Automatic lubrication

Two hydraulically powered Lincoln single line automatic lubrication systems are provided as standard, complete with time and volume variable controls. The central lube grease system is supplied from a refillable 200 litre (53 gal.) barrel. A second, identical system supplies open gear lubricant to the swing ring teeth through a lube pinion. Replenishment of the containers is through the Wiggins connections on the service arm.

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 Mesabi engine radiators are cooled by a hydraulically driven fan for superior cooling efficiency.

Hydraulic System

The power train consists of one main drive. One gearbox drives four identical pumps which draw hydraulic oil from an unpressurised hydraulic tank. Open circuit hydraulics provide maximum cooling and filtering efficiency.

Rated flow (total output)4.140 ltr/min1,096 gpm
Relief valve setting310 bar4,495 psi
Swing flow rate1.590 ltr/min420 gpm
High pressure in line filters one per pump located at the valve blocks 200 microns
Full flow return line filters (4 elements) 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 swingout 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 an 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 lap seat belt. Low-effort joystick controls are electro-hydraulic 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 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. A walkway is mounted in front of cabin.

Major cab engineering standards are:

  • ISO 3449 Falling Objects Protection Structure
  • ISO 6396 Noise in operator’s cab is 75 dB(A)
  • ISO 2631-1 Whole body vibration and shock below 0,5 m/s²
  • ISO 5349-1 Hand-lever vibration lower 2,5 m/s²
  • ISO 10263-4 Heating and air conditioning / second heater or air conditioner as option
