The Ledger A3 mini-load automated storage and retrieval system (AS/RS) is an industry-first high-density storage system with high-speed, simultaneous loading and unloading of four front hook trays used for storing, picking, and sorting small, lightweight goods. 

By simultaneously loading and unloading each of the four front-hooked trays, the Ledger A3 delivers double the capacity compared to a conventional mini-load AS/RS with one or two deep storage, moving 400 trays per hour and improving storage capacity with 1.3 times more efficiency than the conventional AS/RS.

Muratec will showcase this industry-first Ledger A3 high-density AS/RS at ProMat 2023, in Chicago, from March 20-23, Booth S2703a. 

Designed to provide maximum storage and retrieval at high speed for high-throughput distribution applications, the Ledger A3 travels 984 feet/300 meters per minute, lifts 360 feet/110 meters per minute, and handles weights up to 15 lbs./7 kg per tray or 60 lbs./28 kg per four-quad carriage. 

This mini-load doubles the storage/retrieval capacity of a conventional mini-load AS/RS that typically offers 1 or 2 deep storage. The A3 (11.7 x 16.5) 4 quad trays move individually or simultaneously, sorting small items at large capacity and at scale with unfailing precision. 

Together with Muratec’s rail-guided, bi-directional case sortation loop or “SHUTTLINER,” the Ledger A3 can operate as a highly optimal goods-to-person (G2P) system enabling minimal material handling, further boosting throughput.  

Muratec’s North American debut of the Ledger A3 at ProMat 2023 follows multiple successful implementations in high throughput warehouse and distribution environments moving small goods in the medical & pharmaceutical (syringes, pill bottles), cosmetics (tubes, bottles, jars), and food & beverage (confectionery products, candy) sectors.
