Vibratory driving

Vibratory driving

Vibratory driving is one of the most important methods used in specialized civil engineering. It is based on the principle of turning the soil into a quasi-liquid state by vibrating the pile section. The vibrations reduce the skin friction of the pile section and allow rapid driving progress. Vibrators can be leader-guided, free-riding or mounted on an excavator.

Vibrators and power packs are part of the typical set-up of a state-of-the-art system. The power pack is driven by a diesel engine and delivers the flow of oil for the vibrator via hydraulic pumps, thereby ensuring that the vibrator receives the constant supply of energy needed to vibrate the sheeting pilings into the ground.

MÜLLER vibrators H series. With fixed eccentric moment.

MÜLLER vibrators with constant amplitude – straightforward to use and robust. That is the foundation for good results in moderately difficult driving conditions. These vibrators are fitted with eccentrics that generate a fixed eccentric moment. With force-feed lubrication and oil cooling, this series is equipped for applications in extreme climatic conditions.


  • Soils with light to moderately difficult driving conditions
  • Driving and extracting tubular piles
  • Also in extreme climatic conditions

MÜLLER vibrators HHF series. Two in one.

Vibrator can be adapted quickly to different soil conditions by a simple system of adding or removing weights, allowing the eccentric moment to be varied. For example, if high frequency is required for work in loose sand, the additional weights can be removed simply on site to achieve high frequencies with the same centrifugal force.


  • Soils with moderate to heavy driving conditions
  • Suitable for heavy piles

MÜLLER vibrators HFV series. Variable and resonance-free.

The vibrators of this series ensure maximum performance for minimum ground vibration and are therefore ideal for applications in inner-city civil engineering works or in areas sensitive to vibration – guaranteed by the resonance-free starting and stopping. In addition, the amplitude can be infinitely varied during operations. The natural frequency of the soil can therefore be taken into account – driving proceeds effectively and at the same time with little vibration.


  • Inner-city civil engineering works
  • Areas sensitive to vibration
  • Chiefly sandy soils

Excavator mounted vibrators

Excavator-mounted vibrators. Compact all-rounders.

The compact, lightweight MÜLLER excavator-mounted vibrators can be attached to all common excavators. The power comes from the on-board hydraulics and the units are controlled by the excavator’s control levers. Various models (HFB, HFBV, HFBS) and useful accessories are available to suit the most diverse applications.


  • General driving, extracting and compacting work (MS-2 to -9 HFB)
  • Suitable for sheet piling and tubular piles with a modified clamp arrangement (MS-4 -6-7 and 9 HFB)
  • Installation of plastic and timber piles, lightweight sections, reinforcing cages (MS-1 HFB)
  • For vibration-sensitive projects or inner-city areas (MS-5 HFBV, MS-7 HFBV, MS-8 HFBV, MS-10 HFBV)
  • Jobs in heavy soils (MS-9 HFB, MS-17 HFB)
  • Pile sections can be picked up and set down directly with the clamp (MS-4 to -7 HFBS)

Leader-mounted vibrators

Leader-mounted vibrators. For tight spaces.

MÜLLER leader-mounted vibrators are the specialists for tight corners. They are mounted on leaders and offer contractors an adjustable moment plus resonance-free starting and stopping.


  • Driving and extracting sheet piles, tubular piles and H sections Foundation methods such as compacted gravel or sand columns
  • Driving and extracting single sheet piles with small dimensions Advantages
  • Compact design
  • Driving and extracting on cramped sites
  • Resonance-free starting and stopping
  • Minimum vibrations and emissions

Drill drives

Drill drives. Rounding off the range.

These robust, low-noise drilling units are quickly and easily attached to the stick of an excavator. Attachment to a leader or fitting in the clamp of a vibrator are available as options.


  • Pre-drilling to loosen and relieve the ground
  • Heavy soils

Power packs

Power packs. Power and intelligence.

Power packs are needed to drive hydraulic vibrators. Inside a soundproofed housing, a diesel engine drives the hydraulic pump that ensures the necessary flow of oil (required by the hydraulic motor) via hoses to the vibrator.

Every integral diesel engine is a low-noise, low-maintenance unit complying with the latest emissions regulations. Operations can be optimized and monitored via a programmable control connected via cable or a radio link. As an option, operating parameters and machine data can be called up remotely via a data modem.

Clamping devices

Clamping devices. A safe connection

MÜLLER clamping devices

Clamping devices connect the pile section, e. g., H sections or tubular piles, to the vibrator and transfer the vibrations. All units can be rotated through 90° for face working. Adapter plates are available to cope with different clamping arrangements. Clamps to fit over the interlocks of double piles and radial clamps for driving tubular piles are also available. Important for making the right choice: the clamping force of the clamping device must be at least 1.2 times the centrifugal force of the vibrator.


  • As single and double clamps for U/Z sections, H sections, and tubular piles
  • As special clamping devices for specific tasks, e. g., timber piles, concrete piles, and small-diameter tubular piles

Equipment selection guide – Which piece of equipment for which requirements?

Choosing the right machine is crucial for the economic and technical success of vibratory driving. In order to find the most suitable equipment, we offer our customers individual support that takes into account all relevant factors, i.e., the site conditions plus the geological and engineering requirements.


Selecting a suitable vibrator essentially depends on the size and weight of the pile section, the embedment depth, and the type of soil. Basically, the centrifugal force and the amplitude must be chosen in such a way that the skin friction and tip resistance between the pile section and the surrounding soil can be overcome.
