摘要：
An apparatus that permits a wheelchair to traverse stairs. A carriage platform supporting the wheelchair is housed in an inclined ways assembly and moves by means of a rotated threaded rod supported in the ways and traveling nuts fixed to the carriage; a debarkation ramp hinged to the carriage, spans the distance and elevation difference between the carriage and the desired landing point.
