AUTOMATED STORAGE & RETRIEVAL SYSTEMS

Automated storage and retrieval systems, usually referred to as AS/RS are computer controlled systems for storing and retrieving products in warehouses.  These systems require the use of virtually no manual labor.

Unit-Load AS/RS systems are bigger systems that typically store pallet loads.   Smaller systems which are commonly called mini-load AS/RS allow selection of items in totes, trays or cartons.

AS/RS are configured with rack laid out with narrow aisles between.  There is a raised metal rail down the center and a tall mast travels through the aisle along the rail.  When the mast reaches the storage location, a carriage travels up the mast to the picking spot.  An automatic mechanism then reaches into the storage location to retrieve or return the load.  This mast is usually called a crane.

The Unit-Load AS/RS systems are designed for larger loads which are pallets or pallet-sized loads.  Some systems are over 100 feet tall.  Whatever the application, UNARCO's time-tested engineering can design a system to meet building codes and withstand the tight tolerances required.

The benefits of a fixed aisle system such as AS/RS mainly lies in the minimized amount of space required and the reduced labor needed to store and retrieve materials.  With proper UNARCO engineering, warehouse productivity can be increased substantially.  Systems can also be adapted for use in freezers and other harsh environments that can create hazardous conditions for workers.  Because of the computer technology involved AS/RS can create a very accurate form of inventory control.
