KT7C Integrated Down the hole Drill Rig for Open Pit Mines and Quarries

The KT7C high air-pressure down the hole drill rig for open use is an advanced drilling device integrating a down the hole drilling system and screw air compression system. Featuring a compact structure typical in our products, the rig has excellent integrity and mobility. It is equipped with a single-stage high air-pressure screw hose and the flow is 13 cubic meters per minute and pressure is 1.7MPa, thereby providing high-valued parameters. The drill rig provides strong power for the high air-pressure down the hole hammer and the drilling speed is higher than that of medium-air pressure drill rigs by 20%-50%. It is characterized by energy efficiency, safety, environmental-friendliness, flexibility, and simple operation. Equipped with a Yuchai China stage III engine, the drill rig meets national standards for emissions and environmental impact.

Feature
The drilling rig is equipped with a screw air compressor and adopts high air pressure pneumatic impact. The drilling rig operates with high efficiency, and low energy consumption. The drilling rig is equipped with a hydraulic dry integrator to collect dust and reduces the pollution of the environment. The drilling rig is equipped with a hydraulic manipulator, the drill pipe warehouse which disassemble the drill pipe and the floating joint which protects the thread of the drill pipe.
