<p>A platform conveyor system (21) for changing the direction of cargo containers (27) at the entryway (17) of the lower lobe compartment (11) of an aircraft fuselage (13) is disclosed. The platform conveyor system (21) includes a plurality of lateral conveyors (25a, 25b and 25c). During loading the lateral conveyors (25a, 25b, 25c) move cargo containers (27) through the entryway (17) to a position above a pair of longitudinal conveyors (33 and 35). After a cargo container (27) is positioned above the longitudinal conveyors (33 and 35), the lateral conveyors (25a, 25b and 25c) are deenergized and the longitudinal conveyors (33 and 35) are raised and energized. The longitudinal conveyors (33 and 35) move the cargo container (27) onto another conveyor mechanism that moves the cargo container (27) to its final destination in the lower lobe compartment (11) of the aircraft fuselage (13). After the cargo container (27) leaves the platform the longitudinal conveyors (33 and 35) are lowered. During unloading, a cargo container (27) is first moved to the previously raised longitudinal conveyors (33 and 35), which move the cargo container (27) to a position above the lateral conveyors (25a, 25b and 25c). Then the longitudinal conveyors (33 and 35) are lowered and the lateral conveyors (25a, 25b and 25c) are energized to move the cargo container (27) through the entryway (17). </p> |
