Here, the second largest lock in the world has been fitted with a new water gate. The old tender system was no longer sufficient for the increased energy requirements. The system is housed in a water-flooded bunker and exposed to sea weather conditions. The 60 metre water gate is pulled into this bunker An igus® energy chain of the series 4040RHD is used for this application. There have been no problems with operation whatsoever so far, even at temperatures below freezing.
