Efficient in every application The conception of the Liebherr rotary drilling rigs (LB series) is based on Liebherr’s many years of experience with deep foundation applications and considers even the heaviest demands, which are nowadays made on modern rotary drilling rigs. 1 Success through leading technology Liebherr rotary drilling rigs achieve an excellent level of performance in every situation due to leading technology developed in-house. This includes the powerful drive technology, the solid leader design, the electronic control and the reliable machine and process data recording system....

flexibility through Liebherr rotary drilling rigs offer a wide range of possible No existing standard concept was used for their devel- opment. The steel structure of the uppercarriage was newly designed to meet with the requirements. Many in- novations from Liebherr's many years of experience with deep foundation applications were incorporated and all requirements for best performance were uncompromis- ingly fulfilled. Reliable Liebherr components as well as proven Liebherr technology were used to ensure the high quality and longevity of the drilling rigs. Economical transportation, quick and...

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. The process data recording and evaluation systems are available as additional equipment....

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 out- standing stability and high alignment forces. It only allows for minimum deformation and thus guarantees maximum precision, e.g. when installing foundation piles by drilling. Decisive advantages are due to the functions...

Electronic control The core of the Liebherr rotary drilling rigs is the Litronic control system. Developed and manufactured by Liebherr, this comprehensive system en- compasses 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. All information required for the current rig operation such as information on the type of application, machine data, warnings and failure indications are displayed on the large touch...

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. The operator can then control all processes and, if necessary, correct them. The data is stored by...

State-of-the-art drives The series of Liebherr rotary drilling rigs is equipped with powerful diesel engines especially designed for heavy-duty construction tasks. Not only reliability, longevity and ease of service, but also environmental protection was a main focus during their development. The powerful Liebherr diesel engines, offering 180 - 350 kW depending on the machine class, allow operation of rotary drives, double rotary heads or soil mixing drives solely via the machine's on-board hydraulics. No additional power packs are needed. This saves fuel and thus operating costs. Directly compared...

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. Many innovations from Liebherr's many years of experience with deep foundation applications were incorporated...

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. The powerful Kelly winch provides high efficiency during Kelly drilling applications and so offers decisive advantages especially when installing large diameter...

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. Undercarriage The undercarriage was adopted from the proven Liebherr duty cycle crawler cranes and is designed for toughest assignments....
