My friend helped me unload my lathe from a pickup truck with an engine hoist. It was very simple. Just lift the lathe a tiny bit and drive away. The problem is that the lathe might try to spin if anything shifts. I got my arm caught somehow between the lathe and the hoist when he asked me to give the straps a tug. I screamed, and he yelled back at me, "Cmon, it's only 400 pounds, not 4000 pounds. Just get in there and muscle it." Good moving practice is never to rely on muscle for anything over a few hundred pounds. You should look like you are pushing a feather. Do not body slam loaded engine cranes. Do not yank backwards on the crane to get it to roll over a crack in the driveway. If it doesn't roll, use a come-along or a winch. Even better, use one on both ends, since if you are only pulling with one, it can take a nasty hop once it clears the obstruction or once the wheel caster suddenly straightens up.
