At MINExpo 2024 in Las Vegas, Komatsu Ltd showcased two new mechanical haul trucks for the North American market, the HD465-10 and HD605-10. These trucks are designed to boost productivity and enhance fuel efficiency across quarry, mining, and aggregate applications. The new models represent a significant upgrade from the previous -8 versions, promising improved performance and operator comfort.
Enhanced Payload Capacity and Speed on Grade
The HD465-10 is a 60-tonne rigid frame truck, while the HD605-10 offers a 70-tonne capacity. Both trucks are equipped with high payload capabilities, making them efficient workhorses for heavy-duty hauling operations. Komatsu has also incorporated increased horsepower and high-strength steel construction to reduce operating weight, allowing these vehicles to deliver excellent speed, even on challenging grades.

Fuel Efficiency Boost with Multiple Operating Modes
To cater to diverse work environments, both the HD465-10 and HD605-10 feature multiple operating modes to optimize fuel efficiency. Operators can switch between ‘economy’ and ‘economy light’ modes depending on the haul load, helping companies reduce overall fuel consumption during lighter tasks. Additionally, an automatic retard speed control system aids in managing fuel use during downhill descents, contributing to improved efficiency and safety.
Operator Comfort and Safety: Ergonomics and New Assist Features
Komatsu’s new trucks come equipped with several operator-friendly enhancements aimed at improving comfort and safety during long shifts. Both trucks feature an ergonomically designed cabin that includes a retractable sun visor and a throttle lock function for reduced operator fatigue. For additional convenience and safety, the trucks are fitted with hill start assist, waiting brake, and a full LED light package. The vehicles’ tight turning radius enables smooth navigation, even on narrow haul roads.
Maintenance Made Simple with Advanced Features
Komatsu has introduced several maintenance-friendly elements with the HD465-10 and HD605-10 models, making them easier to service and maintain in the field. The trucks come equipped with maintenance-free batteries, plastic resin wheel chocks, and brake performance checks. Ground-level Komatsu Oil and Wear Analysis (KOWA) sampling ports are also included to facilitate efficient monitoring of machine health, reducing downtime.
Smooth Performance on Rough Terrain with MacPherson-Strut Suspension
Designed to tackle the uneven terrain often found in mining and quarrying environments, both trucks feature MacPherson-strut-type independent front suspension systems. This allows for a smoother ride across rugged haul roads, reducing strain on the vehicle and enhancing operator comfort.
A New Standard in Rigid Frame Haul Trucks
Komatsu’s introduction of the HD465-10 and HD605-10 mechanical haul trucks sets a new benchmark for performance, fuel efficiency, and operator comfort in the North American market. With cutting-edge features designed to meet the demands of modern mining operations, these new trucks are set to make an impact across quarry, mining, and aggregate sectors, promising to boost productivity and reduce operating costs.
