CJ-330E

The **Chowa Kogyo CJ-330E** is a professional-grade vibratory hammer designed for demanding foundation installation projects where conventional equipment reaches its operational limits. At 18 metric tons, this heavy-duty attachment combines vibration technology with integrated jetting capabilities to accelerate pile penetration through challenging soil conditions. The synergistic approach of simultaneous vibration and controlled pressure jetting significantly reduces soil resistance, enabling faster cycle times while minimizing structural strain on both the pile and mounting equipment. **Chowa Kogyo CJ-330E specifications** deliver impressive operational parameters suited for complex geological scenarios. The unit generates 330 kN of centrifugal force across a precisely controlled frequency range of 30–50 Hz, allowing operators to fine-tune performance for specific soil profiles and geological layers. The integrated jetting system operates at peak pressures of 10 MPa, creating effective soil liquefaction around pile perimeters and facilitating smoother, deeper penetration in dense and stratified formations commonly encountered in marine foundation work and complex ground improvement projects. The **Chowa Kogyo CJ-330E** proves indispensable for specialized applications including offshore pile driving, deep foundation engineering in saturated soils, and large-diameter installation work where precision and reliability are paramount. Its dual-action mechanism—combining vibratory acceleration with hydraulic soil liquefaction—establishes a new standard for performance in geotechnical projects that demand both power and controlled execution across variable substrate compositions.
