About Resonance-Free Vibrators

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 run down. The eccentric moment can also be switched on or off.

When the vibrator is started the eccentric moment is switched off and no vibrations are generated.

Once the vibrator has reached its operating frequency (2300 rpm) the eccentric moment is switched on and vibration immediately commences at this frequency.

Similarly, when stopping, the eccentric moment is switched off before the vibrator slows down.

This avoids transmitting resonances to the crane jib. In addition the amplitude can be infinitely adjusted to avoid exceeding the maximum permitted peak particle velocity

  • 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.
