Bulldozer T-170. Technical characteristics of the T-170 bulldozer

Despite the appearance of a huge number of modern brands of bulldozers on the Russian market recently, many of the old models developed back in Soviet times still enjoy great popularity. This applies, in particular, to the powerful T-170. This bulldozer was designed at the Chelyabinsk plant and was produced for 14 years.

History of the model

For the first time, the T-170 bulldozer, whose technical characteristics make it possible to judge him as one of the best Soviet models, left the assembly line in 1988. Workers of the construction and agricultural sectors of the national economy immediately appreciated the reliability of its assembly, capacity and excellent cross-country ability. At that time it was the most perfect heavy caterpillar tractor in the USSR.

When developing the design of this model, the T-130 bulldozer, which was successful in many characteristics, was taken as a basis . The T-170 was the same reliable, but more powerful and passable. Subsequently, ChTZ engineers further developed several modifications of this bulldozer. A little later, specially for the maintenance and repair of new equipment, the company Uralremtrac was also organized. This plant, like the ChTZ itself, still functions.

Scope of use

The T-170 bulldozer has such characteristics that it can be used for various kinds of agricultural, construction, road or even public works. To its undeniable advantages, among other things, include the possibility of using a huge number of types of attachments. Most often this model is used when:

• Leveling of earth embankments;

• Snow cleaning in winter;

• Leveling of construction sites;

• Rooting stumps and tree roots;

• Road construction.

Design Features

The T-170 bulldozer has received good reviews from specialists primarily for its power and high productivity. Its four-stroke engine can work on different types of fuel: diesel, gas condensate, kerosene. Modifications of the T-170 can be equipped with an electric starter or a carburetor motor.

Unlike most other models designed and built in the Soviet Union, the T-170 bulldozer is equipped with a very convenient all-metal large cabin for the mechanic. The unique design of the hydraulic system of this model, which allows you to change attachments with minimal effort and energy.

The dimensions of the T-170 bulldozer are such that it can easily be placed on the platform of a railway car. Of course, this makes it as easy as possible for the technician to deliver the equipment from the manufacturer or supplier to the work site. However, for movement on the roads on this bulldozer, you must first obtain permission to the traffic police, since it has significant dimensions.

Advantages and disadvantages of the model

In addition to a powerful engine, a comfortable cabin and a well-thought-out hydraulics, this model has other advantages. For example, design features such as liquid cooling of a diesel engine and the presence of a cold start system make it easy to start a bulldozer even at a temperature of -40 g.

These models break quite rarely. However, in the event of a malfunction, the repair of the T-170 bulldozer does not normally cause any problems. To buy from us in the country all the necessary details can be without problems. The company "Uralremrak" produces nodes and mechanisms for the T-170 technology regularly and in the required quantities.

The advantages of this model include:

• Adaptability for work in different climatic zones;

• Low cost.

Of course, T-170 bulldozers and certain drawbacks exist. To such it is possible to carry:

• Inconvenient complicated steering;

• Unreliable friction clutches, which have to be changed from time to time.

Soviet T-170 bulldozer: specifications

What exactly is this model, developed in the last century, is clearly demonstrated by the table below.

Of course, the drawbacks of the T-170 bulldozer are there. However, he deserved the popularity of specialists, as you see, not without reason. For its low cost, the T-170 bulldozer has very good technical characteristics.

Features of the chassis

Like all Class 10 crawler vehicles produced by ChTZ, the T-170 is equipped with five rollers. The width of its caterpillar can vary in quite a large range - 460-900 cm. Some modifications of the T-170 are equipped with 7 rollers. This technique, among other things, can be used to perform work on wetlands. The suspension of the tractor T-170 is semi - rigid, and therefore it does not differ by its smooth running. However, the presence in the construction of additions such as a rigid balancing beam and airborne spatial frictions ensure excellent cross-country ability of this bulldozer on hard ground.

Transmission system

The work on the T-170 bulldozer can be done using 8 forward and 4 rear speeds. Actually the transmission scheme of this tractor includes:

• Reliable dry type grip;

• Four-shaft transmission;

• PTO.

The gearbox on the T-170 bulldozers can be installed with the possibility of blocking the first feed and with the reducer of the cooler.

Hydraulic system

The reliable gear pump NSh-100 (one of the best) is responsible for the operation of this system in the T-170 bulldozer. The hydraulics of the model are classified as separate-aggregate. For its smooth operation, it is necessary to fill 100 liters of oil. The functioning of the attachments is provided by a three-position hydraulic distributor P 160 spool type. The maximum permissible pressure rating of this equipment is 16 MPa.

Cab of the bulldozer

As already mentioned, in terms of convenience for the driver also has a good bulldozer T-170 characteristics. And although it is inferior to its modern foreign and domestic counterparts in this respect, it is possible to perform work on it with relative comfort. Panoramic glass provides an excellent view. To improve the safety of work performance, the T-170 model cab is complemented by the ROPS-FOPS frame. Its presence allows you to prevent injury in the event of a rollover technique.

In winter, the T-170 bulldozer driver has the opportunity to turn on the heating system. Air conditioning in the basic model, unfortunately, is not included. However, the manufacturer, if necessary, can order its installation as an option. The chair can easily be adjusted to your own height, if desired.

Thus, the T-170 bulldozer has very good technical characteristics. Despite the fact that it has already been removed from production, it can be considered one of the best models available on the modern market in its price category. Some design deficiencies of the T-170 are more than offset by its functionality, ease of use and performance.
