LB 35 Drilling rig (LB series)

The LB 35 is the successor of the proven rotary drilling rig LB 28-320. Its torque is 350 kNm – a 10 % increase in comparison to its predecessor. Drilling with Kelly equipment, double rotary head and continuous flight auger are common methods. Among its main characteristics is the simple transport including folded leader as well as the wide working area thanks to the parallel kinematics. Additionally, the LB 35 has a robust leader which can easy handle high torques and great tractive forces of the rope crowed system. This ensures particularly fast operating cycles.
Operating weight 95.2 - 111.5 t
Max. torque 347 kNm
Kelly drilling, max. drilling depth 77.5 m
Kelly drilling, max. drilling diameter 4,100 mm

Features

Powerful drive technology

Powerful drive technology

The Liebherr-own and fuel efficient diesel engine generates the required power. In combination with the on-board hydraulics a sufficient amount of performance for various deep foundation works is provided. When using further attachments like casing oscillators, no additional power pack is needed. more

Designed for challenging jobs

Designed for challenging jobs

Drilling requires a robust and torsion resistant leader. Moreover, thanks to its unique parallel kinematics a large operating area is achieved, thus guaranteeing precise and solid working. The telescopic undercarriage and the long crawlers offer a high level of stability.

Innovative crane control

Innovative crane control

The crane control system offers a multitude of programme and control options for various drilling methods. Service and machine data is also provided on color displays. The operator thus benefits from a facilitated handling of the rig. Hence, quick working cycles are achieved.

High service availability

High service availability

A global service network with experienced technicians and fast access to spare parts ensure high machine availability and a long product service life. more

Easy transportation and quick set-up

Easy transportation and quick set-up

Basic machine and leader with all hydraulic hoses connected can be transported in one piece. The minimized assembly work allows for quick and easy transportation of the machine between jobsites. Hence, time and money is saved even before operation starts.

Comfort

Comfort

This includes a modern air-conditioning system with improved airflow, an optimized field of vision and reduced noise protection, as well as an orthopaedic operator’s seat with integrated heating and cooling.

Various drilling axes

Various drilling axes

The leader top is designed for different drilling axes and is therefore suitable for all applications.

Modular design

Modular design

Both the counterweight and the leader are modularly constructed. This enables quick and easy assembly and flexible application.

Rotary drive with selective Kelly shock absorber

Rotary drive with selective Kelly shock absorber

The latest version of the rotary drive has a newly developed Kelly shock absorber, which allows the damping strength to be adapted depending on the respective weight of the Kelly bar.

Accessories

Casing oscillators

Casing oscillators

If required, Liebherr piling and rotary drilling rigs can be equipped with a number of casing oscillators which are operated via the machine’s on-board hydraulics. No external power pack is required which leads to significant cost savings.

Electronic evaluation of working processes

Electronic evaluation of working processes

With the PDE process data recording system machine data is recorded during the working process. With PDR these data can be managed, displayed tabularly or graphically, and analyzed. In combination with the telematics system LiDAT these reports can be easily generated from the office. more

Fleet management and teleservice

Fleet management and teleservice

The data transmission and positioning system “LiDAT” provides important information on the operation of the machine. With these data the operation becomes more efficient. Various additional modules allow machine data reporting or access through service engineers via teleservice. more

Automatic casing drive adapter

Automatic casing drive adapter

The automatic casing drive adapter with remote control for locking and unlocking the casing pipe offers significant advantages in terms of safety as no personnel is exposed to the hazardous area. In addition faster production cycles can be achieved.

Automatic engine stop

Automatic engine stop

The machine can optionally be equipped with an automatic engine stop control. Thanks to this feature it automatically switches off during longer work breaks after evaluating several machine parameters. This is fuel saving and environmentally friendly.

Eco silent mode

Eco silent mode

With the eco silent mode the engine speed can be reduced to a predefined, required level. With this feature a notable reduction in diesel consumption can be achieved without any impact on operational output. Noise emissions are thus also lowered.

Low-head leader system

Low-head leader system

At jobsite conditions with limited heights, such as under bridges or below power lines, the rig can be equipped with a shortened “low-head” leader.

Kelly Visualization

Kelly Visualization

Locking of the Kelly bar’s telescopic sections is made significantly easier due to the Kelly Visualization system.

Remote control

Remote control

The remote control simplifies the loading process for transportation as well as the assembly of the machine.

Drilling Assistant

Drilling Assistant

During continuous flight auger drilling the concreting process is automated thanks to the Drilling Assistant.

Ground Pressure Visualization

Ground Pressure Visualization

The Ground Pressure Visualization calculates the current ground pressure of the machine in real time and compares it with the specified safety limits of the relevant jobsite.

Applications

Wet soil mixing

Wet soil mixing

For wet mixing a self-hardening suspension is introduced into the ground. more

Down-the-hole drilling

Down-the-hole drilling

For down-the-hole drilling a hammer is mounted on the lower end of a drill rod. The hammer is activated by adding compressed air. more

Double rotary drilling

Double rotary drilling

Double rotary drilling combines continuous flight auger drilling with a continuous casing. more

Full displacement drilling

Full displacement drilling

Full displacement drilling is a modification of continuous flight auger drilling. The drilling tool used is a smooth pipe with an auger-type starter piece. more

Continuous flight auger drilling

Continuous flight auger drilling

The loosened soil material is continuously conveyed to the surface using a continuous auger, the so-called continuous flight auger. more

Kelly drilling

Kelly drilling

Kelly drilling belongs to the most common dry rotary drilling methods. Soil and rock material is conveyed to the surface discontinuously with relatively short rotary drilling tools. more
