This new having no analogues light duty roadheader with the performance exceeding
the existing machines of the same class is designed to mechanize breaking and
loading the mined rock while driving mine workings of rounded, arched, trapezoidal
and rectangular forms of section in coal and mixed faces (50% of coal and 50 % of
rock) with single-axis compressive strength of up to 80 MPa and abrasivity not more
than 15 mgs with an inclined gradients ±12° in mines hazardous on gas (methane) and
coal dust. Working rock section driven by the machine from one placing is 8..17m2.

Features |
- Robust cutting boom powered by a 55 or 75 kW air cooled electric motor
- Cutting head with efficient pick face flushing facility
- Telescopic action to allow cutting head to be sumped in with the machine
stationary and therefore independent of floor conditions
- Center scraper chain conveyer built for abrasive applications
- Crawler tracks which are independently operated to give maximum machine
maneuverability for working on steep gradients and poor floor conditions
- Real floor sprag jack to increase machine stability in adverse cutting
conditions
- Loading apron performs as a front support
- Scraper conveyor and stage loader enable to use the machine with various type
of excavated material handling
