Roadheaders for tunneling

Sandvik's MT series of roadheaders offers the best cutting performance in a wide range of rock formations. Equipped with geometrically optimized transverse cutter heads, these flexible machines can be used for a wide range of applications. They can also be used for rehabilitation of existing tunnels, and excavation of underground caverns.

Sandvik roadheaders let you focus on the essential: breaking through to the other side with minimum fuss. They are designed to excavate continuously without using explosives causing harmful vibrations.

Powered electro-hydraulically, the MT series emits no fumes and no vibrations, which makes them suitable for underground construction projects in urban areas. Sandvik roadheaders are equipped with advanced profile control, automatic sequence control systems and online data processing possibilities.

Sandvik MT720 is an electrically powered and crawler-mounted boom-type roadheader which is engineered to cut hard and abrasive rock mass of up to 140 MPa unconfined compressive strength (UCS), and in extreme cases of even up to 180 MPa in tunneling applications. This extremely powerful 100+ tons-class roadheader has a powerful transversal cutter head mounted on an extremely robust telescopic boom.

Sandvik MT520 Roadheader for Tunneling

Sandvik MT520 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.​​
