The power train consists of one main drive. Diesel engine or electric motor can be supplied. One gearbox drives three identical main pumps which draw hydraulic oil from an unpressurized hydraulic tank. Open circuit hydraulics provide maximum cooling and filtering efficiency.
The three-circuit Hydropilot system features electronic engine and pump management to optimise hydraulic power for smooth hydraulic action, fast response, simple system layout and a reduced number of components. Filtration is at the oil intake to pumps, valve blocks, heat exchangers and oil tank.
The high capacity engine radiator is cooled by a mechanically driven fan for superior cooling efficiency and requires little maintenance. The hydraulic system includes two large swing-out vertical air-to-oil hydraulic coolers with temperature-regulated hydraulically driven fan.
The undercarriage consists of one center carbody and two track
frames, each side attached by 38 high torque bolts.
Two hydraulically powered Lincoln single line automatic lubrication
systems are provided as standard, complete with time and volume
variable controls. Activity and malfunction events are linked to the
ETM. 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 barrels is through the service center.
The large welded steel cab incorporating the ISO 3449
FOPS Level 2 structure is vibration isolated with 15 viscous
combination pads and sound insulated to 75 dB(A). It is equipped
with automatic climate control and is pressurized. The operatorīs
seat is air suspended, electrically heated and has a lap seat belt.
There is a trainer seat with belt.
Low effort joystick controls are hydraulic with foot controls for
front shovel clam, crawler and swing brake.
Full instrumentation and Electronic Text Monitoring (ETM) are
provided. AM/FM radio with CD player is included. Dual
windshield wipers are synchronized with two-speed and
2 heated rearview mirrors are externally mounted. External metal
sun louvers and internal pull-down sun blinds. Left-hand sliding
window. All windows are tinted parsol green.
The Electronic Text Monitoring (ETM) system, mounted in the operators console, continuously monitors the performance of the engine,
gearbox, autolube and hydraulic systems. Fault messages are immediately available to the operator via a digital display and in the event of
critical malfunctions the engine is also shut down.
The digital storage provides failure summary and analysis, which can be downloaded by laptop computer. This data will assist in predicting
or reducing downtime.
