Komatsu has introduced two new -10 mechanical haul truck models to its North American lineup.
Offering an upgrade from the previous -8 models, the 60-ton HD465-10 and 70-ton HD605-10 mechanical haul trucks were introduced to the Canadian and United States markets at MinExpo. Mining Trucks Cost
The new haul trucks are designed to increase productivity and improve fuel efficiency in quarry, mining and aggregate applications.
“Komatsu is committed to developing equipment that supports our customers’ needs and helps them be most effective at the job site,” said Madeline Pearce, Product Marketing Manager for Komatsu. “The fuel efficiency and productivity benefits these products provide — combined with a number of operator-designed features — demonstrate that commitment. We are excited to provide these new models of haul trucks to support our customers across North America.”
The HD465-10 is a rigid frame machine powered by an 818 hp engine. With a 105,400-kg operating weight, the truck features a capacity of 48.5 cubic yards and efficient hauling capabilities. Compared to the -8 model, the HD465-10 delivers 5.5 per cent more horsepower, a 1 per cent fuel efficiency improvement and is up to 6 per cent more productive when hauling loaded uphill compared to the -8 model.
The HD605-10 mechanical haul truck is also powered by an 818 hp engine and features a 114,400 kg operating weight and a 56.3 cubic yard capacity.
Compared to its predecessor, the truck delivers a 12 per cent increase in peak torque, an 8 per cent boost to productivity when hauling uphill and a 5.5 per cent increase in horsepower.
Both trucks offer a tight turning radius of 8.7 metres for easy navigation on narrow haul roads and ergonomically designed cabin features for operator comfort during long shifts.
With increased horsepower and higher-strength steel for reduced operating weight, the machines are built to provide excellent speed on grade.
Additional features include a MacPherson-strut-type independent front suspension that allows the vehicle to traverse uneven road surfaces, the ability to regulate fuel efficiency for lighter work with economy and economy light modes and controlled downhill descent with the automatic retard speed control function.
On both models, the dump body has been re-engineered using higher-tensile strength steel to reduce weight, increase speed on grade and improve fuel efficiency. Stability is improved due to the lower centre of gravity through a standard V-shape body design.
Haul Truck New operator features include hill start assist, throttle lock, a retractable sun visor and waiting brake. Beneficial maintenance elements include a full LED light package, plastic resin wheel chocks, maintenance-free batteries, brake performance checks and ground level Komatsu Oil and Wear Analysis (KOWA) sampling ports
