A storage and retrieval machine comprising a base adapted to move horizontally along a supporting surface, a generally vertical mast supported by the base, a carriage supported for generally vertical movement along the mast, and an extendable and retractable shuttle mechanism supported by the carriage, the shuttle mechanism including an upper plate fixed against horizontal movement relative to the carriage, an intermediate plate which is located below the upper plate and which is supported by the upper plate for horizontal movement relative thereto, a lower plate which is located below the intermediate plate and which is supported by the intermediate plate for horizontal movement relative thereto, and hoops on the lower plate for selectively engaging a load, the shuttle mechanism being operable between a retracted condition wherein the intermediate plate is located directly below the upper plate and the lower plate is located directly below the intermediate plate, and an extended condition wherein the intermediate plate extends outwardly in one direction relative to the upper plate and the lower plate extends outwardly in the one direction relative to the intermediate plate.

Automatic storage and retrieval system

An automatic storage and retrieval system comprising a main track having an end, a storage rack which is adapted to be fixed adjacent the track and which defines a plurality of storage locations, a storage and retrieval machine which moves along the track and which places objects in and removes objects from the storage locations, and a maintenance module fixed adjacent the end of the track so that the maintenance module serves as a maintenance area for the storage and retrieval machine, the module also providing a container for packaging the storage and retrieval machine for shipping.
