Vibrator LV 23 F

Vibrator slim design

The high-frequency vibrator LV 23 F is specially designed for all common methods of soil improvement. This includes the installation of vibro-replacement columns or vibrated cast-in-place piles. The flexible suspension of the exciter block in the yoke counterbalances the angular errors between the piling element and the leader, which is unavoidable in this application. This also minimises the loss of performance as well as the wear on all parts.

  • Eccentric moment - 0 - 23 kgm

  • Max. centrifugal force - 1,200 kN

  • Max. frequency - 2,400 U/min

Preheating to operating temperature
The gearbox oil is preheated and flows through the standing gearbox to the exciter block so offering improved lubrication. This minimizes wear and tear and extends the service life.
Continuous cooling
The cooling circuit is connected to the carrier machine and continues to cool even when the vibrator is not in use, so ensuring consistent cooling of the vibrator.
Large dimensioned main bearings
The bearings of the eccentrics’ shaft are largely dimensioned and so designed for a long service life.
Obstacle recognition
An improvement for slurry wall application is the obstacle recognition, which enables the timely detection of obstacles in the soil. This protects both the attachment and the basic machine.

Continuous amplitude adjustment
The patented external amplitude adjustment is robust in design, maintenance-free and allows for continuous regulation of the eccentrics.
Integrated control system
The vibrator is completely integrated in the control system of the Liebherr carrier machines.
