Performance characteristics of YTR360C mining drilling machine

1. High torque makes the complete machine efficiently drill into rocks;

2. Rear-placed main winch with single drum and two reducers has long service life and provides more reasonable matching for the complete machine. Moreover, its single-layer winding of steel wire rope greatly improves the service life of steel wire rope;

3. Forward curved and decomposed transportation as well as flexible and convenient disassembly and assembly solve the problems of ultra-high and overweight during the transport process;

4. The mast adopts high strength, anti-bending and torsion resistant box beam, which can ensure the strength and stiffness of the mast;

5. Due to stable and reliable large triangular support of luffing mechanism, the drill ring can bear larger torque.

6. Centralized lubricating function can reduce labor intensity.

7. Due to the double-slewing reducers with high reserve capacity, the complete machine can work smoothly and can form high quality drilling holes;

8. With strong adaptive ability, the complete machine can be adapted to the construction in different regions and different strata.
