After its festoon systems began to fail as a result of corrosion, a manufacturer of lifting equipment mainly used in paper mills decided to use Igus Energy Chain cable carriers on its gantry cranes.

An Energy Chain system is mounted horizontally on each machine, where it guides and protects more than 75m of power cables.

The cable carriers deliver a longer service life than the festoons in the dusty, humid environment found in paper mills.

As well as accommodating high ambient temperatures, which can peak at 50C, these are accompanied by up to 100 per cent humidity levels.

Igus Energy Chains feature crossbars to facilitate access to the cables and can be opened using a screwdriver or by hand.

In contrast to a festoon system, which allows the cables to move around in an uncontrolled way, the Energy Chain system offers excellent protection and stops the cables from moving around and catching onto other equipment or structures.

This results in a reduction in downtime and also eliminates the corrosion problems associated with festoon rollers and trolleys.

Igus delivered the cable carriers as Readychains – pre-assembled, out-of-the-box systems complete with Energy Chain cable carriers, Igus Chainflex continuous-flex cables, connectors and other accessories.

The Readychains saved the customer time and eliminated storage costs.

Plastic Energy Chain cable carriers are said to be capable of long and short travel distances at high speeds in all orientations.

They can be used in a variety of applications, ranging from machine tools and construction equipment to packaging machines, medical devices and clean-room applications.

Igus

Igus is the largest producer of reinforced plastic energy chains and injection-moulded polymer bearings. The range of polymer bearings includes Iglidur plain, Igubal spherical and Drylin linear bearings. They offer an excellent price-to-life relationship and are developed under the toughest conditions. They are oil, maintenance and lubrication free, low wear, resistant to dirt and dust, corrosion free and simple to fit. Igus also has the data to precisely predict the lifetime of these bearings within a specific application.

Energy chains are the umbilical cord of modern machines. They minimise downtime and protect, support and extend the service life of cables and hoses. The broad range incorporates more than 30,000 innovative, low-cost products. From the smallest ‘micro’ chain to the largest chain in the world, the E4.350, Igus energy chains are capable of long and short travel distances at high speeds in all axes.

Igus also has its own cable series, Chainflex, specially designed with energy chains in mind. They are highly flexible cables, offering a long service life and very small bending radii. A wide range is available, from small signal cables to large power cables, high-speed data cables and glass fibre-optic cables.

The company’s energy chains and Chainlflex cables can be delivered as a fully harnessed and pre-assembled Readychain system, cutting purchasing, warehousing and installation costs.
