Abstract

An apparatus providing access by a handicapped person from a landing to a guideway mounted vehicle includes a support structure having a pedestal portion and a housing extending upward from the pedestal. A lift, mounted in a lift opening of the support structure, includes a platform, linkages interconnecting the platform to the housing, and movement apparatus coupled to selectively move the platform between a lowered position adjacent a landing, a raised position adjacent the top of the pedestal and a vertical storage position in the lift opening. A bridge member pivots between a horizontal position extending into the doorway of a light rail vehicle and a vertical storage position in the passage adjacent the bridge opening. Roll-up doors are mounted in the top region of the housing for being selectively rolled down to a position to cover the lift opening and bridge opening when the lift and bridge are in their respective storage positions. A lift disabling mechanism includes a safety plate spaced distance below the platform bottom in non-contacting relationship to platform supports and a plurality of independently responsive switches attached between the safety plate and the platform bottom. Upon movement of the safety plate relative to the platform, the lift motor is disabled by the switches so that movement of the platform immediately stops.
