ABSTRACT:
A self-propelled passenger lift vehicle for transporting a mobility impaired passenger between a first location and first elevation and a second location and second elevation against an aircraft fuselage adjacent an aircraft door is disclosed. The vehicle comprises in combination a wheeled frame, a generally horizontal platform movably mounted on said frame having a leading edge portion and a support portion for supporting the passenger, a drive motor connected to at least one of the wheels for moving said vehicle from said first location to said second location, a brake mechanism connected to the at least one wheel for controllably stopping and preventing wheel rotation, and a position sensor in the leading edge portion of the platform for sensing the presence of the aircraft fuselage. The position sensor automatically actuates the brake to lock the drive wheel upon sensing contact with the aircraft fuselage. This feature minimizes damage to the aircraft due to operator error.
