Electrical Winches

Powered by a double-battery system, this will be very advantageous for you. Although it gets its power from the battery of the vehicle, it also gets power from a deep-cycle type of battery that operates on its own. Thus, this kind of winch will never affect your engine's function, radio, lights, etc.

Mechanical Winches

There are two types of mechanical winches. It can be either drum or capstan. The drum type's power is drawn from the car's engine carried to the winch through a shaft. This type tends to have greater power than electrical winches because it works well if and only if the car engine is working well. Meanwhile, capstan's power relies on the vehicle's engine still but is carried directly using a dog clutch locked in the crankshaft pulley. Just like the drum type, a capstan works while the engine is working. But to effectively put the capstan into use, you must have the necessary skills in using it. You must also choose the right rope with the right diameter so that the slip will be minimized and the rope won't get caught by itself for it will lead to a very dangerous consequence.
