ABSTRACT:
This invention relates to a lift device adapted to transfer wheelchair passengers to commuter aircraft. A base and optional four post system provide support for a vertically moveable platform. An apron, which can be used either as a ramp from lowered platform to ground or a bridge from elevated platform to aircraft is provided. The platform is preferably raised and lowered using ball or acme screw-bushing brackets. The platform can be used to load and unload passengers from rear and front door commuter aircraft, on either side of the fuselage. The lift can be incorporated into a wheeled chassis, which can be lowered into ground contact at the position of use. Optionally extendible stairs are present to allow other passengers to enter or leave the aircraft using said platform and apron.
