New piling and drilling rig: LRB 19

The LRB 19 can be used for a wide range of applications in deep foundation work: For piling or vibrating applications, the all-rounder is equipped with the H 6 hammer or the LV 23 and LV 23 F vibrators, all from Liebherr. Drilling with Kelly equipment, double drilling head, full displacement equipment and continuous flight auger or soil mixing are further areas of application. The name LRB 19 reflects the maximum travel distance of the sledge: 19 metres.

The various attachments can be easily exchanged using the hydraulic quick connection system – without tools and without the driver having to leave the cabin. All hydraulic, mechanical and electrical connections are automatically coupled. This significantly reduces the set-up time and prevents connection errors. An improved hose guide further optimises the work process. A new hose sledge ensures that there are no more obstructive hoses during use, which makes the installation of sheet piling in particular much easier. When drilling, the optional pulling device can increase the pull force of the LRB 19 by 110 kN.

The new piling and drilling rig scores with a powerful 450 kW diesel engine, the BAT 180.1 rotary drive with a maximum torque of 180 kNm as well as a low transport weight of 48.2 tonnes including eight tonnes of counterweight and auxiliary winch. The compact design allows for transportation in one piece with the vibrator attached, making mobilisation between jobsites straightforward and more flexible. The remote control simplifies the loading process for transportation as well as the assembly of the machine.

The LRB 19 has a self-assembly system for the counterweight. This can be easily lifted using the leader of the LRB 19, which means no additional crane is required for assembly. The all-round platform with railings on the uppercarriage ensures both high accessibility and safety during maintenance work or inspections on the machine. The optimised arrangement of the LED headlights ensures the best possible visibility in the work area, even at night.

Digital assistance systems for highest efficiency and safety

All well-known Liebherr assistance systems for deep foundation applications are available for the LRB 19. The LIPOS positioning system uses the latest satellite technology to support the operator in precisely aligning the attachment tools during drilling or piling operations. During continuous flight auger drilling the concreting process is automated thanks to the drilling assistant. The pre-defined parameters are implemented by the control system. These can also be adjusted during the drilling process, if necessary. The vibro-replacement process also runs automatically, thanks to the vibro-assistant.

Working area restriction helps the driver to monitor the rotation range, working radius or machine height (height adjustment). As soon as the driver tries to move the machine into the pre-defined restricted area, it stops automatically and thus prevents possible collisions. Other assistance systems such as ground pressure visualisation or eco-silent mode increase the efficiency of the machine and the comfort of the operator. 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 LRB 19 convinces through precision, high performance and a long service life.
