Yea, I use them. They are great! I believe mine are called
Car Skates, and have a decent weight rating since my old
Birds weigh over 4000 lbs each. Seems like they were about
$180. They come in handy for many other uses too....i.e.
when I'm dropping an engine in a car, I have the car up on the skates, and the engine on the hoist....once I've got the engine
down in the engine bay area, and have to adjust a tad to get lined up with the cross member/motor mounts, it's very very nice and convenient to be able to move the car to the engine, and not have to move the engine hoist.
Lots of companies make them....as with any tool, there are cheap ones and more expensive ones....you get what you pay for.
