You can do a fair amount of work with a pinch + point bar ~6ft long and a setup of plywood scraps, go with 3/8" thick and 3/4" thick and then typical 2x framing timber.
Its just a slow dance of moving around in circular fashion and setting 3/8" shims up as you go. You'll need some fulcrums too as it gets higher as well.
Then, depending on the machine you can roll in a pallet jack or set 3 skates. I've moved some stuff out of plants where the requirement was "bring your own rigging, none supplied by owner" and what I brought was above, worked very well.
If you have a lot of machines I'd consider renting a forklift. Even if you can only get a 5k unit and can only lift half of the lathe at a time it will make the job easier. Ideally you could get a larger one to handle it as one unit but sometimes the transport on those are tough to get organized.
