I also like the 1 Ton Telescoping Gantry Crane mentioned before, but unless you build it yourself out of scrap, it's expensive.
$600 + the trolley. Plus, I wouldn't use it enough and you have to store it somewhere.
The sprint car shop was hit by a tornado and the structural integrity is a concern. He's been fighting the insurance company for a year.
We leave everything we can inside the sprint trailer,..... outside of the shop.
