MH621 Roadheader for hardrock

Sandvik MH621 hard-rock miner is an electrically powered and crawler-mounted roadheader that is engineered to excavate roadways and galleries in strong rock formations. This heavy-duty machine has a powerful transverse cutter head mounted on an extremely robust telescopic cutter boom. It is designed to excavate rock with high compressive strengths.

MH621 is available as a PLC (programmable logical controller) controlled machine. Country-specific FLP certifications by various international approval authorities are possible.​


  • Improved safety features ensure safe underground working conditions and less operational hazards.
  • Heavy duty, robust machine design and ICUTROC cutting technology for hard rock application increase machine availability and reduce machine service costs.
  • Different cutter heads for a wide range of rock conditions and applications serve for high versatility in machine operation.
  • Optional machine guidance system significantly improves profile accuracy and decreases tunneling costs.
  • Various digitalization options like Cutronic (automated cutting cycle), which enables semi-autonomous machine operation, optimize customer value.
