A good lathe!
Hopefully it will come on a lift gate truck so you won't need to figure out how to get it off the truck.... If you do need to do that, try renting a couple sections of pipe scaffolding, which will give you a 12' height. Put a heavy beam across the top with a come-along attached to be your "crane." Back the truck up to it, hook on the come-along, slide the lathe out, and lower away. But that could get pretty dicey if you're not a competent rigger. Arrange for a lift gate on the truck!
Your best bet may be to take it apart. You ought to be able to take the lathe off the cabinet, take out the motor, take off the tailstock, etc. You'll still have some fairly heavy pieces, but they will be in the 400-pound range instead of 1200 pounds.
Or, if you want to move it intact, try some 2" iron pipe as rollers. You ought to be able to buy three pieces, maybe 3' long, pretty reasonably. You may also need a couple of planks. A couple of 2x6x8s ought to do it. It's amazing what you can do with a few rollers and levers. Look at the pyramids, after all. Just watch out for it being top-heavy and falling over on you.
