Hydraulic System

The power train consists of two main drives. Each of the two gearboxes
drives three identical pumps which draw hydraulic oil from an
unpressurised hydraulic tank. Open circuit hydraulics provide maximum
cooling and filtering efficiency.

Rated flow (total output) 4200 ltr/min 1110 gpm
Relief valve setting 310 bar 4,495 psi
Swing flow rate 700 ltr/min 185 gpm
High pressure in line filters
one per pump located at the valve blocks
200 microns
Full flow return line filters (10 double elements)
at head of hydraulic tank
10 micron
Case drain/by-pass return line filters 3 micron

The four-circuit system features a load-limiting governor with oil delivery
summation to the working circuits and incorporates pressure cut-off
control. Hydropilot prioritises hydraulic flow giving smooth hydraulic
response, simple hydraulic system layout, and a reduced number of
components. The hydraulic system includes large swing-out vertical airto-
oil hydraulic coolers with temperature-regulated hydraulically driven
fans.

Automatic Centralized Lubrication

Three hydraulically powered Lincoln single line automatic lubrication systems are provided as standard, complete with time and volume variable controls. The two central lubrication circuits and open gear grease circuit are supplied by identical pump assemblies from refillable containers which have a capacity of 3 x 300 litres (3 x 80 gal). Replenishment of the containers is through the Wiggins connections on the service arm.

Operator Cab

The large and comfortable cab is mounted on 18 viscous damping pads and sound insulated. The cab has automatic climate control and is pressurised. The operator’s seat is air suspended, electrically heated and has a lap seat belt and offers multiple adjustments. The trainer seat is also equipped with a seat belt. Low-effort joystick controls are electrohydraulic with foot controls for front shovel clam, crawler and swing brake. Full instrumentation, KOMTRAX Plus and an AM/FM radio with MP3 ready CD player with AUX in is fitted. The windshield wash wiper has two speeds and intermittent operation. Amenities include a refrigerator and storage cabinets. Powered and heated mirrors are adjusted from inside the cab. External metal sun blinds on the cab side window and interna roller blinds on all windows are standard. The left hand window is an emergency exit. All windows are tinted parsol green. The front window is a 19mm thick impact resistant window. A walkway is mounted in front of cabin.
