The range of deep foundation machines involves four series: rotary drilling rigs (LB), piling- & drilling rigs (LRB), hanging and swing leaders (LRH) as well as duty cycle crawler cranes (HS).
A wide range of attachments means that the range of uses of duty cycle crawler cranes is almost unlimited. The main application areas besides material handling with grab and dragline are demolition, dynamic soil compaction as well as slurry wall grab and casing oscillator.
The Liebherr drilling rigs are designed for optimised drilling applications. All common drilling methods can be executed, e.g. Kelly drilling, continuous flight auger drilling, drilling with partial or full displacement tools, double rotary drilling and soil mixing.
The Liebherr piling and drilling rigs are conceived for different piling jobs with vibrator and hydraulic hammer as well as drilling jobs with double rotary head, continuous flight auger and Kelly drilling equipment. Liebherr also offers a range of high performance piling rigs which can be mounted directly on the boom and therefore operated at high outreach.
For special piling tasks that require long outreach Liebherr offers a wide range of basic machines with hanging or fixed leader. Depending on specific requirements the equipment use basic machines from the approved ranges of duty cycle crawler cranes (HS), crawler cranes (LR) or the rotary drilling rigs (LB).
