Komatsu Australia have released another giant and powerful mining excavator. It weighs up to 405 tonnes and is powered by a Komatsu SDA16V160E-2 engine rated at 1400 kW.

Promising higher productivity, reduced maintenance costs, increased reliability and upgraded safety features, this new PC4000-11 Tier 2 mining excavator is a step up from its 2016 predecessor. While based on the 2016 model, the main difference lies within the new PC4000-11’s Tier 2 emissions standard engine, where the earlier model sported a Tier 4 Final engine fitted to it.

“Komatsu can now supply the latest design and technology with a Tier 2 option to Australian mines not requiring the Tier 4 PC4000-11 model,” said Michael Hall, Komatsu Australia’s National Product Manager (Mining).

And soon Aussie miners will be experiencing these new and improved machines for themselves. A number of upgrades enhance safety standards for both operators and maintenance crews. One of these upgrades includes the 45-degree stairway access stairs and factory-fitted exit ladders.

“Another safety advance is a new emergency egress system, incorporating emergency exits on two sides of the machine, ensuring high safety standards for all personnel on the machine,” said Hall.

Other safety enhancements include:

  • 19mm thick impact-resistant glass installed into the cab’s front window
  • A flip-down two-piece ladder, with anti-slip surfaces
  • A new lighting system including 14 high-performance working lights

Mr Hall says the potential for this model in Australia is exciting. “We see excellent potential for this model, and are keen to see the advantages and improvements it delivers used in mining operations in Australia.”

The PC4000-11’s upgraded features include:

  • The highest digging forces in its class, both in backhoe and face shovel configs
  • An updated, easy-to-maintain design makes serviceability simpler
  • A simplified Komatsu control system helps enhance reliability
  • Extended oil change intervals combined with safer machine access

“The PC4000-11 Tier 2 is fitted with Komatsu’s latest KOMTRAX Plus remote monitoring system, providing remote monitoring information about the machine’s performance and operating status,” Mr Hall said.

“As well, the machine is Modular Mining’s ProVision ready, allowing it to incorporate a machine guidance system that integrates with mine planning software.”

“It is also ready for MineWare’s Argus Payload System, allowing accurate, reliable payload measurements, so operators can optimise loading to required truck payloads,” he said.
