I have two 4 post lifts and a set of casters so I can move them around from time to time. Very handy, but a word of caution. When a 4 post lift is not bolted down, it can easily distort as the lift descends. Only a slight amount of uneven weight distribution or resistance can make one end or one corner hang up. This is because the lifts are cable operated and when one leg hangs a little, the others will continue to descend. If this is not attended, the lift can distort, not being bolted down. This can ultimately result in the entire lift racking to one side and flipping over.
I have observed the binding and seen the lift distort enough to elevate one corner off the floor. This is easily overcome by raising the lift, but don't be tempted to allow the lift to descend unattended. I still have both of my lifts, use them all the time and move them around from time to time as the ned dictates (moving one outside to facilitate undercarriage pressure washing of my off-roader was great!)
