For Rio Tinto, Dozer 79, had built up over 37,000 hours ripping and pushing bauxite at its open-pit operation. The Cat D11T dozer is purpose built to move more material and ensure maximum availability through its planned life cycle, the Caterpillar dealer says. Hastings Deering has been sustain output at Rio Tinto’s Gove bauxite open-pit operation in the Northern Territory of Australia by boosting engine power during the rebuild of dozers. National Group secured the first of these dozers earlier 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 first new generation D11 dozer in the world started work at BHP Mitsubishi Alliance’s (BMA) Blackwater coal mine in Queensland, in 2019. The unit comes with new load-sensing hydraulics, high-horsepower reverse and the latest technology to provide higher material movement at a lower cost per tonne. Time-saving service updates reduce daily maintenance and boost machine uptime. The mine, owned by Stanwell, has a 7 Mt/y thermal coal capability and is in Queensland’s South Burnett Region.Įngineered to be rebuilt multiple times, the new D11 has a redesigned main frame delivering lower total cost of ownership over the life of the machine, Cat says. Instead we offer this photo to explain the principles involved.Stanwell’s Meandu coal mine in Queensland, Australia, has taken delivery of a new Cat D11 dozer from local distributor Hastings Deering.Įnsuring safe and efficient operation, the dozer provides operators with full command, as well as delivering higher productivity at lower cost, Stanwell said. Resilient pads or some other form of cushioning material absorbs shock loads when the blade comes in contact with the tractor to be pushed. The dozer moldboard is hinge-mounted to a special inside push beam. They are always part of a special dozer group which is made predominantly for pushing other Dozers and Self Loading Scrapers when a more tractive effort is required. U-Blades are able to Tilt when equipped with one Tilt Cylinder and Tilt and Tip when equipped with two.Ĭushion Dozers are not available as a moldboard only. They are not well suited to handling large angular objects such as blast rock. They are best suited for loose loads coal, woodchips, and overburden, which are evenly distributed across the face of the moldboard. These blades are designed to push large quantities of granular materials over long distances. Semi-U Blades are able to Tilt when equipped with one Tilt Cylinder and Tilt and Tip when equipped with two. Semi-U Blades can be built with good abrasion resistance for materials like gravel, and with puncture resistance for handling large angular pieces of rock. Straight Dozers are able to Tilt when equipped with one Tilt Cylinder and Tilt and Tip when equipped with two.īuilt much like a Straight Blade but with a deeper profile and closed ends to help keep granular materials in front for long pushes. They are not well suited to handling granular materials since these materials spill off the ends during long pushes. Straight Blades can be made very strong, abrasion-resistant, and puncture-resistant for moving large, sharp, and abrasive objects. This is a good all-purpose blade, especially when equipped with Tilt Cylinders. Ideal for making windrows, digging drainage ditches, backfilling trenches grading roads. The moldboard pivots about its center point to cast materials left or right. Angle Dozers work best handling broken and granular materials, soils, and gravel.
