Murata Machinery USA, Inc. (Muratec) has developed the Ledger A3 mini-load, a high-density, four-tote carriage automated storage and retrieval system (AS/RS).
The system provides high-speed, simultaneous carriage loading and unloading of four totes for storing, picking and sorting small, lightweight goods. Providing high-density storage and retrieval for high-throughput distribution applications, the crane moves up to 400 totes per hour, travels at 984 feet per minute, lifts 360 feet per minute and has a size capacity of 13.4 in. wide, 18.9 in. deep and 11 in. high. Stacker cranes transfer Ledger A3 size (11 in. by 13.4 in.) totes individually or four simultaneously.
