FR 250

FR 250 roadheader is a machine designed to meet customers’ most demanding requirements. The use of advanced technologies allows efficient operation in different geological and mining conditions.

The machine is equipped with modern data transmission systems, radio remote control and sensor system providing accurate diagnosis of work and operating personnel safety. Overload-proof, modern and simple hydraulic system provides trouble-free operation and easy control of the roadheader.

The FR 250 is designed to make roadways up to 4.7 m high, in rocks having compressive strength up to 110 MPa. The machine is designed to operate in underground mines, in non-methane and methane conditions, with a longitudinal inclination up to ±18° and transverse inclination up to 8°, in ambient temperature of maximum +40°C.
