HC-42

Engineered for precision micropile drilling in space-constrained environments, the **Koken HC-42** represents a breakthrough in compact foundation drilling technology. Weighing just 125 kg, this horizontal drill rig balances portability with operational capability, making it ideal for dense urban construction sites, retrofit projects, and challenging access scenarios where traditional rigs cannot operate. The integrated hydraulic system delivers consistent force without excess weight, enabling rapid mobilization and setup while maintaining the structural integrity required for demanding foundation work. The **Koken HC-42 specifications** include a maximum drilling diameter of 300 mm and operational depth capacity of 20 meters, accommodating diverse soil conditions and stabilization requirements. Its advanced hydraulic drilling head generates the torque necessary for efficient penetration across varied geological formations, while the modular bit compatibility system adapts to project-specific demands. The intuitive control interface minimizes operational complexity, allowing operators to achieve precision placement and reduce installation errors—critical factors in micropile applications where accuracy directly impacts load-bearing performance. As a versatile **micropile-rig** solution, the HC-42 excels in underpinning, seismic retrofitting, and foundation reinforcement applications across commercial, industrial, and infrastructure sectors. Its compact footprint and self-contained design eliminate the need for extensive site preparation, reducing project timelines and enabling deployment in previously inaccessible locations. For contractors requiring reliable, efficient micropile drilling without site limitations, the Koken HC-42 delivers professional-grade performance in a transportable package.
