Technical description
Hydraulic system
The main pumps are operated by a distributor gearbox. Axial piston
displacement pumps work in open circuits supplying oil only when
needed (flow 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 239 l/min
Separate pump for kinematics 140 l/min
Hydraulic oil tank 500 l
Max. working pressure 350 bar
The cleaning of the hydraulic oils occurs via an electronically
monitored pressure and return filter.
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/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.

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.
