Komatsu revs ‘safest’ trucks on upgraded braking system

Komatsu has introduced low-emission tier 4 engines that feature enhanced road safety capabilities on two of its haul trucks, the 40-tonne capacity HD405-8 and 63-tonne capacity HD605-8.

Both trucks are equipped with Komatsu traction control systems to provide optimum traction in all road conditions.

Further, the system is supplemented with K-Atomics automated transmission system — producing smoother operation — as well as fully hydraulic wet multiple-disc brakes and retarder.

Richard Feehely, Komatsu Australia’s national business manager, quarries, said, “Operators have unmatched control and safety in even the most difficult operating conditions through our integrated transmission and braking system— which is recognised as being the best in the industry.”

The Komatsu automatic retard speed control system gives better control in downhill rides, including when the truck is fully loaded on steep haul roads.

Feehely said, “Our ARSC lets operators simply dial-in the downhill speed required for safe travel, allowing them to concentrate on steering the truck.”

Additionally, Komatsu’s electronic control system also process all signals captured by vehicle sensors speedily – this gives total control of equipment during all conditions.

Feehely said, “Quarries, contractors, plant hirers and smaller mining operations will be able to further lower their owning and operating costs, while achieving an unrivalled level of control and visibility of their production and operating variables.”

Engine condition information is displayed on the monitor via an on-board network inside the cab, which can be accessed via the KOMTRAX telematics remote monitoring system. This ensures that operators stay well on top of all maintenance requirements.

Feehely said that the new trucks have been designed to deliver the safest, most productive and cost-efficient operation across a wide range of operating conditions, with their ultra-low emissions and even lower fuel consumption.
