Abstract
A storage and retrieval system includes a plurality of storage bins arranged in spaced fashion. An extraction mechanism is provided to engage an edge of the bin defined by a sidewall and a bottom of the bin for moving the bin with respect to a storage location and a shuttle device. The extraction mechanism is movable along a first path in either direction with respect to a longitudinal axis of an aisle. The extractor mechanism is extendable below the bottom of a bin in a rest position, such as at a storage location. When the extractor mechanism has reached a position adjacent to the outermost end limit of travel, a tab actuating mechanism is engaged to move upwardly extending tabs between an extended position and a retracted position. A shuttle device is movable horizontally and vertically within a vertical plane for carrying the extractor mechanism and a selected bin from a first selected location, such as a storage position or a bin conveyor position, to a second selected location, such as a loading/unloading position.
