Abstract:
A system for leveling and stabilizing a vehicle upon a ground surface, the vehicle having a frame and an axle pivotally connected with the frame, the system comprising:a frame leveler device configured to move the frame with respect to the axle;a stabilizer device mounted to the frame and including a pair of arms, each arm having a portion contactable with the ground surface, and two hydraulic stabilizer cylinders, each stabilizer cylinder having a piston with a rod connected with a separate one of the arms and a base chamber on the other side of the piston; anda fluid exchange line extending between the base chamber of one stabilizer cylinder and the base chamber of the other stabilizer cylinder;wherein movement of the frame with respect to the axle when the arm portions are in contact with the ground surface causes hydraulic fluid to flow from one stabilizer cylinder and into the other stabilizer cylinder such that the piston rod of the one cylinder retracts and the piston rod of the other cylinder extends while the stabilizer arms remain substantially stationary.
