Winch Mechanics
Now that you’ve familiarized yourself with your Warn winch and its components,we can begin reviewing how it works. The major advantage of an electric-powered winch is that it can provide reliable service for intermittent utility and recreational use even while the vehicle’s engine is stalled — assuming, of course, that sufficient battery current is available. Your winch can operate at high current loads, and, for this reason, the control box uses a high current control system to safely handle the current flow.
It is important to understand that the longer the pull, the more heat that is created, just like a hot plate. Prolonged winching without cooling the winch motor will damage the motor. Also, if the engine is idling during winching, the battery may drain faster than it is
charging. So pay close attention to your voltage gauge to make sure you aren’t draining your battery too low to start your vehicle.
The winch is controlled by the handheld remote control to allow the operator to stand clear while controlling the winching process. The remote control provides control of the forward or reverse rotation of the spooling drum.
How the Winch Reacts to Load
Warn winches are rated by pulling capacity. The maximum pulling capacity occurs on the first layer of wire rope on the drum. As the layers increase, the pulling power decreases. It’s the mathematics of winching. Exceeding the winch capacity could cause the winch to fail or the wire rope to break. Thinking through how you intend to use your winch now, could save you a big headache later.
