Cat estimates that in the proper application, a CarryDozer will be 10–15% more productive than a standard D11T with a U-shaped blade. The CD’s frame and blade are built specifically for carrying-not pushing, as with conventional dozers-material long distances, and the CD’s front end is built to handle the higher frame loads generated by the machine’s 22-ft-wide, 9-ft-high blade, designed to carry up to 57 yd3 of material. The D11T CarryDozer (CD), a specialized model used mostly in bulk earthmoving applications, has an operating weight of 249,122 lb (113,000 kg). A slope and stability monitor feature available on the D10T and D11T displays machine slope and side-slope indications on the Advisor Monitoring System screen. Improved visibility features available on the D9T, D10T and D11T provide cameras and mirrors to increase operator visibility around the machine.

This setup is currently available on the D11T and will become available on the D10T in late 2010.

Other available features in the T series dozers include a hydraulically powered access ladder, along with a rear platform and larger fuel tank to provide easier and safer access to the cab and rear areas of the machine. An optional AutoCarry feature on the D10T provides automatic blade control while the tractor is carrying a load, enabling higher productivity in situations in which the carry distance is more than 100 ft. Other enhancements included an Advisor Monitoring System that provides onboard diagnostics, displays key machine operating information, and allows the operator to set and adjust various features including blade response, blade float, auto blade pitch and spread rate.

In the T series, Cat streamlined the cab layout by replacing some control levers with electronic switches, and further improved operator visibility by making the cab windows larger, tapering the hood and narrowing the single-shank ripper carriage.

Among the benefits listed by Cat for high drive are improved productivity, a modular design that allows rapid changeout of drive train components that can be preassembled and tested before installation, better operator efficiency due to improved visibility and ride comfort, and quick disassembly of major tractor components for easier transport by truck or rail. The D10T retained the elevated final drive system, as did the T version of the D11, which was unveiled in October 2007, and the company has shown no indication that it plans to move away from this design for its large dozers in the foreseeable future. The current D10T, introduced in 2004, is driven by a Cat 12-cylinder C27 diesel, with power applied to the tracks through an electronically controlled powershift transmission. Komatsu also offers the D575A-3SD, a 336,420-lb, 1,150-hp behemoth fitted with a 90-yd3 blade, compared with the D475A-5SD’s 890 hp and 58.9-yd3 blade, and recently introduced a successor to the D375A-5E0.Ĭat’s Elevated Drive Endures Cat has evolved the original D10 design through a series of model upgrades including the D10N in 1986, followed by the D10R in the mid-1990s. Liebherr has made interesting advances in bulldozer drive technology, offering the world’s largest hydrostatically driven crawler tractor (more on this in next month’s issue, highlighting German mining technology), and Deere sells a large number of smaller machines, but the Cat D10T, D11T and D9T, along with Komatsu’s D375A-5E0 and D475A-5, along with the rarer Cat D11T CarryDozer or Komatsu D475A-5SD Super Dozer, are the machines most often seen at mine sites. Today, the large-dozer market is dominated by Cat-having sold more than 100,000 of the high drive machines worldwide-and Komatsu. In particular, the last four decades have seen a steady escalation in mining-class dozer power and technology, starting with the introduction of 500-plus-horsepower crawlers from Allis Chalmers in the late 1960s, followed by Komatsu’s 620-hp D455A in the mid-1970s, and Caterpillar’s introduction of the D10 in 1978, the first model fitted with Cat’s elevated-sprocket “high drive” system.

Productivity is the primary driver pushing dozer performance, but safety, reliability and operator comfort have increasing influence in steering dozer design trendsįor a machine that, not too long ago, featured cable-operated blade controls, an open-air operator’s station sprouting thickets of levers and clutch pedals, and not much else but brute power and noise, the crawler bulldozer has come a long way from its 1920s origins as a modified farm tractor.
