The unit is required to drill a 5-km long tunnel with a diameter of approx. 6, 5 m.
The drill is sitting at the head of the first wagon. And right behind is the m-tec SMP with special silo, which supplies material for the filling of ground elements of the tunnel with the sprayed concrete robot. The charge is enough for one drilling cycle.
On the second wagon, which is driving off the tunnel during the drilling, in order to transport drilling material and provide new material e.g. as for the SMP, sits a G140 with another silo. During the cycle breaks thus fills the special silo of the SMP.
