Bulldozers belong to the category of self-propelled vehicles, with a track, designed for digging 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.
Continuous production of machines for digging the ground 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 dates back to the 80s of the last century and has since 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 provide 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, named Ty-220, went to the aid of the miners. The model worked for almost 30 years and over 20 thousand working hours. During the above period, the machine requested a total of 3 maintenance services. With such a length of service, the number of capital services is negligible, so the equipment from the Chinese plant received the fame of reliable working machines. The following models of bulldozers are produced under the wing of the company:

“I am using a machine from the Sd52 range, as this is the one provided by the construction company. My job is to prepare the site, dig the foundation for the construction of apartment buildings. The bulldozer shows excellent results and solid reliability compared to other machines in this category that I have worked on before. For 1.5 years of operation, no maintenance was required, moreover, the model shows itself from the best side even when working with problem soil. I recommend Shantui bulldozers! ”
The company is based in the USA and holds a leading position in the global market for special equipment designed for construction, earthmoving and related work. The company manufactures bulldozers with a chassis on a caterpillar. The range includes copies of all power categories: from weak to high power models.
The company's bulldozers are equipped with an engine from the same company. Cat engines are famous for their thoughtful mechanics of distributing waste gas, as well as an advanced electrical control system for the machine and calculating the dose of fuel supply. In addition, the architecture of the engine implies the presence of adjacent cooling systems, which significantly increases the service life of the bulldozer without repair.
Automatic control mechanisms are integrated into the machine to achieve the highest accuracy during work. The on-board computer is equipped with a tracking system associated with the satellite, which allows you to record the operations carried out on the bulldozer (up to the operating hours 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 competent use of working space. Machine condition and data required for operation are displayed on the on-board computer screen. The seats meet modern comfort requirements, 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 making 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 relieve the operator of unnecessary irritants.

“I am the founder of a construction organization and I was faced with the question of buying high-quality equipment for digging foundation pits. At 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 renowned manufacturer. The choice fell on Kat and paid off in full! The bulldozers of this brand show excellent results in terms of stability, and the operator gives only positive feedback on their work. For the entire time of ownership, there were no problems, the cars did not require repair, 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 firm is considered one of the largest in its native country. It specializes in the production of vehicles with a tracked chassis. 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 at an angle so that the operator has a wide view of the site.This 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 worker with a choice between manual control or automatic control with an indication of the upper speed limit. The gearbox system on hydraulics does not need auxiliary braking elements, this gives flexibility in control. The checkpoint is electronically controlled, so all related operations are carried out automatically.
Enhanced comfort for bucket operations. The canopy mechanisms distribute the pressure evenly and allow for the greatest balance under load. The employee controls the bucket using a joystick, there is the possibility of switching between working angles.
The stress on the gaskets and the operator is minimized. The automatic mechanics balances even high loads, which improves the overall efficiency of the operations and reduces the consumption of fuel resources.
The salon meets modern standards of comfort, is equipped with protection against extraneous noise, shock and working vibrations. A similar effect is achieved with technical gaskets.
The company provides the opportunity to order specific attachments. The buyer can place an order for buckets of any shape, size and format, just fill out the form and leave an order with the design requirement.
Feedback:
“I work for hire as a bulldozer operator. Over the course of the operator's practice, I had to change a dozen different machines, so I can form an informed opinion about the advantages and disadvantages of various models. Bulldozers from Komatsu are distinguished by increased comfort in terms of work and being in a working chair. The work of the engineers is noticeable, because the viewing angle is as comfortable as possible in almost any position. The gear control is implemented with all the conveniences, it is easy to get used to the gearbox, and it is pleasant to change gears. "
The Chelyabinsk enterprise for the production of tractor equipment is considered one of the largest industries in the territory of the Russian Federation, whose specialization is the manufacture of special equipment of all categories. The enterprise dates back to the 33rd year of the last century.
The buyer's choice includes a series of bulldozers:
The buyer is provided with a wide selection of machines of various specifications and prices. It is worth noting that the purchase of Chelyabinsk bulldozers is more affordable than foreign ones, because the payment includes not only the price of equipment, but also the cost of delivery, and if the product is domestic, then the delivery is several times cheaper.
Feedback:
“My company is involved in 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 a foreign one. In operation, the Chelyabinsk bulldozer shows strong results. Breakdowns have occurred, but spare parts for domestic devices are also available, which greatly simplifies maintenance. I recommend the bulldozers from the Chelyabinsk manufacturer to anyone looking for a strong car for adequate money! ”
A special purpose machinery company based in Germany dates back to 1949 of the 20th century. The company specializes in the production of bulldozers of medium and high gravity categories. The 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 balances power and load to achieve the most uniform performance. The gearbox operates on a hydrostatic mechanism, which allows you to manually set flexible settings when performing operations. This approach minimized the most common tracked suspension problems. The engineers have provided the machine with flexible handling and responsiveness, allowing the operator to make even difficult maneuvers. The undercarriage adjusts for maximum traction. Depending on the place of work, it is enough to select a specific mode in order to achieve the maximum durability of the device. The mechanics of hydrostatics implies the use of spare parts with a longer service life, due to which the bulldozer is able to work for a long time without maintenance requirements. The architecture of the indoor unit is equipped with a ventilation system, which removes harmful waste from important components.
