A little redneck engineering.
If it can be lifted at all then once you have moved it near the bench, you can chock it on up. No, I don't know if chock is a real word or right word. Rednecks word's don't have to mean anything, words just fill in for our normal grunts and shrugs as we proceed to crush Billy-Bob and develop multiple hernias
Here is what I am thinking. Several 4x4's and some 2x4's with a bottle jack or two. If you can get it high enough to get a jack under it, then you can lift it 4 - 6 inches at a time. I'd use a dog-leg and 4x4 to make the first lift, and lift one side at a time. Remember, "give me a large enough fulcrum and I can move the world." It'll be slow, and you still have to move it onto the bench. Please Please be careful, cause I ain't responsible if it falls on you.
All said, I'd have to let the machine sit till I could afford an insured pro to move it into place.
Best of Luck and Many wishes for your safety if you decide to do this yourself.
