Komatsu is helping keep quarries safe with the latest technologies.
Without dependable machinery, quarry operators risk costly downtime, safety hazards, and avoidable operational hurdles.
Komatsu, a global manufacturer of heavy machinery, understands the demands placed on quarrying operators.
The company recognises that customers increasingly rely on innovative technology to help them work more efficiently, safely, and productively, which is why it has launched the HD605-10 dump truck.
Komatsu product manager of wheel loaders and dump trucks Nick Vrontas said the HD605-10 was developed in direct response to customer feedback calling for faster cycle times without compromising fuel efficiency.
“Based on feedback from our quarrying customers, we wanted to improve the speed of our machines,” Vrontas said.
“The HD605-10 is our quickest, 60 tonne dump truck, and customers can now be satisfied that their production times can be quicker and more efficient, helping them save more money.”
Vrontas said that Komatsu has added several features which operators will appreciate.
“The Hill Start Assist holds the machine still on a hill and automatically prevents the truck from rolling back down the hill when the operator moves their foot from the service brake to the throttle,” he said.
The HD605-10 features increased horsepower and payload capacity, delivering maximised productivity while maintaining low operating costs.
Operators benefit from several new features, including a waiting brake that holds the machine stationary on inclines without requiring constant brake or retarder input.
The auto retard speed control (ARSC) allows operators to set a consistent downhill speed, enabling them to focus solely on steering. Speed adjustments can be made in precise 1km/h increments via the control lever, improving control and safety on varying grades.
The truck’s MacPherson strut-type front suspension incorporates a special A-frame between each wheel and the main frame. This design increases the turning angle of the wheels, resulting in a smaller turning radius, an important advantage in confined quarry environments.
Operator comfort and safety have also been prioritised. The wide Komatsu SpaceCab features intuitive, user-friendly controls and a fully adjustable air-suspended seat designed to reduce vibration and operator fatigue during long shifts. Large front windows and electrically adjustable side windows provide excellent visibility, enhancing on-site safety.
Vrontas said that customer feedback has been “really positive,” and the decision to develop the new model came because of a meeting with relevant stakeholders.
“Komatsu has always been well regarded for its trucks, but customers seem especially pleased with this release,” Vrontas said.
“Major markets, including Australia, the United States, and Europe, collaborated at our Japan factory to identify opportunities for improvement. Speed was the clear focus, and we committed to enhancing performance without sacrificing fuel efficiency.
“Our customers continue to get a good total cost of ownership, with that same reliability and assurance that you’d expect from a Komatsu truck.”
Installed in every HD605-10 unit is Komatsu’s smart quarry site (SQS), a fleet management production tool that Vrontas said provides a “holistic overview” of everything that is being used on site in real-time.
SQS features pre-safety notifications, dashboards that go back in time and analyse key productivity indicators (KPIs) and how machinery is performing.
“SQS is an extremely useful tool for site managers and quarrying managers to get a real-time view of what’s happening without needing to go into the field,” Vrontas said.
“What sets SQS apart is being an original equipment manufacturer. The system was being developed in consultation with customers, to ensure it’s designed to what customers want to see, not what we think they want to see.”
SQS is not limited to Komatsu equipment and can be bolted on to any bit of equipment and mic and be able to get the same amount of data.
“We’ve created a device that allows users to get the most out of their machines, whether its Komatsu equipment or not,” Vrontas said.
“We install SQS to every HD605 that we sell to provide the site the opportunity to trial it if they want.”
