Electric hoist is a device that transports by changing the potential energy, and has the characteristics of high power and strong lifting ability. The electric hoist mainly consists of two parts: a power device and a bracket.

　　The power device consists of an electric motor, designed with a mechanism for braking upon power failure. The motor is also equipped with a thermal switch to prevent overheating and burning of the motor; The reducer is a two-stage gear reduction, fixedly connected to the motor; The clutch, brake, and rope barrel are integrated, but when the clutch is in a disengaged state, it can achieve rapid descent. Operating the brake can control the descent speed to avoid impact. The circular hole on the front of the power unit casing can be used to install a blower, and users can equip a blower for forced cooling as needed. The housing itself comes with a toolbox, which contains a clutch handle, a special wrench with a brake handle, a jack nut washer, a top cap, a button starter, a travel switch, wires, and instructions.

　　The support part consists of a main rod and a rotating arm composed of a screw, a jack nut, and a vertical rod. The rotating arm can rotate 360 degrees on the main pole, and a travel switch is installed at the end of the arm to prevent lifting accidents caused by operational errors or button failure. By operating the button starter to achieve positive and negative rotation of the motor, the steel wire rope can be wound and released, and the lifting operation can be completed by lifting and lowering objects through some pulleys on the bracket.
