Energy chains for long port crane service life

Tried and tested in thousands of applications; reduce costs, increase service life

Heavy loads, long periods of use, and a wide variety of weather conditions – cranes in port facilities must have fantastic performance. And that is just where our energy chains and flexible cables are being used. They have proven themselves for years in more than 10,000 ports with their corrosion-resistant, maintenance-free materials and long service life. The fields of application include, amongst 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.


New products in 2021

"Chains for cranes" next level: maximum service life for the latest generation of cranes

smart plastics P4.1

Predictive maintenance for heavy-duty applications ...

... with smart plastics in the new P4HD rol e-chain

▲ Tech up
  • Integration of condition sensor, including electronics, into the roller chain link
  • Monitoring abrasion at the pin/bore connection
▼ Cost down
  • Saves external energy supply with inductive "energy harvesting"
  • No additional cable in the chain due to connection via LoRa radio standard

System comparison

Energy chain systems instead of festooning, motor cable drums and busbars

Energy chains systems instead of festooning

Energy chain systems instead of festooning
Provide guidance for cables and energy chains whilst keeping them protected and safe in wind and fluctuating temperatures. That way, downtime can be reduced.

Energy chain systems instead of motor cable drums

Energy chain systems instead of motor cable drums
No slip ring on long travels. Guide all media safely in one system. Travels of up to 1,000 metres.

Energy chain systems instead of busbars

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 movement in lanes.  


Durable products for crane technology

Roller energy chains

Roller energy chains,
