Understand the working principle of electric winch

The electric disk drives the motor from the battery of the car, and then the motor drives the drum to rotate. The drum drives the driving shaft, and the driving shaft drives the planetary gear to generate strong torque. The moment is then transmitted back to the drum, which drives the winch. There is a clutch between the motor and the reducer, ATV/UTV Winch can be switched by a handle. The brake unit is in the drum, which locks automatically when the winch is tightened.


The power of winch motor is very small, only 3-4kw at most, but it can be transformed into powerful force through reducer. Most winches use planetary gears as reducers, which have the advantages of relatively large reduction ratio due to small volume, more contact points of gears and longer service life. Winches are usually installed in a smaller space, the smaller the lighter the better. Planetary gears can not only meet this requirement, but also produce large reduction ratio.


The pulling force of the winch is directly related to the length of the winch. When the winch is just pulled, the force is the largest, and then the tension will be reduced for each turn of the winch. The longer the rope is pulled, the weaker the pull. In practical application, some auxiliary items are necessary for safe and smooth use of winch, such as gloves to protect hands. In addition, if you want to fix the winch on a tree, you need a belt, a U shaped lifting eye and a tightening pulley
