Sandvik’s MT series roadheaders with their geometrically optimized, transverse cutter heads offer superior cutting performance in a wide range of applications referring to different rock types and rock formations – from mineral / ore production of soft and little abrasive saline and industrial minerals to tunnel and underground cavern excavations in mechanical cutting challenging rock/rock mass conditions consisting of strong and significantly abrasive rock types like sandstone, schist and gneiss.

Sandvik MT520 Roadheader for Tunneling

MT521 Roadheader for tunneling

Sandvik MT521 roadheader, originally designed for cutting large cross sections in tunneling, is as efficient for use in production of soft industrial minerals like salt, potash and chalk. Its modular design offers more flexibility than standard roadheaders and works in most rock conditions up to ​100 MPa compressive strength.​​
