Integrated Surface DTH Drilling Rig, KT9C

Down-the-hole drill rig for open-pit mining

Integrated Surface DTH Drilling Rig, KT9C

This machine is tailored with a high-efficiency and energy-saving drilling rig for small and medium-sized open-pit mines, quarries and infrastructure construction sites. The machine’s screw air compressor and hydraulic pump are powered by an engine with a two-terminal output, which enables the compressor to function in full speed and drill rocks efficiently. The engine comes from Cummins which meets China Stage III emission standards. The rig is equipped with an oscillator that brings a larger pitch and guarantees excellent stability in different terrain. The mining machine is also equipped with a durable sebific duct and an advanced dust collector that is aimed to reduce dust pollutants. All components are in a clear layout, allowing for an easy upkeep or repair.
