Overview The new Cat ® D2 delivers superior performance and the broadest choice of technology features to help you get the most from your dozer.
What do you need to know about the new cat D2? in) four-cylinder natural aspirated diesel engine with 95.0 mm (3.74 in) of the cylinder bore and 127.0 mm (5 in) of the piston stroke.The Cat D2 dozer used a mechanical clutches steering, 12-inch tracks, and an open operator station. What kind of engine does a D2 caterpillar Dozer have? Ortiz has recently added a new D11T to the fleet and says the price came out at $2.2 million. Since 2008, the biggest Cat is the D11T, weighing some 230,000 pounds. (23 to 30 L) of diesel each hour, with larger graders consuming several times more than that. Medium-sized graders push and shove and burn their way through 6 or 8 gal. Fuel consumption of larger dozers like the D11 can be five times that much. (24.7 L) of diesel an hour when operating under moderate conditions. It superseded the D10 as the biggest crawler dozer in the Cat product range. Under 105 hp, the Cat® small dozers are designed to optimize speed, transportability, maneuverability, versatility and finish grading accuracy. What is the smallest bulldozer that Caterpillar makes? Inline-4 cyl diesel engine: Caterpillar D311 3.6 L (220 cu in) Caterpillar D3400 4.1 L (250 cu in) Length with SU-Blade** – No rear attachment For machine with ripper, add 554 kg (1,222 lb).Ĭrawler Dozers. National Group received the first new D11 off the production line, delivered by Hastings Deering in December 2019.For machine with ripper, add 554 kg (1,222 lb). When backed by the Caterpillar dealer network’s industry leading parts availability and after sales support, the new D11 is sure to establish itself as a stalwart in the industry.įurther improvements are difficult to fathom at this time, but you can be assured the team at Caterpillar are already working on it. The improved geometry of the blade tip circuit also gives the new D11 increased range of motion enabling the ability to “carry” more in your blade, further improving productivity when measured by the hour, or by the litre of fuel burnt. Roy noted that despite the increased mass, the new D11 seemed more nimble and maneuverable when working in difficult situations such as pushing shot rock. Variable displacement piston hydraulic pumps constantly vary their output to meet the needs of the task or operation meaning less wastage and improved sensitivity when its needed for finer operations.Īn overall increase in weight also makes the new D11 more stable and improves traction. One key factor in the improved fuel efficiency of the D11 is the load sensing hydraulics which improve efficiency and reduce energy loss. Roy also noted the reduction in sound levels heard at the Operator’s station as a vast improvement, although he did have an appreciation for the old 3508 engine in his previous D11R with its rhythmic V8 song and whistling turbos. With the capacity to tailor the performance of the machine and the sensitivity of functions more so than with previous variants, the operator can set up automatic functions and maintain high quality work produced with minimal effort.

Having spent time on the D11N, D11R and D11T models, Roy gave us his insights into the evolution of Caterpillar’s largest and most imposing track type tractor.Īs you’d expect, comfort is a big issue for all Operators, and Roy was not disappointed with the D11.Įrgonomically, Roy believed the new D11 was an improvement on the former T series noting the cab layout, function of controls and touch screen monitor as key elements in the reduction of operator fatigue and improved productivity. Seasoned Operator Trainer Assessor with National Group, Roy Bamford was one of the first Operators in Australia to get in the seat and draw some comparisons to the previous models.

Changes in engine and transmission software and updated componentry for example, boast fuel savings of up to 8% which is huge when you’re talking the volumes of fuel consumed in a bulk push application on a double shift roster.
