Known for its maneuverability and tight turning radius, the HD405-8 helps you deliver high productivity and offers impressive durability. A fully automatic K-ATOMiCS transmission with lock-up torque converter, a hydro-pneumatic suspension system and oil-cooled multiple-disc brakes makes this the right choice for a variety of jobs.
Note: *compared to HD405-7
A comfortable ride, even on uneven roads. The MacPherson-strut-type independent front suspension allows the front wheels to follow uneven road surfaces smoothly.
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.
Let your operator concentrate more 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.
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.
KTCS 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.
Cast-steel components are used in critical areas of the main frame where loads and shocks are most concentrated for increased machine durability.
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.
Operator comfort is key to your operation’s productivity. Designed for operator comfort, an ergonomically designed cab compartment has a convenient control layout.
Machine maintenance is made more convenient with inclined stairs and handrails that provide easy access to the cab and service deck.
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.
Facilitate daily checks and battery replacement with a battery compartment located at ground level for convenient access.
Easy accessibility with ground-level greasing points centralized at three locations.
