1. In a warehousing system having a plurality of load storing means, rail means extending along and fixed with respect to said load storing means, carriage means movable along said rail means and including load carrier means for depositing and retrieving loads from adjacent load storing means, and drive means for moving said carriage means including drive slowdown means actuable to decrease the speed of said carriage means in anticipation of reaching a selected load storing means and drive stop means actuable to stop said carriage means at the selected load storing means, the improvement comprising:

  • a plurality of separate address means mountable at different spaced locations on said rail means for uniquely identifying slowdown and stop positions for each of said load storing means, each separate address means including coded slowdown indicating elements for identifying the slowdown position at which said drive slowdown means should be actuated and coded stop indicating elements separate and spaced from said slowdown indicating means for identifying the stop position at which the drive stop means should be actuated when the load carrier means is to service the load storing means associated therewith, each separate address means further including control elements for modifying the operation of the drive means for the same address as identified by the indicating elements;

    interleave means for mounting said separate address means at desired spaced locations along said rail means with at least one of said coded slowdown indicating means being mounted to said rail means at a location between the coded slowdown indicating means and the coded stop indicating means for a different load storing means;

    plural sensor means mounted to said carriage means and movable adjacent said rail means for detecting said indicating elements and said control elements;

    control means responsive to detection of the coded slowdown and coded stop indicating elements in conjunction with the control elements associated with the selected load storing means for actuating the drive slowdown means and the drive stop means, respectively.
