ABSTRACT:
An automatic leveling system for off-road vehicles having a cab and boom assembly rotatably mounted on a carrier base via a tilt table. The system includes a sensing device and control circuit for adjusting the level of the cab assembly relative to the base of the vehicle. The sensing device has a pendulum gimbaled within a housing. The pendulum has a pilot shaft extending upwardly therefrom and positioned proximate four switches for sensing changes in the orientation of the cab assembly. The switches are electrically connected to control circuits for a system capable of adjusting the orientation of the tilt table. A delay circuit is provided to inhibit re-leveling during extension of the boom.
