yeah..some work as a rotissery...but the central axis does not go all the way through each side of the axis holder bars....kinda looks like swingers for kid, without the swingers...
and then you bolt the car on each side of the splited axis....this is mostly used in the hot rod industry, cauz they use the holes where the frame would originaly mount to hold the car up on the axis......
and i've seen some.. that looked pretty weird...it was like 2 circles made out of 2 inch pipes, with several hooking pad all along the inner side of each circles...then then would run the car in the middle of those circles...then they would use air ratchet to secure each pad firmly on the car...adn then roll the car wherever they needed too...i guess the whole wait of the car is distributed into each pads so it doesn't crush the car...
and most of the time...the cars are mostly stripped out when they go in these jigs...
