PROBLEM TO BE SOLVED: To lighten and simplify a mobile facility and promote the trend toward its high speed. SOLUTION: This mobile facility is provided with a travelling range finding device 51 for measuring the distance to a stacker crane 3 optically by means of a travelling range finding sensor 51a arranged in the reference measuring point P between the stacker crane 3, which can move on the fixed path along a travelling rail 4 and a ceiling rail 5 and a reference measurement position P, which is set on the ground side, a lift table 26, which can move on the stacker crane 3, a lifting range finding device 52 for measuring the distance from a lifting range finding sensor 52a, which is arranged in a reference measurement position P, which is set on a fixed side, to the lift table 26 through reflectors 52b and 52c on the lift table 26 between the reflectors 52b and 52c and the reference point P, and a ground side controller 11 for calculating the positions of the stacker crane 3 and the lift table 26 from the distance data obtained from the travelling range finding device 51 and the lifting range finding device 52.
