ABSTRACT:
A cargo handling system for use in combination with an airplane cargo compartment having a floor structure and a door opening moves cargo placed in the loading area inside the compartment at the door opening to the further recesses of the compartment and returns the cargo to the loading area for unloading. The system generally comprises fore and aft end panels, each attached to its own looped cable and movable from a position adjacent its respective end of the compartment to a position adjacent its respective side of the door opening; a movable main panel attached to a power cable; a drive means, such as a hydraulic cylinder, is attached to the power cable and drives the main panel in the door area between the door positions of the end panels; and indexing plungers which selectively couple the main panel with a cable of an end panel such that, when coupled, the end panel is driven simultaneously with and in the same direction as the main panel. The cables and rolling supports for the panels move in passageways in drive strips which extend the length of the compartment. Roller strips, lining the compartment floor, reduce friction. Exemplary embodiments include a removable door adapter and ball mat which aid in loading bulk or containerized cargo. In the preferred embodiment, the hydraulic cylinder is in a power pack which is removably attached to the main panel.
