ABSTRACT:
A travel distance-measuring unit measures optically a distance to a stacker crane by a travel distance-measuring sensor provided at a reference measuring position between the stacker crane that can travel on a predetermined route along a travel rail and a ceiling rail and the reference measuring position set on the ground side. A lift distance-measuring unit measures optically a distance to a lift table by a lift distance-measuring sensor provided at the reference measuring position via reflectors between the lift table26provided movably to the stacker crane, the reflectors provided to the lift table, and the reference measuring position P set on the fixed side. A ground side controller calculates a position of the stacker crane and a position of the lift table based on distance data derived by the travel distance-measuring unit and the lift distance-measuring unit.
