Think big with the world's largest plastic energy chain from igus29/08/2016
Even in steel plants, the use of steel in operating equipment is not always the first choice, especially when it comes to a reliable and robust energy supply system. The E4.350 energy chain was designed by the motion plastics specialist igus for those industries where large cables and hoses must be protected, such as for heavy duty machinery or offshore applications such as ship cranes or drilling platforms. The high-performance plastic ensures that the e-chain is resistant to corrosion and insensitive to chemical and petrochemical influences as well as resistant to sunlight. The material is self-lubricating and requires no grease or oil on the joints throughout its service life, even in very dirty environments. This reduces the need for routine maintenance and enables a more accurate prediction of the service life of the energy chain.
Individually customisable to the application
Having a modular structure, the E4.350 can easily be lengthened and shortened, as required. For unsupported lengths up to 6.5 m and fill weights over 100 kg/m, the igus energy chain provides excellent rigidity and very high load capacity. The strong crossbars along with the enormous interior height of 350 mm provide for an easy filling of the e-chain with very large cables and hoses. A big advantage over energy chains made of steel is not only their lighter weight, but also its ability to be very easily custom filled, thanks to a separation system with interior fixtures and mounting brackets in every chain link, The E4.350 is also available as a rol e-chain for very long travels: rollers made of special tribopolymers create a nearly maintenance-free operation, significantly reducing wear and tear of the chain, thereby increasing the service life of the application. Since the coefficient of rolling friction is by around 75 percent less than the coefficient of gliding friction, up to 57 percent less energy is needed to drive the chain. The E4.350 is available as a single component and as a fully-assembled system, and on request can also be installed directly on site anywhere in the world.
As strong as steel but significantly lighter
Extensive testing in the 2,750 m²-large test lab shows how strong the energy chain is. The result showed that the E4.350 withstood tensile and breaking loads of well over 175,000 N without problems. But the e-chain has proven itself even in actual use in many applications worldwide, in ships, offshore platforms as well as at the port of Antwerp. There, dredged water from the harbour is passed into a basin and the silt is drawn by pumps on the bridge. The pumps can be moved across the entire bridge length of 150 metres. The heavy hoses (around 100 kg/m) are guided safely with the E4.350 and protected against mechanical abrasion on the bridge. The entire system runs maintenance-free around the clock.
