The invention relates to an electric hoist revolving crane. The electric hoist revolving crane comprises a shell, a winding drum, a motor, a speed reducer, a steel wire rope, a pulley and a hanging hook; the winding drum coaxially passes through the shell; the motor is connected with a side wall at the right end of the shell; the output shaft of the motor, supported by bearings, passes through a side wall at the right end of the winding drum; the speed reducer is connected with a side wall at the left end of the shell; the output shaft of the motor is parallelly or coaxially connected with the input shaft of the electric speed reducer; the input shaft and the output shaft perform speed-reduction transmission through multistage parallel shaft gears; and the transmission is stable, and rotation speed can be effectively reduced, and torques can be enlarged, and the requirements of use occasions of electric hoists can be further satisfied; sleeve connection portions of the left end of the input shaft and the left end of the output shaft are respectively provided with a frame sealing ring, and therefore, debris can be effectively prevented from entering the bearings, the service lives of the bearings can be prolonged, and the supporting stability of the bearings can be improved; after the motor drives the speed reducer, the speed reducer and the shell coaxially drive the outer wall of the winding drum, so that the winding drum can be driven to transmit winding and release through large torques, and the operation of the winding drum is stable and safe, and the prolonging of the service life of the whole unit can be benefitted.
