ABSTRACT:
An improved vehicular mounted jacking system controllably raises or lowers a portion of a vehicle relative to the terrain on which the vehicle is supported. Multi-chambered telescoping hydraulic jacks are mounted on the frame of the vehicle close to each of the several replaceable wheels. Each hydraulic jack is vertically oriented relative to the supporting terrain to lift a portion of the vehicle relative to the supporting terrain allowing removal of the desired wheel. Hydraulic power from the vehicle is coupled in communication with each of the multi-chambered telescoping hydraulic jacks to provide hydraulic fluid under pressure for actuating and extending the hydraulic jacks. A valved manifold is also disposed in fluid communication between the jacks and the hydraulic power source. The valves of the manifold are controlled to selectively extend or retract one or more of the hydraulic jacks.
