Sandvik MT520 tunneling roadheader is based on a modular machine concept - a construction roadheader in the 100 ton class with easily exchangeable modules, selectable for adapting the MT520 machine to a wide variety of applications. Its modular design offers more flexibility than standard roadheaders and works in rock conditions up to 100 MPa compressive strength. The full cutter motor power of 315 kW is available for both the cutter head types – the transverse one and the longitudinal or inline one.
Sandvik's MT series of roadheaders offers high cutting performance in a wide range of rock formations. Equipped with geometrically optimized transverse or longitudinal cutter heads, these flexible machines are used for a wide range of applications including rehabilitation of existing tunnels and excavation of underground caverns. Sandvik roadheaders let you focus on the essential: Easily breaking through from one side to the other. They are designed to excavate continuously without using explosives, minimizing environmental damage and adding safety to your operations.
Powered electro-hydraulically, the MT series emits no fumes, makeing them suitable for underground construction projects also in urban areas. Sandvik roadheaders are equipped with advanced profile control, automatic sequence control systems and online data processing possibilities.
