Designed for supporting and controlling the roof in mined area of face while operating flat seams of 0.95-4.1 m thickness.
- optimized construction to operate in thin and medium seams with medium-weight roofs according to GOST 31561;
- effective operation in conditions of unstable direct roof using the high retaining console effort with transmitting an effort from the hydraulic prop (patented);
- long-lifetime power hydraulic system;
- effective and reliable European-made control system of different types: pilot control, multi-hose control, electric-hydraulic control.
