  • Patent number: 5018926
    Abstract: Storage and retrieval apparatus and method using pallets for storing vehicles and other loads. A number of storage levels aligned vertically are reached by a pair of lifts in shafts which bracket the levels. A transfer mechanism can push a pallet and automobile from either lift onto any level. Each level is always filled with pallets and sized to exactly hold an integral number of pallets. When a pallet is pushed into a level from one lift the intermediate pallets are pushed laterally to the opposite lift, resulting in the farthest pallet being ejected onto the opposite lift located at the same level. Separate loading stations are provided on ground level for each lift. An automobile can be driven on or off a pallet or a load placed on or off a pallet at the loading station. A loading station mechanism can move a pallet with a load to be stored from the loading station onto a lift.
