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 MT520 tunneling roadheader is a new concept of a construction roadheader in the 100 tons class, based on easily exchangeable modules, selectable to adapt the MT520 basic machine to a wide variety of applications.

An 8 meter cutting height module makes this machine highly suitable for large road tunnels. The full cutter motor power of 315 kW is available both on the transverse and on the inline type cutter head. An integrated dust extraction system caters for a healthy work environment of the tunneling team, and reduces maintenance downtime.
