Vibrator LV 20

With the LV 20 Liebherr provides a powerful high frequency vibrator for installing and extracting sheet piles, steel pipes and other piling elements. Thanks to the use of state-of-the-art components, the vibrator is particularly easy to maintain. It is installed on the LRB series of carrier machines, which deliver the necessary pull and push force through their rope crowd systems. For optimum piling performance and efficiency the hydraulic systems of the carrier machine and the vibrator are ideally matched.

Pre-Heating with Heat Exchanger

The LV 20 is fitted with an innovative heat exchanger, which prevents cold starts of the vibrator and so extends the service life. Pre-heating is a huge advantage especially on jobsites with low temperatures. The heat exchanger also works vice versa, namely as cooler. This in turn guards against overheating, which protects the vibrator.

Obstacle Recognition

An innovation for piling work in conjunction with the LV 20 is the obstacle recognition, which enables the timely recognition of obstacles in the soil.
