The word "bulldozer" came into use at the end of the XIX century. At first, this was the name of any mechanism that is capable of moving a huge mass. Only in 1923 the first self-propelled machine based on a tractor with a front bucket appeared. This was the first bulldozer in the world. Over time, various modifications of these bulky and noisy cars appeared. The world of technology is constantly evolving, and a short review presents the largest bulldozers in the world.
The largest bulldozers in the world:
10
CHETRA T40. USSR-Russia
Let's start with the model that was assembled at Promtractor OJSC. Now, due to difficulties with financing, the project is almost closed, and new copies are not collected.
A fairly productive bulldozer with a blade volume of 21 cubic meters. The total mass of the T40 is a little more than 65 tons, and the power of the Cummins QSK19-C650 engine is 590 hp. A U-shaped blade was installed on the model, which significantly increases productivity and makes it possible to work on slopes.
The driver’s cab was equipped with a heating system, since the tractor is also operated in the Far North. To facilitate control, a hydraulic system is installed on it and the chassis is improved, when compared with previous models.

CATERPILLAR D10T. USA
The first copy of the D-series was released back in 1978. At that time it was the most powerful bulldozer in the world. The T series has replaced the N and R models. Over many years of operation, it has proven its high productivity and efficiency.
D10T weighs 66 tons. A powerful engine of 671 hp is installed on it. The length together with all attached units reaches 7.7 m, and a height of 4 m the engine allows you to “disperse” the digger to 12.5 km / h. When working in steep quarries, an additional safety system is installed on the chassis so that the machine does not roll over during operation.
These models are available now. The designers improved the technical characteristics of the bulldozer by adding the number “2” to the name D10T.
By the way, at TheBiggest.ru you can watch, and also learn a lot of interesting things about the largest engines in the world.

KOMATSU D375A-6. Japan
Among the counterparts of earthmoving equipment, this model of the Japanese manufacturer is perhaps the fastest. D375A-6 can reach speeds of up to 15.8 km / h.
It has an “SAA6D170E-5” turbocharged engine with a cooling system. Engine power 646 hp The machine meets all environmental requirements and safety criteria. The total weight of the bulldozer is 72 tons.
The universal model allows you to operate it in any conditions, providing high performance. Two types of blade are used, with a volume of 18.5 and 20 cubic meters. The last instance came off the assembly line in 2009, but the D375A-6 continues to operate today.

Fiat-Allis FD50. Italy-USA
Italian designers perfected the 41B Dozer, and the world saw a new powerful tracked tractor with a blade blade. The first model came into operation in 1974.
In the development of the new machine was attended by American experts. The result was a bulldozer with high technical characteristics. The Cummins VT28-C engine with a capacity of 600 hp was installed on the new model. The total weight of the FD50 is 80 tons.
Financial difficulties led to the closure of the project. The last time the plant gathered this handsome man in 1989. But, despite this, these machines continue to work today in quarries and on construction sites.

Promtractor T-50.01. USSR-Russia
In 1980, a caterpillar career bulldozer came off the assembly line of the Cheboksary plant. The model weighs 93.5 tons in full gear, and the engine power is 750 hp.
The designers installed a U-shaped dump on the machine, which allows the T-50.01 to be operated in difficult career conditions. The machine can deepen its main working tool into the ground by 1 m. The blade can move 28 cubic meters of land.
In modern times, the model was modernized, so now it works easily in any conditions. A machine is capable of not only moving the earth, but also working in rocky and frozen soils.

ChTZ T-800. Russia
For the first time, Soviet designers of the legendary Chelyabinsk Tractor Plant introduced the T-800 in 1983. At that time, in size and weight, the Soviet bulldozer occupied the 2nd place in the world.
The Soviet machine, leaving the assembly line, immediately began work on the construction of the South Ural nuclear power plant. Immediately established itself as a hard worker. On it, unlike foreign analogues, a 6-cylinder engine with a capacity of 820 hp is installed. The machine weighs 106 tons.
Technical characteristics and power allow the T-800 to operate in the Far North, where it easily copes with permafrost. Use the giant and the construction of large facilities.

KOMATSU D475A-5SD. Japan
Experts note that this is the best instance in the line of earthmoving machines in the ratio of power and dimensions. Japanese experts improved the chassis on this model, and also protected it from external influences.
This colossus weighs 108 tons, and the dump volume is 34.4 cubic meters. The length of the machine is 11.5 m and the height is 4.6 m. The engine capacity is 890 hp, which allows you to cope with complex tasks. It speeds up to 14 km / h.
Thanks to technical improvements, this bulldozer can work in extreme conditions. Upon delivery to the place of operation, some units are assembled into blocks for convenient transportation.

CATERPILLAR D11T CD. USA
The equipment of this company is the leader in terms of sales and models available on the market. Caterpillar is one of the market leaders in agricultural machinery as well as in industry. In addition, we on thebiggest.ru pages already mentioned the corporation in articles about the largest mining trucks and the most powerful trucks in the world.
High-performance T-line bulldozers have been developed for open pit mining.
The weight of the “D11T” is 113 tons, and the engine power is 950 hp. ACERT system is installed on engines, which allows saving fuel and also reduces harmful emissions into the atmosphere. The driver works in a comfortable ergonomic cab.
The height of the bulldozer is slightly more than 4 m, and the length with a cultivator reaches 9.26 m. With such dimensions and weight, this is a fairly maneuverable and fast machine. It moves at a speed of 7.5 km / h, but it goes back faster - 8.7 km / h. But speed in such models is not the main thing.

KOMATSU D575A-3SD. Japan
The largest of the currently working bulldozers assembled by Japanese designers in the late 70s of the twentieth century. For the first time, the world saw a super giant at the Texas World Tech Show in 1981.
The height is 5 m, and the length of the machine is 12.5 m. With such dimensions, the D575A weighs 153 tons. It moves with the help of a turbocharged engine with a power of 1,167 hp. The dump of a modified specimen is capable of moving 96 cubic meters of land. The cab meets the requirements of operator comfort and safety.
It is used only in open pits, since its delivery to the place of work is a complex engineering operation. Throughout history, 88 cars were produced that the United States and Australia bought.

ACCO Dozer. Italy
The largest instance in the history of bulldozer construction was developed and assembled by order of Muammar Gaddafi. The ruler of Libya had ambitious plans. The machine was intended for construction work, which the Libyan leader planned to carry out in his country.
The order was received by the Italian company Umberto Acco, whose designers presented the world a prototype in 1980. The super giant weighs 183 tons, and the power of its two engines totaled 1,300 hp. The blade height was 3 m and the record width was 7 m.
Sanctions were imposed against Libya, because of which ACCO Dozer did not begin construction work. There is no longer a company that has assembled the largest bulldozer. It was never disposed of, and it still stands on one of the viewing platforms.

Conclusion
Our top 10 largest bulldozers are finished. Designers do not stand still, constantly changing the technical characteristics of bulldozers and increasing their dimensions. Earth-moving machinery that has served its age is being scrapped, and new technological and maneuverable models take its place. Note that the bulldozer has its own monument. In 2007, the legendary Soviet S-100 entered the pedestal, which was the main vehicle in the development of the vast expanses of the Soviet Union.
