Integrated Surface DTH Drilling Rig, KT9D
Down-the-hole drill rig for open-pit mining
This machine is made with drilling rig that works in a high-efficiency and energy-saving way, which is, no doubt, a good choice for owners’ of small and medium-sized open-pit mines, quarries and infrastructure construction sites. The machine’s screw air compressor and hydraulic pump are driven by an engine with a two-terminal output, which enables the machine to drill rocks efficiently. The engine is a cut-end product 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.
