[Ken Greene]

for any ceiling mounted crane your ceiling joists need to be spec'd for the weight by an engineer, and if not up to specifications beefed up accordingly. then a rail system needs to be mounted to it to provide forward and back movement. then a chain hoist of some type needs to be mounted to the rail system. After paying for all of this you could of bought a lift for the whole car.
If you still want to go through with all the above, Grainger or Mc Master Carr both carry electric chain hoists for over head mounting.
