In June this year, Liebherr presented its new piling and drilling rig, type LRB 16, suitable for the diverse requirements of deep foundation work. It features a compact design as well as a range of available assistance systems, which ease the work on the jobsite. With a longer leader, the piling and drilling rig is also available as a LRB 18.

The LRB 16 gets its name from the sledge’s travel distance, which is approximately 16 metres. Special emphasis is on the compact design and an operating weight of barely 48t, which results in low ground pressure. The robust undercarriage offers excellent stability, which can be further increased with the optional rear supports.

Economic fuel consumption is more than just a theory with the LRB 16. Innovative hydraulic concepts play a decisive role and, despite reduced engine power, the machines achieve high performance but at the same time keep fuel consumption low. The new piling and drilling rig is installed with a Liebherr diesel engine. It has a mere 390 kW/523 hp and meets current emission regulations. In comparison to earlier models, the LRB 16 has a reduced engine speed of about 1,700 rpm.

The parallel kinematics, which have been installed in many piling and drilling rigs from Liebherr, have a large working area and enable the leader to be folded back. The rigid leader of approximately 12.5 metres absorbs high torque and is fitted with a rope crowd system for high pull forces of up to 200 kN. Furthermore, the quick connection system allows for the rapid fitting or exchange of working tools.

The LRB 16 can be easily transported in one piece, including the mounted counterweight, and has a transport weight of only 43.5 t. This ensures quick set-up on site as well as flexibility in transferring the machine between different jobsites. As an option, the complete loading and set-up processes can be carried out via remote control, which means only one person is required.

High operator comfort

Particular attention was paid to the cabin concept of the LRB 16, especially to the improvement of operator comfort. This was achieved, amongst other things, through a modern air conditioning system, an optimized view from the cabin as well as an orthopaedic operator’s seat with automatic adjustment. All switches, joysticks and pedals are ergonomically positioned. Furthermore, a roof railing and rear-view and side cameras enhance safety.

One of the most frequent applications for the LRB 16 is the installation of slurry walls with the aid of Liebherr’s vibrator type LV 20. Additionally, the machine is suitable for other common foundation work, including drilling with continuous flight auger, double rotary head or Kelly bar, soil mixing and piling work with a hydraulic hammer.  🍁
