Basic machine and leader with all hydraulic hoses connected can be transported in one piece. The minimized assembly work allows for quick and easy transportation of the machine between jobsites. Hence, time and money is saved even before operation starts.
A global service network with experienced technicians and fast access to spare parts ensure high machine availability and a long product service life. more
The crane control system offers a multitude of programme and control options for various 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.
The hydraulic BAT rotary drive designed by Liebherr delivers the required torque for a wide range of drilling applications. The automated torque adjustment and the continuous speed optimization react flexibly to changing soil conditions – this guarantees an optimum crowd force. more
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.
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

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.
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.
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.
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
With the PDE process data recording system machine data is recorded during the working process. With PDR these data can be managed, displayed tabularly or graphically, and analyzed. In combination with the telematics system LiDAT these reports can be easily generated from the office. more
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.
Increase of drilling diameter and depth
When producing piles with very large drill diameter or depth the rig can be fitted with an optional equipment package, which includes a longer leader, additional ballast weight and extended drilling axles.
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
The loosened soil material is continuously conveyed to the surface using a continuous auger, the so-called continuous flight auger. more
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 combines continuous flight auger drilling with a continuous casing. more
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
