This is one of my biggest fears in our shop. I have dropped a jet ski, lift arms kicked out, but never a car or truck. Some shops take the safeties off the arms on lifts that keep them from moving when in the air, so you can adjust them easier, thats what caused ours to kick out from under the ski (they were already off, we didnt do it). Id agree with whoever said that about picking it up by the body, not the frame. Or as new as the chassis looks it may have been a frame swap from a collision repair gone wrong, lifting the body to put back on the frame, but that doesnt explain how the chassis got upside down lol.
