Features and benefits
Komatsu Traction Control System
Monitor and adjust to changing conditions. Komatsu Traction Control System (KTCS) is designed to provide excellent machine performance in soft and slippery ground conditions without sacrificing steering performance.
Maximize transmission life
Powerful acceleration, smooth down shifting and synchronized engine speed. The K-ATOMiCS transmission features a six-speed, fully automatic transmission with an advanced electronic system to reduce shift shock and torque cutoff for exceptional efficiency.
Greater confidence when traveling downhill
Increase operator confidence when traveling down hill through large capacity, continuously cooled, wet multiple-disk brakes that also function as a highly responsive retarder with 526 horsepower absorption capacity.
Smooth ride over rough terrain
Discover a smooth ride over the rough terrain with front and rear axle hydro-pneumatic suspensions. The rear axles are mounted on a dynamic equalizer structure and the entire system is designed to help reduce operator fatigue while offering a comfortable ride.
Comfortable operator environment
Improved cab entry in front of the front axle. A curved front dash panel. Thoughtful design enhancements throughout the cab provide the operator excellent visibility and a large, quiet environment to promote productivity and comfort.
Efficient loading
Monitor production with a standard, integrated payload meter that displays loaded material weight on the LCD monitor inside the cab. External lamps illuminate green, yellow or red as the payload increases to help prevent under and over loaded haul cycles.
