iCON® ZR Vibratory Drivers and Extractors

During start-up and shut-down when the vibrator frequency is in the 600-1200 vpm (10-20 Hz) range, conventional vibratory driver / extractors can create undesirable resonant frequency disturbances in the soil, older structures, and in the crane boom.

It is not possible to avoid this situation with conventional vibratory driver / extractors which have fixed eccentric moment.

iCON® Zero Resonance vibratory driver / extractors eliminate vibration in the damaging range by adjusting eccentric moment to zero during start-up and shut-down.

• Prior to start-up, the eccentric moment is set to zero.
• During start-up, vibrator frequency passes through 600-1200 vpm with zero eccentric moment and no disturbance in the soil, structures or crane line.
• After full operating frequency (2000-2300 vpm) is reached, eccentric moment is set to maximum for driving and extracting.
• Before shut-down, the eccentric moment is again set to zero.
• During shut-down, vibrator frequency again passes through 600-1200 vpm with zero eccentric moment and no disturbance in the soil, structures or crane line.
• The iCON ZR vibratory driver/ extractors are designed to never operate at a frequency range that could cause resonance vibration to the soil, structures or crane line.

Eccentric moment is controlled from the vibrator remote-control pendant. Shifting between zero and maximum eccentric moment occurs simply and quickly.
