Bulldozers belong to the category of self-propelled equipment, with caterpillars designed for digging soil and equipped with special body kits. For the first time such machines appeared in the 21st year of the last century. Early copies were designed on the basis of a standard tractor and differed from the progenitor only in the presence of body kits for digging work.
The mass production of machines for digging the earth was debugged by the 31st year of the 20th century. The architecture of the device remained the same, that is, the standard tractor received a system of additional equipment. Technological innovations have made it possible to improve the bulldozer by turning it into an earth-moving combine.

In the Russian Federation, this technique has become widespread in many industrial areas:
A company from China offers the buyer a choice of high power models. The company from the city of Shantui originates in the 80th year of the last century and since then has expanded exponentially. The company enlisted the support of the state, because the equipment produced by the plant is used for the needs of the PRC. Before the founding of the plant of the same name, the country's leadership bought bulldozers abroad, because domestic production did not produce models of the required power (more than 180 hp). At the beginning of production, the company was assisted by specialists from Japan, who transferred working technologies and quality standards to their Chinese colleagues.
The first copy, under the name Ty-220, went to the aid of miners. The model has worked for almost 30 years and over 20 thousand working hours. During the above period, the machine requested a total of 3 maintenance. With such length of service, the number of overhauls is negligible, so the equipment from the Chinese factory has gained fame as reliable working machines. Under the wing of the company, the following models of bulldozers are produced:
Review:
“I use a machine from the Sd52 model range, since this particular copy is provided by a construction company. My job is to prepare the site, dig the foundation for the construction of apartment buildings. The bulldozer shows excellent results and strong reliability, in comparison with other machines of this category that I have worked with before. For 1.5 years of operation, maintenance was not required, in addition, the model shows its best side even when working with problematic soil. I recommend Shantui bulldozers!”
The company is based in the USA and occupies a leading position in the global market for special equipment designed for construction, earthmoving and related work. The company produces bulldozers with a running gear on a caterpillar. The assortment includes specimens of all power categories: from weak to high-power models.
Bulldozers of the company are equipped with an engine from the same company. Cat engines are famous for their thoughtful waste gas distribution mechanics, as well as an advanced machine electrical control system and calculation of the dose of fuel supply.In addition, the architecture of the engine implies the presence of adjacent cooling systems, which significantly increases the life of the bulldozer without repair.
Automatic control mechanisms are integrated into the machine to achieve the greatest accuracy during work. The on-board computer is equipped with a tracking system connected to the satellite, which allows you to record the operations carried out on the bulldozer (up to hours of operation of the equipment) and collect data on errors that occurred during the session. The collected data is sent to the host computer in the form of a report. Such a system allows you to control working sessions down to the details.
The working cabin is designed based on modern safety requirements and the competent use of working space. The state of the machine and the data necessary for operation are displayed on the on-board computer screen. The seats meet modern requirements for comfort, and there is also the possibility of fine adjustment of the position of the operator. This approach allows you to achieve the greatest visibility when performing transactions. Special gaskets are laid between the cab and the body, which reduce vibrations and extraneous sounds inside the cabin to a minimum. This is necessary to save the operator from unnecessary irritants.
Review:
“I am the founder of a construction organization and I faced the question of buying high-quality equipment for digging foundation pits. First, our company bought several bulldozers of a little-known brand. The equipment served with varying success for about a year, after which serious problems began with the stability of work.Then it was decided to purchase bulldozers from a well-known manufacturer. The choice fell on Kat and fully justified itself! The bulldozers of this brand show excellent results in terms of stability, and the operators give only positive feedback about their work. During the entire period of ownership, there were no problems, the machines did not require repairs, and the electrical equipment works stably. Would recommend to anyone looking for quality bulldozers!”
Komatsu was founded in Japan in the 21st year of the 20th century. The company is considered one of the largest in its native country. It specializes in the production of equipment with a caterpillar undercarriage system. Instances from Komatsu differ in a number of unique developments. The design of the machine body is arranged in a special way: the hood is angled so that the operator has a large view of the site. Such a solution allows you to significantly increase the productivity of operations in practice.
The gearbox is equipped with smooth running mechanisms. The system includes hydraulic elements, which allows shifting with increased convenience and smoothness. In addition, such mechanics provide the employee with a choice between manual control or automatic control, indicating the upper limit of the speed limit. The hydraulic transmission system does not need auxiliary braking elements, this gives flexibility in control. The checkpoint is controlled electronically, so all related operations occur automatically.
Increased convenience in bucket operations. Canopy mechanisms distribute pressure evenly and allow you to achieve the greatest balance under loads.The worker controls the bucket with a joystick, there is the ability to switch between working angles.
The load on the technical pads and the operator is minimized. Automatic mechanics brings even high loads to balance, which makes it possible to increase the overall efficiency of operations and reduce fuel consumption.
The salon meets modern standards of comfort, is equipped with protection against extraneous noise, shock and working vibrations. A similar effect is achieved with the help of technical gaskets.
The company provides the possibility of ordering specific nozzles. The buyer can place an order for buckets of any shapes, sizes and formats, just fill out the form and place an order with the design requirement.
Review:
“I am a self-employed bulldozer operator. For all the practice of the operator, I had to change from a dozen different machines, so I can form an informed opinion about the advantages and disadvantages of various models. Bulldozers from Komatsu are characterized by increased comfort regarding work and being in the work chair. The work of engineers is noticeable, because the viewing angle is as convenient as possible in almost any position. Gear control is implemented with all the conveniences, the gearbox is easy to get used to, and shifting gears is a pleasure.”
The Chelyabinsk enterprise for the production of tractor equipment is considered one of the largest industries in the Russian Federation, whose specialization is the manufacture of special equipment of all categories. The enterprise originates in the 33rd year of the last century.
The choice of the buyer presents a series of bulldozers:
The buyer is provided with a wide choice of machines of various specifications and prices. It is worth noting that the purchase of Chelyabinsk bulldozers is more affordable than foreign ones, because not only the price of equipment, but also the cost of delivery is included in the payment, and if the product is domestic, then the delivery is several times cheaper.
Review:
“My company is connected with earthworks, so the need for special equipment is obvious. A device from a Chelyabinsk manufacturer entered the service of the company, because the cost of a domestic bulldozer is significantly lower than that of a foreign one. In work, the Chelyabinsk bulldozer shows strong results. There were breakdowns, but spare parts for domestic devices are also available, which greatly simplifies maintenance. I recommend bulldozers from the Chelyabinsk manufacturer to anyone who is looking for a strong machine for adequate money!”
Company for the production of special-purpose equipment, based in Germany, originates in 1949 of the 20th century. The company specializes in the production of bulldozers of medium and high gravity categories. Production consists in the manufacture of a single line of machines, consisting of 5 copies. The company offers the buyer a set of unique features of its products.
The engine uses a unique architecture that allows you to balance power and load to achieve the most even operation. The gearbox works on a hydrostatic mechanism, which allows you to manually set flexible settings when performing operations. This approach minimized the most common problems with the caterpillar undercarriage.Engineers have provided the machine with flexible handling and sensitivity, which allows the operator to perform even difficult maneuvers. The undercarriage is adjustable to achieve the greatest grip on the ground. Depending on the place of work, it is enough to select a specific mode in order to achieve maximum durability of the device. Hydrostatic mechanics involves the use of spare parts with a longer wear life, due to which the bulldozer is able to work for a long time without maintenance requirements. The architecture of the internal device is equipped with a ventilation system, which saves important components from the generation of harmful waste.
Review:
“I bought 3 bulldozers from Germany for construction work, I did not regret it. Cars show themselves perfectly, do not require repairs. Although the price is not the cheapest, but maintenance is rarely required, besides, stable operation and warranties from the manufacturer are expensive. Would recommend to anyone looking for quality equipment!”
The modern bulldozer market is able to offer a wide selection of copies for any type of construction or mining work. It is worth choosing a specific model taking into account further maintenance (the cost of spare parts) and delivery. The latest models of such equipment are manufactured in accordance with standards, so a potential buyer can count on at least a set of nominal features and capabilities, such as a wide viewing angle, a comfortable cab and a thoughtful canopy control system.
