LRB 23 Piling and drilling rig (LRB series)

The compact piling and drilling rig type LRB 23 closes the gap between the LRB 16 and the long-proven LRB 355. An impressive engine output provides the all-rounder with the necessary capacity for all common deep foundation work, such as drilling with a Kelly drill, double rotary drill, full displacement equipment and continuous flight auger, as well as soil mixing and applications with a vibrator or hydraulic hammer.

Max. torque 300 kNm
Max. crowd force 320 kN
Engine power 600 kW
Pile driving with vibrator slim design, max. pile length 22.0 m

Features

Easy transportation and quick set-up

Easy transportation and quick set-up

Basic machine and leader can be transported in one piece with all hydraulic hoses connected. The minimized assembly work allows for quick and easy transportation of the machine between jobsites.

Safe access

Safe access

Side platform, railings and ladders are fully integrated in the new machine design and no longer need to be removed for transport. more

High operator comfort

High operator comfort

The innovative cabin design includes a modern air-conditioning system and an optimized view from the cabin, as well as an orthopaedic operator’s seat. All switches, joysticks and pedals are ergonomically positioned.

Economic fuel consumption

Economic fuel consumption

Innovative hydraulic concepts achieve high performance and keep fuel consumption low, despite reduced engine power.

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

Cruise Control

Cruise Control

Cruise Control is available for automatic piling and drilling processes and allows for values such as pull-down speed and rotational speed to be programmed in advance. more

Obstacle recognition

Obstacle recognition

An improvement for slurry wall application is the obstacle recognition, which enables the timely detection of obstacles in the soil. This protects both the attachment and the basic machine.

Optional equipment

Rear supports

Rear supports

The robust undercarriage offers excellent stability, which can be further increased with the optional rear supports.

Remote control

Remote control

The complete loading and set-up processes can be carried out via remote control, which means only one person is required. more

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.

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.

Kelly Visualization

Kelly Visualization

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

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.

Applications

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

Vibrating

Vibrating

Vibrating allows for installing and extracting elements using harmonious vibration. 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

Impact driving

Impact driving

Impact driving uses a hydraulic hammer for the installation of various types of pile. The hammer’s ram mass impacts on the pile. 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

Double rotary drilling

Double rotary drilling

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

Wet soil mixing

Wet soil mixing

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

more
Vibro-replacement

Vibro-replacement

Coarse extraneous material is filled into the vibrating hopper and a load-bearing gravel or crushed stone column is produced.

more
Cutter soil mixing

Cutter soil mixing

Cutter soil mixing combines technologies of soil mixing and slurry wall production.

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.
