Product Description

Application scope:
This series of coal cutter is applicable to gently inclined long-wall coal face with a seam thickness of less than 1.5m and an included angle of less than 35° (when the inclined angle is greater than 15°, the machine should be equipped with antiskid device). The machine can realize mechanized mining of extra thin seam when it is used on the general coal face together with scraper conveyor and single hydraulic prop. The newly increased remote control can realize man-machine separation, easy operation and high safety.
Structural feature:
It consists of the tractive unit, power-driven unit, cutter, coal loader and such accessories as guide plate, dust cover and base plate.
