Double-layer casting trolley

A double-layer casting trolley comprises an upper-layer frame and a lower-layer frame, a lifting mechanism and a winding drum are fixed on the upper-layer frame, two ends of the upper-layer frame are respectively connected with one lower-layer frame, the axial direction of the lower-layer frame is perpendicular to the axis of the upper-layer frame, two ends of the lower-layer frame are respectively provided with a group of wheels, and the wheels are wheels of the trolley. And the trolley can move conveniently. A fixed pulley block and a running motor are fixed on the lower-layer frame, and the running motor is connected with wheels. Compared with the prior art, the trolley has the technical effects that the trolley is provided with a two-layer structure, the winding drum is fixed on the upper-layer frame, the fixed pulley is fixed on the lower-layer frame, the load of the fixed pulley acts above the wheels, and the part does not pass through the upper-layer frame (similar to a trolley body), so that the safet
