Electric winch is powered by motor. The power is input into the third level enclosed gear reduction box by flexible coupling to lift weight or pull by wire rope and to drive the drum from Low speed shaft end steel key. We use common motor when we need to lift or pull small weight. Conversely, lifting motor is adapted. The common motor can start directly. But the lifting motor starts slowly and stably by cam switch and resistance adjusting. The brake system adopts electromagnetic braking or hydraulic braking.
high speed winches work principle
The winch transforms electric energy into mechanical energy through the motor1, which is rotor of the motor moves, outputs, and then through the brake 2, and the reducer 3 reduces speed to rotate the reel 4. The reel winds the wire rope and passes through pulley block to make the hook lift the load Q, and transforms mechanical energy into mechanical work finishing transportation, load and unload of heavy weights.
