  • Patent number: 5525019
    Abstract: A hydraulic rear platform lift for an aircraft loader provides for an increased height by providing a pair of lifting levers actuated by a hydraulic cylinder-piston which extends into cutout space of a forward support frame and mates with the scissor type lifting beams of a forward lifting platform. The lifting mechanism generally consists of a chicken leg lever and tension bar with the actuating force provided by a cylinder--piston connected between the chicken leg lever and the other end of the tension bar. For even greater lifting heights, one end of the tension bar may be placed on the leg of the rear scissor beams with appropriate cutouts being provided in the rear support frame and rear elevatable platform.
