The bulldozer is the only machine without which any work related to the development of the soil can not do. The speed of all operations at a construction site depends on its performance. Therefore, when choosing, attention should be paid not so much to modern models as to time-tested representatives.
If you choose among domestic equipment, then the choice should fall on the DT-75 bulldozer, which in 2013 celebrated its half-century anniversary. For over 50 years, it has been constantly upgraded and now meets all modern standards and requirements.
Keeping up with the times
The most relevant bulldozer model to date is AGROMASH 90TG. It was released in 2009. Its design has not changed much, only now the specimens are equipped with Finnish-made Sisu diesel engines that comply with international environmental standards. But designers are now working to improve performance and operational potential.
As of today, the DT-75 bulldozer is one of the most comfortable for work from representatives of multi-purpose tracked vehicles. Design features of the machine allow you to work on it in all weather conditions.
The cabin is equipped with a filtration and humidification system, as well as a heater of a calorifer type, which creates comfortable working conditions in any region of Russia.
Specifications
Technical indicators of the model strongly depend on its modification, as well as on the type of engine installed. We will present the characteristics of the DT-75 bulldozer , which is equipped with a power plant with a capacity of 95 hp, because this model of equipment is the most popular today.
Currently, the bulldozer is supplied to the market in four basic trim levels. The DT-75 C1 model is characterized by additional hydraulic components, remote cylinders and a rear linkage. The instance under the C2 index is equipped with a distributor and a hydraulic tank. DT-75 C4 differs from the first configuration only in the absence of an external cylinder, and the C3 model is delivered original - without additional equipment.
Design features
Like 50 years ago, the DT-75 bulldozer is assembled on a frame welded from longitudinal spars. The rear axle and gearbox are still located in the rear section. This arrangement makes the tractor as stable as possible.
The wide caterpillar track - from 390 mm to 470 mm, depending on the configuration - gives the technique high traffic. The model can be operated on the soil of any group, in wetlands and off-road. At the same time, the ground clearance varies from 326 to 380 mm, which allows the use of a bulldozer for clearing rubble, cleaning large-fragment construction debris.
The DT-75 bulldozer is equipped with hydraulics, which includes long-stroke cylinders, due to which it was possible to reduce the working pressure in the system and optimize its work, thereby increasing its durability and productivity of the tractor as a whole.
Engine and transmission
Regardless of the configuration and model, engine power is at the level of 90-95 hp. Typically, this is a four-stroke four-cylinder engine with a liquid cooling system. The launch of the power plant is carried out by an electric starter powered by a battery. For operation in ultra-low temperatures, the pre-heater -200 was installed on the presented bulldozer. You can see the photo of the car below.
The transmission is represented by a 15-speed manual gearbox: 10 ranges for forward operation, and 5 for reverse. Clutch - double disc, dry, permanently closed type. Thanks to it, with an increase in torque and when an obstacle occurs, the tractor tractive effort increases.
Bulldozer cost
The price of a bulldozer depends on many factors. Firstly, from the configuration of the model. Secondly, from the trading floor. Thirdly, from the region of purchase. In view of the above circumstances, the price for a bulldozer varies from 700 thousand to 1.6 million rubles.
The cost of production is also significantly affected by the model year of manufacture. Moreover, if for supported copies of 1990-2002 they ask from 180 to 300 thousand rubles, then for 2010-2017 models not less than 800-900 thousand. The last restyled version of 2009 with Finnish Sisu engines with a capacity of 100 horsepower is within 1, 5 million rubles.
The presence of additional attachments can also slightly affect the price. As a rule, the factory model comes with a rotary blade, which can change the angle of inclination in several planes. Its cost is in the range of 100-110 thousand rubles. A power take-off shaft can also be used as additional equipment. In this case, the price for a bulldozer increases by another 10-12 thousand.
User reviews
During the operation, drivers noted a number of advantages of the bulldozer, which distinguish it from other representatives of multi-purpose tracked vehicles. Especially often the exploiters noted:
- high cross;
- unpretentiousness to local and weather conditions;
- high maintainability;
- availability of spare parts;
- low fuel consumption;
- optimum dimensions for work;
- high performance.
Separately, some customers note endurance - tracked vehicles work without effort for several shifts without interruption. The cab also received good reviews, but only with modern models. It emphasizes a good overview, an ergonomic dashboard, which is missing all the excess. Attention was also paid to the high functionality of the tractor due to the wide range of attachments.
The minus drivers usually call the lack of rear-view mirrors - you have to focus on your own instinct. But this problem is solvable. Missing turn indicators are less distracting from work.
In conclusion, it is worth saying that the model is suitable for most of the operations at a construction site. Despite its age, the bulldozer has retained its popularity. The photos presented in this article cannot reflect all the splendor of this technique. It must be seen only personally.
