The jack is lighter than a regular hydraulic 3-ton one, so it's really easy to move it. Pneumatics is magic. I didn't use it to lift the heavy stuff yet, but middle weight F250 is lifted in seconds, as opposed to minutes with the regular jack, and without any pumping - hallelujah! Update: I have used it for the heavy stuff. A school bus based on E450, around 11000 lbs, was lifted fast and with zero issues. I certainly love this air jack!
