Maintenance-free E4.350 for offshore platforms

When the drilling rig is moved on to an oil platform (rig skidding) the plastic energy chains will be able to move 15 metres up and down during the drilling head stroke (top driving). This guarantees the heavy hydraulic cables are guided and protected. igus® presented the E4.350 energy chain® at the Hanover Fair for many such tough tasks in conditions dominated by ice, wind, storm, salt water, oil and drilling mud. The energy chain has an internal height of 350 mm and a variable inner width of 200 mm to 1 metre, giving a large internal capacity. Large cables and hoses with a diameter of up to 300 mm are guided stably by the plastic chain, with a potential fill weight of more than 100 kg/m.

High rigidity and service life
The special design of the E4.350 ensures extremely high torsional stiffness and stability. Thanks to an interlocking tongue and groove bolted joint, the links move easily. Additionally, special inner/outer link design ensures a straight run and quick assembly, especially when compared with the steel alternatives. Integrated sliding surfaces, larger wear surfaces and particularly strong stop-dogs ensure a very long service life. Even gliding use is possible for very long travel distances. Centre links increase stability even more and make it possible to extend the width of the energy chain almost without limit. Other special designs are possible. Finally, there is a comprehensive, easy to assemble, modular range of accessories including internal cable separation and shelving parts

Lubricant-free, failsafe and lighter
Firstly, the new E4.350 brings safety to extreme applications on oil platforms or in steel works, where cables can still often be found hanging loose without any kind of guidance or protection. Secondly, the lubricant-free plastic chain does not require any maintenance. Finally, the chain also offers a weight and cost saving for the machine. The E4.350 series will be available in 2009.
