KRP-3-660/1140
Application

Road heading machine KRP-3-660/1140 is designed for driving of mine workings of the arched form with the cross-section of 8 m2 and the inclination of ±15º on saliferous rocks with cutting resistance up to 450 N/mm, as well as for extraction. These machines perform mined rock breaking, unloading it from the mine face and loading into vehicles installed behind the machine

Road heading machine KRP-3-660/1140 is a continuation of the PKS-8 combine series.
