![]() ![]() 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. 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. Cat started the nomenclature change process last year and should be fully transitioned by the end of next year.Our machines run 24/7, so 6000 hours/year as an absolute minimum. Eventually the dozers will be known by just their size class, D5, D6, D11 and so forth. ![]() The D6K will become the D4, the D5K will become the D3, D4K will become the D2 and D3K will become the D1. A grab bar in the back gives you a steady hold when refueling as well.Īs mentioned, the D5 will replace the D6N and reflects Caterpillar’s plan to make dozer model names simpler. Safety conscious operators will also appreciate a “halo” grab bar that runs completely around the circumference of the cab-something to hang on to when cleaning the cab glass. A high-def rearview camera brings up a panoramic view behind the dozer anytime you put it in reverse. The seat is heated and ventilated and adjustable 13 ways. A steeper slant over the hood also improves visibility to the blade. They also moved the exhaust stack to the side and integrated the A-pillar into the ROPS to improve visibility. The old D5 had one of the smallest cabs in its class while the D6N had one of the largest. The new purpose-built push arm configuration for the SU blade puts the center of gravity a bit further forward for better cutting and penetration. ![]() If you need to meet regional transport requirements, a folding VPAT blade is available. The D5 is available in standard or low ground pressure (LGP) configurations with either a push arm/SU blade (semi-U shaped) or a variable pitch angle tilt (VPAT) blade. A fully automatic, 3-speed transmission shifts gears seamlessly allowing for smoother acceleration and faster cycle time. Manual shifting has been eliminated on the D5. The Steering Radius Control uses sensors on the steering and the decel pedal to automatically downshift anytime you want to crank the dozer around in a tight turning radius. And Hill Hold automatically engages the brakes to hold you in position while you’re in neutral. Hill Descent Control maintains your speed when cresting a hill and heading down without the need to jump on the service brake. The extra weight and power add up to a 4.5 percent increase in drawbar pull and 2.5 percent improvement in productivity, says Meeker.Ĭat also put together a package of enhancements it calls “enhanced power train control” to drive additional efficiency in dozing operations with the D5. In similar fashion the Traction Control temporarily reduces track power when slippage is detected so you can adjust the blade load to prevent productivity-robbing slippage. The Blade Load Monitor detects sudden changes in speed and/or track slippage and shifts down to keep the load under power. These tap into information coming from an additional GPS sensor. The D5’s new technology features include Blade Load Monitor and Traction Control. You can program the values you want on the screen and even let go of the joystick and the machine will continue on the slope parameters set on the screen. With Slope Assist, your fore-aft tilt and side-to-side blade angle show up on a monitor in the cab. It basically does the same thing as the old, gravity-based angle indicator gauges except you don’t have to eyeball the gauge on the back of the blade. Slope Assist automatically maintains a blade slope setting when you don’t have a GPS signal or laser to guide you. These small efficiencies, over the course of a day also add up to improved productivity.
