TUnIS Navigation TBMLaser

Navigation system for EPB, mixed shields and hard rock TBMs.

Based on a total station and a target unit installed within the TBM shield, it determines the current advance position.

Even for segment machines using a small or limited laser window, the machine position is continuously calculated during short-term interruptions. TUnIS Navigation TBMLaser features high reliability since it provides temporary navigation through the thrust cylinders.
