Definitions

  • the invention relates to a support device for loading cranes or the like which can be attached to a vehicle, with a support frame for the loading crane and with the front and rear ends of the support frame connected, pull-out front and side pull-out rear floor supports.
  • Support devices of this type serve to enlarge the support base of the cranes in the case of loading cranes mounted on vehicles.
  • a support device for loading cranes or the like known with front and rear floor supports.
  • the front floor supports are arranged in telescopically pull-out guides arranged on a vehicle frame in a horizontal plane.
  • the rear floor supports are arranged laterally telescopically in guides arranged at the end of the vehicle frame. Due to the geometric dimensions of the vehicle frame, the support base and thus the crane size is limited.
  • the object of the invention is to enable the construction of loading cranes on commercial vehicles in which there is a large ratio of crane size to vehicle size.
  • the support frame has two spaced and approximately parallel longitudinal beams, which are connected by transverse struts on their underside for receiving the loading crane, and that a longitudinal strut which can be pulled out in the longitudinal direction of the longitudinal beam is connected to each longitudinal beam , which are firmly connected at their rear ends by a cross member, on which the rear floor supports are arranged so that they can be pulled out laterally.
  • This design allows the support base to be considerably enlarged in relation to the vehicle size by pulling out the longitudinal struts. Furthermore, the connection of the longitudinal beams by means of cross struts and the connection of the longitudinal beams by means of cross beams to one another creates a support frame of high load-bearing capacity, so that very large loading cranes can also be used in relation to the size of the vehicle.
  • the front floor supports are advantageously connected to swivel arms which are articulated on the front ends of the side members.
  • the swivel arms are preferably articulated on the underside of the side members.
  • the longitudinal beams are hollow on the inside and the longitudinal struts are slidably mounted inside the longitudinal beams.
  • the cross member preferably consists of two interconnected pipes or the like, in which the rear floor supports are mounted so that they can be pulled out laterally.
  • the swivel arms are preferably hollow on the inside and the front floor supports are slidably mounted inside the swivel arms.
  • a support device with a support frame is arranged on a commercial vehicle (1), which has two longitudinal beams (2) and (3) which are spaced apart and parallel to one another.
  • 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 slidably mounted in each longitudinal member (2) and (3).
  • the longitudinal struts (6) and (7) are firmly connected at their rear end by a cross member (8) made of two internally hollow tubes (9) and (10) connected to one another.
  • rear floor supports (11) and (12) which can be pulled out laterally are slidably mounted in the tubes (9) and (10).
  • 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.
  • 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 longitudinal members (2) and (3) and the arrangement of the cross struts (4) also under the longitudinal struts (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.
