Scissor lift anyone?

My biggest fear with that lift is the footprint width. It's very narrow where it meets the ground. Seems like it might be easy to tip over. PErhaps if you mounted it to the ground somehow....but you could only mount one end since the end with the wheels needs to be free.

With the car in the air I pushed as hard as I could and barely got it to wiggle. Pretty sure that as long as it is reasonably centered, it ain't coming off. Think about it. In this litigious country, the lawyers would be having a field day if people were getting hurt from design or implementation issues with these lifts. Having said that, you can't fix stupid..
