Abstract
The invention discloses a composite lifting device which comprises a movable platform trolley, a supporting plate, a shear fork lifting frame, a hydraulic pump, a jacking hydraulic cylinder and a vertical frame. The shear fork lifting frame is arranged on the supporting plate. The hydraulic pump is arranged on one side of the shear fork lifting frame. The vertical frame is vertically arranged on the movable platform trolley. The jacking hydraulic cylinder is arranged in the vertical frame. One end of the supporting plate is provided with an L-shaped folded plate. The L-shaped folded plate comprises a top flat plate body and a vertical plate body, wherein the side face of the vertical plate body is connected with the supporting plate, and the top flat plate body is connected with the top end of a telescopic rod of the jacking hydraulic cylinder. A first hydraulic control valve is arranged on the hydraulic pump. In this way, the height of the shear fork lifting frame is increased by means of the jacking hydraulic cylinder and the supporting plate, the lifting distance of the device is increased, and the composite lifting device is high in stability, large in bearing capacity and convenient to move.
