What is the output of bulldozer in volume/hrs? Most wheel dozers are equipped with torque converters and power-shift transmissions, some are direct drive. This machine is sometimes referred to as a tire bulldozer and is normally larger than a crawler bulldozer. Larger crawlers have rippers that help with crushing and clearing dense terrain. What is the difference between a wheel Dozer and a crawler bulldozer? This increased the blade capacity to 45 cu yd (34 m3). 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). Lift and push the loose stump and grind it down or chop it up to dispose of it. Use the bulldozer to push the stump until the roots pull out of the ground. Dig a trench that’s three feet wide and eight feet deep on all sides of it. Bulldozers have transmission systems designed to take advantage of the track system and provide excellent tractive force.Ī bulldozer can remove stumps. The tracks give them excellent ground-holding capability and mobility through very rough terrain. Typically, bulldozers are large and powerful tracked heavy equipment. New model pricing starts at around $2.2 million.

Rippers are used to break up land to allow agriculture to grow or break down rock and earth to be moved.ĬAT D11 Price: Older used models go for as little as $85,000 with no add-ons but can cost $1 million or more for more recent used models, depending on features. Total Operating Weight* (with SU Blade and noted ripper)Ī ripper is the extended attachment located at the rear of the bulldozer that resembles a claw. Maximum Clearance Raised – Under Tip, Pinned in Bottom Hole Ripper – Single Shank Maximum penetration force * (shank vertical) Some dozers, such as the Komatsu 575, exceed the weight and horsepower specifications of a large dozer. Production dozers Small – less than 20,000 pounds, 75 – 125 hp. The D9 weighs about 50 tons and has power of about 410 horsepower and drawbar pull of 71.6 metric tons. Bulldozer ModelĬaterpillar D9 is a heavy tracked-type tractor, commonly refer to as a bulldozer. You can expect an average bulldozer weight to be about 17,400 pounds (7,893 kg) for a small dozer….7 Example Bulldozer Weights. 4 What is the difference between a wheel Dozer and a crawler bulldozer?.1 How much weight can a bulldozer lift?.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 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.
