igus® application examples

Lock gates

Salt water resistance and compensation for sideways motions for lock-gate operations.

Roller energy chain on ship unloaders over 400m travel

On a 441.3 m travel, a roller energy chain reduces the drive power by 75%

OpenHydro tidal turbine

A plastic chain makes any kind of maintenance on the open sea obsolete; a conventional metal chain would not be adequate for the combination of technical, climatic and mechanical requirements.
