Liebherr boosts torque on new LB 45 drilling rig

Liebherr has introduced the successor to its LB 36 drilling rig. The new LB 45, introduced at bauma, features higher torque, tackles a wider range of applications and improved operator comfort when compared to its predecessor. 

The name of the new LB 45 id derived from its torque of 450 kNm. That is an increase of about 10 per cent in comparison to the performance of the LB 36.

Both the counterweight and the leader are modularly constructed, which enables quick and easy assembly and flexible application. 

The leader top is designed for different drilling axes and is therefore suitable for all applications. 

Through the enhancement of the drilling axes by 50 cm, the LB 45 can be applied for drilling diameters up to a maximum of 3.3 metres. At the same time, the maximum drilling depth for Kelly drilling — with a 5-fold Kelly bar — has been increased to 100 metres.

The strong winches with a maximum pull force of 42 tonnes enable highest performance even under the most difficult conditions. Furthermore, the noise emission is considerably reduced thanks to their elastic mounting. 

Easier operation 

The ground load-bearing capacity and the monitoring of the ground pressure are decisive for the safe operation of a construction machine. The Ground Pressure Visualization of the LB 45 calculates the current ground pressure of the machine in real time and compares it with the specified safety limits of the relevant jobsite. The ground pressure is displayed in the operator’s cab and the operator is constantly aware of whether the machine is situated in, or is approaching, a critical area. This allows dangerous work stages to be avoided or adapted to in a reasonable amount of time.

Locking of the Kelly bar’s telescopic sections is made significantly easier due to the Kelly Visualization system in the LB 45. Thanks to the real-time display of the Kelly locking recesses of the Kelly bar on the cabin monitor, the operator is permanently informed of the actual distance to the next locking recess. 

Colour indications inform when the bar can be locked. Furthermore, 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. The remote control simplifies the loading process for transportation as well as the assembly of the machine. All assistance systems contribute to time savings, higher availability of the machine and a significant increase in safety during operation. 

The LB 45 new cab 

The machine is equipped with a new cabin concept, which gives the LB 45 an refined appearance and focuses on increased operator comfort. This is achieved through a modern air-conditioning system with improved airflow, an optimized field of vision and reduced noise protection, as well as an orthopaedic operator’s seat with integrated heating and cooling.

Further features for the operator are an optional cooler for provisions as well as a USB port for charging mobile phones.
