Definitions

  • the invention relates to a vehicle crane according to the preamble of claim 1.
  • 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.
  • a vehicle crane according to the prior art is shown by way of example in FIG.
  • 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.
  • the vehicle crane has a driver's cab 22 and a crane operator cab 24 arranged on the revolving platform of the superstructure.
  • 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.
  • 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.
  • this object is achieved by the combination of the features 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.
  • the hoist rope is advantageously guided over a deflection roller arranged on the boom.
  • the deflection roller is arranged laterally displaceable on the pivot axis of the Teleausleger.
  • Fig. 2 shows a preferred embodiment of the invention.
  • a vehicle crane 10 with a biaxial undercarriage 12 is shown.
  • 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.
  • a crane cab 24 is arranged on the upper carriage 14.
  • 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.
