Zusammenfassung:	Warehousing system apparatus has a storage rack with several vertically and horizontally related storage elements. A mast is moved horizontally on rails parallel to the face of a storage rack, and a platform moves vertically along the mast in response to signals from a three-brush signal wire pickup on a control wire strung along the rack. Vertical and horizontal hydraulic drives and controls are independent so that the platform may fly or move diagonally in the shortest line between locations in the storage rack. Electric motors constantly operate hydraulic pumps; pump output is controlled by stepping motors having telemetering switches to indicate pumping direction. A positive neutral band is provided in the hydraulic system for better drive control. A carrier which is driven from the platform into the rack has a cam means to change the position of load-driving lugs each time the carrier is driven to a maximum displacement from the platform.
