Robust energy chains and cables for the mining an bulk handling technology

In the area of bulk handling, equipment must function under tough and dirty conditions and work reliably even in bad weather. We offer polymer components for bulk handling which make that possible and are characterised by their robustness and long service life. These include energy chains, cables and hoses, which are used for example in bucket-wheel excavators, ship loaders, portal scrapers, wagon tipplers, conveyor belts, lifts, silos and funnels. The igus Project Engineering Team will assist you with the sizing, design, construction, project management, reconstruction, installation and commissioning on site.

Benefits of igus products:

Corrosion-free
Cost-effective, modular design
Durability with low maintenance
Resistant to dirt, sea water, chemicals, extreme temperature
Proven, tested material with igus system guarantee

Success stories

e-chain system for bulk goods technology in India

World record with 670m

Longest travel with rol e-chain system

For an international customer, our engineering teams in Germany and India have implemented the world's longest travel with an e-chain system. For years, the customer had recurring problems with the power supply, which was implemented by motor cable reels and ribbon cables on two bucket wheel excavators. This repeatedly led to production downtimes. After the installation of the new e-chain system with smart condition monitoring, the plant has been running perfectly.

Conveyor system in aluminium oxide production outdoor storage

Energy chains in aluminium oxide production outdoor storage

Reliable power supply in dusty and dirty environments

During the mining and subsequent storage of bauxite, a sedimentary rock for the production of aluminium oxide, a lot of dust is produced, which is a major challenge especially for the moving machine parts of the conveyor units. Partly for this reason, the Aluminum Oxid Stade GmbH (AOS), one of the major German alumina producers, decided to use energy chains of igus. For several years now, they have reliably supplied conveyor units and stockpiling equipment with energy, data and media.

e-chain system in Tušimice lignite power plant

Lignite excavator

In operation since 2008 without failure on a 615m travel

At the Czech lignite power plant Tušimice, coal is stored in a lengthy heap on the edge of the power plant site. To pile the coal automatically on the heap, a stacker is used. Originally, a cable reel was used for the power supply but the cables repeatedly froze in the winter, which led to system failures The operators switched to an energy chain system from igus. This has ensured a reliable operation without failure for many years.
