  • Patent number: 6808057
    Abstract: The truck-mounted escalator is an improvement to mobile passenger stairways used to allow airline passengers to board and alight from large commercial aircraft. The improvement consists of motorizing the steps so they would function identically to escalator staircases commonly used in building structures. The truck-mounted escalator would consist of an electrical motor-driven escalator unit mounted on the bed of a dump truck style vehicle. The vehicle would feature a central support for the escalator unit and a hydraulic unit by which the escalator could be inclined for desired positioning. The escalator unit and hydraulic lift could be controlled by either of two control units, one located in the cab and the other on the rear of the truck bed. Electrical power for the motor, escalator unit, hydraulic lift, and control units would be supplied by the truck battery.

  • Patent number: 6755296
    Abstract: A self-propelled aircraft cargo belt loader is both propelled and operated hydrostatically. An engine, an electric motor, or a hybrid combination of both provides a power source to operate first and second hydraulic pumps. The first, or primary pump, provides variable fluid pressure used to propel the vehicle., while the second, or secondary pump, provides constant fluid pressure used to drive the conveyor belt, operate the hydraulic cylinders used to raise and lower the conveyor belt, and operate the vehicle's steering. The use of a hydrostatic drive system facilitates off-center placement of both the powerplant and the conveyor belt system, with the powerplant and conveyor belt system being positioned on opposite sides of the vehicle. As the powerplant is not covered by the conveyor belt system, engine access for maintenance and replacement is greatly enhanced.

    Abstract: A self propelled vehicle for transport and placement of an onboard supply of fill material in an onboard hopper. The hopper is connected to said vehicle at a point operatively positioned to discharge fill material placed therein on a conveyor belt mounted to a support structure. The fill material is deposited on the conveyor at a receiving and discharged at the distal end of the conveyor either directly or via a flow director attached to the distal end attached thereto. The flow director bifurcates the stream of fill material allowing the operator to place more or less of the fill in two streams using a plurality of independently adjustable channeling ramps. The hopper is optionally adjustable from an angle normal to the vehicle to allow for adjustment in the vehicle center of gravity on grades.
