Herrenknecht developed the Downhole Boring Machine DHBM1750 for the fast and safe excavation of vertical holes with a depth of 10m and deeper in stable hard rock in a consecutive manner. The DHBM is designed for the mechanized excavation of highly accurate blind shafts with small diameter (1,765 mm) and for improved work safety conditions in narrow working environments. Its compact dimensions combined with the innovative crawler carrier system enables a highly flexible and precise maneuverability in confined spaces of underground mines. The crawler-based drilling rig and its trailer-based support unit are specially designed for underground use and enable autonomous positioning of the DHBM. The powerful full face cutting technology and its innovative mucking system ensure maximum performance.
Mit der Weiterentwicklung bestehender Technologien und profundem Engineering-Know-how erschließt sich Herrenknecht neue Geschäftsfelder.
