Deep FoundationMachinesPiling and drilling rigsLRB seriesLRB 355.1

The combined piling and drilling rig LRB 355.1 can be used for a great number of different applications including drilling with Kelly equipment, double rotary head, full displacement tool and continuous flight auger as well as soil mixing and piling jobs with vibrator and hydraulic hammer. The multifunctional machine is designed for a reliable continuous operation. With the powerful as well as fuel and emission efficient V12 diesel engine great output is realised. Large vibrators and drilling equipment are operated by the machine’s own hydraulic system. Thanks to the parallel kinematics the ...

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.
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.
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.
Innovative crane control
The crane control system offers a multitude of programme and control options for various piling and 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.
High service availability
A global service network with experienced technicians and fast access to spare parts ensure high machine availability and a long product service life.

Casing oscillators

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.
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.
Vibrating
Vibrating allows for installing and extracting elements using harmonious vibration.
Continuous flight auger drilling
The loosened soil material is continuously conveyed to the surface using a continuous auger, the so-called continuous flight auger.
Impact driving
Impact driving uses a hydraulic hammer for the installation of various types of pile. The hammer’s ram mass impacts on the pile.
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.
