ABSTRACT:
A shuttle guide for a shuttle of a storage and retrieval machine having a mast and a carriage on which the shuttle is mounted. The shuttle includes first and second plates movable relative to each other in directions transverse to the mast for carrying and depositing in or retrieving a load from a storage space. The shuttle guide comprises a first guide member having a downward facing straight guide surface extending in the transverse directions of movement of the plates and a second guide member having an upward facing inclined guide surface. The inclined guide surface is inclined upwardly relative to one of the transverse directions. A first guide roller is positioned in engagement with the straight guide surface and a second guide roller is positioned such that it is engageable with the inclined guide surface and guides one of the moveable plates in an upwardly inclined direction toward a storage space. Downward deflection of the first and second plates caused by the weight of the shuttle and the load is thereby counteracted.
