The lifting motor, drum device, and reducer are arranged in series, with a circular or square appearance, and have vertical lifting and operation functions. The lifting speed is divided into single speed or double speed. The dual speed model is based on the single speed model and adds a set of slow drive devices composed of slow motors and reducers, with a speed ratio of 10:1 to fast. When the fast motor is working, the slow drive device does not move, and the electric hoist rises and falls quickly. When the slow motor is working, the main lifting motor cone rotor is driven to rotate by the slow driving device, and the electric hoist is lifted and lowered at a slow speed.
