Technical description

Engine

Power rating according to ISO 9249, 450 kW (603 hp) at 1900 rpm
Engine type Liebherr D 9508 A7
Fuel tank 870 l capacity with continuous level
indicator and reserve warning
Engine complies with NRMM exhaust certication EPA/CARB Tier 3
and 97/68 EC Stage III.

Hydraulic system

The main pumps are operated by a distributor gearbox. A xial piston
displacement pumps work in open circuits supplying oil only when
needed (ow control on demand).
The hydraulic pressure peaks are absorbed by the integrated
automatic pressure compensation, which relieves the pump and
saves fuel.

Pumps for working tools 2x 350 l/min
Separate pumps for kinematics 2x 190 l/min
Hydraulic oil tank 825 l
Max. working pressure 350 bar

No auxiliary power packs are required as application specic
hydraulics supply power to all components.
The cleaning of the hydraulic oils occurs via an electronically
monitored pressure and return lter.
Any clogging is shown on the display in the cab.
The use of synthetic environmentally friendly oil is also possible.

Swing

Consists of single row ballbearing, xed axial piston hydraulic motor,
spring loaded and hydraulically released multi–disc holding brake,
planetary gearbox and pinion.
Swing speed from 0 – 3.3 rpm is continuously variable.

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.
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.
Options :
PDE : Process data recording
GSM modem

Crawlers

Propulsion through axial piston motor, hydraulically released spring
loaded multi–disc brake, maintenance free crawler tracks, hydraulic
chain tensioning device.

Drive speed 0 – 2.3 km/h
Track force 437 kN
Width of 3-web track shoes 700 mm

Noise emission

Noise emissions correspond with 2000/14/EC directive on noise
emission by equipment used outdoors.

Auxiliary winch

Line pull (effective) 50 kN
Rope diameter 17 mm
Drum diameter 420 mm
The winch is noted for compact, easily mounted design.
Propulsion is via a maintenance-free planetar y gearbox in oil bath.
Load support by the hydraulic system; additional safety factor by a
spring–loaded, multi–disc holding brake.

Rope crowd system

Crowd force push/pull 150/200 kN
Line pull (nominal load) 100 kN
Rope diameter 18/20 mm
The ropes are actuated by a powerful hydraulic cylinder.

External sensors

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 star t and stop recordings. A recording of ever y star t-stop cycle carried out in the PDE® is established on a CompactFlash memory card.

The PDE® can be con gured in a number of ways, e.g. for the connection of external sensors, for the generation of a simple protocol as gra­phic  le and/or for a printout directly in the operator‘s cab.

Process data reporting - PDR (additional equipment)

Comprehensive data evaluation and generation of reports on a PC is possible using the software
SCULI PDR.

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

in SCULI PDR. The data can be impor ted 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  lter 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 SCULI PDR is the report generator, which allows for the generation
of individual repor ts. These can be printed out directly or stored as pdf  les. In the process the size, colour,
line thickness or even the desired logo can be con gured. Moreover, the reports can be displayed in diffe­rent languages, e.g. in English and in the national language.
