LRB 355.1 Piling and drilling rig (LRB series)

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

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

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.

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.

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.

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.

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

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

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

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.
