The two new models use a 386kW SAA6D140E-7 diesel engine, which meets US Tier 4 Final/EU Stage IV emissions requirements. Komatsu says it designed the engine’s diesel particulate filter (DPF) and selective catalytic reduction (SCR) system in conjunction with the engine to ensure optimal efficiency.

Komatsu says the new engine produces fuel savings of up to nine percent for the HD325-8 and up to six percent for the HD405-8 and that these savings were achieved without impacting performance.

"The updated truck models retained their industry leading steering performance and retarding capacity for maximum production," Komatsu America product manager Rob McMahon says.

"The addition of Komatsu’s latest fuel saving technologies and the all-new cab, lower the cost to maximize production and significantly enhance operator comfort at the same time," McMahon says.

The HD325-8 and HD405-8 have payload capacities of 36.5 tonnes and 40 tonnes respectively and both feature Komatsu’s traction control system (KTCS) to help keep the massive loads in line.

KTCS automatically applies independent brake assemblies to achieve the optimum traction in a given situation. Komatsu says that because the system operates without the need for a differential lock-up, the truck’s steering performance is not compromised.

Komatsu has redesigned the cab, reinforcing the soundproofing to achieve sound levels of 78dB (A) when in use. The cab also has a seven-inch LCD colour monitor and a heated and ventilated air-suspension seat.

New angled front access stairs with handrails are now standard on both sides of the trucks and the trucks’ battery box is located at ground level for easy access for maintenance.

There’s no news of an Australian release for the trucks as yet, but we’ll keep you posted when we find out more.
