ABSTRACT:
A storage and retrieval system includes a continuous track and a plurality of individual storage units stacked in multiple columns or rows. Each storage unit is engaged with the track for selective movement along the track. Each storage unit includes two sets of wheels, a first set of wheels for engaging the continuous track, and a second set of wheels for engaging support rails disposed above an upper rail of first and second tracks of the continuous track, so as to support the storage unit as the storage unit passes gaps in the upper rail due to intermediate vertical rails extending downwardly intermediate ends thereof.
