Zusammenfassung: | An article transport facility includes a plurality of transport vehicles, a first traveling rail, a second traveling rail below the first traveling rail, a lifter including a lift rail, and a control system. In response to a preliminary request signal from a target transport vehicle, the control system performs a preliminary lifting process of moving the lift rail to a target position when no non-target transport vehicle is on the lift rail and no entry request signal is received from a non-target transport vehicle. |
