Vibrator LV 20 Vibrator slim design

With the LV 20 Liebherr offers a powerful and innovative high-frequency vibrator for the installation or extraction of steel sheet piles, steel pipes or other piling elements. Through the use of state-of-the-art components the vibrator is particularly easy to maintain. It is leader mounted on the carrier machines of the LRB series. The rope crowd systems of these machines provide the necessary push and pull forces. The hydraulic systems of the carrier machine and the attachment are perfectly synchronized in order to provide especially high levels of production.
Max. centrifugal force 1,160 kN
Max. frequency 2,500 U/min

Features

Preheating to operating temperature

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

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.

Attachment recognition

Attachment recognition

The automatic attachment recognition also records performance figures of the respective attachment.

Purposeful energy focus

Purposeful energy focus

Thanks to the symmetrical suspension and low wear linear guiding of the vibrator, the swing movements run parallel to the axis which reduces loss of energy.

Large dimensioned main bearings

Large dimensioned main bearings

The ball bearings of the eccentrics’ shaft are largely dimensioned and so designed for a long service life.

Integrated control system

Integrated control system

The vibrator is completely integrated in the control system of the Liebherr carrier machines.

Continuous amplitude adjustment

Continuous amplitude adjustment

The patented external amplitude adjustment is robust in design, maintenance-free and allows for continuous regulation of the eccentrics.

Easy transport and maintenance

Easy transport and maintenance

Thanks to the short and lightweight design, the vibrator is extremely efficient as well as user-friendly in terms of transportation and maintenance.
