At the tunnel face, accuracy has traditionally depended on experience, visibility and intermittent feedback. TUnIS Navigation Excavator changes this by bringing continuous positional awareness and real-time visualisation directly into the excavation process.
Operators rarely receive uninterrupted information about the actual excavation during work. The result: frequent rework, uneven profiles and higher shotcrete consumption – combined with the fact that personnel often operate close to the face. TUnIS Navigation Excavator was developed to improve profiling accuracy while reducing manual exposure underground.
How the system keeps excavation on track
A combination of total station, prism tracking and gyroscope technology continuously updates the excavator’s position in the tunnel. Robust, IP65-compliant hardware with inclinometers along the boom segments captures all relevant movements, while radio transmission ensures seamless communication with the TUnIS computer.
The system fits a wide range of excavator types and can be extended with TUnIS Navigation Office for data analysis and remote monitoring from the construction office.
A smooth and safe process
Continuous comparison of the actual profile and the design profile supports optimised machine operation in 2D and 3D. This enables faster profiling, fewer corrections and lower shotcrete consumption.
Machine operation becomes more consistent, safety improves thanks to reduced manual work at the face, and continuous monitoring allows quicker, more targeted intervention.
In short: TUnIS Navigation Excavator brings clarity, control and safer workflows to Conventional Tunnelling.
