Abstract: An aircraft ground transporter is adapted particularly for the transport of wheelless, skid supported aircraft (e.g., helicopters) on the ground. The transporter is self propelled and includes seating for an operator thereon. The device is hydraulically powered and operated, with an engine providing power for a hydraulic pump, which in turn provides all lifting, steering, and mobility functions. The configuration of the vehicle includes a generally H-shaped frame, with the forward ends of the two arms of the H each including a steerable wheel or wheels thereon. Each arm includes a lifting bar thereon, which may be raised to lift an aircraft by the cross tubes of the landing skids. The opposite, rearward end of the vehicle includes the engine and most of the hydraulic apparatus, and seating and controls for the operator. Thus, the operator is always facing toward an aircraft being handled by the transporter, and may easily observe the transporter and aircraft being transported thereby.

Abstract: A maneuverable, wheeled, steerable vehicle is used for transporting helicopters of the type having landing skids. Such helicopters typically have cross bars under the body proper, with downward-curving arms to the skids. The invention includes two mutually parallel booms which extend from the vehicle body parallel and close to the ground. One of the booms is laterally movable toward and away from the other boom, which is fixed to the vehicle frame. In use, the booms are laterally spaced; the vehicle then goes forward to slide the booms under the cross bars of the helicopter body. Lift bars attached to each boom then raise the helicopter up so that the vehicle can transport it. The booms include a gang of small, hydraulically swiveled steering wheels at the ends distal the vehicle. Each lift bar swings upward on double parallel pivot arms at either end of each boom. The pivot axes are horizontal. The arms are of equal length to keep the lift bars horizontal.
