Energy chains, cables and heavy-duty bearings for port and intermodal cranes

Durable and networked products for long travel distances and high loads.

Why should I choose an energy chain for cable routing on a crane? With heavy cable loads, long operating times and a wide variety of weather conditions, cable guides in cranes have to deliver top performance. The energy chain for harbour cranes and intermodal cranes scores highly here thanks to its corrosion-free and maintenance-free materials and long service life.
In places where there is deadline pressure and yet safety during operation takes priority, energy chains therefore prove to be particularly reliable cable guides. Especially in comparison to busbar systems, festoonings and motorised drums, the low-maintenance and low-noise energy chains can prove their worth. More than 10,000 harbours already rely on the system.
On this page you will find an overview of our energy chain, cable and sensor systems as well as lubrication- and maintenance-free bearing technology for harbour cranes and intermodal cranes.

energy chain for harbour cranes and intermodal cranes

Unplanned downtimes must not occur at any time on harbour or intermodal cranes. This places particular responsibility on the cable routing on the crane. This is because a break in the trailing cable, the cable routed in an energy chain or a defect in the cable routing itself will inevitably bring the crane operation to a standstill.
At the same time, these systems must be able to handle heavy loads over travel distances of over 1,000 metres without any problems.
Such risks can be minimised with special energy chains for cranes. Thanks to the development of specialised solutions such as roller energy chains, even the longest travel distances can be achieved with low drive power. This also reduces wear and maintenance costs. And thanks to optional sensor technology, the safety of the chain and cable can be further increased.

P4HD - The e-chain® with the highest service life

The advanced P4HD energy chain has been developed for the next generation of container cranes. The roller chain is suitable for particularly long travel distances with high dynamics. Thanks to optional sensor technology (i.Sense and i.Cee), failures can be prevented before they happen.

The future of STS cranes and the energy chain

Triple-E container ships and STS cranes

STS cranes are changing. This is because ever larger container ships (Triple-E) will require even larger cranes in the future. You can find out exactly how this will affect STS cranes and the energy chain here.

cables for harbour cranes and intermodal cranes

Cables that run in the energy chain on the crane are subject to high mechanical stress, just like trailing cables. The long travel distances and tight bend radius inevitably lead to cable stress. For this reason, we test our chainflex® cables in 700 tests every day in our in-house test laboratory. This enables us to issue a 4-year guarantee on all cables. Incidentally, all our TPE cables come with UL approval and are UV-resistant.

chainflex control cables CF9 and CF10

In our control cable range, we offer the stability required for long travel distances on cranes thanks to different core counts, diameters and outer sheath materials.

chainflex motor cables CF37/38, CF330/340

Motorised cables must also always operate reliably and without failure. For example, when supplying the hoist on crane systems over long travel distances, under high mechanical stress and outside temperatures from -40° to +50°.

High-load bearings for harbour cranes and intermodal cranes

igutex® composite plain bearings consist of a robust glass fibre fabric outer shell and an inner layer optimised for optimum frictional behaviour. This makes them suitable for high loads and yet they are lubrication- and maintenance-free. Maintenance costs and the risk of incorrect lubrication can therefore be avoided.

User report: lubrication-free bearing in RTG chassis
Tan Cang Gantry relies on TX1 high-load bearings from the igutex® range in the chassis, the "bogies", of its RTG cranes. The TX1 bushes allow a surface pressure of up to 200 MPa. This gives the engineers at Tan Cang Gantry more flexibility in the design. At the same time, the resistance on the shaft is minimised, thus increasing the service life.

Sensors for harbour cranes and intermodal cranes

Sensors on the energy chain or the cables on the crane guarantee a high degree of safety and reliability, especially on long travel distances. On large structures and long energy chains, a cable break or defect in the energy chain is not quickly detected. Added to this is the maintenance time. On busy container terminals in particular, such failures can quickly become very costly. With the i.Sense and i.Cee sensors for monitoring and predictive maintenance of the chain or cable, such problems can be avoided.

i.Sense condition monitoring

The smart condition monitoring sensors from i.Sense are used to permanently monitor the operating status of moving components and can fulfil different functions depending on the application. In energy chains, they are used to monitor the <a 0="[" 1="o" 2="b" 3="j" 4="e" 5="c" 6="t" 7=" " 8="O" 9="b" 10="j" 11="e" 12="c" 13="t" 14="]" href="de-de/website/smart-maintenance/condition-monitoring/zustandsueberwachung-ec-p" uuid="462dbae7-87ae-480c-aab2-f6bb5bc277ab" target="_self">tensile/push forces (i.Sense EC.P) and <a 0="[" 1="o" 2="b" 3="j" 4="e" 5="c" 6="t" 7=" " 8="O" 9="b" 10="j" 11="e" 12="c" 13="t" 14="]" href="de-de/website/smart-maintenance/condition-monitoring/zustandsueberwachung-ec-b" uuid="1ad07707-9185-4a23-913b-ef280b57320c" target="_self">to identify chain breakages at an early stage (i.Sense EC.B).

i.Cee predictive maintenance

i.Cee Sensors continuously measure the clearance between the pin and hole of a chain link. Together with movement data from the system, this determines the expected remaining service life of an energy chain. If necessary, an automated warning is then issued to replace or maintain the chain. The result: more safety, lower costs.

Application examples. This is where customers rely on energy chain.

In the video, those responsible at the Port of Virginia explain why the port is relying on the energy chain for its new STS cranes. After equipping 8 STS cranes with e-chain® in one project, maintenance costs were reduced to a minimum while durability increased. Or as Jeff Johnston, responsible for maintenance at the Port of Virginia, summarises:

"[...] reliability, ease of maintenance and peace of mind."

Tested for use on cranes - in the industry's largest test laboratory

With travel distances of several hundred metres, we don't want to leave anything to chance. Our energy chains and cables are therefore subjected to daily endurance tests on special test rigs for sectors such as the crane industry.
