HFV and mHFV Series – High Frequency Vibrodrivers
PTC's high frequency vibrator with hydraulically controlled variable eccentricity was introduced in 1992, and has the ability to start up and stop without any vibration. The HFV vibrators exceed international norms for limiting noise and vibration emissions, and enabling operation in sensitive areas or close to delicate equipment.
Exclusive variable amplitude vibrators advantages include:
- Reduction of noise level
- Reduction of vibrations transmitted towards the ground
- Resonance free start up and stop down
- Adapting the amplitude to the ground
