Description

Die Erfindung betrifft einen Fahrzeugkran nach dem Oberbegriff des Anspruchs 1.The invention relates to a vehicle crane according to the preamble of claim 1.

In üblicher Weise weist ein Fahrzeugkran einen Unterwagen und einen Oberwagen, sowie einen Drehkranz und einen Ausleger auf. Der Oberwagen ist über den Drehkranz gegenüber dem Unterwagen verdrehbar. Auf dem Oberwagen ist der in der Regel teleskopierbar ausgestaltete Ausleger um einen Drehpunkt verschwenkbar angeordnet. Der Oberwagen trägt darüber hinaus eine Winde, auf die das Hubseil aufwickelbar ist.In the usual way, a vehicle crane on an undercarriage and a superstructure, and a turntable and a boom. The superstructure is rotatable over the turntable opposite the undercarriage. On the upper carriage of the usually telescopically designed boom is pivotally mounted about a pivot point. The superstructure also carries a winch on which the hoist rope can be wound up.

Ein Fahrzeugkran nach dem Stand der Technik ist beispielhaft in Fig. 1 dargestellt. Der dort dargestellte Fahrzeugkran 10 weist einen zweiachsigen Unterwagen 12 und einen mittels eines hier nicht näher dargestellten Drehkranzes auf diesem drehbar angeordneten Oberwagen 14 auf. Der Oberwagen 14 weist einen Teleskopausleger 16 auf, der um eine Schwenkachse 18 schwenkbar auf der Drehbühne 20 des Oberwagens 14 angeordnet ist. Im hier dargestellten Ausführungsbeispiel weist der Fahrzeugkran eine Fahrerkabine 22 und eine auf der Drehbühne des Oberwagens angeordnete Kranführerkabine 24 auf. Bei dem Fahrzeugkran nach dem Stand der Technik ist eine Hubseilwinde 26 hinter dem durch die Schwenkachse 18 gebildeten Drehpunkt des teleskopierbaren Auslegers angeordnet. Diese Anordnung der Winde 26 verlängert die Auslegerlänge im Transportzustand nach hinten. Das bedeutet, dass durch die Einbaulänge der Winde der Drehradius des Kranes vergrößert wird bzw. dass der Ausleger im Transportzustand vorne, im hier vorliegenden Fall also in Richtung der Fahrerkabine 22 vergleichsweise weit über das Fahrzeug übersteht.A vehicle crane according to the prior art is exemplary in Fig. 1 shown. The vehicle crane 10 shown there has a two-axle undercarriage 12 and a turntable not shown here on this rotatably mounted upper carriage 14. The uppercarriage 14 has a telescopic boom 16, which is arranged about a pivot axis 18 pivotally mounted on the revolving platform 20 of the upper carriage 14. In the exemplary embodiment illustrated here, the vehicle crane has a driver's cab 22 and a crane operator cab 24 arranged on the revolving platform of the superstructure. In the vehicle crane according to the prior art is a hoist winch 26 behind the through the Pivoting axis 18 formed pivot point of the telescopic boom. This arrangement of the winch 26 extends the boom length in the transport state to the rear. This means that the turning radius of the crane is increased by the installation length of the winch or that the boom in the transport state at the front, in the present case in the direction of the driver's cab 22 relatively far beyond the vehicle.

Aus der JP-A-07267583 ist ein Fahrzeugkran mit einem eine Drehbühne aufweisenden Oberwagen bekannt, an dem ein Ausleger um einen Drehpunkt verschwenkbar angeordnet ist. Am Ausleger selbst ist eine eigene Drehachse für zwei Umlenkrollen angeordnet, die jeweils seitlich über den Ausleger hinausgezogen ist, um dort seitlich vom Ausleger jeweils eine Umlenkrolle aufzunehmen. Unterhalb der Umlenkrollen ist im Bereich des Auslegers jeweils seitlich von diesem über einen eigens hierfür vorzusehenden Rahmen eine Winde für das Hubseil vorgesehen.From the JP-A-07267583 is a vehicle crane with a revolving stage having a superstructure on which a boom is pivotally mounted about a pivot point. On the boom itself a separate axis of rotation for two pulleys is arranged, which is laterally extended beyond the boom to take there laterally from the boom each have a pulley. Below the pulleys a winch for the hoist rope is provided in the region of the boom laterally of this over a specially provided for this purpose frame.

Das Dokument US-A- 3 620 579 zeigt einen Fahrzeugkran entspruchend dem Oberbegriff des Anspruchs 1.The document US-A-3,620,579 shows a vehicle crane entladend the preamble of claim 1.

Aufgabe der vorliegenden Erfindung ist es, einen Fahrzeugkran mit einem vergleichbar längeren Ausleger ausstatten zu können, ohne den Drehradius des Kranes bzw. den Überstand des Auslegers im Transportzustand zu vergrößern.Object of the present invention is to equip a vehicle crane with a comparatively longer boom, without increasing the radius of rotation of the crane or the projection of the boom in the transport state.

Erfindungsgemäß wird diese Aufgabe durch die Kombination der Merkmale des Anspruchs 1 gelöst. Erfindungsgemäß ist hier bei einem gattungsgemäßen Fahrzeugkran mit den Merkmalen des Oberbegriffs des Anspruchs 1 die Winde unterhalb des Anlenkpunkts des teleskopierbaren Auslegers in der Drehbühne angeordnet. Aufgrund dieser Anordnung kann der Ausleger um die Länge der Winde nach hinten versetzt werden, so dass der Ausleger selbst vergleichsweise weniger weit über das Fahrerhaus hinaussteht. Will man eine gleiche Gesamtfahrzeuglänge erzielen, so kann der auf der Drehbühne des Oberwagens aufgesetzte teleskopierbare Ausleger vergleichsweise länger ausgeführt werden.According to the invention this object is achieved by the combination of the features of claim 1. According to the invention here in a generic vehicle crane with the features of the preamble of claim 1, the winch below the pivot point of the telescopic boom in the turntable. Due to this arrangement, the boom can be offset by the length of the winch to the rear, so that the boom itself comparatively less far beyond the cab. If you want to achieve the same total vehicle length, so the patch on the turntable of the superstructure telescopic boom can be made comparatively longer.

Demnach ist das Hubseil über eine am Ausleger angeordnete Umlenkrolle geführt, die seitlich verschieblich auf der Schwenkachse des Teleauslegers angeordnet, wobei die Winde unterhalb des Schwenkachse in des Drehbühne gelagest ist.Accordingly, the hoist rope is guided over a deflection roller arranged on the boom, which is arranged laterally displaceable on the pivot axis of the Telebaler, wherein the winch is gelagest below the pivot axis in the turntable.

Weitere Merkmale, Einzelheiten und Vorteile der Erfindung ergeben sich aus einem in der Zeichnung dargestellten Ausführungsbeispiel.Further features, details and advantages of the invention will become apparent from an embodiment shown in the drawing.

Die Fig. 2 zeigt eine bevorzugte Ausgestaltung der Erfindung. Hier ist ein Fahrzeugkran 10 mit einem zweiachsigen Unterwagen 12 gezeigt. Auf dem Unterwagen 12 ist über einen hier nicht näher dargestellten Drehkranz eine Drehbühne 20 eines Oberwagens 14 gelagert. Der Unterwagen 12 weist eine Fahrerkabine 22 auf. Auf dem Oberwagen 14 ist eine Kranführerkabine 24 angeordnet.The Fig. 2 shows a preferred embodiment of the invention. Here, a vehicle crane 10 with a biaxial undercarriage 12 is shown. On the undercarriage 12, a revolving platform 20 of a superstructure 14 is mounted on a turntable, not shown here. The undercarriage 12 has a driver's cab 22. On the upper carriage 14, a crane cab 24 is arranged.

Ein zentraler Teil des Oberwagens ist der teleskopierbare Ausleger 16, der um eine Schwenkachse 18 schwenkbar ist. Die Schwenkachse 18 ist in der erfindungsgemäßen Ausgestaltung der Erfindung möglichst weit hinten in der Drehbühne 20 des Oberwagens 14 gelagert. Unterhalb dieser Schwenkachse 18 ist in der Drehbühne die Hubseilwinde 26 gelagert. Das Hubseil 26, das auf die Winde aufgewickelt und von dieser wieder abgewickelt werden kann, wird über ein Umlenkrad 28 geführt, welches seitlich verschiebbar auf der Schwenkachse 18 des teleskopierbaren Auslegers sitzt. Hierdurch wird eine besonders kompakte Bauweise ermöglicht. Dadurch, dass die Baulänge der Winde 26 nach unten in die Drehbühne verlagert ist, kann oberhalb dieser ein vergleichsweise längerer Ausleger 16 um die Schwenkachse 18 schwenkbar gelagert sein.A central part of the superstructure is the telescopic boom 16, which is pivotable about a pivot axis 18. The pivot axis 18 is mounted in the inventive embodiment of the invention as far back in the turntable 20 of the upper carriage 14. Below this pivot axis 18, the hoist winch 26 is mounted in the revolving stage. The hoist rope 26, which can be wound on the winch and unwound from this again, is guided via a guide wheel 28, which sits laterally displaceable on the pivot axis 18 of the telescopic boom. This allows a particularly compact design. Due to the fact that the overall length of the winch 26 is displaced downwards into the revolving platform, a comparatively longer boom 16 can be mounted pivotably about the pivot axis 18 above the latter.
