MT520

The MT520 tunneling roadheader is a new concept of a construction roadheader in the 100 tons class, based on easy exchangeable modules, selectable to adapt the MT 520 basic machine to a vast variety of applications.

An 8 meter cutting height module makes this machine highly suitable for large road tunnels.
