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 Kelly drilling, double rotary drilling, full displacement equipment and continuous flight auger, as well as soil mixing and applications with a vibrator or hydraulic hammer.

Economic fuel consumption

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

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.

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

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

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.

Attachment recognition

The automatic attachment recognition also records performance figures of the respective attachment.

Recording of working processes (PDE)

With the PDE process data recording system machine data is recorded during the working process.

LIPOS positioning system

Accurate positioning and precise execution of piling or drilling processes.

Remote control

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

Kelly Visualization

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

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.

Vibrating

Vibrating allows for installing and extracting elements using harmonious vibration.

Continuous flight auger drilling

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

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.

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.

Double rotary drilling

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