ABSTRACT:
A vehicle leveling system utilizing a plurality of support assemblies mounted on the bottom of the vehicle for rotative movement between an upper storage position and a lower operating position. Each support assembly includes two hydraulically extendable plungers which are operated in automatic sequence, the first plunger extending to rotate the support assembly into a vertical operating position and the second plunger then extending into engagement with the ground. Retraction of the plungers and return of the support assembly to its upper storage position are accomplished by spring means. The support assembly also includes structure which will respond automatically to excessive internal pressure to permit its rotation without damage either to the system or vehicle should the vehicle be moved inadvertently while the second plunger is in engagement with the ground.
