Our resonance free variable moment vibratory hammers (VM series) stand out for their high frequency and resonance resistance features, offering a maximum centrifugal force range of 1030kN to 4350kN. Customization is available to meet your specific requirements. The high frequency enables our hammers to penetrate the ground effectively. Resonance resistance ensures safer piling. VM series hammers can be installed easily and equipped with clamps and beams, providing stable and efficient piling solutions.
