1 Success through leading technology Thanks to the extremely robust leader and the parallel kinematics Liebherr rotary drilling rigs are enormously versatile and ideal for precise work. The rope crowd system featuring exceptionally high pull and push forces significantly enhances the rigs' performance. The Litronic control system does not only include programs for the application of the various drilling methods but also provides the operator with information on service requirements and possible defaults.
Convincing leader concept The higher the utilization of a drilling rig, the more profitable is its operation. Therefore the kinematics and leaders of Liebherr rotary drilling rigs are designed for a wide variety of applications. More stability for maximum precision The parallel kinematics, which is exclusively applied in the Liebherr rotary drilling rigs, provides the unit with outstanding stability and high alignment forces. It only allows for minimum deformation and thus guarantees maximum precision, e.g.

Electronic control The core of the Liebherr rotary drilling rigs is the Litronic control system. Developed and manufactured by Liebherr, this comprehensive system encompasses all control and monitoring functions and is designed for extreme environmental conditions in tough assignments. Operating comfort and information through Litronic The Litronic control is based on a CAN-Bus system of the latest generation.

Electronic evaluation A modem for remote diagnosis as well as a process data recording system for documentation of the work carried out and a process data reporting software for evaluating the recorded data are available as cartridge. Quality assurance through process data recording (PDE) The process data is constantly measured during the working process. External sensors can also be connected to the system. Measurement data relevant to the working process is displayed on the monitor in the cab.

2 Performance and flexibility through innovation Liebherr rotary drilling rigs were designed for heavy-duty construction tasks in the deep foundation industry and offer a wide range of possible applications. Kelly bars and rotary drives are available in various dimensions and thus ensure maximum utilization and flexibility of the LB series. No existing standard concept was used for its development. The steel structure of the uppercarriage was newly designed to meet with the requirements.
Flexible drilling applications For drilling applications, a robust and torsion resistant leader is most important. For the various drilling tasks powerful single or double rotary drives, Kelly bars, mixing drives as well as a wide range of accessories are available. Flexibility through main winch All winches of the Liebherr rotary drilling rigs are mounted on the leader. Thus, the leader can be adjusted without causing any rope movement.

Design features The design of the Liebherr rotary drilling rigs especially focusses on fulfilling the high quality and performance requirements. Above all, the rigs excel in their stability, precision and longevity. Steel structure All steel components were newly developed and especially designed for the high demands of deep foundation applications. The large cross section allows for optimum force transmission providing less material wear and a longer service life.

Systematic rotary drives Liebherr rotary drives guarantee that the basic machines' excellent performance is ideally converted into high productivity. Efficient rotary drive The rotary drives feature a two-stage gear drive. The drilling speed is continuously controlled by the operator via potentiometer. Thus, it is possible to react flexibly to changing soil conditions and to achieve optimum crowd force.

Several newly developed features Liebherr rotary drilling rigs are full of technical innovations resulting from Liebherr's many years of experience in deep foundation applications. They provide the rigs with excellent performance characteristics and allow for precise handling. Automatic shake-off system While Kelly drilling the auger is normally emptied by rotating it very quickly or through abrupt rightleft-movements of the rotary drive.

3 Cost-effective operation Low weight and compact design are prerequisites for road transportation of the Liebherr rotary drilling rigs in one piece. This minimizes assembly work on the jobsite and saves time and money even before operation starts. Moreover, for rig operation the costs per production unit have been reduced to a minimum. The result is reliable deep foundation machinery with maximum cost effectiveness. 24 Drehbohrgeräte_S24-29.indd 24 24 Drehbohrgeräte_enGB_24-36.indd 22.03.

Efficient transport The quicker a rotary drilling rig can be transported and mobilized, the more economic is its operation – especially on small jobsites. Complete transportation of the rigs lays the foundation for fast and easy assembly. Due to their low weight and favourable dimensions, Liebherr rotary drilling rigs can be easily transported to the jobsite and are ready for operation within a very short period of time. If required, Liebherr also offers self-assembly systems as an option.
Quick and easy assembly Due to their compact design Liebherr rotary drilling rigs can usually be transported in one piece which significantly accelerates their assembly on the jobsite. Assembly without auxiliary crane If the counterweight of a larger unit is transported separately it can be assembled on site using the leader without the need for an auxiliary crane. This saves additional costs. Rotary drive Even the rotary drive can be mounted directly.

Cost-effective operation The costs per performed production unit can be optimized either by increasing the hourly output or by reducing the costs per hour of operation. Liebherr rotary drilling rigs optimally combine both aspects through their exceptional performance and the low operational costs. Well proven components All applied components are designed for reliability and longevity in order to reduce periods of standstill and minimize repair costs.

4 Higher productivity through better comfort The design of the operator's cab aims above all at facilitating the handling of the machine and enabling easy operation for the operator. Ergonomic design In the spacious cab featuring a seat with individual adjustments as well as air conditioning, all operating elements are clearly and ergonomically arranged. All machine movements are controlled proportionally and precisely by two joysticks and three foot pedals.

5 Reliable service Permanent readiness for operation is a major prerequisite of the rotary drilling rigs to enable smooth and efficient application on the jobsite. Downtime is enormously expensive and has to be reduced to a minimum. A tight network of service stations with qualified contacts and well-trained Liebherr service personnel guarantees quick assistance at any time and any location throughout the world.
