A method and device for moving an occupied wheelchair between two levels involves tracks mounted on stairs and a pull cable that is substantially aligned with the center of gravity of the chair and is anchored above the upper level. The tracks have a transition section between the lower level and a main slope of the tracks. The device can be used by a wheelchair occupant to ascend or descend the stairs without assistance from any other person. The cable has a winch which can be manually operated by the wheelchair occupant or power operated and controlled by a remote control in the hands of the wheelchair occupant. Previously, wheelchair occupants are moved between two different levels by ramps or elevators.
