KTW-200

The KTW-200 roadheader is designed for driving galleries of cross-sectional area amounting to 35.5 m2. It is capable of mining rocks whose compressive strength amounts to 110 MPa. The roadheader can be operated in coal mines or used for tunneling.

Bit blocks with injector air suction are used in the KTW-200; they ensure proper spark suppression and reduction in dustiness.

Water batteries mounted on the arm and cutting heads with built in sector distributor produce water spray curtain.

Total spraying system capacity amounts to ca. 65 l/min.

The roadheader is equipped with electrical motors manufactured by the DAMEL factory, certified in conformity with IEC-60079 standards and electrohydraulic distributors manufactured by the Bosch – Retrox companies in corformity with by ATEX certificates.
