Automated Central Lubrication on the Hadsund Bridge

Client: Danish Road Directorate (Vejdirektoratet)
In cooperation with: Cowi
Location: Hadsund Bridge, Mariagerfjord Municipality

Background and Need
The Hadsund Bridge is an important traffic connection, used daily by both vehicles and vessels. The bridge is remotely operated from Aalborg, and as part of a broader modernization project, the Danish Road Directorate wanted a solution that could reduce the need for manual maintenance while increasing operational reliability and efficiency.

Previously, lubrication of the bridge’s moving parts required a full working day once a week from an on-site employee. To future-proof the bridge and minimize manual maintenance, it was decided to establish a central lubrication system – a solution that automatically ensures correct lubrication of all critical components.

The Solution
 
Serman & Tipsmark was chosen as supplier of the new lubrication system and was responsible for:
• Delivery and installation of grease pumps and distribution blocks for the individual lubrication points
• Piping and installation on the bridge structure
• Close collaboration with Cowi on planning and execution
 
Due to the complexity of the installation, parts of the work had to be carried out at night, when the bridge was temporarily closed to minimize inconvenience for road users. Our experienced service technicians maintained full focus on both safety and precision throughout the process.

Results and Benefits
With the new automatic central lubrication system, the Danish Road Directorate has achieved:
•  Increased operational reliability and reduced downtime
• Consistent and correct lubrication – every time
• Reallocation of resources previously tied up in manual maintenance
The solution is an important step toward a more automated and maintenance-friendly infrastructure – benefiting both authorities and bridge users alike.

Statement

"The collaboration with Serman & Tipsmark has been excellent throughout the entire project.
Technical solutions, execution methods, and installation planning were discussed in detail, after which the work was carried out exactly as agreed."

"In particular, it was crucial that the agreed traffic closures of the bridge were respected. This was the most important parameter for the users of the bridge."
