KT12 Integrated Down the hole Drill Rig


The KT12 integrated down the hole drill rig is driven by a Cummins China stage III diesel engine and the two-terminal output can drive the screw compression system and hydraulic transmission system. It is capable of drilling φ115-152mm vertical, inclined, and horizontal holes. The rig is most commonly used for open-pit mines, stonework blast holes, and pre-splitting holes. The drill rig is equipped with an automatic rod handling system and lubricating module of the drilling rod, meaning only one operator is needed and fewer mining operations are required. The main control action is integrated into one handle for greater user-friendliness. It is equipped with an anti-jamming system and optional drilling angle and depth indication are available, thus simplifying drilling and improving the drilling quality. The efficient dust-collecting system, spacious cab, high-powere dair-conditioner and quality stereo system provide comfortable conditions for operators.
