Concept and characteristics LRB 355

The solid undercarriage offers excellent stability and low

ground bearing pressure.

The uppercarriage with its small swing radius enables

operation in restricted space.

Parallel kinematics with a large working area allows to fold

the leader back.

All winches are mounted on the leader for low centre of

gravity and easy operation.

The rigid leader absorbs high torque and is fitted with a

rope crowd system for high pull forces.

The quick change system allows for rapid mounting or

changing of attachment.

The robust universal machine for a wide variety of

applications:

Full displacement drilling

Continuous flight auger drilling

Double rotary drilling

Kelly drilling

Soil mixing

Vibrator slim design

Ring vibrator

Hydraulic hammer

Cutter Soil Mixing (CSM)

LRB 355 with optional equipment

The powerful Liebherr diesel engine is low in emission and

economical through SCR technology.

The optional Eco-Silent-Mode reduces fuel consumption

and noise emission.

The Litronic control with assistance systems supports the

operator:

Joystick control for all machine functions

Leader inclination memory

Centrifugal governor for vibrator

Cruise Control for the drilling process etc.

The PDE process data recording system creates the basis

for a complete documentation of the working processes

carried out. Using the PDR evaluation software this

documentation is given the desired form.

Sophisticated solutions provide safe operation and main-

tenance of the machine:

Cab design for optimum visibility

Acoustic and optic warnings

Rear and side view cameras etc.

Technical description

Control

The control system – developed and manufactured by Liebherr – is

designed to withstand extreme temperatures and the many heavy–

duty construction tasks for which this machine has been designed.

Complete machine operating data are displayed on a high resolution

monitor screen. A GSM/GPRS telematics module allows for remote

inquiry of machine data and operational conditions. To ensure clarity of

the information on display, different levels of data are shown in enlarged

lettering and symbols.

Control and monitoring of the sensors are also handled by this high

technology system. Error indications are automatically displayed on the

monitor in clear text. The machine is equipped with proportional control

for all movements, which can be carried out simultaneously.

Two joysticks are required for operation. Pedal control can be changed

to hand control.

Option:

PDE®: Process data recording

Main winch

Line pull effective (1st layer) 250 kN

Rope diameter 34 mm

Line speed 0-79 m/min

Free-fall function

Auxiliary winch

Line pull effective (3rd layer) 80 kN

Rope diameter 20 mm


Rope crowd system

Crowd force push/pull 400/400 kN

Line pull (effective) 200 kN


Free-fall function

The winches are noted for compact, easily mounted design.

Propulsion is via a maintenance-free planetary gearbox in oil bath.

Load support by the hydraulic system; additional safety factor by a

spring–loaded, multi–disc holding brake. All line pull values are effective

values. The efficiency factor of approx. 25% has already been deducted.

Crawlers

Propulsion through axial piston motor, hydraulically released spring

loaded multi–disc brake, maintenance-free crawler tracks, hydraulic

chain tensioning device.

Drive speed 0 – 2.1 km/h

Track force 681 kN

Width of 3-web grousers (option 800 mm) 900 mm

Option:

Undercarriage with detachable crawlers

Drive speed 0 – 1.85 km/h

Track force 814 kN

Width of 3-web grousers (option 900 mm) 1000 mm

Engine

Engine type Liebherr D 9512 A7-04

Power rating according to ISO 9249 600 kW (805 hp) at 1700 rpm or

750 kW (1006 hp) at 1700 rpm

Fuel tank 1300 l capacity with continuous level

indicator and reserve warning

Engine complies with 97/68 EC or NRMM exhaust certification

EPA/CARB Tier 4f.

The reduced engine speed results in increased fuel efficiency, less noise

emission and longer service life of the engine.

The optional Eco-Silent Mode can be used when the working process

does not require the full engine power. This function further reduces the

engine speed so allowing the machine to operate even more silently and

with enhanced fuel efficiency. The optional Engine Auto-Stop prevents

long idle times after the operator has left the cabin and thus avoids

unnecessary fuel consumption and emissions. As an option a diesel

particulate filter is available (for 97/68 EC engines only).

Hydraulic system

The main pumps are operated by a distributor gearbox. Axial piston

variable displacement pumps work in open and closed circuits,

supplying oil only on demand. Hydraulic pressure peaks are absorbed

by the integrated automatic pressure compensation, which relieves the

pumps and saves fuel.

Main pump capacities 3x 396 l/min

2x 430 l/min

1x 215 l/min

Hydraulic oil tank 1100 l

Max. working pressure 400 bar

Largely dimensioned hydraulic components guarantee a high efficiency

rate and fuel economy.

A system of electronically monitored pressure and return filters cleans

the hydraulic oil. Any clogging is displayed in the cabin. The use of

synthetic environmentally friendly oil is also possible.

Swing

Consists of triple-row roller bearing with external teeth and two swing

drives, fixed axial piston hydraulic motor, spring loaded and hydraulically

released multi–disc holding brake, planetary gearbox and pinion.

Selector for 3 speed ranges to increase swing precision.

Swing speed from 0 – 2.4 rpm is continuously variable.

Noise emission

Noise emissions correspond with 2000/14/EC directive.

Guaranteed sound pressure level LPA

in the cabin 71.8 dB(A)

Guaranteed sound power level LWA

112 dB(A)

Option: Eco-Silent Mode

Guaranteed sound power level LWA

108 dB(A)

Vibration transmitted to the hand-arm system of the

machine operator < 2.5 m/s2

Vibration transmitted to the whole body of the

machine operator < 0.5 m/s2

Process data reporting - PDR (additional equipment) Comprehensive data evaluation and generation of reports on a PC is possible using the software PDR.

Depending on the application the recorded and processed data are displayed on the PDE® touchscreen in the operator‘s cab, e.g. in the form of an

online cast-in-place pile.

At the same time the PDE® is operated using this touchscreen. The operator can enter various details (e.g. jobsite name, pile number, etc.) and start

and stop recordings. A recording of every start-stop cycle carried out in the PDE® is established on a CompactFlash memory card.

The PDE® can be configured in a number of ways, e.g. for the connection of external sensors, for the generation of a simple protocol as graphic file

and/or for a printout directly in the operator‘s cab.

Process data recording system - PDE® (additional equipment)

The Liebherr process data recording system PDE® constantly records the relevant process data during the

working process.

Recordings management - The recordings generated by the PDE® system can be imported and managed

in PDR. The data can be imported directly from the CompactFlash card or via the Liebherr telematics system

LiDAT. Certain recordings, e.g. for a particular day or jobsite, can be found using filter functions.

Viewing data - The data in each record is displayed tabularly. Combining several recordings provides results,

for example, regarding the total concrete consumption or the average depth. Furthermore, a diagram editor is

available for quick analysis.

Generating reports - A vital element of PDR is the report generator, which allows for the generation of

thickness or even the desired logo can be configured. Moreover, the reports can be displayed in different

languages, e.g. in English and in the national language.
