The integrated engine oil and filter system combining the oil stabilizing
systems, Reserve and Centinel, with Eliminator oil filter extends the
oil change interval up to 4000 hours based on oil analysis. The high
capacity Mesabi engine radiators are cooled by a hydraulically driven
fan for superior cooling efficiency.
The power train consists of one main drive. One gearbox
drives four identical pumps which draw hydraulic oil from an
unpressurized hydraulic tank. Open circuit hydraulics provide
maximum cooling and filtering efficiency.
The four-circuit system features a load-limiting governor with
oil delivery summation to the working circuits and incorporates
pressure cut-off control. Hydropilot prioritizes 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.
Undercarriage consists of one center carbody and two track
frames, each side attached by high torque bolts.
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 liter 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
The large and comfortable cab is mounted on 18 viscous damping pads and
sound insulated. The cab has an automatic climate control and is pressurized.
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 electric over 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.
KOMTRAX Plus is designed for Komatsu mining equipment to provide
real time information about the operating status of the machine via
a colored display. The integrated digital storage provides a full event
history and trend data, which can be downloaded by laptop, optional
are W-LAN or satellite modem.
