ABSTRACT:
A series of hydraulic jack units are mounted on the frame of a vehicle. Each jack unit is controlled from a central controller inside the vehicle and includes electrical means for activating the jack, automatic means for locking the jack in the extended position, and selectively activatable means for releasing the jack and returning it to its retracted position. As a result of this arrangement, any portion of the vehicle may be raised to facilitate maintenance, or to provide security against theft.
