Abstract: A pallet hold-down system having a horizontal and vertical movement securement apparatuses and a method of using the system where a rotatable member is interconnected with a vertical and a horizontal movement securement apparatus such that rotation of the rotatable member simultaneously locks both the vertical and horizontal movement securement apparatuses to prevent horizontal and vertical pellet movements.

Abstract: Methods for vertically restraining palletized cargo within an aircraft that quickly restrains and unrestrains vertical movement of transportation pallets of uneven shapes within a transportation bay employs a plurality of cams having upwardly oriented circular geared portion and downwardly oriented extended portion mounted onto the sides of the bay. Once a pallet is inserted into the bay with the outboard edges under cams urging the downwardly oriented extended portions to turn to accommodate distortions of the outboard edges, rotating the cams. Once the pallet is fully inserted into the bay, the methods employ locking levers with linear gears along the bottom mesh with the circular gears on portions of the cams preventing the cams from rotation. The extended portions of the cams with shock absorbing bumpers lie on the upper surface of the pallet restraining the vertical movement of the pallets. Alarm means to detect the status of the locking levers are also provided for.
