The invention relates to a crane drive device. The crane drive device comprises a walking end beam, a drive motor and a reduction box. The reduction box comprises a reduction gearbox. A torsion support is arranged at one end of the reduction gearbox. The bottom end of the reduction gearbox is connected with an output shaft with a spline at the end. An oil pump is arranged on the lateral face of the reduction gearbox and provided with an oil inlet pipe and an oil outlet pipe. The oil outlet pipe is connected with a cooling tank. Cooling tube nests are arranged on the upper portion of the cooling tank. Cooling ribs A are arranged on the surfaces of the cooling tube nests in the longitudinal direction. The lower portions of the cooling tube nests are connected with an oil returning pipe. A water inlet pipe is arranged on the lower portion of the cooling tank and provided with a circulating water pump. The circulating water pump is connected with an air cooler through a water returning pipe. Cooling ribs B are arranged on the inner wall of the air cooler in the axial direction; a cavity is formed inside the air cooler; spiral spacing blocks are arranged in the cavity; a water outlet pipe is arranged on the upper portion of the air cooler; a draught fan is installed at one end of the air cooler. The crane drive device has the advantages of being simple in structure, reasonable in design, good in cooling effect, high in radiating efficiency and long in service life.
