Engine
Water–cooled, V 8 cylinder Liebherr diesel engine, modelD 9408 TI–E, turbocharged with intercooler, power rating according to
ISO 9249, 400 kW (544 HP) at 1900 rpm.Option:Water–cooled, V 12 cylinder Daimler Chrysler diesel engine, modelLOM 444 LA, turbocharged with intercooler, power rating according toISO 3046 IFN, 605 kW (811 HP) at 1900 rpm.The automatic limiting load control adapts perfectly the power of the mainusers to the present engine speed.Fuel tank: 810 l capacity with continuous level indicator and reservewarning.
Hydraulic system
The main pumps are operated by a distributor gearbox. Axial pistondisplacement pumps work in open circuits supplying oil only whenneeded (flow control on demand).The hydraulic pressure peaks are absorbed by the integrated automaticpressure compensation, which relieves the pump and saves f uel.Pump f or working tools: 2x 300 l/min and 1x 400 l/minSeparate pump f or kinematics: 69 l/minSeparate pump f or crowd system: 310 l/minHydraulic oil tank: 1000 lMax. working pressure: 350 barNo auxiliary power packs are required as application specific hydraulicssupply power to all components.The cleaning of the hydraulic oils occurs via an electronically monitoredpressure and return f ilter.
Any clogging is shown on the display in the cab.The use of synthetic environmentally f riendly oil is also possible.
Rope Crowd System
Crowd f orce push/pull: 450/450 kNLine pull (nominal load): 150 kNRope diameter: 24 mmMax. line speed: 0 –87 m/min
Swing
Consists of single row ballbearing, fixed axial piston hydraulic motor,spring loaded and hydraulically released multi–disc holding brake,
planetary gearbox and pinion.Free swing with hydraulic moment control reduces wear to a minimum,because rotation moment is sustained through the hydraulic system bythe diesel engine.Swing speed f rom 0 – 4.5 rpm is continuously variable.
Crawlers
Propulsion through axial piston motor, hydraulically released springloaded multi–disc brake, maintenance f ree crawler tracks, hydraulic chaintensioning device.
Telescopic undercarriage: 0 – 1.5 km/h3–web track shoes: (optional 900 mm) 800 mmTrack force: 630 kN
Control
The control system – developed and manufactured by Liebherr – isdesigned to withstand extreme temperatures and the many heavy–dutyconstruction tasks f or which this machine has been designed. Completemachine operating data are displayed on a high resolution monitorscreen.To ensure clarity of the information on display, different levels of data areshown in enlarged lettering and symbols. Control and monitoring of thesensors are also handled by this high technology system.Error indications are automatically displayed on the monitor in clear text.The crane is equipped with proportional control f or all movements, whichcan be carried out simultaneously.The “Redundant” control system allows restricted operation of themachine in the event of a failure on the electronic base control or itssensors.Two joysticks are required f or operation. Pedal control can be changed tohand control.
Options :D PDE :Process data recordingD GSM modem
Noise emission
Noise emissions correspond with 2000/14/EC directive on noise emissionby equipment used outdoors.
Technical description
Auxiliary winch
Line pull (nominal load): 80 kNRope diameter: 20 mmDrum diameter: 320 mmMax. line speed: 0 –60 m/minThe winches are noted f or their compact, easily mounted design.Propulsion is via a maintenance f ree planetary gearbox in oil bath. Loadsupport by the hydraulic system; additional safety factor by aspring–loaded, multi–disc holding brake.

PDE - Process data recording (Additional equipment)
This module constantly calculates and stores the current working processes.
PDE - diagram
Example of a protocol (in required language):
MeasurementsMeasurements are constantly calculated during the workingprocess. No special measuring process is required. External systems
can also be connected to the system.
Display of measurement dataMeasurement data relevant to the working process is displayed
on the monitor in the cab.
The operator can then control the process and, if necessary,correct it.
Working process interruptionThe working process and the measurement can be interrupted atany time.
The measurements are automatically continued uponresumption of work.
Storage of measurement andmachine data
All data is stored on a memory card. This can be read via a PC.
Thereby an evaluation and processing of data can also beperformed at a later time. For example, f or:
D client certificationsD conveying daily production data, down time, etc.D Soil condition report
Printing data A protocol can be printed out from the cab printer after eachworking process.
Data transmission A GSM modem can be connected to the PDE making longdistance data transmission possible.
