VM series variable moment hydraulic vibratory hammers ensure maximum performance for minimum ground vibration and are perfectly suited to operate in urban areas or in areas sensitive to vibration(such as near to railways, vulnerable piping systems, under structures, and historic buildings.) Thanks to own resonance-free starting and stopping , our VM vibratory hammers can be suspended from a telescopic crane, a major advantage when you have to deal with a lack of working space or you have to execute your project speedily. In addition, the ability to adjust both the moment and frequency makes a VM vibrator the perfect hammer for different soil types and different profiles.

VARIABLE MOMENT TECHNOLOGY

This technology allows driving with adjustable amplitude thanks to the variation of the eccentric’s relative positions.

• Two stages damping system

Large elastomer provide excellent high frequency shock absorption and better protect crane boom. Small elastomer provide additional pulling force.

• German FAG high speed bearing

Bearings are most key components of vibro hammers. Via bearings the huge centrifugal force generated by the high-speed rotation of eccentric blocks is transmitted to piles. We adopts German FAG bearings, which have service life 5 times longer than ordinary bearings.
