Abstract
A wheelchair lift designed for mounting in the stairwell of a railway car. The lift includes a vertical translation member which is attachable to one wall of the stairwell, and a platform assembly attached to the translation mechanism so as to be movable between an upper position, where the platform assembly is substantially coplanar with the floor of the railway car, and a lower position, adjacent the railroad bed. The platform assembly includes a main platform attached to the translation mechanism, and a pivot platform, pivotally mounted to the outboard end of the main platform. In the stowed position, the pivot platform is positioned underneath the main platform. Retractable barriers are provided at the outboard end of the pivot platform and the inboard end of the main platform for preventing a wheelchair from rolling off the platforms.
