I don't have anything like that out on that property. I do have some large logs and some steel beams that will span the with and some large logs. It can be jacked up using bottle jacks andd rested on the logs, you could then back the trailer under it then it could be lowered by jacks down onto the trailer. That's how it was put in place. I just don't have the jacks large enough to do it. I think it would take a mimimum of 2 4 ton jacks. Does that sound doable, or do you have another idea?
