I'm all for safety, but a 2 post lift is a lot different from a jib crane. The 2 post is lifting near the center of the car and near the center of gravity off the car. There isn't much force trying to tip it over, the force is mostly straight Down. A jib crane is lifting a heavy load off to one side of the base, so the forces on the floor are much higher. Just saying.
