Abstract: A dual track conveying system for transporting workpiece carriers, has a main conveyor and, an auxiliary conveyor arranged parallel to the main conveyor. At least one transverse conveyor is arranged between the main conveyor and the auxiliary conveyor. The transverse conveyor is pivotally attached to the main conveyor. The moveable end of the transverse conveyor pivots up-and-to transfer the workpiece carriers from the transverse conveyor to the auxiliary conveyor. The transverse conveyor has a short belt and a long belt. The short belt is shorter than the long belt by the width of the auxiliary conveyor. A passive conveying track section following the path of the short belt is located in between the belts of the auxiliary conveyor to support one end of the work piece carrier when the moveable end of the transverse conveyor is in the raised position.
