Technical data
Engine
Power rating according to ISO 9249, 450 kW (603 hp) at 1900 rpm
Engine type Liebherr D 9508 A7
Fuel tank 800 l capacity with continuous level
indicator and reserve warning
Engine complies with NRMM exhaust certication 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 pump for kinematics 190 l/min
Hydraulic oil tank 825 l
Max. working pressure 350 bar
No auxiliary power packs are required as application specic
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.
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 modem allows for remote inquiry of machine
data and error indications. 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
Kelly winch with free fall
Line pull (effective) 160 kN
Rope diameter 26 mm
Line speed 0 - 94 m/min
Auxiliary winch
Line pull (effective) 80 kN
Rope diameter 20 mm
Drum diameter 320 mm
Line speed 0 - 73 m/min
Swing
Consists of single-row ball bearing with internal teeth, xed axial piston
hydraulic motor, spring loaded and hydraulically released multi–disc
holding brake, planetar y gearbox and pinion. Selector for 3 speed
ranges to increase swing precision.
Free swing reduces wear to a minimum because rotation moment is
sustained through the hydraulic system by the diesel engine.
Swing speed from 0 – 3.7 rpm is continuously variable.
Crawlers
Propulsion through axial piston motor, hydraulically released spring
loaded multi–disc brake, maintenance free crawler tracks, hydraulic
chain tensioning device.
Drive speed 0 – 1.5 km/h
Track force 632 kN
Width of 3-web track shoesn 700 mm 800 mm 900 mm
Rope crowd system
Crowd force push/pull 300/300 kN
Line pull (effective) 150 kN
Rope diameter 24 mm
Line speed 0 - 60 m/min
The ropes are precisely actuated via a powerful winch.
The winches are 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. All line pull values are
effective values. The efciency factor of approx. 25% has already
been deducted.
Noise emission
Noise emissions correspond with 2000/14/EC directive on noise
emission by equipment used outdoors.
