- Total power, kW - 173
- Dump volume, m3 - 5.6
Three models of CASE bulldozers ranging from 13.5 to 24 tons are supplied to Russia. All machines are manufactured in Brazil. At the same time, the flagship of the line is the 2050M, one of the main advantages of which is considered to be high tractive effort (360 kN). All CASE bulldozers are equipped with FPT engines manufactured by the CNH Industrial group of companies. The diesel volume of the 2050M model is 6.7 liters, while a torque of more than 1,000 Nm is developed in a wide operating range from 1,100 to 1,740 rpm.
The machines are equipped with a Bosh Rexroth hydrostatic transmission, which provides continuously variable speed changes and constantly high torque on the track. The new V-shaped cooling system allows airflow to be directed effectively to each radiator individually, since none of them is blocked by another. As standard, CASE bulldozers are equipped with a reversible fan with an increased number of radiator fins.
The basic delivery package for CASE bulldozers includes an extended XLT chassis, which gives the equipment additional stability and, therefore, greater precision in the work performed. As an option, CASE bulldozers can be equipped with a CELT (CASE Extended Life Track) chassis type, which includes a solid sprocket, open shoes, and double bushings, resulting in uniform wear and increased service life of this component.

- Engine power, kW — 155
- Dump volume, m3 - 5.6
A wide range of Komatsu bulldozers (from 8 to 72 tons) are available to Russian consumers, but according to dealers, the D65EX-16 model is in greatest demand.
It is worth noting that the design of Komatsu machines uses components of its own production, including the engine and transmission. They are produced at the company's sites in Japan. The engine is one of the most powerful in its class: it is capable of delivering up to 155 kW, with a displacement of 8.3 liters.
The equipment of the D65EX-16 bulldozers sold in the Russian Federation includes a three-post ripper, a double reinforced radiator grille, a hydraulically driven radiator fan, an improved fuel filtration system, air conditioning, a color monitor, and the Komtrax remote monitoring system. The HSS hydrostatic steering system provides constant drive to both tracks without interruption of torque. The width of the track shoes included in the basic kit is 510 mm.
Along with the standard version of the dozer, Komatsu offers temperature specifications for operation at -30 and -40 degrees. In the first case, the equipment is equipped with more powerful batteries, special rollers and a final drive for low temperatures. In the second, a liquid preheater, additional sealing of hydraulic cylinders, a starter and a generator of increased power are added. The cabin is also double glazed.
One of the main features of the model is the SIGMA blade with a volume of 5.6 m3, which allows you to move soil at higher speeds and helps reduce fuel consumption. But the manufacturer has also provided other versions of dumps: hemispherical (5.6 m3), straight (3.89 m3) or PAT (4.25 m3). An auxiliary cabin heater, an electric fuel filter heater, a liquid preheater, and a Topcon automatic leveling system are available as options.
Domestic and foreign manufacturers of bulldozers
Renting a bulldozer allows you to optimize many types of work:
— digging pits for laying the foundation; — digging trenches; — quarry development; — work in areas with unstable surfaces; — clearing the territory; — marking the construction site; — leveling the ground surface; — construction of embankments and dams; — road planning.
And this is just the main list of earthworks where it would be advisable to rent a bulldozer, which is offered by the Crane-Master company. The advantages of renting a bulldozer include low prices and additional bonuses provided by the company. Thus, the cost of renting a bulldozer already includes refueling and the work of a professional, experienced operator.
Bulldozers of domestic and foreign companies
1. Bulldozers Caterpillar Inc. Caterpillar bulldozers are actively used for road construction. They are mainly designed for leveling surfaces for transport lines, residential construction sites and commercial sites. The bulldozer lineup includes the D-series (Caterpillar D4-D11) and the Caterpillar 60, one of the first bulldozers released under this brand.
Caterpillar bulldozers are reliable, multifunctional, environmentally friendly and profitable. The products of this brand are supplied to almost 200 countries around the world. To cope with such sales volume, Caterpillar maintains 109 factories and has an extensive dealer network. There are representative offices in Russia (Moscow, Leningrad region, Novosibirsk).
Addresses of distributors and car dealerships in Moscow and St. Petersburg, specializing in Caterpillar equipment, can be found on the website of the representative offices. By the way, in August 2008 the 35th anniversary of the Moscow representative office of Caterpillar was celebrated.
2. Komatsu bulldozers. Currently, Komatsu equipment is used all over the world for road construction and other works. The name of the product gives away its homeland. “Made in Japan,” we say, in one phrase immediately denoting the country of origin and the quality of the equipment it produces. The Komatsu Group company was founded in Japan in 1921. Who would have thought that the modest construction workshop of Meitaro Takeyuchi would grow into a network of about 200 large companies.
The Komatsu brand includes backhoe loaders, motor graders, mobile crushers, dump trucks and bulldozers. Komatsu bulldozers are a worthy competitor to the machines of the world leader Caterpillar. Unlike the latter, Komatsu exhibits not only crawler bulldozers (for example, models D475A-5, D155A-5), but also swamp dozers (D85PX-15, D39PX-22, D37PX-22) and wheeled bulldozers (WD900-3, WD600 -3, etc.).
3. ChTZ bulldozers . This is a multifunctional technique: bulldozers of the DET model can be used by construction companies for leveling soil of any hardness, filling holes, ditches, as well as for agricultural purposes and for cleaning city areas. The presence of replaceable devices in the DET-250, the dismantling of which does not require the participation of additional equipment, in particular lifting machines, as well as moving parts (rotary blade), the ability to use bulldozers together with other equipment (plough-brush, drilling) ensures their versatility.
The maximum transport speed of these machines reaches 25 km/h, which allows the bulldozer to be used on several sites at once, not very far from each other. The dimensions of the series equipment make it possible to carry out work even in densely built-up areas of the city. The basic configuration can be expanded at the buyer’s request (for example, a rotary blade can be installed upon request).

Chinese bulldozers face protective duties in Russia
The Department for the Protection of the Internal Market of the EEC has resumed an anti-dumping investigation against bulldozers supplied from China, as follows from the official notification (available from Gazeta.Ru) of the department. The initiator of this investigation was the Russian competitors of Chinese bulldozers: the enterprises ChTZ-UralTrak, DST-Ural, PC Promtractor and Chelyabinsk Industrial Tractor Plant.
The object of investigation is Chinese bulldozers with fixed and rotary blades with a capacity of up to 250 horsepower (the most popular in sales). The applicants claim that in the period from January 1, 2019 to March 31, 2020, bulldozers from China “were supplied to the territory of the EAEU at dumping prices, that is, below the normal cost in the domestic market of the PRC.”
“The normal cost was determined on the basis of marketing research on the prices of goods from a number of manufacturing companies in the domestic market of the PRC, taking into account the necessary adjustments,” the applicant’s position is stated in the notification of the EEC Domestic Market Protection Department.
In turn, Russian factories calculated the export price of Chinese bulldozers based on the statistical customs data at their disposal on the volume of imports of crawler bulldozers. The Russian side claims that the dumping margin (the difference between the price in China and Russia) on supplies of crawler bulldozers to the union from the PRC during the specified period amounted to 25%.
In this case, a dumping margin of no more than 2% is considered acceptable.
This is not the first anti-dumping investigation by the EEC against Chinese bulldozers. For the first time, Russian tractor factories complained about imports from China in 2014. At that time, domestic manufacturers actually controlled the Russian bulldozer market with a total share of 84%; now the market share of the applicants is already slightly more than 50%. In 2020, the investigation was completed, and the EEC increased customs duties for light Chinese bulldozers to 11-44%, depending on specific companies.
Protective duties were introduced for 5 years; in fact, the new investigation is precisely due to the fact that now the Chinese can again freely supply their equipment at low prices to the EAEU market. The operative part of the decision stated that Russian companies, under pressure from Chinese dumping, could not trade their products without the risk of not covering the costs of their production. In 2011-2013, due to the actions of Chinese importers, the profitability of the production of domestic bulldozers fell by 25%, the EEC reported.
Representatives of Russian companies did not answer questions from Gazeta.Ru about the reasons for the new investigation and the situation on the market. Chinese manufacturers were also unable to promptly comment on the likely risks in connection with the new anti-dumping investigation.
Despite various barriers, Chinese special equipment is increasingly in demand among Russian companies,
a source in one of the large companies importing Chinese bulldozers told Gazeta.Ru.
“I can say that in the north people prefer to take Chinese Shehwa and Shantui bulldozers - they break down less, older machines are less demanding on the quality of diesel fuel, the new ones have more complex equipment, it’s better not to waste fuel there. Our equipment is purchased by those who are ready to immediately purchase spare parts and have repair facilities - if this is the operating model they choose. But where the climate is very cold, there is no time for repairs, so they prefer to hire Chinese or Japanese,” said an interlocutor at a trading company.
There is a high probability that the EEC will recognize the claims of domestic companies against Chinese manufacturers of special equipment as justified, says lawyer and human rights activist Sergei Ifanov. According to the expert, Russia quite often becomes involved in similar anti-dumping investigations as part of its membership in the World Trade Organization (WTO). And very often foreigners manage to protect their market from Russian competitive goods.
Ifanov cited the example of the story of Russian tires in Brazil. In 2013, Brazilian tire manufacturers complained to the WTO that allegedly Russian truck and bus tires were supplied at dumping prices. In 2020, the WTO Commission sided with local manufacturers, as a result, a customs duty was set at 72.4% for Russian tires, which actually became a barrier.
“I believe that Russians have the right to protect their own market and domestic producers, as other countries do. At the same time, regulatory authorities must act carefully; at least minimal competition is needed for our companies to invest in production development,” concluded Ifanov.
