Abstract: A passenger lift for loading a passenger to and from an elevated access opening features a wheeled frame, a first parallelogram linkage coupled to the frame proximate a first end thereof and a second parallelogram linkage pivotally coupled to an output link of the first linkage. A passenger platform is pivotally carried on the output link of the second linkage. Through pivoting of the linkages by respective actuators, the passenger platform is movable between a lowered position adjacent a second end of the frame, and raised positions in which the platform is situated nearer the first end of the frame. The frame is open at the first end to define a gap between side members of the frame to accommodate a lower end of a staircase for accessing the elevated access opening. The platform thus forms an approach to the staircase when the platform is in the lowered position.
