I've gotten to old to lift my folding trailer up onto the casters easily anymore. I installed this hoist onto a rail lagged to the rafters. With careful positioning, I can easily lift or safely lower the trailer now. I set it up 2 to 1, it would be really fast running 1 to 1. I will probably get a trolly for the rail because the hoist's wire angle changes so much from the beginning of the hoist until it's all the way up. It's a backsaver and makes it safer to lift and lower the trailer now. And yes, I need to put an electric outlet up there and get rid of the extension cord.
