Robert,
How about a "gantry" crane. I was looking at them for an application at my
work. They look kind of like a swing set but with wheels on the bottom of
each leg. They come in different length spans to clear the widest of
cars. You can roll them around and they can be taken apart easily for
storage. The company I was looking at was called Spanco, I believe they
have a web site too.
