Roadheaders for tunneling

Sandvik Roadheader 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 or longitudinal 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 that cause harmful vibrations.

Powered electro-hydraulically, the MT series emits no fumes, 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. The roadheader family also includes separate multi-purpose hydraulic cutting heads for mounting on excavators.

Sandvik MT720 roadheader for tunneling

Sandvik MT720 is an electrically powered and crawler-mounted boom-type roadheader which is engineered to cut hard and abrasive rock beyond 120 MPa compressive strength at mechanized tunneling. This extremely powerful 100-ton-class roadheader has a powerful transversal cutter head mounted on an extremely robust telescopic boom.

Sandvik MT520 roadheader for tunneling

Sandvik MT520 PLC-controlled roadheader has been designed for use in tunneling, as well as salt, potash and chalk mining with a maximum profile up to 70 m². It has a modular design that offers more flexibility than standard roadheaders and works in most rock conditions up to ​100 MPa compressive strength.​​

Sandvik MR361 roadheader for mining

Sandvik MT361 roadheader is an electro-hydraulic part-face cutting machine designed for roadway development and for coal, rock, gypsum, potash and salt mining. The special attachments and wide array of options, such as an integrated swivel chain conveyor, coupled with high tramming speed for relocation, make it ideal for a variety of mining and tunneling applications. The powerful transversal cutter head of this roadheader is able to cut rock up to a compressive strength of 100 MPa (UCS).
