Abstract: An aircraft load management system determines a cargo through a wireless communication system to rapidly position the cargo. RFID emitter tags on each piece of cargo are triangulated relative to an aircraft internal cargo bay. Real time cargo position information is displayed to facilitate direction of drivers, loadmasters and aircrew.

Even prior to onloading, cargo data is wirelessly communicated to the load management system to automatically plan the cargo load sequence. The load management system also autonomously loads remote controlled ground vehicles and equipment through communication therewith.

At second ends the arms are mounted in the frame so that they can move in a plane of rotation in such a way that when they are struck by an item of cargo travelling in a first horizontal direction parallel to the plane of rotation, the first ends of the arms are deflected downward from an upper operating position toward the frame.

Abstract: An adaptor is provided for a vehicle load bed having stake pockets along lateral edges. The adaptor allows pallets having indented peripheries to roll over the bed and to be locked in place on the bed. The adaptor has a base lying on the bed and guides in the form of upright walls disposed along lateral edges of the base. The guides keep the pallet on the bed as the pallet rides along the bed. Stakes on the bottom of the base are locked into the pockets to retain the adaptor to the bed. Extending from the walls are lips disposed over the pallet so as to limit or eliminate the pallet's vertical travel. The pallets ride on elongate rollers journalled between roller supports. The supports are fixed on the base parallel to the walls. Apertures of the same shape are defined both in the lips and the base and are aligned with one another. To fix the pallets to the adaptor, locking members are passed through the lip apertures, fit with indents of the pallets and passed through the base apertures.

Abstract: To secure containers on the floor of the cargo area of an aircraft, latches are known that comprise a frame and at least one latch hook, which is mounted on the frame so that it can pivot about an axle from a retracted resting position into an upright operating position. If due to inattentiveness of the service personnel the latch hook is left in its operating position and a container strikes against it while it is in this position, the result is often destruction of the floor structure. It is proposed to provide a safety device that allows the latch to be deflected out of the way when it is subjected to a predetermined overload in a direction parallel to the floor of the cargo area.

Abstract: A roller restraint assembly is removably mounted on the floor of a vehicle in an outboard location where it restrains cargo movement laterally but permits longitudinal cargo movement along its roller. This assembly has a pivotally mounted restraint arm which engages the base portion of a cargo pallet and restrains the pallet against vertical movement. When the cargo is moved longitudinally it drives the restraint arm aside on its pivot, thereby permitting longitudinal movement of such cargo. A roller is rotatably mounted on the assembly to facilitate longitudinal movement of the cargo while restraining lateral movement thereof. The roller further has a dampener incorporated therein which dampens and attenuates the impact of loads thereagainst.

The guide generally includes a hinge assembly, fore and aft pivots, a frame, and erection springs. In an erect position, the hinge assembly forms a shallow inverted V in side view with hinge axis at the apex such that a moving full size pallet contacting hinge assembly top forces the hinge assembly into a retracted position below the roller plane.
