KG9 Down the hole Drill Rig Designed for Open Pit Mines and Quarries
The KG9 down the hold drill rig is designed for open pit mines and quarries for drilling holes with a diameter of Φ105－152mm in vertical, inclined, and horizontal orientation. This equipment is primarily applied for open-pit mines, stonework blast holes, and pre-splitting holes. Th drill rig is outfitted with an automatic unloading road system and a lubricating module drill rod and can be operated by a single worker. With hydraulic pilot operation, it is equipped with an anti-jamming system and optional drilling angle and depth indication functions to maximize drilling quality. The efficient dust-collecting system, spacious cab, high powered air-conditioner and quality stereo system provide comfortable and safe conditions for the operator for long work days and nights
