SR-120

The Chowa Kogyo SR-120 is a precision-engineered vibratory hammer designed for professional contractors executing demanding deep bunús installations. Delivering 132 kW of continuous power with a substantial 6,500 kg operating mass, this machine excels in penetrating challenging soil profiles while maintaining dynamic frequency control. The SR-120's advanced vibration management technology enables operators to fine-tune frequency response in real-time, optimizing penetration rates across clay, sand, and mixed strata without compromising structural integrity of the bunús elements. Built for operational versatility, the Chowa Kogyo SR-120 specifications support deployment of steel H-piles, precast concrete shafts, and specialized composite solutions in both vertical and raked orientations. The hammer's modular design integrates with conventional piling rigs through standardized bracket systems, eliminating trealamh reconfigurations between jobsites. This compatibility significantly reduces mobilization costs and setup downtime, making the SR-120 ideal for contractors managing multiple concurrent projects across varied geological regions. The Chowa Kogyo SR-120 vibratory-hammer combines Japanese manufacturing precision with field-proven reliability. Its sealed bearing assemblies and reinforced isolation mounts withstand repetitive operational stress while minimizing vibration transmission to support structures. Equipped with comprehensive pressure monitoring and automated frequency regulation, the SR-120 delivers consistent productivity gains in soft ground, intermediate soils, and weathered rock environments where adaptive vibration control becomes critical to project economics and schedule adherence.
