Solution
In view of the requirements, the igus® technicians recommended a roller
e-chain® of type 5050RHD for the energy and signal supply on the crane bridge. The chain system used for "heavy duty" applications is characterized by reinforced side parts, additional wear surfaces and a pin-hole system that has been reinforced by about 40 percent. As a result, cable weights — in this case 13 kg/m — can be guided and moved reliably. The chain length in this case is 17.8 m, with the system travelling a distance of 15.5 m. In addition
cables of the chainflex® product range from igus® were used. A TPE jacket ensures that all cables can withstand the high temperatures in the system.
Based on the special requirements for energy chain and cables, the chains were designed and supplied as
pre-assembled readychain® basic systems. The cables have been inserted but have not been completely pre-assembled or fitted with connectors. Plug-in connectors are unnecessary because the cables are connected to terminals. In addition, the cable lengths for such a special project cannot be determined down to the centimeter. Flexibility is more important in the assembly. Only the fiber optic cables (FOC) were harnessed with connectors in advance.
