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

Despite the emergence of a huge number of modern brands of bulldozers on the Russian market recently, many old models developed back in the days of the USSR are still very popular today. This applies including the powerful T-170. This bulldozer was designed at the Chelyabinsk plant and was produced for 14 years.

Model history

For the first time, the T-170 bulldozer, the technical characteristics of which make it possible to judge it as one of the best Soviet models, rolled off the assembly line in 1988. Workers in the construction and agricultural sectors of the economy immediately appreciated the reliability of its assembly, power and excellent cross-country ability. At that time it was the most advanced heavy tracked tractor in the USSR.

When developing the project of this model, the T-130 bulldozer, successful in many characteristics, was taken as the basis . The T-170 turned out to be just as reliable, but at the same time more powerful and passable. Subsequently, ChTZ engineers additionally developed several more modifications of this bulldozer. A little later, specifically for the maintenance and repair of new equipment, the Uralremtrak enterprise was also organized. This plant, like ChTZ itself, is still functioning today.

Scope of use

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

• leveling earthen embankments;

• snow removal in the winter;

• alignment of construction sites;

• uproots of tree stumps and roots;

• road construction.

Design features

The T-170 bulldozer from experts earned good reviews primarily for its power and high performance. Its four-stroke engine can run on different types of fuel: diesel , gas condensate, kerosene. Modifications of the T-170 can be equipped with an electric starter or carburetor engine.

Unlike most other models designed and built in the Soviet Union, the T-170 bulldozer is equipped with an all-metal large cabin that is quite convenient for the machine operator. The hydraulic system of this model also differs by the originality of the design, which allows changing attachments with minimal effort and energy.

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

Advantages and disadvantages of the model

In addition to a powerful engine, a comfortable cab and thoughtful 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 gr.

These models break quite rarely. However, when a malfunction occurs, repairing the T-170 bulldozer usually does not cause any difficulties. You can buy all the necessary parts in our country without problems. The Uralremtrak enterprise produces components and mechanisms for the T-170 equipment in an orderly and necessary quantity.

The advantages of this model can also include:

• adaptability to work in various climatic zones;

• low cost.

Of course, T-170 bulldozers also have certain disadvantages. These include:

• uncomfortable complicated steering;

• unreliable friction clutches that have to be replaced from time to time.

Soviet bulldozer T-170: technical specifications

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

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

Chassis Features

Like all class 10 tracked vehicles manufactured by ChTZ, the T-170 is equipped with five rollers. The width of its caterpillar track can fluctuate in rather large limits - 460-900 cm. Some modifications of the T-170 are equipped with 7 rollers. This technique, among other things, can be used when performing work in wetlands. The suspension of the T-170 tractor is semi-rigid, and therefore, unfortunately, it does not differ in special smoothness of travel. However, the presence in the design of such additions as a rigid balancing beam and side spatial friction clutches provide excellent cross-country ability of this bulldozer on hard ground.

Transmission system

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

• reliable dry grip;

• four-shaft gearbox;

• PTO.

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

Hydraulic system

The reliable gear pump NS-100 (one of the best) is responsible for the operation of this system in the T-170 bulldozer. The hydraulics of the model is classified as separate-aggregate. For its smooth operation, you need to fill 100 liters of oil. The functioning of attachments is provided by a three-position directional control valve P 160 of the spool type. The maximum permissible pressure parameter of this equipment is 16 MPa.

Bulldozer cab

As already mentioned, in terms of convenience for the driver, it also has good T-170 bulldozer characteristics. And although it is inferior to its modern foreign and domestic counterparts in this regard, you can perform work on it with relative comfort. Panoramic glass provides excellent visibility. To increase the degree of safety of work, the T-170 model cabin is supplemented with a ROPS-FOPS system frame. Its presence helps prevent injury in the event of a rollover.

In winter, the driver of the T-170 bulldozer has the ability to turn on the heating system. Unfortunately, air conditioning is not included in the basic model. However, if necessary, the manufacturer can order its installation optionally. The chair, if desired, is easy to adjust to your height.

Thus, the T-170 bulldozer specifications are actually very good. Despite the fact that it has already been discontinued from production, it can be considered one of the best models available on the modern market in its price category. Some of the design flaws of the T-170 more than overlap with its functionality, ease of use and performance.
