Jonathan,
An engine lift will do nicely to move the lathe. I used a 2 ton lift to get my lathe into my workshop a few weeks ago. I had to cross a gravel area for around 6mts before getting to the stairs of my workshop. I used 40mm thick interlocking flooring boards at 600mm wide by 2400mm long to give a running surface. When I got to the stairs I then spanned then with 6 of 100mm x 100mm fence posts to support the weight. Then the lathe was lifted around 400mm high and placed on the posts running up the stairs. Then the lifter was moved inside the workshop and used to pull the lathe further up the ramp to get it in position for a straight lift to go to its final position. This worked very well and just required care and attention as with all lifting procedures. The thing to remember with engine lifters is that they cannot work outside their footprint.
Best of luck.

Regards

Ian
