Definitions

  • the invention relates to a vehicle crane consisting of a vehicle with chassis and attached supports, which can be moved from a folded transport position into a deployed working position, a revolving stage and a buildable on the revolving crane structure.
  • a crane will be in the DE-U-94 12 217 and the DE-A-2 017 058 disclosed.
  • a vehicle crane While usually a vehicle crane consists of a vehicle with fixed rotating platform and built on the turntable telescopic boom, it is already known in large vehicle cranes, which are designed as a lattice or telescopic crane to separate the lattice or Telekranteil from the rest of the vehicle to be able to meet the maximum axle loads of 12 t during transport. Only at the construction site in use, the grid or Telekranteil, which is transported separately to the place of use, mounted. Such previously known large vehicle cranes therefore consist of a vehicle with attached supports that can be moved from a folded transport position to a deployed working position and a revolving stage.
  • the object of the invention is to increase the crane size, taking into account the maximum axle load of 12 t and the legally permissible total height even further.
  • a vehicle crane with the combination of the features of claim 1.
  • a vehicle crane which consists of a vehicle with chassis and attached supports that are movable from a folded transport position into a deployed working position, a revolving stage and a buildable on the revolving crane structure, the chassis with supports designed such that this maximum permissible height in the transport state, for example, the permissible height of 4m, fully exploit.
  • a larger support base can be selected, whereby the crane can lift very high loads with comparatively low ballast.
  • This reduction of the necessary ballast leads to great advantages, especially in rapidly changing locations.
  • the weight of the ballast to be transported can be reduced, so that also here the transport costs can be reduced.
  • the revolving stage is detachably coupled to the vehicle so that it can be separated from the vehicle for road transport. This ensures that the height of the revolving stage does not take up even a part of the vehicle height, so that the attached supports, which can be moved from a folded transport position to a deployed working position, can fully exploit the maximum permissible height in the transport state.
  • the vehicle has four supports pivotally mounted on its chassis. These four supports can be pivotable via piston-cylinder arrangements.
  • the four supports are telescopic in length, so that the support base can be further increased.
  • the articulation points of the supports are arranged in the central region of the chassis, wherein the free ends of the supports are aligned in the transport position respectively in the direction of the driver's cab or the vehicle rear.
  • the rear supports are not only pivotable in a transport and working position, but also in a position between these two end positions in which the support base of the crane to the rear - especially when erecting the boom - can be improved. This results in erecting the boom a very high stall torque. After complete erection of the boom then the supports can be further pivoted into a working position, so that a uniform support in a 360 ° pivoting range is ensured here.
  • the supports In the transport position, the supports can essentially occupy the space between the chassis and the overall height of the vehicle.
  • the revolving stage can be connected to the vehicle with a quick connection.
  • a fast construction and removal of the revolving stages is possible.
  • FIG. 1 10 is a vehicle crane according to an embodiment of the present invention.
  • the vehicle crane consists of a vehicle 12 with in the representation according to FIG. 1 in working position unfolded supports 14, 16, 18 and 20.
  • the supports 14, 16, 18 and 20 are telescopic. They are each pivoted about hydraulic piston cylinder assemblies 22 from the transport position to a working position.
  • the mounted supports are supported in the transport position via hydraulically extendable outriggers 24 on the ground.
  • the vehicle crane 10 consists of a vehicle 12, which is designed as 8-axle. In front of the chassis with the eight axles a driver's cab 26 is arranged. Above the chassis with the eight axles, the supports 14, 16, 18 and 20 are pivoted in the central region of the vehicle 12. In the central region of the vehicle 12, a rotating crane 28 is arranged, on which a revolving stage 30 (see. FIG. 3 and FIG. 5 ) can be placed.
  • the legal total height for the vehicle is 12 4 m.
  • the hinged supports 14, 16, 18 and 20 are telescopic, wherein, as in the FIGS. 2, 3 and 4 shown, are formed box-shaped with a substantially rectangular cross-section.
  • the vehicle 12 moves without patch turntable and built-up crane structure to the site.
  • the revolving stage 30 optionally after previous assembly of attachments, such as catwalks 32 and a rise not shown here (see. FIG. 5 ) placed on the turntable 28.
  • the touchdown is done by a separate vehicle crane 50.
  • the vehicle crane takes the turntable 30 of a low loader. After appropriate driving away of the low loader, the large vehicle crane 10 is positioned at right angles to the vehicle crane 50 and the turntable 30 is lowered and connected via a quick connection or quick connection not shown here with the chassis frame.
  • the serving for mounting crane 50 positions its support under the folding spaces of the large vehicle crane 10.
  • the catwalks 32 and possibly other attachments such as a rise or the like can be connected via bolts with the turntable 30 before it is then placed together with these attachments on the large vehicle crane 10 and connected to this via the quick connection.
  • the crane body can then be bolted to the revolving stage.
  • the vehicle crane 10 Due to the high folding supports the vehicle crane 10 reaches a very high rigidity, so that much higher loads can be achieved.
