TUnIS Navigation MTHydroLevel
Basic system upgraded with an electronic hydro level for straight tunnelling up to a maximum of 400 m
In order to neutralise the refractory influences acting on the laser as the tunnel length increases, the basic system TUnIS Navigation MTLaser is upgraded with an electronic hydro level for calculating the vertical machine position. Depending on the project configuration, this makes it possible to navigate straight drives with lengths of up to 400 m.
