I have an old chain hoist. Big chain hoist. Have a steel I bean garage. It lifted a very big lathe. I would reinforce the rafters of barn and hoist it off trailer.
If you live close to Terre Haute, I'll let you use the old chain hoist. I think it's rated at 4000 lb. You pull and pull on the chain at get it to lift a little.
Left my email open if interested in my offer.
