RPD-20L

The Koken RPD-20L is a precision micropile-rig engineered for geotechnical professionals requiring compact, high-performance drilling solutions in confined spaces. Powered by an efficient 18kW hydraulic system delivering 20 tons of thrust, this Japanese-built unit excels at anchor bolting, rock stabilization, and slope reinforcement—applications where site access and equipment footprint are critical constraints. At just 410kg, the Koken RPD-20L provides the power and precision of much larger systems while maintaining exceptional portability for challenging job sites. Koken RPD-20L specifications are optimized for versatility across diverse geotechnical challenges. The adjustable drilling angle mechanism and universal bit compatibility enable operators to adapt drilling approaches for variable soil and rock conditions without equipment changes. This flexibility—combined with the unit's lightweight, portable design—makes the micropile-rig equally effective for emergency underpinning, slope stabilization, and foundation reinforcement projects in mountainous or restricted-access locations. The Koken RPD-20L micropile-rig delivers professional-grade performance for specialized foundation work, emergency response drilling, and geotechnical stabilization in environments where conventional equipment cannot operate. Engineers and contractors rely on this system's proven reliability to provide precise, cost-effective deep foundation solutions while maintaining operational efficiency in space-constrained environments.
