Technical Specifications: KT15C
Power: 298 kW /2200r/min
Drilling Diameter: 140-190 mm
Drilling Depth: 36 m
The KT15C integrated down the hole drill rig for open use can drilling vertical, inclined and horizontal holes, mainly used for open-pit mine,stonework blast holes and pre-splitting holes. It is driven by the Cummins China stage III diesel engine and the two-terminal output can drive the screw compression system and hydraulic transmission system.
The drill rig is equipped with high strength aluminum alloy propulsion beam, variable hydraulic system， automatic rod handling system, drill pipe floating joint module,drill pipe lubrication module, drill pipe sticking prevention system, hydraulic dry dust collection system, air conditioning cab, optional drilling angle and depth indication function, etc. The dill rig is characterized by excellent integrity, high automation, efficient drilling, environment-friendliness, energy conservation, simple operation, flexibility and travelling safety, etc.
