The conveying system is incorporated in automobile assembly line, and comprises an overhead conveyer, a shuttle conveyer, a lift for carrying a work from the overhead conveyer to the shuttle conveyer, a lift controller and a shuttle controller. The shuttle conveyer carries the work from the lift to its destination. The lift controller controls the operation of the lift, which is reciprocated vertically according to the position of a shuttle member of the shutter conveyer. The shuttle controller controls the operation of the shuttle conveyer depending upon the position of a movable work holding base of the lift. A plurality of detectors are provided so as to detect the positions of the movable work holding base of the lift and the shuttle member of the shuttle conveyer, so that the conveying system can reliably operate without the interference between the lift and the shuttle conveyer.
