An assembly for machine leveling including a plurality of hydraulic cylinders having upper ends adapted for supporting the machine's base, a lower end, a shaft, and a port opening the cylinder; branch conduits having cylinder ends and pump ends, each branch conduit connecting to one of the ports; first shutoff valves connected to the branch conduits for alternatively permitting and resisting fluid flow within the branch conduits; a manifold conduit connected to the branch conduits; a hydraulic pump connected to the manifold conduit and adapted for raising hydraulic pressure within the manifold conduit to a shaft extending pressure; and an electrically modulated variable pressure relief valve connected to the manifold conduit and adapted for raising and lowering the hydraulic pressure.

Assembly for hydraulic fluid actuated machine leveling

A machine leveling pedestal incorporating a cylinder and piston defining an interior space, having a helically threaded outer surface, and having an upwardly facing land; a hydraulic fluid port opening the interior expansion space; a nut having a downwardly facing land and gear teeth, the nut being threadedly mounted over the helically threaded outer surface; a drive gear connected to the cylinder and piston for vertically slidably engaging the drive gear with the gear teeth, and, upon alternate rotations of the drive gear, rotating the nut about the cylinder and piston so that the nut vertically moves between a mechanical support position and a hydraulic support position, the upwardly and downwardly facing lands contacting each other upon movement to the mechanical support position, and the downwardly facing land displacing upwardly upon movement toward the hydraulic support position; and a motor connected to the drive gear.

Machine leveling pedestal

A hydraulic fluid actuated equipment leveling assembly incorporating a plenum having adjustment ports; an input channel opening the plenum; a disk valve operable for opening and closing the adjustment ports; telescoping and hydraulic ram actuated equipment support pedestals; hydraulic lines spanning between the plenum's adjustment ports, and the pedestal's hydraulic rams; and fluid displacing plungers connected operatively to the hydraulic lines for adjusting the hydraulic line's interior volumes.
