· A roadheader is a machine intended for the excavation of underground headings, i.e. a machine which performs several functions within that process. A heading is an excavation characterised by considerable length in relation to its cross-section. These include various roadways, adits, crosscuts, drifts, inclines (sometimes shafts and staple

The Shaft Boring Roadheader (SBR) was developed for the mechanized sinking of blind shafts in soft to medium-hard rock with up to 120 MPa. For the efficient excavation of the rock, 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.
