The invention relates to the technical field of winch lifting, and discloses a winch lifting device which comprises a movable frame capable of being hung on a trailer and a telescopic frame arranged on the frame. A telescopic frame lifting mechanism is arranged on the front face of the telescopic frame, and a building material lifting mechanism is arranged on the back face of the telescopic frame. The telescopic frame comprises a first ladder frame, a second ladder frame and a third ladder frame, and the lower end of the first ladder frame is rotationally connected to the frame through a hinge seat; grooves are formed in the inner side faces of the first ladder frame, the second ladder frame and the third ladder frame, the first ladder frame is inserted into the groove of the first ladder frame in a sliding mode, and the third ladder frame is inserted into the groove of the second ladder frame in a sliding mode. According to the lifting device of the winch, through the arrangement of the telescopic steel wire rope and the fixed-length steel wire rope, the telescopic frame composed of the multiple sections of ladder assemblies can freely ascend and descend under the operation of the telescopic winch motor, building materials can be conveniently lifted to different heights, and the applicability of the lifting device is improved.
