Abstract

Provided is a swing arm device. The device comprises a frame mechanism, a swing arm disposed on the frame mechanism, a ground flat board movably connected to the swing arm and a swing arm tilting oilcylinder used for pushing the swing arm to rotate in order to drive the ground flat board to move. A rotary fulcrum of the swing arm is connected with the frame mechanism. With the swing arm device, insufficient obstacle removal is avoided by preventing the failure of an existing flat board to completely touch the ground. The swing arm device is safe and convenient to operate. The flat board can be controlled to wholly place on the ground. The included angle between the flat board and the ground is basically eliminated. Therefore, all kinds of vehicles can be moved to the flat board very conveniently. The swing arm device is reasonable and ingenious in design, convenient in obstacle removal, broad in application scope and high in practicality and is safe and reliable.

Description

technical field [0001] The invention relates to the field of wreckers, high-altitude operating vehicles and truck-mounted cranes, in particular to a swing arm device. Background technique [0002] Wreckers, aerial work vehicles and truck-mounted cranes need to move the working platform to the ground when performing operations. After the work is finished, the working platform is closed. The original working platform has a relatively large inclination angle to the ground when working, so during work, it is necessary to use a large force to drag objects to the working platform, and there are many inconveniences when performing operations. Contents of the invention [0003] The invention makes up for the deficiency of the existing slabs that cannot be completely dropped to the bottom (that is, half-grounded), provides a swing arm device, is convenient for operation, and expands the series of slab wreckers. [0004] The technical solution of the present invention is: comprisi...
