Description

Die Erfindung betrifft eine mobile Hubarbeitsbühne für Arkadengebäude mit einem Fahrgestell mit seitlich angeordneten Rollelementen, an dem an einer ersten vertikalen Drehachse ein Horizontalschwenkarm gelagert ist, und mit einem Armausleger, der an einer zweiten vertikalen Drehachse an dem Horizontalschwenkarm gelagert ist und der einen gekröpften Verbindungsarm aufweist, der einen Arbeitskorb trägt.The invention relates to a mobile aerial work platform for arcade building with a chassis with laterally arranged rolling elements, on which a horizontal pivot arm is mounted on a first vertical axis of rotation, and with an arm boom, which is mounted on a second vertical axis of rotation on the Horizontalschwenkarm and having a cranked connecting arm carrying a work basket.

Außerdem betrifft die Erfindung ein Verfahren zum Durchführen von Wartungsarbeiten in einem Arkadengebäude mit einer solchen mobilen Hubarbeitsbühne.Moreover, the invention relates to a method for performing maintenance work in an arcade building with such a mobile aerial work platform.

Aus der DE 296 10 630 U1 ist eine gattungsgemäße Hubarbeitsbühne bekannt welche dem Oberbegriff des unabhängigen Anspruchs 1 entspricht. Das Fahrgestell dieser Hubarbeitsbühne ist ein Lastkraftwagen. Der Horizontalschwenkarm mit zwei vertikalen Drehachsen ermöglicht, bezogen auf den Arbeitsbereich einer Hubarbeitsbühne mit lediglich einer Drehachse, eine Verkürzung der Länge des Armauslegers und eine vorteilhafte Schwerpunktveränderung in Bezug auf das Fahrgestell, die er ermöglicht, weniger oder kürzere ausfahrbare Stützen vorzusehen. Allerdings ist die bekannte Hubarbeitsbühne für den Einsatz im Straßenverkehr konzipiert und damit viel zu groß, vor allem zu hoch, um innerhalb von Gebäuden eingesetzt werden zu können.From the DE 296 10 630 U1 a generic aerial work platform is known which corresponds to the preamble of independent claim 1. The chassis of this aerial work platform is a truck. The horizontal pivoting arm with two vertical axes of rotation, based on the working range of an aerial work platform with only one axis of rotation, allows a shortening of the length of the arm boom and a favorable change of center of gravity with respect to the chassis, allowing it to provide fewer or shorter extendable supports. However, the known aerial work platform is designed for use in traffic and thus far too large, especially too high to be used inside buildings.

Aus der DE 198 13 278 A1 ist eine mobile Hubarbeitsbühne ohne Horizontalschwenkarm bekannt, die aufgrund ihres mehrteiligen Fahrgestells für das Rangieren und Arbeiten innerhalb von Gebäuden geeignet ist. Allerdings sind mit dieser bekannten Hubarbeitsbühne Arbeiten im Dachbereich eines Arkadengebäudes, also im Bereich eines Lichtbandes oder einer Lichtkuppel, nur von der direkt darunter liegenden Innenfläche im Basisgeschoss möglich. Diese Innenfläche ist aber meist stark genutzt, so dass vor Beginn und nach Ende Arbeiten mit der Hubarbeitsbühne umfangreiche Aufräumarbeiten erforderlich sind.From the DE 198 13 278 A1 is a mobile aerial work platform without horizontal swivel arm known, which is suitable for maneuvering and working within buildings due to its multi-part chassis. However, with this known aerial work in the roof area of an arcade building, ie in the range of a light band or a dome light, only from the directly underlying inner surface in the basement floor possible. However, this inner surface is usually heavily used, so that before starting and after the end of work with the aerial work platform extensive cleanup is required.

Die US-PS 4 646 875 zeigt ein Fahrzeug,das einen Arbeitsbereich unterhalb der eigenen Standfläche ermöglicht, also für Brückenwartungsarbeiten ausgebildet ist. Es ist bei dem Fahrzeug nicht möglich, den Armausleger, also den gesamten Bereich jenseits der zweiten Drehachse, über den ersten Armabschnitt hinweg zu bewegen. Die verschiedenen Knickachsen erlauben lediglich eine Bewegung nach hinten hin. Eine Transportstellung mit flach gelegten Auslegerarmen, bei der insgesamt eine sehr kurze Fahrzeuglänge gegeben ist, ist nicht erreichbar. Im Einsatz muss eine Abschaltung vorgenommen werden, wenn der am zweiten Drehgelenk befestigte zweite Armausleger an den ersten Arm bewegt wird, da es sonst zu einer Kollision zwischen den Achsen kommen würde.The U.S. Patent 4,646,875 shows a vehicle that allows a workspace below its own footprint, that is designed for bridge maintenance work. It is not possible for the vehicle to move the arm boom, ie the entire area beyond the second axis of rotation, past the first arm section. The different bending axes allow only a movement towards the rear. A transport position with flat-laid boom arms, in which a total of a very short vehicle length is given, is not achievable. In use, a shutdown must be made when the attached second pivot arm second arm arm is moved to the first arm, otherwise it would come to a collision between the axles.

Aufgabe der Erfindung ist es daher, eine Hubarbeitsbühne der eingangs genannten Art so weiter zu entwickeln, dassThe object of the invention is therefore to develop an aerial work platform of the type mentioned so that

Sie durch Türen von Gebäuden mit üblichen Öffnungsmaßen fahren kann und/oder mit vorhandenen Aufzügen transportierbar ist und dass sie insbesondere zur Wartung und Reinigung von Lichtbändern und Kuppeln von einem Randbereich der darunter liegenden Fläche und/oder von einem Galeriegang aus geeignet ist.It may pass through doors of buildings of conventional opening dimensions and / or be transportable with existing elevators and that it is particularly suitable for the maintenance and cleaning of light bands and domes from an edge region of the underlying surface and / or from a gallery aisle.

Diese Aufgabe wird durch eine mobile Hubarbeitsbühne mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a mobile aerial work platform with the features of claim 1.

Diese Lösung hat den Vorteil, dass eine wesentliche Verkürzung der Fahrzeuglänge und damit eine gute Rangierbarkeit innerhalb von Gebäudegängen erreicht werden. Die Befestigung des Arbeitskorbs mit der Unterseite an dem gekröpften Verbindungsarm vergrößert den Arbeitsbereich der Hubarbeitsbühne um die Größe der im Arbeitskorb befindlichen Person bzw. ermöglicht bei gegebenem Arbeitsbereich eine entsprechende Verkürzung des Armauslegers. Eine weitere Verkürzung im Transportzustand der Hubarbeitsbühne ermöglicht die Anordnung des Horizontalschwenkarms, der mit seiner ersten Drehachse so nah wie möglich an der Rückseite des Fahrgestells bzw. im rückwärtigen Bereich der Abstützlänge der Rollelemente gelagert ist und der im Bereich seines anderen Endes die zweite Drehachse trägt, wodurch der Armausleger insgesamt weiter hinten gegenüber dem Fahrgestell positioniert ist.This solution has the advantage that a significant shortening of the vehicle length and thus good maneuverability within building passages are achieved. The attachment of the platform to the bottom of the cranked link increases the working area of the platform by the size of the platform located in the platform Person or allows for a given work area a corresponding shortening of the arm boom. A further reduction in the transport state of the aerial work platform allows the arrangement of the Horizontalschwenkarms, which is mounted with its first axis of rotation as close as possible to the back of the chassis or in the rear region of the support length of the rolling elements and carries in the region of its other end the second axis of rotation whereby the arm boom is positioned further back from the chassis.

Die endseitige Lagerung des Horizontalarms ermöglicht es, das Fahrgestell längsseits von Barrieren im Gebäude wie Brüstungen oder Geländern zu positionieren, den Horizontalarm mit dem daran gelagerten Armausleger seitlich über die Barriere zu schwenken und so den Armausleger in einem Luftraum, der sich neben der Stellfläche des Fahrgestells befindet, auszurichten. Insbesondere ist es möglich, die erfindungsgemäße Hubarbeitsbühne in Gebäudegängen zu und durch Türen zu bewegen, mit Personenaufzügen mit einer Tragkraft von drei Tonnen zu einem Galeriegang im Obergeschoss eines Arkadengebäudes zu transportieren und dann über die dortige Brüstung hinweg im Luftraum unterhalb einer Lichtkuppel oder dergleichen zu operieren. Es ist damit nicht mehr notwendig, die Innenfläche im Basisgeschoss des Arkadengebäudes zu befahren.The end-to-end support of the horizontal arm allows the chassis to be positioned alongside barriers in the building, such as parapets or railings, to laterally pivot the horizontal arm with the arm arm mounted thereon over the barrier, thus placing the arm boom in an air space adjacent to the footprint of the chassis is to align. In particular, it is possible to move the aerial work platform according to the invention in and out of doors, to transport with passenger lifts with a capacity of three tons to a gallery corridor on the upper floor of an arcade building and then operate over the local parapet in the air space below a dome light or the like , It is therefore no longer necessary to drive on the inner surface in the basement of the arcade building.

Das ausgewogene Konstruktionsprinzip macht ausfahrbare Stützstreben entbehrlich und reduziert damit den Platzbedarf für die Aufstellung erheblich.The balanced construction principle eliminates the need for retractable struts and thus considerably reduces the space required for installation.

Der gekröpfte Verbindungsarm bewirkt auch, dass die Oberkante des Arbeitskorbs gegenüber dem nieder gelegten Armausleger abgesenkt ist, wodurch die Durchfahrtshöhe reduziert ist. Außerdem bewirkt der gekröpfte Verbindungsarm, dass der Massenschwerpunkt bei einem vollständig aufgerichteten Armausleger im oder am Stützbereich des Fahrgestells liegt.The cranked link arm also causes the top edge of the work cage to be opposite the lowered boom is lowered, whereby the passage height is reduced. In addition, the cranked link arm causes the center of gravity of a fully erected boom to lie in or on the support of the chassis.

Insbesondere ist der gekröpfte Verbindungsarm so lang bzw. der Kröpfungswinkel so groß, dass die Oberkante des Arbeitskorbs nach oben nicht über den Armausleger hinaus ragt. Ein bevorzugter Kröpfungswinkel zwischen der Längsachse des Armauslegers und dem Verbindungsarm beträgt 120° bis 150°.In particular, the cranked connecting arm is so long or the crank angle is so great that the upper edge of the working cage does not protrude upwards beyond the arm extension. A preferred crank angle between the longitudinal axis of the arm jib and the connecting arm is 120 ° to 150 °.

Vorteilhaft ist eine Lagerung des Armauslegers an einer Armauslegerschwenkachse, welche an wenigstens einem Grundträger angeordnet ist, der auf einem an der zweiten Drehachse drehbar gelagerten Drehteller befestigt ist. Zwischen dem Grundträger und dem Armausleger kann wenigstens ein Hydraulikzylinder wirken, mit dem der Armausleger aufzurichten ist und zwar unabhängig von seiner Rotation um die zweite Drehachse.Advantageously, a bearing of the arm arm on a Armauslegerschwenkachse, which is arranged on at least one base support which is mounted on a rotatably mounted on the second axis of rotation turntable. Between the base support and the arm boom, at least one hydraulic cylinder can act with which the arm boom is erected, regardless of its rotation about the second axis of rotation.

Der Grundträger sollte schräg angestellt sein und von der mit dem Arbeitskorb verbundenen Seite des Armauslegers weg weisen. Hierdurch wird wiederum der Armausleger in Transportstellung in Bezug auf das Fahrgestell weiter hinten positioniert.The base girder should be inclined and pointed away from the side of the jib connected to the platform. As a result, in turn, the arm boom is positioned in the transport position with respect to the chassis further back.

Um die Masse der Hubarbeitsbühne zu reduzieren und damit eine Nutzung vorhandener Personenaufzüge zu ermöglichen, ist vorzugsweise vorgesehen, das Fahrgestell aus einem Leichtbauwerkstoff zu bilden und über wenigstens ein Massenelement enthält, das hinter der ersten Drehachse positionierbar ist, auszutarieren. Hierbei kann es sich beispielsweise um Bleigewichte oder um mit Sand befüllte Kästen handeln. Die Leichtbauweise reduziert die Gesamtmasse, während die Ausgleichsgewichte Massenpunkte bilden, die die Standsicherheit im Betrieb des Armauslegers erhöhen.In order to reduce the mass of the aerial work platform and thus to allow the use of existing passenger elevators, it is preferably provided to form the chassis from a lightweight material and to balance over at least one mass element that can be positioned behind the first axis of rotation. This can be for example to trade lead weights or sand filled boxes. The lightweight design reduces the total mass, while the balance weights form mass points that increase the stability in the operation of the arm boom.

Ebenfalls als Ausgleichsgewicht kann eine Antriebseinheit wirken, die insbesondere so im Fahrgestell positionierbar ist, dass ihr Schwerpunkt von der ersten Drehachse entfernt liegt. Eine palettierte Anordnung bietet den Vorteil, dass die Antriebseinheit wählbar ist, beispielsweise elektrisch für den Betrieb innerhalb eines Gebäudes oder mit zusätzlichem Verbrennungsmotor für den Betrieb im Außenbereich. Außerdem kann im Störungsfall ein einfacher Austausch vorgenommen werden. Hierzu ist jede Antriebseinheit so aufgebaut, dass Sie am Fahrgestell nur noch mit wenigen Hydraulikleitungen und einem elektrischen Steckkontakt für die Steuerung verbunden werden muss.Also, as a counterweight can act a drive unit, which is in particular positionable in the chassis, that their center of gravity is away from the first axis of rotation. A palletized arrangement offers the advantage that the drive unit can be selected, for example electrically for operation within a building or with an additional internal combustion engine for outdoor operation. In addition, a simple replacement can be made in case of failure. For this purpose, each drive unit is designed so that you only need to be connected to the chassis with a few hydraulic lines and an electrical plug-in contact for the controller.

Gleisketten, insbesondere Gummiketten, sind wegen ihrer geringen Flächenpressung besonderes für empfindliche Böden in Gebäuden geeignet.Crawlers, especially rubber tracks, are particularly suitable for sensitive floors in buildings because of their low surface pressure.

Vorteilhaft zur Reduzierung der Fahrzeuglänge ist die Unterteilung des Armauslegers in mehrere Teleskopelemente und den gekröpften Verbindungsarm. Insbesondere sind drei Teleskopelemente vorgesehen. Gewichtssparend ist eine Ausführungsform, bei der nur zwei der Teleskopelemente über einen Hydraulikzylinder gegeneinander verschiebbar sind und ein weiteres Paar manuell verstellbar ist. Damit kann vor Aufnahme des Betriebs des Armauslegers eine Längenanpassung an die örtlichen Gegebenheiten vorgenommen werden, wohingegen eine Anpassung im Betrieb dann ferngesteuert über den Hydraulikzylinder möglich ist.Advantageous for reducing the vehicle length is the subdivision of the arm boom into a plurality of telescopic elements and the bent connecting arm. In particular, three telescopic elements are provided. Weight saving is an embodiment in which only two of the telescopic elements via a hydraulic cylinder are mutually displaceable and another pair is manually adjustable. This can be done before starting the operation of the arm arm, a length adjustment to the local conditions, whereas an adjustment during operation is then possible remotely via the hydraulic cylinder.

Um die Fahrzeuglänge und das Fahrzeuggewicht beim Transport noch weiter zu reduzieren, ist bei einer bevorzugten Ausführungsform der Erfindung vorgesehen, dass der Arbeitskorb mit dem gekröpften Verbindungsarm eine von dem Armausleger abnehmbare Arbeitskorbeinheit bildet. Diese wird über einfache Bolzenverbindungen mit dem vordersten Teleskopelement verbunden.In order to further reduce the vehicle length and the vehicle weight during transport, it is provided in a preferred embodiment of the invention that the work basket forms with the cranked connecting arm a detachable from the arm boom work basket unit. This is connected via simple bolt connections with the foremost telescopic element.

Wenn die Arbeitskorbeinheit im Bereich ihres Massenschwerpunkts wenigstens ein Rad aufweist, kann sie von einer Person ohne großen Kraftaufwand nach Art einer Sackkarre bewegt werden, wobei der Arbeitskorb noch zum Transport von Werkzeug zum Einsatzort nutzbar ist.If the work basket unit has at least one wheel in the region of its center of mass, it can be moved by a person without much effort in the manner of a sack truck, wherein the work basket can still be used to transport tools to the place of use.

Vorteilhafterweise findet die mobile Hubarbeitsbühne Verwendung in einem Verfahren zum Durchführen von Wartungsarbeiten in einem Arkadengebäude mit einer mobilen Hubarbeitsbühne.Advantageously, the mobile aerial work platform is used in a method of performing maintenance work in an arcade building with a mobile aerial work platform.

Hier bietet die vorstehend beschriebene Kinematik der Hubarbeitsbühne mit ihrem Horizontalschwenkarm den Vorteil, dass sowohl eine kurze Konfiguration möglich ist, die den Transport innerhalb eines Gebäudes erleichtert, wie auch eine entsprechende Beweglichkeit gegeben ist, um von einem Galeriegang aus den Armausleger mit Arbeitskorb im Luftraum eines Arkadengebäudes zu positionieren.Here, the above-described kinematics of the aerial work platform with its horizontal swivel arm has the advantage that both a short configuration is possible, which facilitates the transport within a building, as well as a corresponding mobility is given by a gallery walk from the arm boom with work in the airspace of a Arcade building to position.

Die Hubarbeitsbühne 100 umfasst, wie insbesondere die Fig. 3a und 3b zeigen, im Wesentlichen:

  • ein Fahrgestell 10 mit Gummiketten 11, 12,
  • einen darauf an einer ersten Drehachse 21 gelagerten, Horizontalschwenkarm 20, an dem wiederum ein Armausleger 30 mit drei Teleskopelementen 31, 32, 33 an einer Armauslegerschwenkachse 34 gelagert ist, und
  • einen gekröpften Verbindungsarm 40, an dem ein Arbeitskorb 40 befestigt.
The aerial work platform 100 includes, in particular the Fig. 3a and 3b show, essentially:
  • a chassis 10 with rubber tracks 11, 12,
  • a mounted thereon on a first axis of rotation 21, horizontal pivot arm 20 to which in turn an arm boom 30 is mounted with three telescopic elements 31, 32, 33 on a Armauslegerschwenkachse 34, and
  • a cranked link arm 40 to which a work cage 40 is attached.

Fig. 3a zeigt die Hubarbeitsbühne 100 in ihrer Transportstellung in Seitenansicht. Der Arbeitskorb 40 ist an der Rückseite 14 des Fahrgestells 10 positioniert. Der Horizontalschwenkarm 20 ist um die erste Drehachse 21 zu einer Vorderseite 15 hin geschwenkt. Fig. 3a shows the aerial work platform 100 in its transport position in side view. The work basket 40 is positioned on the rear side 14 of the chassis 10. The horizontal pivot arm 20 is pivoted about the first axis of rotation 21 to a front side 15.

An einer zweiten Drehachse 22 des Horizontalschwenkarms 20 ist ein Drehteller gelagert, von dem zwei Grundträger 35 schräg nach hinten laufen, an deren freiem Ende die Armauslegerschwenkachse 34 angeordnet ist.At a second axis of rotation 22 of the horizontal pivot arm 20, a turntable is mounted, run from the two base support 35 obliquely to the rear, at the free end of the Armauslegerschwenkachse 34 is arranged.

Zwischen den beiden Grundträgern 35 ist der eigentliche Armausleger 30 angeordnet, wie die Draufsicht derselben Stellung in Fig. 3b zeigt. An jeder Seite ist zwischen Grundträger 35 und Armausleger 30 je ein Hydraulikzylinder 36 angeordnet, um den Armausleger 30 anheben zu können.Between the two base beams 35, the actual arm boom 30 is arranged, as the top view of the same position in Fig. 3b shows. On each side between the base support 35 and arm jib 30 each have a hydraulic cylinder 36 is arranged to lift the boom arm 30 can.

In Fig. 3a und 3b ist mit L eine Abstützlänge gekennzeichnet, die der Länge der Berührungsfläche der Gleisketten 11, 12 mit dem Untergrund entspricht. Wesentlich ist, dass die erste Drehachse 21 so weit wie möglich in der hinteren Hälfte der Abstützlänge L angeordnet ist. Dadurch wird unter anderem der Vorteil erreicht, dass von der ersten Drehachse 21 aus gemessen eine größtmögliche Restlänge der Gleisketten 11, 12 zur Verfügung steht, um den in der Arbeitsstellung gemäß Fig. 2c nach vorn gedrehten Armausleger abzustützen.In Fig. 3a and 3b L is a support length which corresponds to the length of the contact surface of the track chains 11, 12 with the ground. It is essential that the first axis of rotation 21 is arranged as far as possible in the rear half of the support length L. As a result, inter alia, the advantage is achieved that, measured from the first axis of rotation 21, the greatest possible residual length of the track chains 11, 12 is available in order to accommodate the position in the working position Fig. 2c support arm arm turned forward.

Die kompakte Bauweise der Hubarbeitsbühne ergibt für eine maximale Verkehrslast im Arbeitskorb 40 von 120 kg eine Höhe von unter 2m, eine Breite von 1,75m und eine Länge von ca. 3m bei abgenommener Arbeitskorbeinheit bzw. ca. 5m mit angesetzter Arbeitskorbeinheit. Der Freiraum unterhalb des Horizontalschwenkarms 20 beträgt ca. 1,40 m. Er definiert die maximale Brüstungshöhe, über die hinweg mit der Hubarbeitsbühne gearbeitet werden kann.The compact design of the aerial work platform results in a maximum traffic load in the work basket 40 of 120 kg, a height of less than 2m, a width of 1.75m and a length of about 3m with removed work basket unit or about 5m with attached work basket unit. The free space below the horizontal pivot arm 20 is approximately 1.40 m. It defines the maximum parapet height that can be used to work with the aerial work platform.

Arbeitskorb 40 und Verbindungsarm 41 sind, wie Fig. 4 zeigt, zu einer abnehmbaren Arbeitskorbeinheit verbunden, die über ein Koppelelement 43 am vordersten Teleskopelement 33 des Armauslegers 30 zu befestigen ist. Ein Stützrad 42 ist zwischen dem Verbindungsarm 41 mit dem Koppelelement 43 und dem Arbeitskorb 40 mit einem Steuerpult 44 positioniert. Die von den Elementen rechts und links des Stützrads 42 hervorgerufenen Drehmomente heben sich etwa auf, so dass die Arbeitskorbeinheit von einer Person leicht geschoben werden kann.Work basket 40 and connecting arm 41 are as Fig. 4 shows, connected to a detachable work basket unit which is to be fastened via a coupling element 43 on the foremost telescopic element 33 of the arm arm 30. A support wheel 42 is positioned between the connecting arm 41 with the coupling element 43 and the work cage 40 with a control panel 44. The of the elements right and left of the Support wheel 42 caused torques lift up on about so that the work basket unit can be easily pushed by a person.

Fig. 1 zeigt eine Hubarbeitsbühne 100 innerhalb eines Arkadengebäudes 200. Es sind mehrere mögliche Arbeitsstellungen des Armauslegers 30 zugleich dargestellt:

  • Im unteren Bildbereich ist der Armausleger 30 horizontal ausgerichtet. Durch Ausschieben der Teleskopelemente 30...32 kann der Arbeitskorb 40 zwischen den beiden unten dargestellten Positionen verschoben werden.
  • Im linken Bildbereich ist der Armausleger 30 maximal aufgerichtet und ausgefahren.
Fig. 1 shows an aerial work platform 100 within an arcade building 200. There are several possible working positions of the arm jib 30 shown simultaneously:
  • In the lower part of the picture arm arm 30 is aligned horizontally. By pushing out the telescopic elements 30 ... 32 of the work basket 40 can be moved between the two positions shown below.
  • In the left image area of the arm boom 30 is erected and extended maximum.

Dadurch, dass der Arbeitskorb 40 mit seiner Unterseite an dem Armausleger 30 angebracht ist, erhöht sich der vom Arbeitskorb 40 erreichbare Arbeitsbereich durch die Größe der darin befindlichen Person selber. Diese kann maximal in einem Bereich arbeiten, der mit einer Kurve 101 gekennzeichnet ist. Ist ein Teleskopelement eingeschoben, so ist noch der mit einer Kurve 102 gekennzeichnete Arbeitsbereich erreichbar.The fact that the work basket 40 is mounted with its underside on the arm boom 30, the work area achievable by the work basket 40 increases by the size of the person therein. This can work a maximum in an area which is marked with a curve 101. If a telescopic element is inserted, the work area marked with a curve 102 can still be reached.

Das Fahrgestell 10 ist auf einer Zwischendecke 210 in dem Arkadengebäude 200 aufstellbar und kann dann mit dem Armausleger 30 über eine Brüstung 214 hinweg in einem Luftraum 206 ausgerichtet werden. Es können so Seitenfenster 204 und eine Glaskuppel 202 erreicht werden und zwar sogar dann, wenn das Fahrgestell in einem Gang unterhalb einer Geschossdecke oder Dachfläche 208 positioniert ist, wie in den Fig. 2a bis 2c dargestellt ist.The chassis 10 can be erected on a false ceiling 210 in the arcade building 200 and can then be aligned with the arm boom 30 across a parapet 214 in an air space 206. Thus, side windows 204 and a glass dome 202 can be achieved even when the undercarriage is positioned in a corridor below a floor slab or roof surface 208, as in FIGS Fig. 2a to 2c is shown.

Fig. 2a zeigt eine Ausgangssituation, in der die Hubarbeitsbühne mit ihrem Fahrgestell 10 auf einem Galeriegang 211 positioniert ist. Sie wird schräg gestellt und zwischen zwei Säulen 212 in Richtung der Brüstung 214 gefahren, wie durch den Pfeil angedeutet. Anders als in der in den Fig. 3a und 3b gezeigten Transportstellung, ist hier beim Einfädeln zwischen die Säulen 212 der Horizontalschwenkarm 20 zur Rückseite des Fahrgestells 10 hin, also nach links oben in Fig. 2a, geschwenkt. Der Arbeitskorb 40 befindet sich über der Brüstung 214, die einen Luftraum 206 begrenzt. Fig. 2a shows an initial situation in which the aerial work platform with her chassis 10 on a gallery aisle 211 is positioned. It is tilted and moved between two columns 212 in the direction of the parapet 214, as indicated by the arrow. Unlike in the in the Fig. 3a and 3b shown transport position is here when threading between the pillars 212 of the horizontal pivot arm 20 to the rear of the chassis 10 back, so left above in Fig. 2a , panned. The work basket 40 is located above the parapet 214 which defines an air space 206.

In Fig. 2b ist bereits der gesamte Armausleger 30 mit Arbeitskorb 40 im Luftraum 206 positioniert. Der Horizontalschwenkarm 20 ist bereits annähernd quer zur Längsachse des Fahrgestells 10 gestellt, wodurch auch die zweite Drehachse 22 im Luftraum positioniert ist.In Fig. 2b already the entire boom arm 30 with work basket 40 is positioned in the air space 206. The horizontal pivot arm 20 is already placed approximately transversely to the longitudinal axis of the chassis 10, whereby the second axis of rotation 22 is positioned in the air space.

In Fig. 2c ist das Fahrgestell 10 in der für den Betrieb des Armauslegers vorgesehenen Lage längsseits der Brüstung 214 zwischen den Säulen 212 positioniert. Der Horizontalschwenkarm 20 ist um 90° querab zur Längsachse des Fahrgestells 10 ausgerichtet und kragt damit maximal in den Luftraum 206 aus. Der Armausleger 30 ist im Luftraum 206 nahe der Brüstung 214 positioniert und noch parallel dazu ausgerichtet, so dass auch der Arbeitskorb 40 zum Einsteigen neben der Brüstung 214 positioniert ist.In Fig. 2c the chassis 10 is positioned in the position provided for the operation of the arm jib alongside the parapet 214 between the pillars 212. The horizontal pivot arm 20 is aligned at 90 ° querab to the longitudinal axis of the chassis 10 and thus protrudes maximally in the air space 206. The arm boom 30 is positioned in the air space 206 near the parapet 214 and still aligned parallel thereto so that the work basket 40 is also positioned for boarding beside the parapet 214.

Ausgehend aus dieser Stellung kann der in Fig. 5 mit der Kurve 104 dargestellte Arbeitsraum erreicht werden.Starting from this position, the in Fig. 5 achieved with the curve 104 shown working space.

Die Kurve 103 gibt den Arbeitsraum an, der bei einem in Transportstellung befindlichen Horizontalschwenkarm 20 mit dem Armausleger 30 zu erreichen ist, beispielsweise wenn die Hubarbeitsbühne 100 im Außenbereich eingesetzt wird, wo es nicht erforderlich ist, über eine Brüstung 214 hinweg zu wirken.The curve 103 indicates the working space, which can be reached with a horizontal pivoting arm 20 located in the transport position with the arm boom 30, for example when the aerial work platform 100 is used outdoors, where it is not necessary to work across a parapet 214.

Das Kippmoment, das durch den über die Brüstung 214 auskragenden Horizontalschwenkarms 20 mit Armausleger 30 und Arbeitskorb 40 an der vordersten Stützstelle, also der brüstungsnahen Gleiskette, hervorgerufen wird, wird allein durch das Eigengewicht des Fahrgestells 10 kompensiert. Um die Standsicherheit im Betrieb zu gewährleisten, ist im Arbeitsraum 104 der Schwenkbereich des Horizontalschwenkarms 20 an der ersten Drehachse 21 in Bezug auf die Fahrgestelllängsachse auf etwa +100°, begrenzt.The tilting moment, which is caused by the horizontal pivoting arm 20 projecting beyond the parapet 214 with arm extension 30 and work cage 40 at the foremost support point, that is to say the crawler-type crawler, is compensated solely by the weight of the chassis 10. In order to ensure stability during operation, in the working space 104, the pivoting range of the Horizontalschwenkarms 20 at the first axis of rotation 21 with respect to the chassis longitudinal axis to about + 100 °, limited.

In Bezug auf die Längsachse des Horizontalschwenkarms 20 kann der Armausleger 30 dabei in allen Lagen des Horizontalschwenkarms 20 um die zweite Drehachse von etwa +110° bis -15° rotiert werden. Damit ist es möglich, wie Fig. 1 zeigt, bei üblichen Abmessungen von Arkadengebäuden 200 die Mitte der Glaskuppel 202 und die oberhalb der Hubarbeitsbühne liegenden Seitenfenster 204 zu erreichen. Die Hubarbeitsbühne 100 muss dann auf einen gegenüber liegenden Galeriegang 211 transportiert werden, um die andere Hälfte des Gebäudes abzuarbeiten.With respect to the longitudinal axis of the horizontal pivot arm 20, the arm extension 30 can be rotated in all positions of the horizontal pivot arm 20 about the second axis of rotation of approximately + 110 ° to -15 °. This makes it possible, how Fig. 1 shows, with conventional dimensions of arcade buildings 200, the center of the glass dome 202 and the side window 204 located above the working platform reach. The aerial work platform 100 must then be transported to an opposite gallery aisle 211 to work off the other half of the building.

In der Transportstellung, in der der Arbeitskorb 40 ohne Verkehrslast ist und der Armausleger 30 maximal eingezogen ist, können die oben genannten Drehwinkelbegrenzungen durch steuerungstechnische Maßnahmen aufgehoben werden.In the transport position, in which the work basket 40 without traffic load and the arm boom 30 is retracted to the maximum, the above-mentioned rotation angle limits can be canceled by control measures.

Ist eines der Teleskopelemente 31 ... 33 eingeschoben, so ergibt sich ein erweiterter Arbeitsraum, der durch die Kurven 103' und 104' in Fig. 6 dargestellt ist. Durch das geringere Kippmoment des verkürzten Armauslegers 30 kann nun zugelassen werden, den Horizontalschwenkarm 20 um bis zu +160° von der Fahrgestelllängsachse weg zu bewegen und Armausleger 30 gegenüber dem Horizontalschwenkarm 20 um ca. ± 85° zu verschwenken. Damit ergibt sich im Luftraum jenseits der Brüstung 214 ein Arbeitssektor des Armauslegers 30 von ca. 65°, bezogen auf die Längsachse der Brüstung 214 bzw. die Fahrgestelllängsachse.If one of the telescopic elements 31 ... 33 is inserted, the result is an extended working space, which is defined by the curves 103 'and 104' in FIG Fig. 6 is shown. Due to the lower overturning moment of the shortened arm jib 30, it is now possible to allow the horizontal pivot arm 20 to be moved up to + 160 ° to move away from the chassis longitudinal axis and pivot arm arm 30 relative to the horizontal pivot arm 20 by about ± 85 °. This results in the airspace beyond the parapet 214, a working sector of the arm jib 30 of about 65 °, based on the longitudinal axis of the parapet 214 and the chassis longitudinal axis.
