  • Up to 7% reduction in fuel consumption*
  • Up to 3% more productive*
  • Enhanced serviceability*
  • Improved operator environment*

    *Compared to HD605-7

Features and benefits

MacPherson-strut-type suspension

A comfortable ride, even on uneven roads. The MacPherson-strut-type independent front suspension allows the front wheels to follow uneven road surfaces smoothly.

Fully hydraulic wet multiple-disc brakes

Give your operator greater confidence at higher downhill speeds with wet multiple-disc brakes. Continuously oil-cooled, multiple-disc brakes function as a highly responsive retarder for added reliability and stable brake performance.

Automatic retard speed control

Let your operator concentrate on steering by simply setting the downhill travel speed at increments of 0.6 mph to match the optimum speed for slope. Travel speed is automatically lowered if oil temperature increases to a set limit.

K-ATOMiCS transmission

Komatsu Advanced Transmission with Optimum Modulation Control System (K-ATOMiCS) helps avoid unnecessary fuel consumption, reduce material spillage and provide a smoother ride for operators by automatically selecting a gear position depending on grade, speed and acceleration.

Komatsu Traction Control System (KTCS)

KCTS is engineered for optimal traction in soft or wet road conditions with a system that monitors for wheel slippage at the rear axle. If slippage is detected, brakes are applied independently and automatically to each wheel set.

High rigidity frame

Cast-steel components are used in critical areas of the main frame where loads and shocks are most concentrated for increased machine durability.

Robust dump body design

Remarkable rigidity and low maintenance cost with a body design made of high-tensile-strength steel. Stability and lower center of gravity through a standard V-shape body design.

Ergonomically designed cab

Operator comfort is key to your operation’s productivity. Designed for operator comfort, an ergonomically designed cab compartment has a convenient control layout.

Convenient access

Machine maintenance is made more convenient with inclined stairs and handrails that provide easy access to the cab and service deck.

Integrated payload meter

Manage the hauling cycle payloads and analyze the production volume and working conditions for specific time periods. Loaded weight is shown on the payload display and external display lamps in real time.

Ground-accessible battery compartment

Facilitate daily checks and battery replacement with a battery compartment located at ground level for convenient access.

Centralized greasing points

Easy accessibility with ground-level greasing points centralized at three locations.
