RPD-220

The Koken RPD-220 is a versatile drilling-rig platform engineered to meet the demands of high-capacity rock excavation across diverse geological environments. Featuring the precision-engineered KD-1800 drill head, this model delivers consistent penetration performance in hard rock formations while maintaining operational control in complex subsurface conditions. The Koken RPD-220 specifications highlight a powerful 90kW engine paired with an advanced hydraulic architecture that generates exceptional torque for sustained drilling operations, making it a dependable solution for contractors managing extensive boreholes and foundation engineering projects. Designed for maximum versatility, the Koken RPD-220 offers drilling depths reaching 60 meters with bore diameters up to 1,200 mm, accommodating both exploration and production-scale requirements. The rig's integrated monitoring system delivers real-time operational feedback, enabling precise depth control and early detection of formation changes. Its hydraulic efficiency translates to lower fuel consumption relative to output, reducing per-meter drilling costs while the modular footprint supports rapid relocation between job sites and confined work areas. The Koken RPD-220 excels in infrastructure applications including foundation drilling for bridge and tunnel projects, geothermal resource assessment, and civil engineering investigations where reliable deep-hole capacity is essential. Its combination of drilling range, power density, and automated feedback systems positions it as a preferred choice for operators prioritizing both production efficiency and safety compliance on large-scale ground development initiatives.
