Sliding Shelves

a system of cabinets or shelving with a manual or electric drive for moving the shelves along guide rails that are either suspended or run along the floor. Sliding shelves are used in warehouses, libraries, archives, and other storage areas. The shelves are placed close to one another and, as needed, can be moved singly or in groups into a free space the size of one row of shelves. The main advantage of sliding shelves is the highly efficient use of storage space.
