YC935 surface DTH drilling rig is based onYC930B surface DTH drilling rig with innovatively designed traveling part, guide, drill boom, and complete machine arrangement. It mainly has the following characteristics:

1, It is equipped with domestically well-known Yuchai YC4D80(Emission 2) diesel engine with strong power and reliable performance.

2, Thanks to wheel motor and traveling mechanism equipped with automatic leveling function, it is more adapted to rugged mountain road.

3, Hydraulic system is optimized to use hydraulic components from a famous manufacturer with low fault ratio.

4, Large angle amplitude variation mechanism can meet the requirement of different positions, which reduces assistant time and improves work efficiency.

5, It is equipped with roller type sliding plate to reduce wear of the guide rail.
