The relay transmission receives signals from the remote control, and the inside is a complete circuit that can change the direction of the motor.
There is a DC motor in this part. The winch model shown in the figure has a cooling fan that prevents the winch from overheating.
3. Noose guide
If you need to use a noose to work at an angle, this guide can lead the noose directly to the drum. If you have a roller, it is called a roller noose guide.
4. Cable drum
The cable drum is driven by an electric motor like a cylinder wound with a sling. The direction can be changed by the remote control button. The winch of the heavy winch is heavier and therefore the drum is larger.
The clutch is responsible for switching the cable drum. It is controlled by a simple handle.
6. Remote control
This remote control allows you to control the noose from a distance. Shown here is the most common model with a wire connected to the winch. There are also wireless remote controls on the market.
