Hydraulic System

The integrated engine oil and filter system combining the oil stabilising systems, Reserve and Centinel, with Eliminator oil filter extends the oil change interval to 4.000 hours based on oil analysis. The high capacity  by a hydraulically driven fan for superior cooling efficiency.

 

 

Automatic 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 1x 600 and 1x 300 litres (total 238 gal.). Replenishment of the containers is through the Wiggins connections on the service arm.

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)

6210 l/min

1,640 gpm

Relief valve setting310 bar4,495 psi
Swing flow rate1035 l/min273 gpml
High pressure in line filters one per pump located at the valve block 200 microns

Full flow return line filters at head of hydraulic tank

10 microns

Case drain/by-pass return line filters

3 microns

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 air-to-oil hydraulic coolers with temperature-regulated hydraulically driven fans.

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 internal 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.

Major cab engineering standards are:

  • ISO 3449 Falling Objects Protection Structure (FOPS)
  • ISO 6396 Noise in operator’s cab is max. 75 dB(A)
  • ISO 2631-1 Whole body vibration and shock below 0,5 m/sÇ
  • SO 5349-1 Hand-lever vibration lower than 2,5 m/sÇ
  • ISO 10263-4 Heating and air conditioning second heater or air conditioner as option
