Jul 15, 1998 · These are a pain to use but are cheap and work. I think I have three or four now. These are great for getting that 2 ton hoist hung. . . I bought an overhead crane at an auction for the steel. It had two hoists and trolleys on it, an old manual 2 ton "Tri-plex" and a little 1 ton electric. The electric is three phase and I have never set it up.
