There is certain basic data that is required – the diameters, weights and minimum bend radius data for the cables and hoses. Also, the application data, such as machine travel length, speed, acceleration and even the environmental conditions. Service life calculations can be obtained with our online tool here.

At igus®, we have online expert systems to help offer the available options for these inputs and show respective lifetimes and costs.  Of course, we can also support by phoneemailLivechat and visits to your site by our engineers.

The longest in service now is a travel length of 615m, which has been running trouble-free for 10 years. We are confident we have the products that will reach 800m travels and beyond.

Use the e-chain® calculation tool here to configure the right energy chain system for your application.

igus® also offers a wide range of dynamically rated cables for use in constantly flexing applications (“chainflex®“), which are guaranteed for 10 million movements or up to 4 years when used as per our guidelines. These can be supplied with or without connectors and pre-fitted into the energy chains. We also offer steel and aluminium guide troughs for longer travels, cable clamping solutions for cable strain-relief and chain interior separation options to ensure a long cable life inside the chain.  We also offer design and project support, onsite services such as supervision and inspection and full turnkey installation.

igus® e-chains®, or energy chains, can cope with fill weights of up to 600 kg/m unsupported.

igus® can carry out offshore surveys on existing chains, and also offer full turnkey installation, or installation supervision, on any of our chains being installed offshore.

igus® e-loop has been designed to enable the operator to replace single cables/hoses in situ, rather than having to replace the full service loops. The e-loop is built up in links, which can be opened to allow the cables to be changed. The dyneema rope which runs through the middle of the e-loop is pre-tensioned to the working load, and so takes the strain of the cables or hoses in use.

Yes! igus® e-loop is supplied with an industry-standard mounting bracket and flange, as per on major OEM top drives, so it is a simple and quick retrofit!

igus® has thousands of energy chains on existing applications offshore including cantilever skids, pipelay towers, gantry cranes, and many more as seen here. Our polymer energy chains are maintenance-free, corrosion resistant, and cost effective vs equivalent steel chains.

igus® can carry out offshore surveys on existing chains/cable management solutions and retrofit them with a new maintenance free igus® energy chain! We offer a complete turnkey engineered solution to suit our customers’ requirements!

Although igus® does not manufacture hydraulic hoses, the hoses can be sourced and installed within your e-chain® to your requirements.

Our online tool prevents our customers from over filling the e-chains®. We have recommendations for the amount of clearance each service should have when installed within the e-chain® (relative to its OD); 10% for all round and flat cables, 5-10% for pneumatics, 20% for hydraulic hoses and 15-20% for all other media hoses.

Almost every industry with moving energy requires energy chainscranes, lifts, theatres, vessels, machine toolsrenewable energy systems, electronics, pick-and-place machines, telescopes, agricultureprinting, vehicle sliding doors, and so on – the list is endless.

No, a visual inspection is required every 6-12 months and adjustment of cable tensions (if necessary).

88% faster installation time than standard chain.

All igus® energy chain sensors (push/pull monitoring, abrasion, motion, wear measurement, break detection) can be connected to an icom or icom. plus module. The module can transmit the measurement data to an equipment monitor or a computer, where they are displayed individually or in a dashboard.

We have a configurator tool and a product finder tool which will help you specify the energy chain required.

Yes. We recommend the TH3 energy chain, which has been developed specifically for the food and beverage industry.

Yes, all igus energy chain materials can be deployed in continuous use at temperatures as low as -40 °C.

Yes, the autoglide system allows travels of up to 80 m without guide troughs.

Yes, plastic energy chains that use the igumid HT material can resist swarf as hot as + 850 C.

detailed list provides information on the resistance of igus’s igumid G, TE, and NB materials to many chemical substances.

As a rule, the standard temperature range for plastic energy chains is -40 °C to +130 °C, short term +170 °C.

The basis is the model 2400 with 77mm width and 75mm bend radius. Other widths and radii are of course also possible. Find out more about autoglide 5 here.

Yes, because the special crossbars can simply be opened. Should they ever wear out, they can be easily replaced.

As with all the igus® e-chains®, we aim for 10 million cycles or 10,000km. The tests for a guaranteed statement are still running in our laboratory.

You can discover the service life of igus® energy chains using the service life calculator.

The purpose of igus® cable drag chains are to guide and protect cables in moving applications. Find out more about our drag chains here.
