snatch block will double your load capacity

If you want to double motor winch, or if the anchor point is too close to let out enough cable for a strong pull, use a snatch block to double the line. Using a snatch block will double your load capacity and will allow you to spool out more cable to reach the maximum rating of your winch. For even more power, you can rig up a triple line pull. However, use caution with double and triple lines. As the strength of the pull increases, so does the amount of stress placed on each rigging point. Make sure your anchor point is rock solid and can withstand the force of the pull.
As your winch works harder, it generates more heat. In order to prevent overheating the motor, take breaks if you're pulling over a long distance and let the motor cool before starting again. Winching places a heavy load on your electrical system, so keep your engine running to prevent a complete drain. In some cases, a stock battery may not provide enough juice to power a maximum pull. Some wheelers swap the stock battery for a heavy duty one, or they install a second battery solely for recovery.
