The rebuild commenced within hours of the 75 tonne main frame arriving at Whyte Gold on one low loader accompanied by another four trucks of essential components. “We had to semi-knock it down at Lyttleton in order to be able to transport it across Arthur’s Pass,” he says. Komatsu territory sales manager for the West Coast Len Higgins says the dozer was fully built up and tested in Japan before it shipped out. Komatsu positioned technicians at Whyte Gold’s purpose-built hard stand to assist with the final construction of the massive machine, which is expected to take two weeks. ![]() The 115 tonne Komatsu D475A-8 is currently being rebuilt at its new base in Rimu after arriving in a five-truck convoy, with the machine broken down into transportable capsules following its arrival at Lyttleton, near Christchurch. He says efficiency of this new dozer, which Komatsu says has “levels of emission control at the leading edge of heavy machine capability”, will help minimise impact on the land as well. To access the site, Whyte will need to use techniques developed to meet increasingly stringent ecological controls, including winding down operations at a nearby site and selling another Komatsu bulldozer. The dozer was delivered to Rimu in a convoy of five trucks “Some say I would be better served with a smaller machine, but this bulldozer can extract substantial material with a single-pass, so it is actually in use far less than any alternative method,” he says. As of season 5, it is the largest dozer featured on the show. He says the Komatsu bulldozer, which is the largest in the Japanese manufacturer’s range, will be central to this. The D475 Dozer is a very large bulldozer manufactured by Komatsu. Whyte plans to cut between 25-35m into the site to reach the new level, which he believes can be worked for at least another eight years. “I figured the old guys didn’t tunnel for nothing.” “Further down there’s a wash with strong content,” he says. The mining company has commenced a new phase of development at the mine, located behind Greymouth in the glacier region of New Zealand’s South Island.Ĭompany principal Iain Whyte has conducted tests which have convinced him that there is plentiful new material lying deeper into the substructure at the site – believing earlier miners only worked the top level of the deposit. It’s powered by a 237-horsepower Komatsu diesel engine and will be in the same. New Zealand gold miner Whyte Gold has taken delivery of one of the first Komatsu D475-A bulldozers to be delivered in the Southern Hemisphere, seeking new deposits at a long-established mine. The D71 will be the largest hydrostatic dozer with factory-integrated machine control on the market, Komatsu says. New Zealand’s biggest dozer, a Komatsu D475A-8, is helping breathe new life into an all-but worked-out gold mine.
