    Abstract: A four point vehicular suspension system for a vehicle having left and right side frame members and spaced apart front and rear axles, comprising a plurality of lever beams having proximal and distal ends, a pair of which are each pivotally attached at their proximal ends, in spaced apart relationship, to each of the left and right frame members and attached at their distal ends to the front and rear axles, an expandable force-producing pneumatic bag disposed between each of the lever beams and the respective frame member to which the lever beam is pivotally attached, each bag being positioned between the proximal end and the distal end of each of the respective lever beams, and a source of air pressure and a valving system that is responsive to an unlevel position of the vehicle frame to selectively expand or contract the pneumatic bags to level the vehicle frame.

    Abstract: A work platform-supporting device is held by legs extendable by hydraulic rams and retractable by its own weight. A sensing device including a pendulum (43) attached by a stem (45) to a universal joint (46) controls the movement of the rams. Two pairs of control valves located at 90 DEG to each other are attached to the stem (45). One pair of control valves reacts to the pitch of the platform while the other pair reacts to the roll of the platform. These valves are attached to a hinge mechanism, which is connected to the stem by a ball joint (67). When the sensing device and the platform are level the valves are in a neutral position. When the platform becomes inclined the pendulum moves to a vertical position thus activating the valves. The valves allow hydraulic fluid to flow into the ram on the downhill side of the platform and the ram on the uphill side retracts allowing hydraulic fluid to return to the hydraulic fluid reservoir. The valves have built-in dampers and the pendulum is immersed in a viscous fluid (42).
