Rippers can come singly (single shank) or in groups of two or more (multi shank rippers). The D11 is most commonly found in use in large scale forestry, mining, and quarry operations.ĭ11s can be adapted for agricultural and rock ripping by fitting a ripper, a long claw-like device on the back of the tractor. For example, they are often used in quarries. The Caterpillar D11s were designed for massive dozing and pushloading of scrapers on mine and construction sites around the world.ĭ11s are primarily used for moving large quantities of material (dirt, rock, aggregate, etc.) short distances in relatively confined places.
As with the D11R the D11T Carrydozer can push 57.9 yards while the regular D11T can push 45 yards of earth. This 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. According to Caterpillar by the year 2000 over 3,000 D11s have rolled out of their plant in East Peoria. The Carrydozer versions weight is just a shade under 120 tons at 239,550pounds. Both D11Rs got a new 3508B EUI diesel engine with electronic controls at 915 gross hp. The 'Carrydozer' had the structure strengthened considerably for the extra weight and much bigger blade that it carried up front. The Carrydozer version has a special blade with a curvature that allowed 57 yards to be pushed. The FTC allowed the D11R to be steered with a single lever (joystick)on the left hand side. Other improvements made to the D11R were Fingertip Controls and Electronic Clutch and Brakes. Both were 770 hp and that would be increased to 850 hp. The D11R and D11R Carrydozer were introduced at the Las Vegas at Minexpo 1996. This would be come known as the D11N Impact Ripper. In 1987 an hydraulically powered impact ripper was added to the D11N which raised the weight up to 225,950 lbs. The D11Ns improvements made it over 10 percent more productive then the D10. It was 770 hp powered by a 2,105 cubic inch 3508 V-8. This upped the blade capacity to 45 yards. The U blade was just under 21 feet long and 7-7 inches high. The D11N had some major improvements over the D10, it includes a bigger track and blade,a longer track by 21 inches. The D11N which was introduced in February 1986 to replace the D10. Primarily designed as a Bulldozer, but also used for push loading scrapers, and ripping rock overburden.
