What size winch do I really need?

Recommended Posts

Installing in a 24’ enclosed trailer. I don’t expect to drag in anything that is not rolling but you never know.

Considering the "but you never know" factor, go for the largest capacity winch that your trailer space and structure and your wallet will support.

Based on the weight of your rolling load and the slope of your trailer's ramps, you can find the minimum winch to do the job. But you should also remember that winches are rated based on the first layer of rope, where they have the greatest power. In practice, your winch will probably have more than 1 layer of rope on the drum when it is working and will be pulling at less than its maximum. Winches lose from 13% 25% of their pulling power with each wrap of rope on the winch drum. Because of this, etrailer.com recommends using a winch with a line pull capacity equal to that of the load being moved. You can increase the pulling power of a winch by using a pulley block. A pulley block can nearly double the winch's capacity by simply attaching the pulley block's hook directly to the load and the winch's hook to a sturdy mount near the winch.
