The medium-heavy class roadheader is designed for mechanization of breaking and loading of rock mass during preparation of arched, trapezoidal and rectangular tunnels with a raw cross section from 13 to 35 m2, and with inclination angle of ±18° for faces where coal and rock are mixed, with a breaking strength of rocks up to 110 MPa and abrasiveness up to 10 mg in mines hazardous with gas and/or dust.
Modular design of the cutting head gearbox, depending on the client's wishes, can be equipped with a gearbox with both transverse and longitudinal-axial arrangement of cutting bits.
Anchoring mechanization device reduces the time of one anchoring cycle by up to 50%, increasing work safety at same time.
Separate hydraulic drive of crawlers provides high manoeuvrability and can be used without fail in watered tunnels.
Loading stars of roadheader are not kinematically connected and work independently, which ensures high unit reliability.
Design of the scraper conveyor uses a reliable swivel section without use of flexible sheets..
