The Tünkers hydraulic vibration drivers are based on the principle of self-synchronisation and produce flawless directional vibrations.
The vibrators are equipped with shafts with eccentrically mounted masses running in opposing directions and are driven by hydraulic motors that transmit the torque directly to the excenter shafts.
Self-synchronisation is produced by the centrifugal force and the constructive concept in one fixed and one freely movable vibration body. Since there are no gears and transmissions in this design, oil lubrication is not required. No high operating temperatures are generated and the noise emission is low. There are no failures because of transmission damage and no reduction of the lifespan of the roller bearings.
Practical experiences have proven these design features to be the most suitable concept for vibration machines.

Special Features
- Self-Synchronization (without gears)
- Low noise, easy to maintain and dependable
- Powerful and robust through high output. Output Factor 3 kW per 1 t centrifugal force
- The compact design with short length and low center of gravity prevents oscillating motions and overturning at the rammed body.
- Low dynamic dead weight of the vibrator
- High degree of efficiency through direct drive
- Suited for under-water and low temperature applications
- Long life span of the roller bearings
- High frequency version 0-2300 min-1
- Operation method based on guide and mounting rail
- Tilted and horizontal ramming
- DUAL-System, switch-over between frequencies at same centrifugal forces. Optimal adjustment to the soil structure and the rammed body
- The guide and mounting rail can be longitudinally or laterally fixed to the vibrator absolutely vibration-free.
- Vibration dampers generate high extracting forces and absolute absorbtion of vibrations by means of progressive cushion characteristics of the pressurised rubber spring. High operational safety while extracting, no kickback of the outrigger.
New Systems for Ramming Technology - Two in One
Hydraulic Vibration Driver HVB 100 / 200 Vario
Main Characteristics
- The vibrator unit can by applied as a standard machine with 0-1600 RPM or as a high- frequency machine with 0-2300 RPM with stepless shifting of the unbalance load and RPM.
- Since the adjustable unbalances are not activated until the desired RPM are reached, no damaging resonance vibrations occur when accelerating or decelarating the vibration driver.
- Within the RPM range, the centrifugal force can be steplessly changed. Thus, an optimal adjustment of the centrifugal force to the soil conditions and the rammed body is possible. This is advantageous when ramming lighter profile, as after stabilization of the body, the centrifugal force output can be increased steplessly as required.
- Universal application possibilities as standard or high-frequency vibration driver
- Resonance-free operating method at startup and coast-down
- Forced synchronisation of the unbalance shafts through synchronous belt drives
- Optimal adjustment of the centrifugal force output to the soil conditions rammed body
- Precise manipulation, monitoring and control by means of a PLC
- No gear or transmissions
- No oil lubrication but grease lubrication
- Vompact design – low total center of gravity
- Low dead weight allows for use of cranes with low lifting power
- Low-maintenance
- No over-heating due to oil or bearings
- Direct drive of the unbalance shafts, no gears
- Vibration damper – pre-compressed rubber spring – no heavy loading
- High degree of efficiency through direct drive
