Patent ID: 7270061

Claim:
A rail-car unloading apparatus configured to move over a surface, comprising: a frame structure positionable over fixed rails of a rail road track and having opposite first and second outer beams oriented substantially parallel to the fixed rails when the frame structure is positioned over the fixed rails; hydraulic arms, coupled to the frame structure, with at least two of the hydraulic arms extendable from the first outer beam of the frame structure and at least two of the hydraulic arms extendable from the second outer beam of the frame structure, the hydraulic arms being extendable in a substantially lateral orientation with respect to the first and second outer beams; and hydraulic legs coupled to the hydraulic arms and extendable between the hydraulic arms and the surface, the hydraulic legs operable to move the frame structure between a non-elevated position and an elevated position with respect to the rail road track; wherein the hydraulic arms are configured to move the entire frame structure laterally toward the hydraulic legs disposed on one of the first outer beam and second outer beam of the frame structure while the frame structure is in the elevated position.
