The new Liebherr LB 45 drill rig delivers a torque of 450 kNm, an increase of approximately 10% in comparison to the LB 36. Both the counterweight and the leader of the LB 45 are modularly constructed, thus allowing for quick and easy assembly and flexible application. The LB 45 is scheduled to be available globally starting from autumn 2019 (around September onwards).
The LB 45’s leader top is designed for different drilling axes, making it suitable for a wide range of applications. Through the enhancement of the drilling axes by 500 mm, the new rig can be applied for drilling diameters up to a maximum of 3.3 m. At the same time, the maximum drilling depth for Kelly drilling with five-fold Kelly bar has been increased to 100 m. The strong winches with a maximum pull force of 42 t enable excellent performance under difficult conditions. The noise emission is also considerably reduced, thanks to their elastic mounting.
Like the LB 16 unplugged, the LB 45 is equipped with the Ground Pressure Visualisation system, which calculates the current ground pressure of the machine in real time and compares it with the specified safety limits of the relevant jobsite. The LB 45 drill rig is also fitted with a new cabin concept – same as LB 16 unplugged - for greater operator comfort.
Locking of the Kelly bar’s telescopic sections becomes significantly easier due to the Kelly Visualisation system. With the real-time display of the Kelly locking recesses of the Kelly bar on the cabin monitor, the operator is always informed of the actual distance to the next locking recess.
During continuous flight auger drilling the concreting process is automated, thanks to the Drilling Assistant system. The remote control simplifies the loading process for transportation as well as the assembly of the machine.
