Abstract
A vehicle lift assembly prevents accidental slippage of a vehicle therefrom. The vehicle lift assembly comprises a plurality of vertically disposed posts and a runway slidably coupled to the plurality of vertical posts. A hoist system supplies the force necessary for elevating the runway along the plurality of posts. A sensor arrangement detects whether the runway has tilted beyond a predetermined angular displacement. A lift control circuit controls the hoist system to elevate the runway selectively in a prescribed direction, and suspends operation of the hoist system, when necessary, to prevent the vehicle from accidentally sliding off the runway.
