An overhead traveling vehicle (4) is prevented from mistakenly detecting a track (10) for a local carriage (8) or the like as an obstacle. The overhead traveling vehicle (4) includes a hoist (22) and a first sensor (38) that monitors obstacles below, and the local carriage (8) includes a hoist (27) and travels along the track (10). A buffer (12) is suspended from the track (10) by vertical supports (32) that extend vertically downward, and no members of the buffer (12) are provided directly over load ports (16, 17). A second sensor (36), which monitors an obstacle that is in a vicinity of the load ports (16, 17) and in a passageway-side area on a side opposite to a processing device (13), is provided on the track (10) and transmits an obstacle detection signal to the overhead traveling vehicle (4) and the local carriage (8). Upon receiving the obstacle detection signal from the second sensor (36), the overhead traveling vehicle (4) and the local carriage (8) stop the hoists (22, 27), and the overhead traveling vehicle (4) does not monitor obstacles in the passageway-side area using the first sensor (38).
