Electric winches can be used to rescue other vehicles

Electric winches utilise an electric motor connected directly to your cars battery. The motor is heavily geared to provide a large amount of torque at a relatively slow speed.
An electric winch will have a large drum which either a steel or synthetic cable is wound. Winches feature a hand controller which allows you to operate the winch at a safe distance in case the winch rope breaks.
The heavy duty synthetic rope winch is attached via a shackle or hook to an anchor point. The winch is then operated by the hand controller to pull the vehicle free of the bog.
Winches can be used to rescue other vehicles by straight pulling the vehicle free, or used with a snatch block and anchor point to pull a stuck vehicle in a number of different ways.
