Liebherr is closing a gap in its compact piling and drilling rig lineup with the new LRB 23.
The new drill rig sits between the LRB 16 and the long-proven LRB 355 in the company’s roster. The machine is an all-rounder for deep foundation work, and offers an engine output of 600 kW, delivering the necessary capacity for all common deep foundation work.
The LRB 23 is capable of drilling with a Kelly drill, double rotary drill, full displacement equipment and continuous flight auger, as well as soil mixing and applications with a vibrator or hydraulic hammer.
As well, its compact design allows for transportation of the LRB 23 in one piece, which simplifies mobilization between jobsites.
The LRB 23’s remote control also simplifies the loading process for transportation, as well as the assembly of the machine.
The advantages of the drill rig are proven in operation. It can withstand high torque, and even Kelly drilling is possible, which is unique for a machine of its size. The rotary drive BAT 300 delivers a maximum torque of 300 kNm.
Locking of the Kelly bar’s telescopic sections is made significantly easier with the aid of the Kelly visualization system in the LRB 23.
hanks to the real-time display of the Kelly bar’s locking recesses on the cabin monitor, the operator is permanently informed about the actual distance to the next locking recess. Furthermore, colour indications inform when the bar can be locked, and false positioning of the Kelly bar during the shake-off process is indicated through a warning signal.
During continuous flight auger drilling, the concreting process is automated thanks to the drilling assistant. All assistance systems contribute to time savings, higher availability of the machine and a significant increase in safety during operation. The newly-designed piling and drilling rig promises precision, high performance and a long service life, according to Liebherr.
Liebherr’s new design
The new LRB 23 also features a new design. All colour compositions in the latest generation combine the classic Liebherr yellow with new black, grey and white accents.
The design reflects how long-standing tradition and company values unite with advanced technologies. The new colour scheme prevails through all product groups and lends the machines a distinctive look and immediate recognition.
As well, the new design focuses on a higher-level emphasis on safety, by incorporating improved platforms and railings on the uppercarriage. Thanks to the additional add-on wing for mounting lights or cameras, the design is more flexible on the whole.
Inside the new cab, the overall concept fits harmoniously together, delivering reduced noise, a panoramic view and operator comfort. This is achieved through a modern air-conditioning system with improved airflow, an optimized field of view and an orthopaedic operator’s seat with integrated heating and cooling.
Additional safety is provided by stone protection, even in the toughest of applications.
