What began as a relatively limited engineering assignment has grown into a major modernization of the hydraulic systems as part of the renovation of the Krammersluizen. As the hydraulics partner within the ZEEKR consortium, Bosch Rexroth is responsible for the hydraulic systems in the project: from the roller doors of the push-boat locks and the swing gates of the yacht locks to the slide gates and the new spillway fish passage.
Demako is part of a select group of companies that focuses entirely on the mechanical engineering systems, mechanics, and moving parts of movable bridges and locks. That specialized expertise is fully put to use in the renovation of the Krammer Locks: from drive systems and leveling systems to gates, valves, and roller carriages. All components that determine whether the lock operates safely and reliably fall within the company’s scope. According to Demako’s specialists, this is the “Champions League” of mechanical engineering.
At first glance, replacing a lock gate seems like a simple matter of removing and reinstalling it. The reality is considerably more complex—especially at the Krammer Locks, where the gates weigh anywhere from 65 metric tons to as much as 400 metric tons. For De Klerk, these gate replacements represent the culmination of years of involvement with the complex, where the company has been active almost continuously since 2015, carrying out maintenance, renovation, and overhaul work.
