Energy chains and cables for long service life of crane systems

Heavy loads, long travels and extreme weather conditions are just a few challenges for crane systems: where deadlines are still tight and safety must always be guaranteed, e-chains are a reliable alternative to busbar systems, festooning and motor drums with less maintenance and noise. With the right energy chain, a coordinated and reliable solution can be found for every application scenario.
Whether indoors or at the port, for bulk goods or container handling - all our products have been developed according to one motto: Tech up, cost down!

igus blogs: Intelligent energy chains on crane systems thanks to smart plastics


Successful application stories in the crane industry

Indoor crane

Fifty percent more storage space

An exceptionally space-saving solution has been developed for the energy supply system of a fully automatic crane system, which has proven itself under the highest loads and in continuous operation - and which today creates 50 percent more storage space.

STS crane

Reliable despite continuous operation

A roller energy chain is in operation at one of the largest bulk handling ports in Western Europe. On the massive ship-to-shore crane, it operates without incident despite continuous operation and over 100 metres of travel.
