According to igus, energy chains and specialist flexible cables are gaining in popularity for crane applications, offering a low-maintenance alternative to bus bar, festoon and reel systems
igus E-Chain energy chain systems and Chainflex flexible cables are in operation in more than 5000 port equipment applications worldwide, including ship-to-shore cranes, bulkhandling cranes, RTG (rubber tyred gantry) cranes, RMG (rail mounted gantry) cranes, Goliath cranes, spreaders and even reachstackers.
Indeed, igus says that its power chain systems are becoming a popular alternative to bus bar, festoon and reel systems. Furthermore, igus has developed a wide range of complementary products that meet the specific needs for cranes applications, such as Micro Flizz, Invis, guide troughs, Guidelok (both horizontal and vertical) and ready chains
For crane builders and users alike, igus products solve many of the common design problems: they are space-saving, in a large part because no additional drives or control systems are necessary, and the igus systems can convey all types of media including power, data, air and water. As with all igus products, they are virtually maintenance-free and offer quick and easy cable installation and replacement. In addition, all igus products are wind- and weather-resistant and guaranteed for a long operating life.
