New Komatsu HM400-5 Articulated Dump Truck for Sale

Move material across challenging, adverse terrain with the HM400-5 articulated truck. For job sites where roads may not exist or are not well established, this machine was designed and equipped to deliver productive, consistent performance — for operators of all experience levels.

  • Excellent maneuverability
  • Automated powertrain features
  • Customer-approved ride comfort
  • Designed for durability

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 684 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.
