Liebherr’s Drill Day demonstrates drilling rigs, technology
The concreting process carried out by the LB 24 was also displayed on both a PC and a large screen inside Liebherr Nenzing Crane’s offices. The Liebherr PDE process data recording system allows constant recording of the relevant process data during the working process. All process data are recorded on a memory card and can be imported to the process data reporting software SCULI PDR. This software allows data to be managed, displayed in tables or graphs, and analysed. Alternatively the data can be imported remotely via the LiDAT telematics system.
The LB 20 rotary drilling rig shown at Drill Day was fitted with a tapered auger to drill through concrete. The LB 20 is designed for drilling diameters of up to 1.5m and drilling depths of up to 53m. The rope crowd system offers 20t pull force and guarantees high performance even with the most difficult soils. The kinematics of the LB 20 is 60cm wide and extremely stable. Though powered by a mighty 270kW/362hp Liebherr engine, the efficiency of the drive system ensures lower fuel consumption than comparable machines in this class. The BA 200 rotary drive with 20mt torque guarantees that the installed power of the LB 20 is ideally converted into high productivity. The standard Kelly shock absorber with springs and hydraulic dampers prevents damage to the material and reduces noise emission. Exchangeable drive adapters provide compatibility with other Kelly bar dimensions.
