Boom-type roadheader MH621

Sandvik MH621 hard-rock miner is an electrically powered and crawler-mounted roadheader that is engineered to excavate roadways and galleries. This heavy-duty machine has a powerful transverse cutter head mounted on an extremely robust telescopic 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 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.
