DE3635328A1 - VEHICLE SUPPORTING DEVICE FOR LOADING CRANES OR THE LIKE - Google Patents

Description

The invention relates to a mountable on a vehicle Support device for loading cranes or the like, with a support frame for the loading crane and with with the front and rear ends of the support frame connected, pull-out front and rear floor supports.

Such support devices are used in vehicles erected loading cranes to enlarge the support base of the cranes.

The object of the invention is to build To enable loading cranes on commercial vehicles where a there is a large ratio of crane size to vehicle size.

This object is achieved in that the support frame two spaced and approximately parallel to each other Has longitudinal beams, which by lying on its underside Cross struts are connected to accommodate the loading crane, and that with each side member in the longitudinal direction of the Longitudinal strut connected to the rear pull-out strut is fixed at its rear ends by a cross member are connected to each other on the rear floor supports are arranged laterally extractable.

The front floor supports can advantageously be pulled out connected with swivel arms at the front ends of the  Side members are articulated. The swivel arms are preferably hinged to the underside of the side members.

In an advantageous embodiment, the side members are hollow inside and are the longitudinal struts inside the Side member slidably mounted.

The cross member preferably consists of two together connected pipes or the like, in which the rear floor supports are mounted laterally extractable.

The swivel arms are preferably hollow on the inside and are Front floor supports can be moved inside the swivel arms stored.

The invention is illustrated by way of example in the drawings. Show it:

Fig. 1 is a utility vehicle with support means and loading crane in side view in the traveling state,

Fig. 2 shows the commercial vehicle of FIG. 1 in plan view and

Fig. 3 shows the commercial vehicle with a support device with extended floor supports.

According to FIGS. 1 to 3, a support device with a support frame is arranged on a commercial vehicle ( 1 ), which has two longitudinal beams ( 2 ) and ( 3 ) running at a distance and parallel to each other. The longitudinal beams ( 2 ) and ( 3 ) are connected to one another on their underside by cross struts ( 4 ) on which a loading crane ( 5 ) is rotatably arranged.

The side members ( 2 ) and ( 3 ) are hollow on the inside as a box section. A longitudinal strut ( 6 ) or ( 7 ) ( FIG. 3), which can be pulled out backwards in the longitudinal direction of the carrier, is mounted displaceably in each longitudinal member ( 2 ) and ( 3 ). The longitudinal struts ( 6 ) and ( 7 ) are firmly connected to each other at their rear end by a cross member ( 8 ) made of two internally hollow tubes ( 9 ) and ( 10 ) connected to one another.

As shown particularly in Fig. 3, are slidably mounted in the tubes (9) and (10), laterally extractable rear ground supports (11) and (12).

Swivel arms ( 13 ) and ( 14 ) are pivotally connected to the front ends of the side members on the underside of the side members. The swivel arms ( 13 ) and ( 14 ) are also hollow on the inside. The front floor supports ( 15 ) and ( 16 ) are mounted in them so that they can be pulled out.

The longitudinal struts ( 6 ) and ( 7 ) and the floor supports ( 11 ), ( 12 ), ( 15 ) and ( 16 ) can either be pulled out or swung out by hand. It is also possible to provide auxiliary equipment.

The support base of the support device is considerably enlarged by the longitudinal struts ( 6 ) and ( 7 ) which can be pulled out to the rear and which are connected to one another at their rear ends. In addition, the connection of the longitudinal struts ( 6 ) and ( 7 ) through the cross member ( 8 ) increases the load capacity of the support device.

The arrangement of the swivel arms ( 13 ) and ( 14 ) with the floor supports ( 15 ) and ( 16 ) under the side members ( 2 ) and ( 3 ) and the arrangement of the cross struts ( 4 ) also under the side members ( 2 ) and ( 3 ) enables the loading crane ( 5 ) to be arranged between the longitudinal beams ( 2 ) and ( 3 ), so that the support device has only a very small overall height.
