Liebherr presents the LRB 16, which is an all-round piling and drilling rig for diverse applications within the deep foundation sector. The machine gets its name from the sledge’s travel distance, which is approximately 16m. Special emphasis is on the compact design of the LRB 16 with 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 with the currently valid emission regulations. In comparison to earlier models, the LRB 16 has a reduced engine speed of about 1,700rpm.
The proven 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 12.5m absorbs high torque and is fitted with a rope crowd system for high pull forces of up to 200kN. 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 mounted counterweight, and has a transport weight of only 43.5t. 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.
