The LB 55 drilling rig is the most powerful representative of the well-known LB series from Liebherr. Besides the common Kelly drilling other methods like continuous flight auger drilling, drilling with full displacement tools or double rotary drilling can be applied. The heavy-duty machine with an enormous torque of 550 kNm is very compact in design which guarantees a cost effective transportation and fast mobilisation on site. The rig is equipped with a powerful diesel engine which convinces through low consumption and reduced emissions. In combination with the board hydraulics and the opera...

    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.
    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.
    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.

    Automatic casing drive adapter
    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.
    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.
    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 Visualization
    Locking of the Kelly bar’s telescopic sections is made significantly easier due to the Kelly Visualization system.
    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.
