Roadheaders for hardrock

Sandvik MH621 Roadheader for hardrock

Our electrically powered, crawler-mounted Sandvik hard-rock miners are heavy-duty roadheaders designed to excavate roadways and galleries through rock with compressive strengths beyond 100 MPa. Sandvik roadheaders offer superior productivity without damaging the rock mass surrounding the tunnel.

Sandvik roadheaders for hardrock are equipped with powerful transverse cutter heads mounted on a robust hydraulically stabilized telescopic cutter boom. This enables these machines to achieve high advance rates and to sump into the face without moving the tracks. Flameproof (FLP) versions can be delivered according to the specific requirements of the operation.
