LB 20.1 Drilling rig (LB series)

The LB 20.1 is Liebherr’s smallest drilling rig. The range of drilling applications include Kelly drilling, continuous flight auger drilling (CFA) and double rotary drilling. The compact design guarantees the simple, fast and thus economical transport as well as a quick set-up at the job-site. The LB 20.1 can be transported on a standard low-loader truck with its folded leader including the rotary drive. The rig can be optionally equipped with a shortened leader system which is perfect for construction sites with height limitations.
Operating weight 52.8 t
Max. torque 200 kNm
Kelly drilling, max. drilling depth 34.5 m
Kelly drilling, max. drilling diameter 1,500 mm

High performance

High performance

Strong winches enable highest performance even under the most difficult conditions. Furthermore, the noise emission is considerably reduced thanks to their elastic mounting.

Modular design

Modular design

Both the counterweight and the leader are modularly constructed. This enables quick and easy assembly and flexible application. more

Various drilling axes

Various drilling axes

The leader top is designed for different drilling axes and is therefore suitable for all applications.

Easy transportation and quick set-up

Easy transportation and quick set-up

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.

Comfort

Comfort

This includes a modern air-conditioning system with improved airflow, an optimized field of vision and increased noise protection, as well as an orthopaedic operator’s seat with integrated heating and cooling.

Innovative crane control

Innovative crane control

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. more

Designed for challenging jobs

Designed for challenging jobs

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.

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.

Drilling Assistant

Drilling Assistant

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

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.

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
