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