Technical data

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 63 gal/min

Separate pump for kinematics

36 gal/min

Hydraulic oil tank

159 gal

Max. working pressure

5076 PSI

The cleaning of the hydraulic oils occurs via an electronically monitored
pressure and return filter. Any clogging is shown on the monitor in the
cab. The use of synthetic environmentally friendly oil is also possible.

Swing

Swing ring with triple row roller bearing, external teeth and one swing
drive, fixed axial piston hydraulic motor, spring loaded and hydraulically
released multi-disc holding brake, planetary gearbox and pinion.
Selector for 3 speed ranges to increase swing precision.
Swing speed from 0 – 3.5 rpm is continuously variable.

Pile winch with free fall

Line pull (effective)

17,985 lbf

Rope diameter

20 mm

Rope speed

0-180 ft/min

The winches are 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 of telescopic undercarriage

0 – 1.1 mph

Track force

103,415 lbf

Width of 3–web–grousers

35.4 inch

Transport width

11´5´´

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. A GSM/GPRS/GPS-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 electro-
hydraulic continuous 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/GPRS/GPS-modem
