I just moved a 13x40 jet lathe into my shop. They loaded it on to my trailer at the dealer. A couple of suggestions. Rent a "toe jack" (I made one out of a small hyd jack). cribbing a come a long & 2x8 planking.
Lift one end then the other and work the planks underneath, and set it on some pipe rollers (like the old days), you can steer it just about any where in your shop. I have done this with 2 lathes and a vertical mill by myself
if you have or can get a tilt bed trailer that would help a lot.
Be careful if you have never done this before as this equipment is surprisingly top heavy
