It’s traveling, propulsion, rotation, and angle adjustments are based on hydraulic drive, thereby proving its powerfulness. The high air-pressure screw nose and high air-pressure DTH hammer contribute to efficient drilling. It is equipped with a dry hydraulic dust collector. thus reducing pollution. The hydraulic mechanical arm and drilling rod warehouse are used to dismantle the drilling rod and the floating joint to protect the thread of the drilling rod; one operator can dismantle the drilling rod. The air-conditioned cab provides comfortable space and the anti-jamming valve with automatic control reduces the possibility of sticking. And what is more, the drill rig is characterized by excellent integrity, high automation, efficient drilling environment-friendliness. energy conservation, simple operation, flexibility and traveling safety, etc.
