This crane in a truck assembly plant is used to unload and transport the individual vehicle chassis at the beginning of the assembly process. Since a large number of cables are required, two energy chains® running in opposite directions were placed in one guiding trough. Furthermore, a zigzag solution is used here. The deployed igus® E-Chains® of the E4 family guarantee very high availability of the facility so that the production of new truck can be started up on an average of every seven minutes.
