This is old school HD engine hoist that can be towed to where ever it's needed. Old unit made much, much stronger than most current day hoists. If you are old enough to know Walker jacks, I replace it a few years ago, but because of lack of use, the seals have started leaking. Not a hard fix, but I too many other things to do. Take advantage of my weak moment if you're interested in it, otherwise I will get to it in the future but price will be higher. I have had a fully loaded big block Chevy with transmission attached and it handles it with no problem.
Be advised, this is a tough HD cherry picker, it is NOT pretty.
