Tunnelling and mining The Sandvik MR620 is an electrically powered and crawler-mounted roadheader that is engineered to excavate roadways and galleries. This heavy-duty machine has a powerful transversal cutter head mounted on an extremely robust telescopic boom. It is designed to excavate rock with high compressive strengths. The MR620 is available as PLC (Programmable Logical Controlled) or hydraulically controlled machine. According to country regulations the machines can be delivered with FLP (flameproof) certifications from various international approval authorities. Designed for economical excavation of rock exceeding 120 MPa uniaxial compressive strength to minimize operating costs. Hydraulically stabilized telescopic cutter boom offers optimum cutting power. Spraying systems efficiently suppress dust and cool cutting tools.
