[US]Automated warehousing system and methiod background of the invention filed of the Invention The present invention relates to automated storage and retrieval systems (AS/RS), and more particularly to material handling systems for storing and accessing palletized material in large multistory automated warehouse buildings. Description of Related Art Automated warehouses and automated storage and retrieval systems (AS/RS) can reduce costs, pilferage, and damage because far fewer workers are needed for otherwise similar operations. Retrotech Incorporated (Fishers, NY) markets various automated warehouse systems and material handling robots. One such system, ACTIVEZ is a mechanized material handling automation technology for continuous product flow. Loads are not assigned a location within a system, rather they are assigned a dynamic path into and subsequently through the system using a transport design that overes the limitations of conventional deep lane storage. The technology was originally marketed in Europe under the tradename ACTI7M by Naaraharju Oy in Finland. Typical applications for ACTIVM include existing warehouses which had their manufacturing sources nearby, and the packaging and palletizing lanes, loading docks, and other services were already in place. But, the Retrotech system and other conventional approaches bog down and bee very inefficient as the design capacity is reached. Users cannot immediately access every and any pallet of product without having to dig throughothers to get to it. Systems like the Retrotech system have cartsslaved togetherin groups that are constantly moving. Only one in the group is doing any useful work at any one time. United States Patent 4,732,524, issued March 22,1988 to Seppo Suominen, describes some of the details found in the Retrotech systems. One of the disadvantages of this system include that the carts39。winch cables stretch and their drums wear out, and this affects the carts39。ability to stop at the proper location. Another disadvantage is that this system requires a high degree of maintenance. It is also advantageous for any AS/RS system to be able to handle a wide variety of pallets. Some conventional systems are very particular about the pallets that can be used. If ordinary and inexpensive pallets could be utilized, the potential savings in pallet costs can amount to over $200,000 per year in a 10,000 pallet system. In the Retrotech system, a pallet can be moved ten to thirty times before it is finally shipped out. Such excessive handling can cause unnecessary damage to the product, and may shift the load on the pallet making it unstable. Summart of the invention an object of the present invention is to provide an automated storage and retrieval system that is economical to install and operate. Another object of the present invention is to provide an automated storage and retrieval system that is efficient and has high throughput. Another object of the present invention is to provide a system that uses minimal labor. A further object of the present invention is to provide an automated storage and retrieval system that handles the pallets and their loads as little as possible between input and output. A still further object of the present invention is to provide a system that can operate at 100% capacity with no loss in efficiency. Briefly, an automated warehouse system embodiment of the present invention is contained within a warehouse building with at least one freight elevator. One such freight elevator and shaft automatically accepts ining material on pallets. A rotating forkliftlike attachment mounted inside the loading elevator can extend its forks to reach out and bring in material loaded on a standar
