Situation

Renovation and maintenance

When in the thirties of the last century the Bridge across the North (Alblasserdam, NL) was built, the authorities were still convinced that this bridge would have to be opened only seldom. Nowadays it is opened about 2000 times a year. In most cases for recreational sailing. In 2012 our customer performed major renovation and maintenance work on the movable component - the roll bascule. And now the national monument is ready for the next 30 to 40 years.

Smooth operation

Renovation and maintenance

Our Service Department first did the neccessary repair work on the custom made lock-nut cylinders that were being used to lift the bridge part. Then they were tested in accordance with the CertiSafe® procedure. During this project our customer also used Holmatro pumps, hoses and manifolds. The collaboration made sure that this part of the renovation works was carried out within the established schedule of one month. And any unforeseen emergency repair was being prevented.
