ABSTRACT:
A warehouse crane comprises an elevationally positionable carriage, a shuttle guidably mounted on the carriage for transverse movement, and apparatus for moving a tote pan out of storage racks alongside either side of the crane and onto the carriage, the crane further being able to replace the tote pan in its original compartment or to place the tote pan in any other compartment in either of the storage racks. The apparatus for moving the tote pan out of a storage rack includes a pair of reversibly driven endless chain mechanisms mounted on the shuttle and a tote pan puller attached to those chain mechanisms. The puller travels in a horizontal and flat orbital path, but changes from a vertical position to a transversely outwardly inclined position as it approaches the ends of that path so that the puller may engage a tote pan handle as it moves upwardly in an inclined position.
