According to Chris Moroz, Komatsu Australia’s national business manager, construction, the new PC228US-8 excavator completes the Dash 8 range in Australia and New Zealand and is the first Komatsu construction excavator in the range to include the ROPS certification label.
The cab design on the PC228US-8 is the same as that used on the rest of Komatsu’s Dash 8 excavator range, which until the recent issuing of the new ISO ROPS standard for excavators, was marketed as the “Komatsu Safety Cab”. It is also quieter and larger than cabins on other makes of excavator.
The PC228US-8 has an operating weight of 22.53 tonnes, while the long-undercarriage PC228USLC-8 version weighs 23.38 tonnes, making it the largest zero-swing model in the Dash 8 line-up.
It is powered by Komatsu’s ecot3 SAA6D107E-1 turbocharged and after-cooled diesel engine, which, as with others in the Dash 8 range, is fully compliant with Tier 3 emissions requirements.
The PC228US-8 achieves significant reductions in fuel consumption and emissions through the highly efficient matching techniques of the engine and hydraulic units and reduced hydraulic loss, said Moroz.
In addition to full ROPS certification, the PC228US-8’s cab incorporates a large easy-to-read 7-inch TFT liquid crystal display monitor which communicates all key machine operations at a glance, and includes function keys to allow multi-function operation.
