FWIW, For anyone who is looking at getting a hoist here is some stuff I have discovered that may be of interest.
My 3M wide X 9 M long garage only has 2.4 M high walls and only about 3M under the center gable - not very high.
Like everyone else originally I really wanted a 2 poster, but even a 4 poster didn't seem possible for my garage.
However after some research and a lot of measuring I was surprised to discover that with a 4 poster that could be moved, I could locate it in a spot that when raised I could
full head clearance (6 ft) under the floor of my MR2.
The targa tops only have about 100 mm under the rafters, but I did fit a limit switch.
Now after using it for about 5 years, even if I had enough roof clearance and was doing it all over again, I would still go for the 4 poster.
Pros:
!. Only needs a low garage roof. (for an MR2 anyway)
2. Doesn't need special footings, only a stock 4 inch reo concrete floor and doesn't need to be bolted down.
3. Easily movable.
4. More stable than many 2 posters.
5. Only needs a 10 amp power socket.
6. Opening doors will not foul the posts.
7. Great tool /parts rest right where you are working.
8. I always park my car on the runway, so I don't need to mess around with positioning arms if I want to lift.
9. Although some people don't know, with the use of a good trolley jack it's easy to get wheels free with the car securely held if you only need to work on one end of the car at a time.
But I also use modified non-slip jack stands, and jack
top adaptors to safely locate under the X members F/R
Cons:
The only one I can think of is that you have to be careful not to bump your head on the runways when moving around, but that will also apply to a 2 poster although not as much.
