D 11 DOZER SOFTWARE
D 11 DOZER SERIES

Cab and engine bay doors open on both sides and access steps swing down into position. The CD version weighs in at a whopping 7.7kg and the U-blade model is 7.1kg. These big models stand at approximately 7.7вЂі at the top of the ROPS canopy, this impressive model reaches 18.1вЂі long and 11вЂі wide. Two models have been produced, one with a U-blade and single shank ripper attachment, the other is a Carrydozer with Multi-shank ripper version which we have here for a model review.

Put into context, a family diesel car achieving 50mpg and traveling 10,000 miles per annum will go for 60 years on this level of fuel saved!Д¬lassic Construction Models (CCM) have just released the much anticipated D11 in 1:24 scale to add to their collection of die-cast replicas. Cat claim this new dozer can save an average 54,553litres (12,000 gallons) of fuel per year per machine. Its new load sensing hydraulics, frame, mounting pins and bigger engine oil capacity lowered maintenance cost by 5%, resulting in an improvement to lower overall cost/bank cubic metre of up to 6%. This new ultra-class dozer is simply known as the D11, and has increased productivity, efficiency, and lowered fuel burn by nearly 8%. The mighty D11T was then introduced in early 2008, and after a ten year reign as one of the worldвЂ™s top mining and bulk earthworks dozers, in November 2018 the best just got better, when Caterpillar introduced the Next-Generation D11. The big Carrydozer modelsвЂ™ weight was just over 108.8 tonnes and by the year 2000, over 3,000 D11s had been produced at their plant in East Peoria. The D11R and D11R Carrydozer were then introduced in Las Vegas, Nevada, at MINExpo International in 1996, with innovations such as fingertip controls and electronic clutch and brakes.

National Group received the first new D11 off the production line, delivered by Hastings Deering in December 2019.Caterpillar have been producing the mighty D11 series of dozers since February 1986, when the 92.7tonne, D11N was introduced with a 34 m3 blade and 770hp engine to replace the D10 as CaterpillarвЂ™s top of the range ultra-class dozer. When backed by the Caterpillar dealer networkвЂ™s industry leading parts availability and after sales support, the new D11 is sure to establish itself as a stalwart in the industry.ДЇurther 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 вЂњcarryвЂќ 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.ДЄn 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 OperatorвЂ™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 CaterpillarвЂ™s largest and most imposing track type tractor.ДЄs youвЂ™d expect, comfort is a big issue for all Operators, and Roy was not disappointed with the D11.Д®rgonomically, 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 youвЂ™re talking the volumes of fuel consumed in a bulk push application on a double shift roster.
