Harbour cranes | Indoor cranes | Shipyard cranes | Bulk goods cranes | Outdoor cranes
Harbour cranes
Heavy loads, long operating times, a wide range of weather conditions - cranes in harbour facilities have to deliver top performance. And this is exactly where our energy chain and flexible cables are used. They have been proving their worth in more than 10,000 harbours for years thanks to their corrosion-resistant, maintenance-free materials and long service lives. Applications include ship-to-shore cranes, bulk handling cranes, RTGs, RMGs, Goliath cranes, spreaders and reach stackers. Where there is deadline pressure and safety must be guaranteed, e-chain® is a reliable, low-maintenance and quieter alternative to busbar systems, festoonig and motorised drums.
Roller energy chain in continuous operation at the port of Rotterdam
A P4.1 series roller energy chain is in operation at the port of Rotterdam, one of the largest handling ports for bulk goods in Western Europe. Despite 24/7 continuous operation and a travel distance of over 100 metres, it works without incident on the huge ship-to-shore crane and has completed over 9,000 operating hours to date.
Container crane at the Port of Hamburg
Fourteen container gantry cranes at HHLA Container Terminal Altenwerder (CTA) have been equipped with energy chains to supply the gantry cranes with power and signals.

By replacing the old cable routing with our P4-energy chain, the crane's downtime has been increased, the chain now runs more quietly and wear has been significantly reduced.
To the application example
Roller energy chain on STS crane
For the high-speed trolley drive, a safe and failure-free roller energy chain was used for energy and data transmission.
To the application exampleIndoor cranes
They are designed for the overhead movement of loads within a building, e.g. in production and assembly halls: Overhead cranes. Low downtimes, low maintenance requirements and the functional safety of the system are desirable from an economic point of view, but also with regard to occupational safety. Our energy supplies are developed for different operating conditions, but also for the various standards of the international markets. Always optimally designed, as a complete system or individual component and with a predictable service life.
Heat and dust: energy chain for adverse conditions
In Thyssen Krupp's Duisburg hot rolling mill, a slab transport crane from BANG Kransysteme GmbH & Co KG is responsible for handling the slabs at the interface between the steelworks and rolling mill - in heat and dust. The energy and signal supply to the trolley and the cabin is ensured by "Heavy Duty"-energy chain from igus®, which were supplied as pre-assembled readychain® basic systems.

At the waste incineration plant in Eschweiler, the existing trailing cables were replaced by an energy chain that was developed for use in harsh environmental conditions.
To the application example
Chemical-resistant indoor crane
Plastic energy chain systems for supplying energy to the process cranes have been proving their worth in this hot-dip galvanising plant under high acid loads for several years.
To the application example
Indoor cranes in a foundry
These three cranes are used to transport containers of molten metal in a foundry. The hot environment and high levels of contamination placed special demands on the cable routing.
To the application example
Indoor crane in metal processing
Our e-chain® really comes into its own in this indoor crane application: Even under the heavy load of dust and hot metal chips, there have been no failures in three years.
To the application example
Coil crane in steelworks
The motorised cable drums on this coil crane required a great deal of maintenance. They were therefore replaced by our e-spool® system.
To the application example
Overhead crane in steelworks
This crane transports billets in a steelworks using a magnetic lifting beam. To supply power to the slewing gear, the developers used an e-chain® from the triflex® series instead of the previous conductor rail.

In a waste disposal company in Belgium, the trailing cables in two travelling cranes have been replaced with our e-chain®.
To the application example
Overhead cranes in concrete plant
In the harsh environment of concrete processing, energy supply contributes to the stability and reliable operation of indoor cranes.
To the application example
guidefast system for overhead crane
The manufacturer Piedmont Hoist and Crane in the USA opted for the convenient guidefast modular guide trough system for an overhead crane.
To the application exampleShipyard cranes
Shipyard cranes are usually characterised by their high load capacities and long travel distances of the trolleys, which can easily reach up to 200 m in length. With high cable weights, the energy chain must always work reliably and protect the guided cables. At the same time, compact and space-saving solutions are also required, especially in shipyards.
To meet these requirements, we offer our customers a comprehensive portfolio of heavy-duty energy chains, cables and guide troughs for long travel distances and high weights.
Roller energy chain replaces cable tender on Goliath crane
For this 900 tonne shipyard crane, the operator previously relied on a cable tender system to guide the cables to the trolleys. As the tension on the cables led to high maintenance requirements over time, the decision was made to replace it with an energy chain system. Since then, two heavy-duty roller energy chains from the 5050RHD series have been in use.
Fast and safe conversion at a height of 122 metres
At the Navantia shipyard, the old Goliath cranes had to be repaired after 40 years of operation. The former line rope tender system was replaced with a modern energy chain system within a very short space of time.

To the application example
Reliable even during typhoon storms
Three shipyard cranes are currently in operation at the southern harbour in the Pudong area of Shanghai. The energy and data supply to the gigantic lifting elements is realised via our plastic energy chain systems.
To the application exampleBulk goods cranes
Bulk goods cranes place extreme demands on cable solutions in many respects: While the transport routes for bulk goods can be several hundred metres long, all components must be able to withstand outdoor weather conditions all year round. However, the high dirt and dust load when transporting ore, sand or gravel, for example, also requires energy chains that are highly robust, corrosion-resistant, maintenance-free and have a long service life.
e-chain® defies dust and dirt when mining bauxite
A lot of dust is created during the mining and subsequent storage of bauxite, which poses a major challenge, especially for the moving machine parts of the conveyor units. The operator therefore decided to use our plastic-energy chains. They have been reliably supplying conveyor units and stockpiling equipment with energy, data and media for several years now.
plastic-energy chain in steelworks
In this steel factory, a plastic-energy chain replaces a previously used vulnerable metal chain at the unloading station for raw metal and scrap metal.
