[Design study] drive-chain 2.0

Extreme dynamics and very long travel distances with a wear-free drive

The world's first energy chain system with its own drive, now almost wear-free with a linear motor. For very long travel distances (1,000m and more) with extreme dynamics and long operating times. For next-generation ASCs (automated stacking cranes). The lower mass allows higher acceleration and speed, and the drive-chain 2.0 also offers a much longer service life than do standard energy chain systems.

Tech up

Tech up

  • Virtually wear-free linear drive for even less friction over very long travel distances
  • Drive force does not have to come from the powered system (e.g. crane), because the e-chain system has own drive
  • Two drive concepts (linear drive & friction wheel drive)
  • Significantly higher operation times because there is almost no stress caused push/pull force
  • For ASC (Automated Stacking Cranes) next generation cranes
  • Higher acceleration & speed possible due to lower mass
Cost down

Cost down

  • Significantly longer service life compared to standard energy chain systems
  • Shorter cable lengths, due to central feed, resulting in lower cable costs when purchasing


  • Test setup in the igus laboratory


  • 4 - 6t less moving mass on the crane, thus less energy consumption
  • igus® has been an investor in Mura Technology from the very beginning and is advancing chemical recycling. From plastic waste to crude oil in 20 minutes.


ASC cranes Version with motor cable drum. Approximately four to six tons of weight, which must be carried permanently and costs drive force.


ASC cranes with drive-chain Version with igus drive-chain. e-chain system with its own drive force. Higher speeds and longer travels possible.

Energy chain systems for cranes

Energy chain systems in cranes Energy chain systems and flexible cables are used in cranes. They have proven themselves for years in over 10,000 igus® energy chain solutions in ports with their corrosion-free, maintenance-free materials offering a long service life.

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.
