About Resonance-Free Vibrators

What is a resonance free vibrator?

Resonance Free vibrators are the most advanced form of vibrator due to a mechanism which enables complete control over the output vibration. Through advanced eccentric moment control there is zero vibration during start up and shut down; the eccentric moment can also be switched on or off.

What Can a resonance free vibrator be used for? 

Resonance free Vibrators are often used where there is a need to minimise and localise potentially hazardous vibrations. Often used in urban environments, Resonance Free Vibrators are most suited to granular soil conditions such as gravel, sand and other particulate soils.

Key Specifications of resonance free vibrator

  • High frequency produces less ground vibration.
  • No harmful low frequency vibrations during starting and stopping.
  • Can be used closer to buildings than conventional vibrators.
  • Suitable for use with telescopic cranes
What are the benefits of a resonance free vibrator?

Because the eccentric moment is only engaged once the Resonance Free Vibrator reaches its operating frequency of 2300 rpm, harmful and noisy low frequency vibrations are virtually eliminated. Similarly, the eccentric motor is switched off before the vibrator slows down.

As well as providing a safer working environment, the removal of low frequency vibrations on start-up and shut down means there is no transmission of resonance to the crane jib.

In addition, the amplitude can be infinitely adjusted to avoid exceeding the maximum permitted peak particle velocity.
