The Shaft Boring Roadheader (SBR) was developed for the mechanized sinking of blind shafts in soft to medium-hard rock. Unlike the Shaft Boring Machine (SBM) with a hard rock cutting wheel installed, the SBR has been equipped with a roadheader boom and a rotating cutting drum. This allows the creation of variable shaft diameters between 7 and 12 meters. Based on the proven technology of Herrenknecht Vertical Shaft Sinking Machines (VSM), the new development offers a higher level of work safety compared to conventional shaft sinking with simultaneously higher advance rates.
