2018 CHINA RIG MACHINE GK-250 FACTORY SUPPLY

Main features
1. With oil pressure automatic feeding mechanism, improve drilling efficiency and reduce labor intensity.
2. The ball card holding mechanism can be used to realize the no-stop lever, easy to operate and safe and reliable.
3. The handle is centralized and easy to operate.
Equipped with hole bottom pressure gauge to indicate pressure, easy to grasp the situation in the hole.
4. The structure is compact, and the drill, water pump and power engine (diesel or motor) are assembled on the same base, which occupies a small area of the airport.
Light weight, strong decomposition, easy to move.
