Abstract
In-place vehicle jack assemblies of the pivoted lever type to be permanently mounted at the front and rear of the vehicle frame structure, each of the jack assemblies comprising a unitary device which is independently operable by an electric motor, and independently selectively controlled at the jack or remotely from the control compartment of the vehicle, control circuits for the jack assemblies being interlocked with the ignition system of the engine, so that the jacks are operable only when the ignition switch is in an "off" position.
