Wrecker
The invention relates to a wrecker. The wrecker comprises a bodywork platform and a lifting device arranged on the bodywork platform, and the lifting device comprises a supporting arm, wherein the bottom of the supporting arm is hinged to the bodywork platform; a supporting arm connecting base is hinged to the supporting arm, wherein the rotating axis of the supporting arm connecting base is parallel to the swing axis of the supporting arm; a supporting arm drive lead screw is arranged on the bodywork platform in a swing mode, wherein the swing axis of the supporting arm drive lead screw is parallel to the swing axis of the supporting arm; a threaded transmission structure in threaded transmission fit with the supporting arm drive lead screw is arranged on the supporting arm connecting base. By means of the match of the supporting arm connecting base and the supporting arm drive lead screw, the swing angle of the supporting arm is determined by the length of the supporting arm drive lead screw, compared with a hydraulic cylinder with the limited using length in the prior art, the supporting arm can be driven to achieve swing at the larger angle to achieve a larger operation range, and the wrecker is high in adaptive capacity.
