Currently, an electric rail transport system (EMS) is widely deployed in a final assembly shop in the automotive manufacturing industry. The method is often applied to chassis lines and door lines of a final assembly workshop of a passenger car factory, and realizes the transportation and process assembly functions of heavy-load parts such as doors, car bodies and chassis by cooperating with a process module of AGV & Skillet skateboard lines.
