High service availability

A global service network with experienced technicians and fast access to spare parts ensure high machine availability and a long product service life. more

Innovative crane control

Innovative crane control

The crane control system offers a multitude of programme and control options for various piling and drilling methods. Service and machine data is also provided on color displays. The operator thus benefits from a facilitated handling of the rig. Hence, quick working cycles are achieved.

Powerful drive technology

Powerful drive technology

The Liebherr-own and fuel efficient diesel engine generates the required power. In combination with the on-board hydraulics a sufficient amount of performance for various deep foundation works is provided. When using further attachments like casing oscillators, no additional power pack is needed. more

Designed for challenging jobs

Designed for challenging jobs

Piling and drilling requires a robust and torsion resistant leader. Moreover, thanks to its unique parallel kinematics a large operating area is achieved, thus guaranteeing precise and solid working. The telescopic undercarriage and the long crawlers offer a high level of stability.

Ground Pressure Visualization

Ground Pressure Visualization

The Ground Pressure Visualization calculates the current ground pressure of the machine in real time and compares it with the specified safety limits of the relevant jobsite.

Drilling Assistant

Drilling Assistant

During continuous flight auger drilling the concreting process is automated thanks to the Drilling Assistant.

Remote control

Remote control

The remote control simplifies the loading process for transportation as well as the assembly of the machine.

Kelly Visualization

Kelly Visualization

Locking of the Kelly bar’s telescopic sections is made significantly easier due to the Kelly Visualization system.

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.

Automatic casing drive adapter

Automatic casing drive adapter

The automatic casing drive adapter with remote control for locking and unlocking the casing pipe offers significant advantages in terms of safety as no personnel is exposed to the hazardous area. In addition faster production cycles can be achieved.

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.

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.

Applications

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

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

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

Down-the-hole drilling

Down-the-hole drilling

For down-the-hole drilling a hammer is mounted on the lower end of a drill rod. The hammer is activated by adding compressed air. 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

Vibrating

Vibrating

Vibrating allows for installing and extracting elements using harmonious vibration.
