Technical characteristics of tractor DT-75 and its features

On the account of Volgograd Tractor Plant there are many powerful and hardy models that help a person in all spheres of activity. But the most outstanding representative of the concern is rightly considered a crawler tractor DT 75. The combination of a powerful engine and caterpillar running gear allows him to easily perform various types of work.

Over the years of its existence, it spawned several modifications, which is not surprising - in 2013 it was marked by a half-century anniversary. But, despite its age, the tractor remains popular and in demand in modern enterprises.

Specifications

To its long existence the tractor is obliged to reliable construction. It is thanks to it that it is distinguished by its high reliability, power and maintainability.

The most modern version today is the 2009 version, which is equipped with a Finnish Sisu engine. But even with a standard motor, the technical characteristics of the tractor DT 75 can cause envy in many foreign analogues:

• Rated power - from 58.8 to 70 kW, depending on the type of engine;
• Rotation speed - 1800 rpm;
• Fuel consumption - 226,6-220,0 g / kW * h;
• The maximum speed is 12 km / h;
• The number of front gears is 5 (with a speed reducer - 23, with a reverse gear - 14);
• The number of rear speeds with a speed reducer is 14, with a reverse gear - 7.

It should be said that the indicators largely depend on the modification and pre-installed power unit. The presented technical specification of the tractor DT 75 corresponds to the standard transmission and engines AI41 and D-245.5S2.

Running gear indicators

The undercarriage itself consists of guiding and driving wheels, balancing carriages and two caterpillar chains. The tension of the last elements is answered by supporting rollers with rubberized bandages. The standard running gear corresponds to the following technical specification of the tractor DT 75:

• The length of the longitudinal base is 1612 mm;
• Track width 1330 mm;
• Ground clearance (ground clearance) - 370 mm;
• The width of the caterpillar chains is 390 mm.

The presented indexes of the undercarriage correspond to the average structural (operational) ground pressure equal to 47 kPa.

dimensions

The frame of the caterpillar tractor is welded from two longitudinal longitudinal members of a closed rectangular cross-section, which are connected to each other by cross-links. The rotation of the machine is carried out by suspending one of the caterpillars, for which the planetary mechanism is responsible.

The size of the crawler tractor DT 75 will depend primarily on its modification. So, for modern models the following indicators are characteristic:

• Length of the body - 4240 mm, in combination with the rear attachments in a position ready for movement - 4530 mm;
• Width of the body - 1850 mm;
• Height - 2705 mm, can vary within 30 mm in both directions.

Indicators of the mass of the tractor depend on the type of installed power unit. For models with the A-41 engine, it is 6530 kg, and for representatives equipped with a D-245.5S2 diesel unit, it is 6000 kg. The technical characteristics of the tractor DT 75, namely the operating weight, varies depending on the type of attachments.

Cabin

Comfortable working conditions for the driver are provided by a modern cabin. In its composition it has a heating system, which makes it possible to work in the winter. To damp the vibrations of the engine and other construction equipment, a vibration-proof material is placed in the compartment with waterproofing.

Observation of the working process will not prevent any weather conditions, because the cabin is equipped with a front and rear wiper, which is able to remove both a thin layer of ice, and a glass washer. Progressive tractor DT 75 bulldozer for work in the summer is completed with air conditioning.

Design features

One of the significant design features of the tractor DT of the first 75 years of production is the diesel engine starting system. The parameters of the unit do not allow the motor to start using an electric drive. Therefore, the start is responsible for an additional petrol engine, which is already powered by an electric starter.

Another feature of the models can be called the preheater diesel fuel, which turns on the work at an ambient temperature of less than -5 degrees Celsius. If necessary, in particularly low working capacities, the agricultural tractor DT 75 can be equipped with a speed reducer.

Scope of application

The scope of the tractor is quite extensive. He proved himself well at the construction site, especially during the construction of large foundation pits for massive objects. They can move ground masses by drawing by installing a direct blade. For the loading of land in dump trucks, spherical dumps are installed on the model.

Often a heavy machine is used as a tractor for transporting particularly massive objects. In this case, it is equipped with a pendulum or rigid trailing device. But DT 75 is well-known as an agricultural tractor. Among the attachments there are elements for the field - seeders, potato diggers, plows, baking equipment, harrows.

Cost

The cost of tracked tractors varies considerably depending on the region. At the present moment in the market of bulldozers the most represented are used models. Their price starts to grow from 250 thousand rubles and depends on the condition, technical equipment and year of release.

On factory models of modern years of release (2016) cost starts to grow from 1,7 million rubles. But the most promising remains the tractor DT 75 modified in 2009. Its price corresponds to the power and reliability, it will satisfy any customer counting on long-lasting equipment.
