not sure for your application. I used three I-beams 10-11 inch...2 uprights and 1 across. Trolly hanging off the one horizontal beam. I use it to lift 1000lb bag of deer feed out of my truck bed. Uprights bolted to concrete floor. Works like a charm, I can unload truck in 10 minutes by myself. Harbor Freight 2 ton hoist and HF trollies.

how much are you lifting????

I've spent most of the money I've made in my lifetime on hunting and fishing. The rest I just wasted.....
