The invention discloses a light crane telescopic hard arm clamp which comprises a telescopic pipe, one end of the telescopic pipe is connected with a main beam trolley, the other end of the telescopic pipe is provided with a clamp assembly and an electric hoist, the electric hoist is located above one end of the telescopic pipe, and a chain of the electric hoist penetrates through the telescopic pipe to be connected with the clamp assembly. The light crane telescopic hard arm clamp can pull the clamp assembly and contract the telescopic pipe and the driving support, one end of the driving support is rotationally connected with one end of the telescopic pipe, the other end of the driving support is provided with a driving wheel and a driving motor, and the elastic assembly is arranged on the driving support. The gap between the driving wheel and the rail is compensated through the connecting rod and the compression spring, the driving wheel is kept in close contact with the rail, meanwhile, the vibration gap is compensated through deformation of the compressed spring, and the driving wheel is prevented from being separated from the rail.

    本发明公开了轻型起重机伸缩硬臂夹具,包括:伸缩管,伸缩管的一端与主梁小车连接,伸缩管的另一端设置有夹具组件,电动葫芦,电动葫芦位于伸缩管的一端的上方,电动葫芦的链条穿过伸缩管与夹具组件连接,能够拉动夹具组件并收缩伸缩管,驱动支架,驱动支架的一端与伸缩管的一端转动连接,驱动支架的另一端设置有驱动轮和驱动电机,弹性组件设置在驱动支架上,该轻型起重机伸缩硬臂夹具,通过伸缩管提供刚性连接增加起重机的稳定性,通过连接杆和压缩弹簧补偿驱动轮与轨道间隙,使驱动轮保持与轨道的紧密接触,同时利用压缩的弹簧的形变补偿震动间隙,避免驱动轮与轨道分离。
