It comes as a regular bulldozer and a Carrydozer like the previous model. The current D11T was introduced in early 2008 and is also 850 hp (630 kW). According to Caterpillar, by the year 2000 over 3,000 D11s had been produced at their plant in East Peoria. The Carrydozer's weight is just over 120 short tons (110 t) at 248,600 pounds (112,800 kg). Both D11R and D11R CD received a new Caterpillar 3508B EUI electronically controlled unit injector diesel engine with electronic controls at 915 gross hp (682 kW). The Carrydozer had the structure strengthened considerably for the extra weight and the much bigger blade that it carried up front, also, the ripper was fitted with an additional counterweight block. Komatsu developed a lengthened Superdozer undercarriage with two additional rollers per side to reduce wear, a step that Caterpillar avoided for their Carrydozer machines. These higher undercarriage costs must be considered when opting for a Carrydozer version. The increased weight on the undercarriage means also higher contact pressure between rollers and track links, which can increase wear significantly. The deeper curvature of the Carrydozer/Superdozer blades literally carry the dirt moved, and the weight of the load increases pressure on the undercarriage and is thereby increasing the traction of the bulldozer. This blade design was introduced by Komatsu on their D575 A-2 dozers in 1995 as the Superdozer version. The Carrydozer version has a special blade with a curvature that allowed 57 cy ( 43.6 m³) to be pushed. The finger tip controls (FTC) allowed the D11R to be steered with small fingertip clutches on the left hand side. Other improvements made to the D11R were fingertip controls and electronic clutch and brakes. Both were 770 hp (570 kW) and that would be increased to 850 hp (630 kW) later in 1997. The D11R and D11R Carrydozer were introduced in Las Vegas, Nevada, at MINExpo International in 1996. This would become known as the D11N Impact Ripper. In 1987 a hydraulically powered impact ripper was added to the D11N which raised the weight up to 225,950 lb (102,490 kg). The D11N's improvements made it over 10 percent more productive than the D10. This increased the blade capacity to 45 cu yd (34 m 3). The U blade was just under 21 feet (6.4 m) long and 7 feet (2.1 m) high. The D11N had some major improvements over the D10: it includes a bigger track and blade, and a longer track by 21 inches (0.53 m). The D11N was introduced in February 1986 to replace the D10. Primarily designed as a bulldozer, it is also used for push-loading scrapers, and ripping rock overburden. in East Peoria, Illinois, and mainly used in the mining industry.
