Automated storage and retrieval systems, sometimes known as ASRS or AS/RS, are made of a variation of computer-controlled systems that automatically place and retrieve loads from set storage locations in a facility with precision, accuracy and speed .As an important part of the modern logistics system, the automatic storage and retrieval system can realize the rationalization of the warehouses and the simplification of the operation.

An Automated Storage and Retrieval System is a combination of equipment and controls that handle, store and retrieve materials as needed with precision, accuracy and speed under a defined degree of automation. Systems vary from relatively simple, manually controlled order-picking machines operating in small storage structures to extremely large, computer-controlled storage/retrieval systems totally integrated into a manufacturing and distribution process.

Generically AS/RS refers to a variety of computer-controlled methods for automatically depositing and retrieving loads to and from defined storage locations. Within an AS/RS environment one would find one or more of the following technologies: Horizontal Carousels, Vertical Carousels, Vertical Lift Modules, and/or Fixed Aisle (F/A) Storage and Retrieval Systems, the latter utilizing special storage and retrieval machines to do the work needed to insert, extract and deliver loads to designated input/output locations within the aisles being served.

The right application of AS/RS provides a long list of user benefits! It has been demonstrated time and time again that Automated Storage and Retrieval Systems are proven technologies capable of effectively and reliably handling and buffering raw materials, work-in-process inventories and finished goods of all kinds, making it possible to totally integrate material handling storage, into the total process being served.

The single Mast stacker is one of the main components of the automated warehouse, dedicated to the elevated warehouse. The frame structure consists of struts, upper beams and lower beams, composed of rectangular frame, structural stiffness than the double column stacker is poor, suitable for the bottom of the warehouse below 16 meters below the lifting height of 2 tons to enhance the following. The stacker runs on the road between the shelves and is mainly used to carry the unit cargo loaded on the pallet or in the container. You can also open the corresponding goods

The double mast stacker is one of the main components of the automated warehouse, which is different from the single column stacker. The frame structure is a rectangular frame composed of two masts, the upper beam and the lower beam, and the structural rigidity is better, the quality is larger than the single column. Applicable to a variety of lifting height of the warehouse, the general weight of up to 5 tons, if necessary, can be larger, can be used for high-speed operation. The double column stacker runs in the roadway between the shelves and is mainly used to carry the unit cargo loaded on the pallet or in the container
