"With the strong focus on local option assembly and commissioning, we were able to deliver on our promised handover date despite the challenges associated with a one-off build of this size and nature," he said. "The co-operation between both parties in respect of local build items prior to the arrival of the machine allowed the build to go to plan," he said. "This new machine the first new D575A-3 sold into Australia joins a used D575A-3 that the customer imported about four years ago, and the two will work alongside each other," said David.Īnother D575A-2 rips cap rock in a nearby mine, while in New Zealand, two Dash 2s are working at the Stockton coal mine on the West Coast of the South Island, again ripping cap rock in an area where blasting is not an option.ĭavid said that Komatsu and the customer worked closely on the delivery of this final D575A-3 dozer to ensure the process went as smoothly as possible. "This machine will be engaged in ripping about 95% of the time, as blasting is not allowed due to the mine's proximity to local residents, along with high-voltage power lines running through the lease. "The machine is particularly well suited to ripping applications, and has proved a vital tool where blasting is not permitted for various reasons, and where ripping is the only alternative," he said. "Throughout its history, a significant proportion of the D575As manufactured were sold to mines and contract miners in Australia, with others going to US coal mines," he said. "The D575A, the largest dozer ever manufactured, was first introduced in prototype form at Conexpo 1981, and was released as a production Dash 2 model 1991, followed in 2002 by the D575A-3." said David Laidlaw, Komatsu Australia's mining product manager for bulldozers and excavators.

That line will likely see more use as the fire spreads east since, according to Williams. 22 miles of dozer line on the southeast end of the fire remain as the current defense for preventing fire from spreading further in the southeast area, yet plans are in place to stretch the dozer line all the way to the Parks Highway.Īnother benefit of the line is that it allows firefighters to quickly and safely move resources to the spreading fire and begin a quick response to the fast moving flames. One benefit of the containment is that efforts can be focused on the areas where the fire is more active. Down south and in the east activity remains and the fire has spread in both directions decreasing the level of containment. The contained part of the blaze exists along the northwest corner. The ground work had at one point estimated containment at 8% according to planning section chief trainee, Darron Williams. Smoke has grounded much of the aerial support, yet the teams on the ground still fight the flames. FAIRBANKS, Alaska (KTVF) - With the Clear Fire continuing to grow and threaten communities in the interior, the battle against the blaze has grown in intensity as well.
