Without the use of special equipment today, no construction site or large-scale repairs are almost unthinkable. Therefore, you should pay attention to the unit called the bulldozer DZ-171. This machine will be discussed in this article.
basic information
The DZ-171 bulldozer, the mass of which allows it to easily overcome various obstacles in its path, is the brainchild of the Chelyabinsk Construction and Road Machines plant. But it is worth noting that today, among the nomenclature of this enterprise, the release 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 case of breakdown it will have to rely solely on its own strength and the help of craftsmen.
Field of operation
The DZ-171 bulldozer is widely used in many sectors of the national economy. In construction, it is actively used for digging rather deep foundation pits and trenches. Also, using the machine, soil planning, development and movement are carried out. In addition, the tractor allows you to create terraces on sites with significant height fluctuations.
Public utilities love to use 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 point
The DZ-171 bulldozer is equipped with a four-stroke four-cylinder in-line motor D-160.01. The engine has liquid cooling. A characteristic feature of the unit is the formation of a combustible mixture and its combustion in the chamber, which is located in the lower part of the piston.
The engine crankcase has special hatches for visual inspection of the bearings and two drain holes. In order to reduce vibrations that occur during operation of the motor at a speed of 1250 per minute, a balancing mechanism is provided.
The diesel installation is equipped with a gas distribution device, which consists of an arm, a shaft, valves with springs, a rod and a rocker. Each of the cylinders is equipped with an exhaust and inlet valve.
The machine’s power system includes nozzles, a tank, a fuel pump, filters, and a speed controller.
In turn, the cooling system is equipped with a centrifugal pump and has a closed circuit. The temperature is controlled automatically.
Driver's seat
The DZ-171 bulldozer, whose weight varies within 17 tons, has a frame-type cabin that is quite modern for its generation of machines. Its characteristic feature is an impressive glazing area, which provides a large viewing angle. The driver's seat has several adjustments.
The cab frame itself is quite rigid, which guarantees good operator protection in the event of a car overturning or large and heavy objects falling on the roof. The bulldozer was produced in two versions: for temperate and tropical climates. Depending on this, he had either air conditioning or a heater. The dashboard of the car is also quite ergonomic and allows the driver to easily remove the data he needs.
Operation and repair
On the basis of what was the DZ-171 bulldozer created? T-170 - a tractor, which is the prototype for the described unit. In this regard, the DZ-171 received a number of advantages, namely:
- The simplicity of the design, which allows for repair work without the use of expensive imported special tools and tools.
- Large dead weight and a powerful engine that minimized competition for a bulldozer in its class.
- The highest degree of cross-country ability through 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 malfunctions during sharp fluctuations in the temperature of the environment.
- Low cost for spare parts and parts.
Of the negative aspects of the car, we can only note that, since it has tracks, the latter cracks when driving on asphalt. Also, due to the fact that the bulldozer is no longer produced, it becomes more and more difficult to pick up truly high-quality components every year, but at the moment there are still a lot of them on the domestic market.
As shown by many years of practice, the construction 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 counterparts. The main indicators of the domestic tractor are:
- Length - 5700 mm.
- Width - 3065 mm.
- Height - 3420 mm.
- Working weight - 17,000 kg.
- Bollard pull - 150 kN.
- The capacity of the fuel tank is 300 liters.
- Motor power - 125 horsepower.
- Speed forward - 2.5 km / h.
- The working speed of moving back is 12.5 km / h.
- The maximum depth of the cultivator is 500 mm.
- Parameters of the rotary blade (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
The DZ-171 bulldozer has a five-phase contactless electric machine. Energy is output 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 engine start and provide electric energy to all consumers of the bulldozer with the engine stopped.
As for the gearbox, it has eight speeds to move the car forward and four backward.
In conclusion, we note that since the DZ-171 bulldozer has long been discontinued, the cost of its acquisition is not so high. So, for example, a car produced between 1990 and 1993 will cost the buyer from 270,000 to 380,000 Russian rubles. If we talk about the 1999 bulldozer, it will already cost about 600,000 rubles.
