[0003] The existing electric hoist trolley operating device includes a trolley frame, support tube, drive shaft, operating motor, and wheels. The support tube mainly connects the trolley frame and reduces deformation. Because the support tube connects the two ends of the trolley frame and bears the weight, the trolley frame support tube is difficult to assemble and position, and it will move and rotate axially after assembly, causing the support tube and the trolley frame to wear easily, causing the trolley frame to deform to both sides, affecting the use of the electric hoist. During use, the working conditions and loads vary greatly. The hoist is basically installed on a traveling frame several to more than ten meters above the ground. The worn support tube will form a V-shaped deformation, which will create a series of safety hazards. Utility Model Content
