Hanging a car from the roof.

[Robert Leigh]

Has anyone hung a car from a chain block?

I need some more room in the shed to carry out the 10year test on my steamer. So plan to gain some room by hanging one of my cars from the roof of the shed on a chain block. 

Has anyne done anything similar and can give me some ideas? Where abouts is the centre of gravity do you think?

Current thinking is to make a built up (T section) timber spreader beam (to get straps outboard of the body) with a ring in the centre and a ring on each end. Then have 4 seperate straps. 2 each side from the beam to each wheel (car to be lifted has no wings). Ill use ratchet straps so I can adjust lengths to pick the car up square. It needs to go at least 15 foot in the air.

Any thoughts gentlemen? 

For the record I am a structural engineer so I am more than capable of calculating F.O.S for each component of my lifting tackle, I am also more than happy to pick it up on non certified and home made gear.

You can easily get a good idea of where the centre of gravity is by jacking up the car on a trolley jack using a large section wooden beam (2 bits of 4x2 bolted together?) across the chassis, trying different positions just off the floor until you can rock it with one finger. Just a suggestion.
