Laser Tracker Industrial Measurement System LIS

Quality testing and safety are of great importance for tunnelling using segments.

Our quality control starts during the production of moulds for concrete and reinforced concrete segments, templates and segment test rings and ends after measurement of the manufactured segments. We use our portable semi-automatic LIS Laser Tracker Industrial Measurement System to check the basic geometry and parts built into moulds and segments.



The customer receives a target vs. actual comparison of the specified test criteria as well as comprehensive reports on compliance of project-specific tolerances. Direct comparison of results from moulds and segments belonging together allows design and production deviations in the sub-millimetre range to be detected.
