ABSTRACT:
Wheelchair lift (10) includes a platform (12) mounted on a carriage (14) for vertical travel between the ground and an elevated location along a mast structure (16) through the use of a linear, lift actuator (18). Platform (12) includes an upper main section (20) and a lower movable section (22) that is horizontally extendible and retractable by a linear, platform actuator (24). The actuators (18) and (24) are cooperatively interconnected with and controlled by a power system (28) so that platform (12) is raised to a desired height before the movable section (22) is extended, and conversely the movable section (22) is fully retracted before the platform (12) is allowed to lower to the ground.
