With the LB 45.1, Liebherr presents its successor to the proven drilling rig LB 36-410. Its torque is 450 kNm – a 10 % increase in comparison to its predecessor. Various methods such as Kelly drilling, continuous flight auger drilling, partial and full displacement drilling or double rotary drilling can be applied. Despite of its large machine class the upper carriage is compact and designed for small working radii. This allows for working at jobsites with limited space.

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.
Rotary drive with selective Kelly shock absorber
The latest version of the rotary drive has a newly developed Kelly shock absorber, which allows the damping strength to be adapted depending on the respective weight of the Kelly bar.
Modular design
Both the counterweight and the leader are modularly constructed. This enables quick and easy assembly and flexible application.
Increased drilling depth
The maximum drilling depth for Kelly drilling with 5-fold Kelly bar has been increased to 100 m and so significantly improved.
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.

Low-head leader system
At jobsite conditions with limited heights, such as under bridges or below power lines, the rig can be equipped with a shortened “low-head” leader.
MyJobsite
One single tool for the collection, documentation and analysis of all process, machine, construction site and position data.
Recording of working processes (PDE)
With the PDE process data recording system machine data is recorded during the working process.
LIPOS positioning system
Accurate positioning and precise execution of piling or drilling processes.
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.
Remote control
The remote control simplifies the loading process for transportation as well as the assembly of the machine.
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.
Continuous flight auger drilling
The loosened soil material is continuously conveyed to the surface using a continuous auger, the so-called continuous flight auger.
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.
Double rotary drilling
Double rotary drilling combines continuous flight auger drilling with a continuous casing.
Wet soil mixing
For wet mixing a self-hardening suspension is introduced into the ground.
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.
