  • Modular cargo loading and unloading system
    Patent number: 4780043
    Abstract: A modular cargo loading and unloading system for installation in the lower lobe compartment of an aircraft is disclosed. The system includes a doorway transfer unit (17) and a plurality of longitudinal units (19). Each of the units includes conveyor belts for supporting and moving cargo containers. The doorway transfer unit (19) includes perpendicular conveyor belts (35, 37) that are selectively raised, lowered and powered to change the direction of cargo container movement at the entryway of the lower lobe compartment. The longitudinal units (19) include powered belts (51) that move the cargo containers to and from their destinations in the lower lobe compartment. A quick-change mechanism that attaches the modular units to the cargo tie-down receptacles located in the deck of the lower lobe compartment allows the units to be quickly installed and removed.
