Introducing the HD465-8, a mechanical haul truck engineered for exceptional maneuverability and optimal traction across various ground conditions. Equipped with a seven-speed, fully automatic transmission featuring skip shift functionality, this truck delivers the power and speed required to meet demanding production needs.

Key specifications:

  • Up to 12% reduction in fuel consumption*, ensuring cost-effectiveness and environmental sustainability.
  • Up to 5% more productive*, enhancing operational efficiency and productivity.
  • Enhanced serviceability*, streamlining maintenance processes for increased efficiency.
  • Improved operator environment*, prioritizing comfort and usability for those operating the machine.

*Compared to HD465-7 model.

Product Features and benefits:

  1. MacPherson-Strut-Type Suspension: Enjoy a comfortable ride on uneven roads with the MacPherson-strut-type independent front suspension. This system allows the front wheels to smoothly follow uneven road surfaces, ensuring operator comfort.
  2. Fully Hydraulic Wet Multiple-Disc Brakes: Increase operator confidence at higher downhill speeds with fully hydraulic wet multiple-disc brakes. Continuously oil-cooled, these brakes function as a highly responsive retarder, providing added reliability and stable brake performance.
  3. Automatic Retard Speed Control: Enhance steering focus by utilizing automatic retard speed control. Set downhill travel speed increments to match the optimum slope speed, with automatic speed reduction if oil temperature surpasses a set limit.
  4. K-ATOMiCS Transmission: Komatsu Advanced Transmission with Optimum Modulation Control System (K-ATOMiCS) ensures fuel efficiency, reduces material spillage, and offers a smoother ride. The system automatically selects the optimal gear position based on grade, speed, and acceleration.
  5. Komatsu Traction Control System (KTCS): Engineered for optimal traction in soft or wet road conditions, KTCS monitors wheel slippage at the rear axle. If slippage is detected, brakes are independently and automatically applied to each wheel set.
  6. High Rigidity Frame: Critical areas of the main frame utilize cast-steel components for increased machine durability. This high rigidity frame is designed to withstand loads and shocks, ensuring stability.
  7. Robust Dump Body Design: The dump body is designed with remarkable rigidity and low maintenance costs, constructed from high-tensile-strength steel. Stability and a lower center of gravity are achieved through the standard V-shape body design.
  8. Ergonomically Designed Cab: Prioritize operator comfort with an ergonomically designed cab compartment featuring a convenient control layout. Operator comfort is a key element contributing to operational productivity.
  9. Convenient Access: Simplify machine maintenance with inclined stairs and handrails providing easy access to the cab and service deck. Convenient access contributes to efficient maintenance routines.
  10. Integrated Payload Meter: Manage hauling cycle payloads and analyze production volume with the integrated payload meter. Loaded weight is displayed on the payload display and external lamps in real-time.
  11. Ground-Accessible Battery Compartment: Facilitate daily checks and battery replacement with a ground-accessible battery compartment. Conveniently located at ground level, it ensures easy access for maintenance tasks.
  12. Centralized Greasing Points: Ensure easy accessibility for greasing tasks with ground-level greasing points centralized at three locations. Streamline maintenance procedures for optimal machine performance.
