Müller-vibrators with fixed eccentric moment (H series) The vibrators are fitted with eccentrics which generate a fixed eccentric moment of 25 or 50 kgm.

For continuous use or use in extreme climatic conditions, vibrators can be equipped with a forced lubrication system including oil cooling (H3 series). High-frequency Müller-vibrators with stepwise variable eccentric moment (HHF series)

The vibrators in the HHF series are suitable for a broad range of applications. The eccentric moment can be increased or reduced in steps by adding/removing additional weights, allowing one vibrator to achieve different amplitudes and frequencies.

 Eccentric moments of up to 190 kgm can be generated. High-frequency Müller-vibrators with variable eccentric moment (HFV series).

The classic pile driving setup includes a power pack and a vibratory hammer. The heart of any vibratory hammer is the exciter block, containing pairs of counter-rotating eccentrics running in heavy-duty special bearings.

Arranged at the top of the machine is a spring yoke, whose job is to absorb the vibrations caused by the exciter block before they can reach the carrier.

The power pack is driven by a diesel engine and supplies the oil flow to the vibrator via hydraulic pumps.

This ensures that the vibrator is supplied with energy to drive the piling into the soil.

Operating principle of a typical Müller vibrator

Series HF/H2:

  • HF/H2 hammers are suitable for driving and extracting in medium-driveability soils and are used as free-riding units or guided by leaders.
  • Müller vibrators, fixed static moment,
  • Constant amplitude – high power density

Series HHF "two in one":

  • HHF (two in one) units guarantee high power in medium to low driveability soils.
  • Müller vibrators "two in one", high-frequency, adjustable amplitude and frequency,
  • High performance – adapted amplitude
  • Normal frequency – large amplitude.

Series HFV:

  • ThyssenKrupp GfT Bautechnik uses specially developed high-frequency vibrators made in-house which run without resonance and guarantee environmentally friendly installation.
  • On the units with variable exciter blocks the eccentrics are phase shifted 180 degrees before the vibrator is switched on so that the eccentrics cancel each other out and the machine runs at zero amplitude.
  • Müller vibrators, variable high-frequency
  • Resonance-free starting and stopping – frequency and amplitude variable during operation
