In microtunneling a tunnel laser mounted in the shaft acts as the base of the guidance system. Our Mini Video Target serves as the target unit, for smaller diameters our Micro Video Target is used.
The completely encapsulated Video Targets (IP68) meet the requirements for the tough environment of a microtunneling machine.
Horizontal and vertical deviation relative to the alignment, roll, pitch and chainage, are continuously displayed on the operator’s screen.
