Only issue I had was that no matter how much I tightened the bolts for the base, it would go out of square. I ended up shimming between the uprights and base and that easily took care of that. Otherwise, I easily popped my wheel bearings in and out.If needed, you could probably swap for a heavier duty jack, but I don't believe the frame will withstand much more than 6 tons.Also, I didn't look at the dimensions and was expecting something a bit bigger. I guess I was expecting a freestanding model, lol... it's more of a bench top press. Still works fine for my uses. If not better since it's more portable.
