ABSTRACT:
A powered lift platform apparatus is disclosed having a fixed support structure and two independently operable platforms which move in both the vertical and horizontal direction, for use with transport containers, such as trailers, shipping containers or rail cars. Each platform comprises an extended work surface or walkway and two moveable end platforms which extend perpendicularly to the extended work surface. Each platform may be independently raised and lowered, and each may be moved laterally toward the opposite platform. The distance between the two platforms and the length of the end platforms, coupled with the range of lateral movement of each platform, are such that the free ends of opposing end platforms can be juxtapositioned to create a rectangular pathway for workers to completely circle the transport container.
