When the lift is being used as a drive-on lift, these legs are folded away, and when the lift is to be used as a free-wheel type, these legs are opened out and hang vertically, in which position the vehicle may be lifted off the vehicle support ramps by lowering them, thus pushing the underbody support upwards via the legs away from the support ramps and lifting the vehicle thereby.
