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. Axial 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.
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 planetary gearbox in oil bath.
Load support by the hydraulic system; additional safety factor by a
spring–loaded, multi–disc holding brake.
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
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
Noise emission
Noise emissions correspond with 2000/14/EC directive on noise
emission by equipment used outdoors.
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.
