Komatsu’s new HM460-6 haul truck delivers more payload and efficiency.
Komatsu has introduced its HM460-6 articulated haul truck to the Australia and New Zealand markets, delivering increased payload, improved fuel efficiency and enhanced operator performance across a wide range of applications.
The next-generation articulated dump truck builds on the longstanding success of the HM400 series, which is widely used across civil construction, quarrying and mining operations.
Komatsu Australia national business manager Nick Vrontas said the new model was developed in direct response to customer demand for greater productivity in the popular 40-tonne class.
“The previous model, the HM400-5, has been the most popular truck in its class for a long time, but customers have been asking for more payload,” Vrontas said. “The HM460-6 delivers that, with a 42-tonne capacity that still meets the needs of those same applications.”
Built for versatility
The HM460-6 is built for quarry, construction, large-scale site development, mining and infrastructure projects where variable terrain, soft ground and haul road conditions can limit productivity. With a higher-rated payload and improved fuel efficiency compared to the Komatsu HM400-5, the truck is designed to deliver a lower cost-per-tonne while maintaining stable, predictable operation throughout the haul cycle.
“Across Australia and New Zealand, you’ll see it used in civil applications like pipelaying, moving material around on construction sites, and even wind farms, as well as in quarries as a haul truck or bin truck and also in mining on subcontractor fleets moving material around,” Vrontas said. “It’s a great, versatile piece of machinery that we know will be popular with our customer base.”
More payload, better efficiency
The HM460-6 increases rated payload capacity while delivering improved fuel efficiency, helping contractors lower cost per tonne and increase overall productivity.
Powered by a new Komatsu engine platform, the truck delivers approximately 9 per cent more horsepower while reducing fuel consumption by around 12 per cent. When combined with the increased payload, this translates to a significant improvement in overall efficiency.
“When you combine the increased payload and reduced fuel use, you see about a 22 per cent improvement in efficiency, which is a big plus for contractors looking to improve productivity and save costs wherever they can,” Vrontas said.
Performance improvements that add up
The HM460-6 also features a redesigned operator environment, with a new cab layout focused on visibility, ergonomics and ease of use. Updated displays, improved sightlines and a range of operator-assist technologies are designed to reduce fatigue and improve overall productivity throughout the shift.
“There are a lot of operator-assist features now, including cruise control for uphill and downhill, automatic retarder braking, rollover prevention system with an inclinometer, KomVision cameras and hill start assist, all designed to make the operator’s day easier so they’re not getting out of the cab fatigued at the end of their shift,” Vrontas said.
Maintenance and serviceability have also been enhanced, with extended service intervals helping to reduce downtime and lower operating costs.
“We’ve extended service intervals with engine oil and filter changes out to 1,000 hours, another thing to help reduce running costs for customers,” Vrontas said.
Tailored for local conditions
Komatsu has also ensured the HM460-6 meets local requirements, with Australia and New Zealand specifications supported through both factory and locally installed features.
“The factory supports Komatsu Australia and New Zealand quite significantly with the amount of extra specification they provide,” Vrontas said. “We get emergency stops, auto-grease, battery and starter isolators as standard, and then locally we fit options to suit customer requirements.”
The HM460-6 has already been introduced in global markets, with units deployed in North America and Europe following its debut at CONEXPO earlier this year. The truck is expected to be available in Australia and New Zealand from June, along with a series of demonstrations and customer events to support the roll out.
“It’s a completely new machine, but it’s built on what we know works – reliability, performance and operator comfort – backed with more payload and better efficiency,” Vrontas said. “We’re confident it’s going to be a strong addition to fleets across Australia and New Zealand.” •
