The HFGA47S Integrated down the hole drill rig for open use is a new drilling device developed by Hanfa Group after years of development and production of down the hole drill rig to meet the needs of large open-pit mines. Its travelling, 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 the 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 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. enerdy conservation, simple operation, flexibility and travelling safety, etc.
