| | Because vertical systems can be configured with many shelf and tray variations, load data is used to design the application to the need. For the storage of stamping dies, weight is a primary consideration. To define system requirements, you must calculate average weight density to determine shelf or tray loading capacity. Once load data has been determined and grouped by size and weight, it can be used to determine optimum vertical spacing, depth, and width. Consideration also must be given to the physical layout of the installation site. The clear height of the building interior will determine the height of the units and the total number of shelves or trays allowed in each unit. It is possible to estimate space savings in square feet and percentages using general formulas developed by automated storage and retrieval system manufacturers, Converting a standard shelving system to a vertical storage and retrieval system can save up to 100 shelves, or 91 percent of space. Converting a standard drawer system to a vertical storage and retrieval system can eliminate up to 65 cabinets, or 86 percent of space. For example, in a facility with a ceiling height of 40 feet, a vertical storage and retrieval system can eliminate up to 100 shelving sections with a resulting space savings of up to 929 square feet, or 91 percent. For a ceiling height of 30 ft., a vertical system can eliminate 46 drawer-type cabinets for a space savings of 311 sq. ft., or 80 percent. | |
