Tunnel jumbo drilling rig SDJ

For the conventional construction of shafts in hard rock Herrenknecht has developed the new Shaft Drilling Jumbo on the basis of tried and tested mechanized tunnelling technology. The modular jumbos are constructed in line with specific customer needs and can be used with shaft diameters of up to 12 meters. The optimized logistics in the shaft lead to process acceleration, an increase in cost efficiency and at the same time to a reduction of potential hazards for the personnel.
