Abstract
An overhead traveling vehicle and the local carriage each includes a hoist and travel directly over load ports. The track for the local carriage includes a pair of rails directly under a track for the overhead traveling vehicle, and articles vertically pass between the pair of rails using the hoist of the overhead traveling vehicle. A sensor detects an article that is horizontally swinging in a direction perpendicular or substantially perpendicular to the lengthwise direction of the track for the local carriage in the horizontal plane and is provided at least at a position that is under the track for the local carriage and outside of the raising and lowering path of an article that is not horizontally swinging. The overhead traveling vehicle and the local carriage stop the raising and lowering of the hoists when the sensor detects an article that is horizontally swinging.
