rhino hand winch is available for the entire length of lift or pull

As your rhino hand 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.
double motor winch use two drums that require a "loop" of cable. Cable is continuously spooled in and out on the drum system. Because it does not accumulate on a drum you have an unlimited lifting or pulling distance. Also, the maximum force of the winch is available for the entire length of lift or pull. The drawback to using a double drum winch is that it requires at least one return pulley to complete the loop.
