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

Line speed 0-46 m/min
Rope crowd system
Crowd force push/pull 400/400 kN
Line pull (effective) 200 kN
Line speed 0-70 m/min
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.
