![]() On the first pass, operate the dozer in first gear, aiming to fill the blade as fast as possible and start a spoil pile (if you're operating a small or medium-sized tractor, you can shift to second gear). Start behind the the spot where you intend to cut-about two tractor lenghts. The less time you spend driving backwards, the more you can slow down wear on the track.ġ. We've found this to work well because when you work front to back, you limit the amount of time you spend operating the machine in reverse. If you're looking to maximize productivity and decrease undercarriage wear, we recommend dozing front to back. ![]() When digging a slot, dig until you've reached the height of the blade and then move on to the next slot. It can also help to increase the blade load by up to 30 percent. Working in the slot helps to decrease dirt or material from spilling from the blade. ![]() It's important to work in the slot by dozing front to back. But in the meantime, below are several bulldozer operating tips to keep you safe and your machine running as smoothly and efficiently as possible. This takes time, so don't stress if you don't have a handle on it right away. After you've clocked in several days in the driver's seat, you should be able to have an intuitive feel for how the machine should run. The second D11 dozer is expected to be commissioned onsite at Blackwater in January.If you're new to operating a dozer, perhaps the most important thing you'll want to do is to get a sense of how the machine should look, feel, sound and smell (yes, smell) when it's running smoothly. They are far, far more productive which reduces the cost per tonne.” “The best thing here is that it still handles like a U-Blade and can go into the same applications. National Group has lined up all six dozers to be fitted with the new Reclamation blade, or XU Blade, which takes the dozer from a 34 cu.meter blade, to a 42.2 cu.m, according to Garea. It’s a beefed-up frame that now does both.” Jason Garea, Mining Account Manager at Hastings Deering, said: “There is a single frame now used between both the D11 standard dozer and the carry dozer applications. “We expect to lower maintenance and repair costs by up to 5% thanks to a new case and frame design, improved bearings, redesigned pin joints, and a 30% larger oil pan.” Caterpillar has developed this machine to ensure faster cycle times to produce more dirt at a lower cost per tonne, National Group added.Īckroyd said the contribution the dozers will add to production and efficiency will boost overall performance on site. ![]() ![]() In a Hastings Deering release in mid-December, National Group’s Managing Director, Mark Ackroyd, said: “The D11 is the industry’s best large dozer so it was a logical choice for us to bring in six new dozers to add to our expansive fleet.”Īlong with load sensing hydraulics reducing fuel burn, the new D11 will extend out component life from fuel burn to overhaul, according to the company. This would have seen the machine receive new load-sensing hydraulics and new drivetrain components among other additions.īMA’s Blackwater coal mine, in Queensland’s Bowen Basin, produced close to 2.1 Mt of coal in the most recent September quarter, according to BHP. While the specifics of this new dozer are not yet known, Cat did plan to launch an update to its D11 earlier this year. National Group secured the first of these dozers earlier this month from Cat dealer Hastings Deering as part of an order that would see six of these machines hauled by its National Heavy Haulage subsidiary, the company said. The first Caterpillar new generation D11 dozer in the world has started work at BHP Mitsubishi Alliance’s (BMA) Blackwater coal mine in Queensland, Australia, according to mining, resources, transport and logistics group National Group. ![]()
