Human-Machine Interface PCCS (Palm Command Control System)
Gearshift pattern preset function
When the gearshift pattern is set to either <F1-R2>, <F2-
R2> or <F2-R3L> in automatic gearshift mode, the gear is
automatically shifted, reducing round trip repetition work
time and operator's efforts.
ECMV (Electronic Controlled Modulation Valve)
controlled transmission and brakes
Controller automatically adjusts each clutch engagement
depending on travel conditions, providing smooth shockless
clutch engagement, improved component life and operator
ride comfort.
Hydrostatic Steering System—smooth, powerful
turning
The engine power is transmitted to both tracks without
power interruption on the inside track for smooth, powerful
turns. Counter-rotation is available for minimum turning
radius providing excellent maneuverability.
Fuel efficient electronic controlled engine
The Komatsu SAA6D140E-5 engine delivers 264 kW 354
HP at 1900 rpm. The fuel-efficient, powerful Komatsu engine
makes the D155AX superior in both ripping and dozing
operations. The engine is EPA Tier 3 and EU stage 3A
emission regulation certified. The engine is turbocharged
and features direct fuel injection and air-to-air aftercooling to
maximize power, fuel efficiency and emission compliance.
To minimize noise and vibration, the engine is mounted to
the main frame with rubber cushions.
Hydraulic drive radiator cooling fan
The engine cooling fan rotation speed is electronically
controlled. The fan rotation speed depends on engine
coolant and hydraulic oil temperatures, the higher the
temperature the higher the fan speed. This system increases
fuel efficiency, reduces the operating noise levels and
requires less horsepower than belt driven fan.
