The cargo of the present invention is a columnar product workpiece, which is used for processing a product, and the product workpiece can be transported to a predetermined processing position by moving back and forth on the slide rail 101 by the RGV shuttle 102. In other embodiments, the cargo may be objects of other shapes, and is not limited herein.

In actual operation, the two ends of the carrying platform 31 are connected with other conveyor belts, and goods conveyed by the conveyor belts can be taken on the vehicle under the driving of the rollers 38. As the RGV shuttle 102 moves on the skid 101, the goods can be transported to a designated location, and then transferred to the designated location by the rotation of the rollers 38.
