The invention discloses a crane hoisting mechanism, and relates to the technical field of hoisting mechanical equipment. The crane hoisting mechanism comprises a frame, a first winding drum, a secondwinding drum, a mooring rope, a first driving device, a second driving device, a chain, a wheel set and two chain wheels, the wheel set is mounted at the bottom of the frame, the first driving deviceis used for driving the wheel set to move, the first winding drum and the second winding drum are rotationally installed on the frame, one end of the first winding drum and one end of the second winding drum are each provided with the chain wheels, the chain is installed on the two chain wheels, the second driving device is used for driving the first winding drum and the second winding drum to rotate, and the diameter of the first winding drum is larger than that of the second winding drum, the cable is wound on the first winding drum and the second winding drum, and when the second winding drum unwinds the cable, the first winding drum winds the cable upwards, and when the second winding drum winds the cable upwards, the first winding drum unwinds the cable. According to the crane hoisting mechanism, cargos are driven to lift at a differential speed and are strictly limited, and the transmission lifting is stable, safe and reliable.
