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 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 MT720 has an extended field of operation for mechanized tunnelling in hard and abrasive rock formations. The robust stabilized telescopic cutter boom is ideal for optimum cutting power application, maintaining high productivity together with energy efficiency, which lowers overall operating costs.
The MT720 is available as PLC (Programmable Logical Controller).
