Product Features and benefits:
Komatsu Traction Control System (KTCS): Adapt to changing conditions seamlessly with the Komatsu Traction Control System. Specifically designed to deliver exceptional machine performance in soft and slippery ground conditions, KTCS ensures optimal traction without compromising steering performance.
Maximize Transmission Life with K-ATOMiCS: Experience powerful acceleration, smooth downshifting, and synchronized engine speed to maximize transmission life. The K-ATOMiCS transmission features a six-speed, fully automatic design with an advanced electronic system, reducing shift shock and torque cutoff for outstanding efficiency.
Greater Confidence on Downhill Travels: Boost operator confidence during downhill travels with large-capacity, continuously cooled, wet multiple-disk brakes. These brakes serve as both highly responsive retarders and absorbers, providing 684 horsepower absorption capacity for enhanced control.
Smooth Ride Over Rough Terrain: Enjoy a smooth ride over rough terrain thanks to front and rear axle hydro-pneumatic suspensions. Mounted on a dynamic equalizer structure, the rear axles contribute to reduced operator fatigue, offering a comfortable ride for increased productivity.
Comfortable Operator Environment: Providing an improved cab entry in front of the front axle, a curved front dash panel, and thoughtful design enhancements throughout, our articulated trucks offer operators an excellent visibility and a spacious, quiet environment. This promotes both productivity and comfort during operation.
Efficient Loading with Integrated Payload Meter: Monitor production efficiently with the integrated payload meter, displaying loaded material weight on the LCD monitor inside the cab. External lamps illuminate in green, yellow, or red as the payload increases, preventing under and over-loaded haul cycles.
