OverviewShipping notices are downloaded from the Host to the WCD and Hanger Cell Directors. The orders are converted to movement commands on the WCD and sent to the equipment.

Workstation operators retrieve parts from the miniload ASRS and place them on conveyor which routes them to their destination. Unit Load pallet parts are retrieved from the ASRS and routed to pickup points via conveyor.

The system provides aircraft parts to 4 hangers. The overhead monorail system transports parts to the hangers 3 and 4. Parts arrive in totes via a lowerator and are returned to the warehouse via an elevator to the monorail.

The miniload ASRS has 5,928 pan locations. Each pan has multiple compartments with welded-in-place dividers and a 300 lbs. storage capacity. There is a miniload ASRS transfer device which allows the storage and retrieval machine to be routed from one aisle to another as a backup in the event of a major component failure.

The Unit Load ASRS contains 1,560 free standing locations each with a capacity of 1200 lbs. Then conveyor transports the heavy and large parts inventory on metal clad pallets. Lift trucks move the pallets, directed by commands via radio frequency terminals.
