Abstract
An overhead transport vehicle includes a gripping unit to grip an article, an suspension unit by which the gripping unit is suspended, a drive unit that reels up the suspension unit to thereby raise the gripping unit, a detection unit to detect swing of the gripping unit, and a controller that controls the drive unit to reel up the suspension unit and store the gripping unit into the transport vehicle body. In reel-up control to reel up the suspension unit, when swing of the gripping unit exceeds a predetermined width, the controller stops reeling up the suspension unit, maintains the gripping unit at a standby position lower than a storage position, and then, reels up the suspension unit when the swing of the gripping unit becomes equal to or less than the predetermined width.
