The hoisting motor, drum device and reducer are arranged in series, the appearance is round or square, with vertical lifting and operation functions, and the lifting speed is divided into single speed or double speed. The two-speed type is based on the single-speed type, adding a set of slow drive device composed of a slow motor and a reducer, and its speed ratio with the fast is 10:1. When the fast motor works, the slow drive device does not move, and the electric hoist rises and falls quickly. When the slow motor is working, the conical rotor of the main lifting motor is rotated by the slow driving device, and the electric hoist is raised and lowered slowly.
