ABSTRACT:
Method and apparatus for storing and retrieving loads increases usable warehouse storage space by allowing a load having a given length and width to be stored and retrieved from a narrow aisle while requiring less wasted space between adjacent stored loads. As a load is rotated 90.degree. preparatory to translating it into a storage space, the center of rotation is moved first in one direction along the aisle and then in the opposite direction. One corner of the load enters and sweeps across the initially empty storage space, and during a terminal portion of the rotation another corner of the load enters the storage space along a path having little or no component of motion in the aisle direction.
