Winch principle and characteristics
- Sep 03, 2018 -


Simply put, the working mechanism inside the winch is: the electric power from the car first drives the motor, 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 torque is then transmitted back to the drum, which drives the winch. There is a clutch between the motor and the reducer that can be switched by a handle. The brake unit is inside the drum and the drum is automatically locked when the cable is tightened.

In practical use, some auxiliary items are essential for safe and smooth use of the winch, such as gloves can safely protect the hands. In addition, if the winch is to be fixed to a tree, a strap, a u-shaped lifting lug and a tight pulley are required. The strap is used to fix the fulcrum. Its ideal length is 1.5 to 2 meters; the u-shaped lifting lugs connect the hooks to the belt and the winch. Therefore, it is best to prepare several sizes of lifting lugs; when using double or triple lines, when changing the drag direction, you need a tight line pulley.


1. The traction force of the winch is fixed in pounds and can be converted into tons or kilograms by conversion. It is best to choose a winch with a high number of pounds because the weight of the trapped vehicle is often much higher than the daily weight. Do not pull objects that exceed the traction of the winch.

2. The more the number of turns of the cable of the winch wound on the reel, the smaller the pulling force of the outer ring. The long reel of the reel can reduce the number of turns of the winding to increase the traction of the outer ring. For the same winch, the shorter outer cable has a longer outer ring traction.
