A motion direction and a speed of a hoist carrying a module or an article in a space above the conveyor are synchronized with a motion direction and a speed of the article being conveyed by the conveyor. Specifically, a rail from which the hoist is suspended and disposed over the conveyor has a movable construction, and using a motion of this rail and a motion of the hoist, the motion direction and speed of the hoist is synchronized with the motion direction and speed of the article. |
