Eco silent mode

Eco silent mode

With the eco silent mode the engine speed can be reduced to a predefined, required level. With this feature a notable reduction in diesel consumption can be achieved without any impact on operational output. Noise emissions are thus also lowered.

Automatic engine stop

Automatic engine stop

The machine can optionally be equipped with an automatic engine stop control. Thanks to this feature it automatically switches off during longer work breaks after evaluating several machine parameters. This is fuel saving and environmentally friendly.

Fleet management and teleservice

Fleet management and teleservice

The data transmission and positioning system “LiDAT” provides important information on the operation of the machine. With these data the operation becomes more efficient. Various additional modules allow machine data reporting or access through service engineers via teleservice.

more
Casing oscillators

Casing oscillators

If required, Liebherr piling and rotary drilling rigs can be equipped with a number of casing oscillators which are operated via the machine’s on-board hydraulics. No external power pack is required which leads to significant cost savings.

Kelly drilling

Kelly drilling

Kelly drilling belongs to the most common dry rotary drilling methods. Soil and rock material is conveyed to the surface discontinuously with relatively short rotary drilling tools. more

Vibrating

Vibrating

Vibrating allows for installing and extracting elements using harmonious vibration. more

Continuous flight auger drilling

Continuous flight auger drilling

The loosened soil material is continuously conveyed to the surface using a continuous auger, the so-called continuous flight auger. more

Impact driving

Impact driving

Impact driving uses a hydraulic hammer for the installation of various types of pile. The hammer’s ram mass impacts on the pile. more

Full displacement drilling

Full displacement drilling

Full displacement drilling is a modification of continuous flight auger drilling. The drilling tool used is a smooth pipe with an auger-type starter piece. more

Double rotary drilling

Double rotary drilling

Double rotary drilling combines continuous flight auger drilling with a continuous casing. more
