ABSTRACT:
This invention relates to a ramp design permitting the positioning of a cargo ramp floor at any angle or height, which is integral with the aircraft such that it can be aligned to a vehicle transferring the load. The adjustable cargo platform assembly and the automated platform leveling system permits the ramp and ramp platform to be raised or lowered, but also permits the ramp platform to be tilted about a roll axis and aligned laterally with the floor of the load carrying vehicle to allow the cargo to be transferred to the aircraft. Efficient on-loading and off-loading of a palletized loading system (PLS) flatrack, directly off a PLS truck is achieved by such alignment. Actuators in the forward end of the ramp lift the platform as it rotates about the aft hinge point until the platform is even with the bottom of flatrack. After the platform has been lifted so that it is substantially parallel with the longitudinal axis of truck bed, roll actuators are used to raise and rotate the upper section of the platform about the longitudinal access of the ramp to match the plane of the truck bed. The roll alignment feature uses two selectable hinge locations located at the outer ends of the platform structure. Two sets of over center hooks initially lock down both sides of the upper platform structure to the platform frame. This permits the opposite side to be released and lifted using the opposite lock down side as a hinge. The cargo ramp floor may be outfitted with the various cargo rails and roller systems currently in use and the platform is not limited to any specific cargo handling system.
