Had a similar problem in moving my Dursley from one location to another about 500" away, up a hill, into a building and onto a 10" high concrete pad. No tractor here either. I lifted it with wedges until i was able to get it onto s couple of 4X4 wooden skids. Used 2" steel pipe as rollers and a 5' steel bar to move it along. Took me a couple of days and some patience, but eventually got it in place without damaging anything......especially me!
Long ago, I watched an old guy move a 4 ton lead keel casting. He had cast it in a hole in the ground. With wedges, rollers, and a long bar, he moved it out of the hole, then positioned it under the wooden sail boat he was building. He then wedged it up and bolted it in place. Took him a couple of days, but there was never a mishap and he never broke a sweat. A great lesson to me.
Cheers
