The electric single-beam crane comprises a supporting column and an electric hoist, an adjusting mechanism is arranged at the upper end of the supporting column and comprises a fixing rod fixedly arranged at the upper end of the supporting column, a sliding groove is formed in the front end of the fixing rod, and a limiting hole is formed in the side, close to the sliding groove, of the front end of the fixing rod; a movable frame is slidably arranged on the outer side of the fixed rod, and a linkage frame is slidably arranged on the outer side, close to the upper portion of the movable frame, of the fixed rod. According to the electric single-beam crane, the movable frame is pulled to slide along the fixed rod, and the linkage frame drives the linkage rod to slide in the inner side of the sliding groove, so that the movable frame drives the electric hoist to move to achieve the purpose of conveniently changing the ground clearance of the electric hoist, and the running time of the electric hoist is shortened; therefore, the working efficiency of workers is improved.

    本发明公开了一种电动单梁起重机,包括支撑柱、电动葫芦,所述支撑柱的上端设置有调节机构,所述调节机构包括固定设置在支撑柱上端的固定杆,所述固定杆的前端开设有滑动槽,所述固定杆的前端靠近滑动槽的一侧开设有限定孔,所述固定杆的外侧滑动设置有移动架,所述固定杆的外侧靠近移动架的上次滑动设置有连动架。本发明所述的一种电动单梁起重机,通过拉动移动架沿着固定杆滑动且使连动架带动连动杆在滑动槽的内侧中滑动从而使移动架带动电动葫芦移动达到便于改变电动葫芦的离地高度的目的,从而减少电动葫芦的运转时间,故而提高工人工作效率。
