475 komatsu dozer vs d11 driver#
It also has low noise levels measuring at 70dB(A) for the driver and a 110dB(A) outside noise level.Īnother great aspect of this piece of earthmoving equipment is its preventative maintenance system which includes oil pressure checking ports, a centralised service station, a modular power train design and enclosed hydraulic piping. With an extra-low machine profile, this Komatsu dozer for sale has a low centre of gravity and an excellent balance. It has an operating weight of 108 390 kilogrammes and a tractor weight of 83 590 kilogrammes.įitted with a SAA12V140E-3 turbocharged after cooled diesel engine, this piece of heavy machinery is a dual tilt dozer, effectively helping to increase your operator’s productivity without increasing the amount of effort that goes into it. What is so cool about this design is that it allows shock loads from the implements to transfer to the dozer’s mainframe, allowing various components – from final drives and steering components to axles – to be isolated from the shock loads. Specially engineered to deliver a maximum service and production life, this Caterpillar bulldozer has a unique design in which the suspended undercarriage along with the elevated sprocket work together in order to not only provide a smoother drive, but also give an increased traction. Note that bulldozers commonly have two primary tools – the ripper and the blade. Because it is a wheeled piece of equipment, these dozers are able to move faster than its tracked counterparts and can move from one job site to another without doing permanent damage to tar roads. These pieces of earthmoving equipment will also have a hydraulic, articulated steering system. Some of these dozers are also equipped with Low Ground Pressure (LGP) tracks (sometimes also referred to as swamp tracks).Ī Wheel Dozer on the other hand will commonly be driven by a four wheel drive system. These tracks also attribute to the dozer’s weight distribution, helping them from sinking in muddy or sandy environments. The Crawler bulldozer, being tracked, has an excellent ground holding capability. While a wheel dozer is able to move on a small axis, the crawler dozers are not. Commonly referred to as a ripper, it is used for loosening densely compacted materials such as soil.Ī Crawler Dozer is a tracked piece of heavy equipment while a wheel dozer features heavy, large tyres, enabling it to move from place to place. This plate is known as a blade and can be used to push material (such as rubble and sand) on a construction site for example.īulldozers will also commonly have a claw-like tool that is mounted to its rear. Of course both of the foregoing numbers include intermediate CPT Rebuilds.Interested in finding a heavy-duty dozer for sale? Today the Truck and Trailer team takes a closer look at what dozers are, highlighting the D475A-5 Komatsu Dozer and the D11T Caterpillar bulldozer, measuring their specs up against each other.Īlso commonly referred to as a bulldozer, a dozer is very simply described as a continuously tracked tractor featuring a large metal plate fixed to its front. Even our 994's we are forecasting a 90,000 hour total life, and I hope to get 100+.
Our haul trucks (789) are planned for 100,000 hours and will likely go more than that, I'd say 120k. That's 6k hours/1 year for the complete machine and 12k hours/2 years for Power Train components.
475 komatsu dozer vs d11 serial number#
In essence it's a CPT Rebuild on steroids and the machine is given a new Serial Number afterwards and the complete machine comes with an original factory warranty. To digress, there is one stage above a CPT Rebuild, that is a Cat Certified Rebuild (CCR). The job is guaranteed and in our case the main components all carry a 12 month warranty, the rest of the machine 6 months.
Right down to the frame and back planned for 24 working days IIRC and brought in under target. Somewhere here I posted photos showing the job on a D10T.
Our target (very much Mine Ops efficiency dependent) is 7,000/year.Ī Certified Power Train Rebuild is done by the Cat dealer. Our machines run 24/7, so 6000 hours/year as an absolute minimum.
