Examples of successful applications in the crane industry

Port Cranes

Heavy loads, long periods of use, and a wide variety of weather­­conditions – cranes in port facilities must perform at their best. And that is exactly where our energy chains and flexible cables are being used. They have proven themselves for years in over 10,000 ports with their corrosion-free, maintenance-free materials offering a long service life. The fields of application include, among others, ship-to-shore cranes, bulk cargo handling cranes, RTGs, RMGs, Goliath cranes, spreaders and reach stackers. Wherever safety must be ensured and there is pressure to meet deadlines, e-chains® are a reliable, quiet alternative to busbar systems, festooning and cable drums.

Lubrication-free heavy-duty bearings in RTG cranes

The Vietnamese manufacturer Tan Cang Gantry relies on completely lubrication-free and maintenance-free TX heavy-duty bearings in the chassis of its new RTG cranes.

Container crane Hamburg Port

Fourteen container gantry cranes at HHLA Container Terminal Altenwerder (CTA) are equipped with energy chains to supply the gantry trolleys with energy and signals.

STS crane Antwerp

For travels of more than 400 metres in some cases, 12 ship-to-shore cranes in Antwerp were equipped with robust heavy duty energy chains.

Container loading crane

Since this port is located in the immediate vicinity of a residential area, a crane was equipped with the fail-safe and low-noise P4 roller energy chain.

Ship unloading crane

For the crane boom of this STS crane, e-chains replace the previously used festooning system and save the operator time and money.

Bridge crane

By replacing the old cable guide with our P4 energy chain, the service life of the crane has been increased, the chain is now running more quietly and wear has been significantly reduced.

Roller energy chain on STS crane

For high-speed trolley drive, a safe and failure-free roller energy chain was used for energy and data transmission.

Indoor cranes

They have been designed for the overhead moving of loads within a building, such as in production and assembly areas: gantry cranes. Short downtimes, low maintenance requirements and the functional reliability of the system are important from an economic point of view, but also with regard to occupational safety. Our energy supply systems have been developed for different operating conditions, but also for the various standards of the international markets. They are designed in an optimal way, as a complete system or individual component, and with a predictable service life.

Crane in cement plant

With this crane system for storing and removing sewage sludge in a cement plant, an energy chain has proven itself through flexibility, variability and space-saving installation.

Indoor crane: 50% more storage space

This indoor crane had an extremely low clearance height. Our pre-assembled energy chain solution created 50% more storage space.

Chemical-resistant indoor crane

Plastic energy chain systems for supplying energy to process cranes have proven themselves for several years in this hot-dip galvanising plant under high acid loads.

Indoor cranes in the foundry

Containers containing liquid metal are transported in a foundry using these three cranes. The hot environment and high levels of contamination placed severe demands on the cable guidance.

Indoor crane in metal processing

In this indoor crane application, our e-chains show their advantages: even under the heavy load of dust and hot metal swarf, there has been no failure in three years.

Coil crane in steelworks

In this coil crane, the motor-driven cable drums required a high level of maintenance. That is why they were replaced by our e-spool system.

Bridge crane in steelworks

This crane transports billets in a steel mill using a magnetic beam. For the power supply of the slewing gear, the developers are using a triflex series e-chain instead of the previous conductor rail.

Garbage crane

In a waste disposal company in Belgium, the trailing cables were replaced by our e-chains in two travelling cranes.

Gantry cranes in concrete plant

In the harsh environment of concrete processing, energy supply systems contribute to the stability and reliable function of indoor cranes.

guidefast system for gantry crane

The manufacturer Piedmont Hoist and Crane in the USA opted for the convenient guidefast modular guide trough system for a gantry crane.

70m crane track in waste incineration plant

In the Eschweiler waste incineration plant, the existing trailing cables were replaced by an energy chain that was developed for use under adverse environmental conditions.

Shipyard cranes

Shipyard cranes are usually characterised by their high load capacities and long travels of the trolleys, which can easily reach up to 200m in length. With heavy cable weights, the energy chains must always work reliably and protect the routed cables. At the same time, compact and space-saving solutions are also in demand in shipyards in particular.
To meet these requirements, we offer our customers a comprehensive portfolio of heavy duty energy chains, cables and guide troughs for long travels and heavy weights.

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. Within a very short time, the previous cable tender system was replaced by a modern energy chain system.

Energy supply at 61kg/m cable weight

For a single-girder goliath crane, two trolleys were equipped with our roller e-chains and chainflex cables. One of the energy chains moves a cable weight of 61kg/m.

Roller e-chains for 1500t shipyard crane

Specifically designed for large-sized projects, the two heavy-duty roller energy chains reliably supply two trolleys with energy - over a travel distance of 122m.

Supply of 16 trolleys for Goliath crane

16 crane trolleys travel on this gigantic Goliath crane with a load capacity of 15,000 tons. Our roller energy chains ensure safe cable guidance.

Functionally reliable even in typhoon storms

Three shipyard cranes are currently in use at the southern port of Shanghai's Pudong area. The energy and data supply to the gigantic lifting elements is implemented via our plastic energy chain systems.


Bulk handling cranes

Bulk handling cranes place extreme demands on cable solutions in many respects: while the travels for the transport of bulk goods often reach several 100 metres in length, all components must withstand outdoor weather conditions throughout the year. But also the high level of dirt and dust during transport of, for e.g., ores, sand or gravel require energy chains with high robustness, corrosion resistance, maintenance-free and long service life.

Plastic energy chain in steelworks

In this steel factory, a plastic energy chain replaces a previously used vulnerable metal chain at the unloading station of raw metal and metal scrap.

Ship loader in the Baltic Sea port of Wismar

In the course of the conversion measures at the Baltic Sea port of Wismar, a ship loader that was previously used exclusively for loading potash was converted for handling different bulk goods.
