Successful Experiences.
At MECTUNNEL, we believe that real-world cases speak louder than words. Below you will find summaries of successful experiences that showcase the type of work we do, the complexity of the challenges we face, and the value we bring to each project.
Extending the Life of Tools
Advanced wear protection for cutterhead tools
We have implemented custom wear protection treatments that significantly increase the lifespan of cutterhead tools. This not only extends tool usability but also allows for cost-effective repairs instead of full replacements. The result: reduced downtime, optimized performance, and better resource management.
Disassembly of False Tunnels
Fast and safe shaft segment removal
We have implemented custom wear protection treatments that significantly increase the lifespan of cutterhead tools. This not only extends tool usability but also allows for cost-effective repairs instead of full replacements. The result: reduced downtime, optimized performance, and better resource management.
Main Gear Breakdown Recovery
Emergency response to keep the tunnel moving
During one project, a major TBM main gear failure required urgent action. We designed and executed corrective measures that allowed the TBM to continue advancing until it reached a safe zone for full inspection and repairs—avoiding a total standstill and reducing potential financial losses.
Heavy Lifting Operations
Precision movement of TBM components
We have carried out heavy lifting operations involving major TBM components—and in some cases, entire TBMs. These operations were performed with high accuracy, using custom-designed methods to reduce the need for additional concrete structures and speed up the reinstallation process.
