No construction site or large-scale repairs are practically inconceivable today without the use of special equipment. Therefore, you should pay attention to the unit called the DZ-171 bulldozer. This car will be discussed in this article.

Basic information

The DZ-171 bulldozer, whose mass allows it to easily overcome various obstacles in its path, is the brainchild of the Chelyabinsk Road Construction Machines plant. But it is worth noting that today, among the nomenclature of this enterprise, the production of any tracked vehicles does not appear at all. It is in connection with this that the service of the described bulldozer simply does not exist, and in the event of a breakdown, you will have to rely solely on your own strength and the help of craftsmen.

Operating area

Bulldozer DZ-171 has found its wide application in many sectors of the national economy. In construction, it is actively used for digging fairly deep foundation pits and trenches. Also usingmachines carry out soil planning, its development and movement. In addition, the tractor allows you to create terraces on sites with significant height fluctuations.

Utilists are very fond of using the unit for the purpose of snow removal, as well as digging ditches and forming embankments. Reliable design and high power, in addition to all of the above, makes it possible to operate the bulldozer in the extraction of ore and coal, in the construction of bridges and various hydraulic structures.

Power plant

The DZ-171 bulldozer is equipped with a four-stroke four-cylinder in-line engine D-160.01. The engine is liquid cooled. A characteristic feature of the unit is the formation of a combustible mixture and its combustion in the chamber, which is located at the bottom of the piston.

The crankcase has special hatches for visual inspection of bearings and two drain holes. In order to reduce vibrations that occur during operation of the motor at a speed of 1250 revolutions per minute, a balancing mechanism is provided.

The diesel plant is equipped with a gas distribution device, which consists of a bracket, a shaft, valves with springs, a rod and a rocker arm. Each cylinder is equipped with an exhaust and intake valve.

The power system of the machine includes nozzles, a tank, a fuel pump, filters, a speed controller.

In turn, the cooling system is equipped with a centrifugal pump and has a closed circuit. The temperature is controlled inautomatic mode.

Driver's seat

The DZ-171 bulldozer, whose weight ranges from 17 tons, has a frame-type cabin that is quite modern for its generation of machines. Its characteristic feature is an impressive glass area, which provides a large viewing angle. The driver's seat has several adjustments.

The cab frame itself is quite rigid, which guarantees good protection for the operator in the event of a machine overturning or large and heavy objects falling onto the roof. The bulldozer was produced in two versions: for temperate and tropical climates. Depending on this, he had either an air conditioner or a heater. The dashboard of the car is also quite ergonomic and allows the driver to easily capture the data he needs.

Operation and repair

On what basis was the DZ-171 bulldozer created? T-170 - a tractor that is a prototype for the described unit. In this regard, the DZ-171 received a number of advantages, namely:

• Simplicity of design, which allows repair work without the use of expensive imported special tools and tools.
• High dead weight and powerful engine, which minimized competition for a bulldozer in its class.
• The highest degree of flotation in mud, snow, sand, off-road.
• The widest repair base, which has been preserved since the era of the USSR and is actively used today.
• No failures during sharp fluctuationsambient temperature.
• Low cost for spare parts and parts.

Of the negative aspects of the car, it can only be noted that, since it has tracks, when it is driven on asph alt, the latter cracks. Also, due to the fact that the bulldozer is no longer produced, every year it becomes more and more difficult to find truly high-quality components, but at the moment there are still a large number of them on the domestic market.

As long-term practice has shown, the design of the bulldozer is such that many repairs can be carried out by personnel with a rather low degree of qualification and without special education.

Parameters

The DZ-171 bulldozer, the technical characteristics of which are given below, has Shantui SD16 and TY165-2 as its imported analogues. The main indicators of the domestic tractor are:

• Length - 5700 mm.
• Width - 3065 mm.
• Height - 3420 mm.
• Operating weight - 17,000 kg.
• Traction force - 150 kN.
• Fuel tank capacity - 300 liters.
• Motor power - 125 horsepower.
• Forward speed is 2.5 km/h.
• Reverse operating speed is 12.5 km/h.
• Maximum ripper depth is 500mm.
• Swivel blade parameters (width x height) - 4100/1140 mm.
• Dimensions of a conventional blade (width x height) - 3200/1300 mm.
• Fuel consumption - 14.5 liters per hour.

Electrical equipment

Bulldozer DZ-171 has a five-phase non-contact electric machine. The output of energy is carried out through special terminals located on the back cover of the generator, which in turn is connected to the fan pulley. The electrical system has two batteries designed to activate the starter at the time of starting the engine and provide electrical energy to all consumers of the bulldozer when the engine is stopped.

As for the gearbox, it has eight speeds to move the machine forward and four to reverse.

In conclusion, we note that since the DZ-171 bulldozer has long been out of production, the cost of acquiring it is not so high. So, for example, a car manufactured between 1990 and 1993 will cost the buyer from 270,000 to 380,000 Russian rubles. If we talk about a bulldozer manufactured in 1999, then it will already cost about 600,000 rubles.
