making the grade

Aimed primarily at contractors, the new GD655-7 grader from Komatsu has a SAA6D107E-3 Tier 4 Final-compliant variable horsepower engine, rated at 134–165kW (depending on gear and operating mode) and has an operating weight of 19.3 tonnes with rear ripper. Komatsu’s national business manager, government and construction graders Phil Atley says the GD655-7 grader represents a significant technology step forward in grader design and ease of operation. Technology innovations include an all-new operator station, with features such as EPC (electronic proportional controls) for blade and ripper functions and the option of dual-function palm controlled steering or a conventional steering wheel. “Our EPC palm control systems greatly cut down operator effort, reducing hand/wrist movements by 95 per cent, and resulting in far lower operator fatigue and improved jobsite safety,” Atley explains. “In addition, this new grader…

electric behemoth

A quarry in Biel, Switzerland, is operating the world’s largest electric vehicle, a 110-ton dump truck, to haul lime and marl off the side of a mountain to a cement factory. The dump truck, at 45 tons, ascends the 13 per cent grade and takes on 65 tons of ore. With more than double the weight going back down the hill, its regenerative braking system recaptures enough energy to recharge the eDumper. The Elektro Dumper – eDumper for short – made by Kuhn Schweitz, is based on a Komatsu HB 605-7 and comes in at 30 feet long, 14 feet wide and 14 feet tall (9.1m x 4.3m x 4.3m). The tyres are six feet high (1.8m), and the dump bed reaches to more than 28 feet (8.5m), fully raised. Kuhn Schweitz adds a…

next level

A regulation that came into effect last year requires Environmental Protection Agency (EPA)-licensed businesses in New South Wales to purchase Tier-4 equipment. Select Kobelco Tier-4 models are also available with the Trimble-ready Earthworks System. “Kobelco has a long history of pioneering fuel-efficient technology that balances environmental initiatives in its excavator line,” Kobelco Australia general manager of sales and marketing Doug McQuinn explains. “This new range of Tier-4 Final compliant excavators is the next step in our pioneering evolution.” The new type of Tier-4 compliant engine is fitted with a diesel oxidation catalyst and a selective catalytic reduction device to control emissions without using a diesel particulate filter. It has a large-capacity diesel exhaust fluid/urea tank, extending intervals between fill-ups and resulting in a NOx reduction rate of about 88 per cent, compared to previous models,…

perfect pick

When Aaron Wilde decided it was time for him to branch out on his own as Azza’s Mini Diggers, he investigated which type of equipment was going to be the best investment. He also wanted machinery that would let him perform excavation and earthworks tasks as quickly and efficiently as possible. With some experience in operating small excavators, he had a clear idea of what he wanted: a gutsy compact excavator that would allow him to dig deep trenches for one of the local plumbing contractors and a high performance tracked compact loader to move material is off-site as quickly as possible. After shopping around, Wilde decided to invest in a new Takeuchi TB 235 hydraulic excavator, followed soon after by the addition of a Takeuchi TL6R compact track loader. “Previously, my…

machine monitoring

MineWare is in the process of installing 23 Argus hydraulic monitoring systems in Australian mining contractor Downer’s fleet. MineWare vice president marketing and sales Roy Pater says the adoption of Argus would deliver significant productivity and efficiency gains for Downer. “Our technology will assist Downer to improve productivity and mine compliance across eight Australian sites in coal, gold, magnetite and iron ore,” Pater says. Argus delivers an increase in the productivity of between 3 to 16 per cent, significantly lowering the cost per ton of material moved, says MineWare. “Mining companies like Downer are looking for innovative ways to improve productivity for their customers by leveraging what digitisation has to offer. Our customers that have done this achieve a real competitive advantage,” Pater explains. Downer technology support specialist Nicholas Duggan says the company selected MineWare…

reuse, recycle

With six towns and seven villages spread across 6,300 square kilometres on the south coast of New South Wales, Bega Valley Shire Council was facing the task of repair and replacement of large sections of concrete kerbing ahead of some major road reconstruction projects. “As part of the solution of replacing these concrete assets, we wanted to look at the possibility of reusing as much waste material as possible, which makes sense both from a cost and environmental viewpoint,” Bega Shire works engineer Jason Heffernan explains. “Due to the volumes involved, concrete recycling was targeted as a priority so we spoke with our regular contractors to see what could be achieved. Michael Grant of Bega Bobcats came up with a practical solution that has been working very well for us.” The solution came…
