dh R75

Roadheading machine (weight class 70 t) with optional integrated drilling and bolting device

Due to a machine height of 2,500 mm, a total weight of 70 t and installed cutting power of 200 kW the R75 roadheader is ideally suited for the challenges posed by development drivage work under severe operating conditions. It allows cutting of roadway profiles up to 31 m². The optional integrated drilling and bolting system makes for quick installation of rock bolts and additionally offers drilling of boreholes in direction of the face for exploration or pre-lining in case of difficult roof conditions.
