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.​

Advantages

  • Designed for the economical excavation of rock exceeding 100 MPa uniaxial compressive strength to minimize operating costs
