We have HF floor jacks. Both the steel and aluminum versions. They both work fine. 

Also have an air bag (not HF) roll-around lift. It works fine also. But, it seems easier to place the typical floor jacks under frames or whatever you're lifting vs the air bags.

I think the really heavy-duty truck-lifting jacks rated @ 40T are just big air bags in a round can. We have the Gray HD jacks.
