird nun nochmals im Zusammenhang näher erläutert: Im Arbeitszustand des Fahrzeugkrans kann der Ausleger stark abgewippt werden, wobei in dieser flachen Stellung sämtliche Hubseile von den Hubwinden, in diesem Fall von Winde 1 und Winde 2, zur Spitze des Auslegers zu führen sind. Im Ausführungsbeispiel ist dabei lediglich in Fig. 3 die vordere Winde 2 gezeigt, wobei die hintere Winde 1 in ihrer Arbeitstellung höher zu positionieren ist. Dies ist z. B. in Figur 2a zu sehen, in welcher die Winde 1 in Betriebsstellung am Drehbühnenrahmen 4 gezeigt ist. Hierdurch kann jedoch die von der Straßenverkehrszulassungsordnung zugelassene Höhe überschritten werden.The use of the vehicle crane according to the invention will now be explained in more detail in context: In the working state of the vehicle crane, the boom can be tapped sharply, in this flat position all hoisting ropes of the hoist winches, in this case of winch 1 and winch 2, to the top of the boom lead. In the exemplary embodiment is only in Fig. 3 the front winch 2 shown, wherein the rear winch 1 is to be positioned higher in their working position. This is z. In FIG. 2a to see in which the winch 1 is shown in the operating position on the revolving platform frame 4. As a result, however, the height allowed by the Road Traffic Licensing Regulations may be exceeded.

Um zum Montieren oder zum Demontieren der Winde 1 keinen Hilfskran verwenden zu müssen, ist der Fahrzeugkran erfindungsgemäß mit den Mitteln zum Anheben und/oder Absenken der Winde 1 ausgestattet. Die Mittel zum Anheben und/oder Absenken der Winde umfassen dabei eine Palette 10, welche im Ausführungsbeispiel über Seile 11 gegenüber dem Drehbühnenrahmen 4 des Oberwagens anhebbar bzw. absenkbar ist. Gegebenenfalls können in einer alternativen Ausführungsform auch eine oder mehrere weitere Winden vorgesehen sein, welche mittels der Mittel zum Anheben und/oder Absenken der Winden angehoben und/oder abgesenkt werden können.In order to use for mounting or dismounting the winch 1 no auxiliary crane, the vehicle crane according to the invention with the means for raising and / or lowering the winch 1 is equipped. The means for raising and / or lowering the winch comprise a pallet 10, which in the exemplary embodiment can be raised or lowered via ropes 11 relative to the revolving platform frame 4 of the superstructure. Optionally, in one alternative embodiment, one or more further winches may be provided, which may be raised and / or lowered by the means for raising and / or lowering the winches.

Die in Figur 3 zu sehende vordere Winde 2 kann aufgrund der Lage der Palette 10 dagegen im Ausführungsbeispiel nicht selbsttätig abgesenkt oder angehoben werden. Sie ist jedoch ohnehin niedriger angeordnet als die hintere Winde 1 in ihrer Betriebsstellung, so dass ein Absenken zum Transport nicht nötig ist.In the FIG. 3 On the other hand, due to the position of the pallet 10, the front winch 2 to be seen can not be automatically lowered or raised in the exemplary embodiment. However, it is anyway arranged lower than the rear winch 1 in its operating position, so that a lowering for transport is not necessary.

Die Winde 1 ist nun so gestaltet, dass sie sowohl von einem Hilfskran von oben in den Drehbühnenrahmen 4 eingesetzt, als auch von unten in den Drehbühnenrahmen 4 eingehoben werden können. Hierzu sind auf der Palette 10 einstellbare Aufnahmen 8 vorgesehen, auf denen die Winden abgestellt und definiert positioniert werden können. Eine weitere Befestigung ist hierbei nicht notwendig. Nach dem aus der DE 20 2005 016 815 U1 bekannten Anheben der Palette 10 in die vorgesehene Verbolzposition am Drehbühnenrahmen 4 befinden sich dann auch die Winden in ihren Verbolzpositionen. Hierzu sind Bolzen 6 vorgesehen, welche in die Verbolzposition der Winde 1 gesteckt werden können, so dass der Kran vollwertig arbeiten kann. Damit das Verbolzen von einem sicheren Stand aus erfolgen kann, ist ein Gestänge 3 vorgesehen, über welches das Verbolzen der Winde in ihrer Arbeitsposition von der Oberseite des Drehbühnenrahmens 4 aus möglich ist.The winch 1 is now designed so that they can be used both by an auxiliary crane from above in the revolving platform frame 4, as well as from below into the revolving platform frame 4 can be lifted. For this purpose, 10 adjustable recordings 8 are provided on the pallet on which the winches can be parked and defined. Another attachment is not necessary here. After the out of the DE 20 2005 016 815 U1 known lifting the pallet 10 in the intended Verbolzposition on the revolving platform frame 4 are then also the winches in their Verbolzpositionen. For this purpose, bolts 6 are provided, which can be plugged into the Verbolzposition the winch 1, so that the crane can work fully. So that the bolt can be made from a safe stand, a linkage 3 is provided, via which the bolting of the winch in its working position from the top of the revolving platform frame 4 is possible.

Ist ein Verfahren des Krans notwendig, so kann die Palette 10 mit dem Ballast abgelassen und vom Kran entfernt werden. Hierdurch wird aber das untere Lager der Winde 1 entfernt. Da die Winde 1 im Drehbühnenrahmen 4 verbolzt bleibt und die Bolzen 6 an der Winde an dem Langloch 9 aufgenommen sind, senkt sich die Winde um einen definierten Weg (Langlochlänge) ab. Hierdurch wird die maximal zulässige Höhe im Bereich der STVZO erreicht.If a procedure of the crane is necessary, the pallet 10 can be drained with the ballast and removed from the crane. As a result, however, the lower bearing of the winch 1 is removed. Since the winch 1 remains bolted in the revolving platform frame 4 and the bolts 6 are added to the winch on the slot 9, the winch lowers by a defined path (long hole length). This achieves the maximum permitted height in the STVZO area.

Damit der Kran die Ballastplatten und die Palette 10 selbständig und ohne Hilfskran verladen kann, ist es notwendig, dass die abgesenkte Winde 1 einsatzfähig bleibt. Hierzu wird ein Riegel 50 vorgeschoben, der die Winde 1 in der abgesenkten Position festhält. So kann der Kran auch ohne Gegengewichte mit eingeschränkter Traglast arbeiten. Die Steuerung der Riegel 50 erfolgt automatisch über einen Antrieb 51 (Feder, elektrischer oder hydraulischer oder sonstiger Motor, etc.) und eine Steuerung. Im Ausführungsbeispiel ist dabei ein Gestänge vorgesehen, das beim Abheben der Winde 1 von der Palette 10 den Riegel 50 automatisch vorschiebt.So that the crane can load the ballast plates and the pallet 10 independently and without auxiliary crane, it is necessary that the lowered winch 1 remains operational. For this purpose, a bolt 50 is advanced, which holds the winch 1 in the lowered position. Thus, the crane can work without counterweights with limited payload. The control of the bolt 50 takes place automatically via a drive 51 (spring, electric or hydraulic or other motor, etc.) and a controller. In the embodiment, a linkage is provided, which automatically advances the bolt 50 when lifting the winch 1 from the pallet 10.

Der Einsatz eines Hilfskrans ist folglich auch bei erneutem Montieren auf der neuen Baustelle nicht notwendig. Bei erneutem Anbringen der Palette 10 wird der Riegel 50 wieder automatisch zurückgeschoben, da die Palette 10 an der Steuerfläche 52 der Verbolzeinheit angreift, bevor die Palette 10 die Winde 1 anhebt.The use of an auxiliary crane is therefore not necessary when re-mounting on the new site. When re-attaching the pallet 10, the bolt 50 is automatically pushed back again, since the pallet 10 engages the control surface 52 of the bolt unit before the pallet 10 lifts the winch 1.

Erfindungsgemäß wird es so bei minimalem zusätzlichen konstruktiven Aufwand ermöglicht, die Einsatzbereitschaft des erfindungsgemäßen Fahrzeugkrans ohne Hilfskran selbständig auf der Baustelle herzustellen und gleichzeitig die Transportvorschriften hinsichtlich der maximal zulässigen Höhe sowie der Achslasten des Fahrzeugkrans einzuhalten.According to the invention it is thus possible with minimal additional design effort to independently prepare the operational readiness of the vehicle crane according to the invention without auxiliary crane on site and at the same time to comply with the transport regulations in terms of maximum allowable height and axle loads of the vehicle crane.
