A storage system includes a rack with a plurality of layers, each layer including an aisle (303) and a plurality of rows extending from the aisle (303) defining storage locations for items (308). A shuttle usable with the rack includes a first cart (102) movable along the aisle (303) and a second cart (104) configured to be carriable by the first cart (102) and to be movable along a row. The second cart is configured to carry an item (308) between the first cart (102) and the storage locations. A conveyor is located on one of the first (102) or second carts (104) to move the item onto or off the first cart (102). Related methods of storing and/or retrieving items (308) from a rack are also disclosed. A rack system is disclosed and is readily assembled without welding, transferring loading so that the weight of the rack and any item stored therein is supported by the upright elements via support brackets. |
