The invention discloses a wear-resistant supporting column for a crane, and belongs to the technical field of cranes. The wear-resistant supporting column comprises a shell, a control switch is fixedly mounted at the right end of the outer side of the shell, electric telescopic columns A are fixedly mounted on the inner side of the shell, the number of the electric telescopic columns A is two sets, electric telescopic columns B are slidably connected to the inner sides of the electric telescopic columns A, and through holes are formed in the top of the inner side of the shell. Grooves are formed in the electric telescopic columns A, rolling wheels are rotationally connected in the grooves, when the electric telescopic columns B are inserted into the electric telescopic columns A, gaps exist between the electric telescopic columns B and the inner walls of the electric telescopic columns A, when the electric telescopic columns B move in the axial direction of the electric telescopic columns A, the rolling wheels are attached to the outer walls of the electric telescopic columns B to rotate, the friction resistance of the electric telescopic columns B entering the electric telescopic columns A is reduced, and wear caused by friction between the electric telescopic columns A and the electric telescopic columns B is avoided.

    本发明公开了一种起重机用耐损耗支撑柱,属于起重机技术领域,包括壳体,所述壳体外侧右端固定安装有控制开关,所述壳体内侧固定安装有电动伸缩柱A,且电动伸缩柱A为两组,所述电动伸缩柱A内侧滑动连接有电动伸缩柱B,所述壳体内侧顶部开设有通孔,通过在电动伸缩柱A内开设有凹槽,凹槽内转动连接有滚轮,在电动伸缩柱B插入电动伸缩柱A内时,与电动伸缩柱A内壁存有间隙,并且当电动伸缩柱B沿着电动伸缩柱A轴向移动时,滚轮贴合电动伸缩柱B的外壁转动,减小电动伸缩柱B进入至电动伸缩柱A内的摩擦阻力,并且避免电动伸缩柱A与电动伸缩柱B之间摩擦而发生磨损。
