The KC712 open-pit split type DTH drilling rig is a compact and efficient drilling machine designed for mining, quarrying, and rock blasting applications. It inherits the advantages of similar drilling equipment while optimizing structural design for better mobility, easier operation, and stable performance.
Unlike integrated drilling rigs, the KC712 does not include a built-in air compressor and is designed to work with an external air supply system, allowing flexible matching according to different project requirements.
The machine is equipped with a folded edge track frame, engineering-grade four-wheel track assembly, track leveling system, and inclined guide rail design, ensuring excellent stability and adaptability in complex terrains. Every structural optimization is designed to improve operational efficiency from a real working environment perspective.
Powered by a Yuchai YC4A100 diesel engine (70kW) (Yuchai), the KC712 delivers stable power output with low fuel consumption, making it a reliable solution for small-to-medium mining operations.
With a compact body and flexible drilling system, it is especially suitable for projects requiring easy transportation, quick deployment, and cost-efficient drilling performance.
