Reliable e-chains® for RTG/RMG cranes
Proven Effectiveness Worldwide: Over 7,000 RTG/RMG Cranes and Counting!
Rubber-tired gantry cranes (RTG) and Rail mounted gantry cranes (RMG) are designed to handle containers efficiently in tight spaces, boasting large spans and lifting heights to stack numerous containers. To address the challenges associated with such operations, we offer heavy-duty roller energy chains. These energy chains play a crucial role in reducing the required drive force during long travels, enhancing the overall reliability of the crane system. In addition to our energy chain systems, we provide a comprehensive selection of supplementary products tailored to meet your specific requirements. Our offerings include guide troughs, floating moving ends, clamps for strain relief, and TPE cables designed to meet the highest demands. By combining these components, we deliver an optimal complete package for your crane solution.

Condition monitoring with i.Sense
The intelligent i.Sense sensor system and software monitors the condition of the energy chain on the crane around the clock. While heavy loads, long operating times and severe weather mean high loads for RTG/RMG cranes, i.Sense helps to ensure operational safety. In the event of problems, the software can initiate an emergency stop to prevent major damage.Learn more
Cables for RTG/RMG cranes
In port operations, lines are severely strained. In industrial trucks that operate continuously at container terminals, they will often be on the move around the clock. To ensure that there are no wire breaks and that the cables achieve the longest possible service life, we test all our chainflex® cables extensively in advance in our in-house test laboratory with a total area of 3,800 m². All our cables are also UV-resistant, come with a UL-certified version and receive a flat-rate warranty up to 4 years.Learn more
New e-chain for crane trips of more than
1,000m travel distance
- First driven cable guidance for the next generation of RTG/RMG cranes
- Thanks to own drive, there is hardly any stress due to push/pull forces
- Higher acceleration & speed possible due to lower mass

System Comparison:
Energy chain systems instead of festooning
Provide guidance for cables and energy chains while keeping them protected and safe in wind and fluctuating temperatures. This minimizes downtime.
System Comparison:
Energy chain systems instead of busbar systems
Deliver data, energy, fluids and air safely in a single energy chain system. For narrow compact spaces and fast lane movement.

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 bulk handling ports in Western Europe. On the ship-to-shore crane, it operates continuously over 100 metre travel and without incident. So far it has completed more than 9,000 operating hours.
