DZ 171 Bulldozer

The DZ 171 bulldozer is one of the most famous products of the Chelyabinsk street machine plant. Caterpillar chassis and 10th traction stroke made the technique the best option for working on hard ground.

DZ 171 is a classic example of a universal bulldozer, which has been used in various fields. At a relatively low price, the machine has excellent performance and long service life. The distinctive feature of the bulldozer is its unpretentiousness. It can be used in various climatic zones. The model shows high efficiency at temperatures from t-45 to +40 degrees.

The scope of application of the DZ 171 is really extensive. The main focus is to work on the ground (development, leveling terraces with uneven terrain, soil for short distances). The bulldozer is suitable for backfilling, pits and trenches that remain after the transfer of communications. In winter, the model is involved in clearing roads and meters from snow and debris.

DZ 171 is actively used by industrial companies in mining and coal industry. The bulldozer is used in the construction of roads, bridges, various structures and hydraulic structures. In agriculture, the model is used for soil work, reclamation and irrigation.

Modifications and functions

The basis for the creation of the DZ 171 bulldozer was the T 170.01 tractor. This series was widely used on the domestic market and had several modifications that differ from each other:

Type of fuel used (kerosene, diesel fuel and gas condensate);
Type of installed devices (various garbage collectors, scrapers, single- and triple-tooth rippers);
Execution (temperate and tropical).

The latest modification of the bulldozer was the DZ-171.1 version, which replaced the basic version. The machine differed by a larger blade and working weight.

Before the overhaul DZ 171 had a huge enterprise resource, which reduced consumer costs. Among other things, the models were listed:

A simple design that made repairs possible without special tools and fixtures;
Large weight and powerful power plant, which in its traction class DZ 171 had practically no analogues;
wide repair base, preserved from the Soviet times and actively used at the present time;
Absence of negative effects when working with sharp temperature changes;
Equality of elements and spare parts.

There are practically no disadvantages of the DZ 171 model. The only disadvantage is the end of production of this bulldozer and the presence of weak detailing. However, the unification and simplicity of design completely give away this disadvantage.

Under the foreign analogues of the model can be allocated bulldozers Shanui SD16 and TY165-2.

When developing the model, employees of the Chelyabinsk plant have studied several analogues produced in European countries, which are advanced in their segment. The result is an interesting model with its own features. The developers decided that the weight of the truck should meet domestic operating standards, so there is a fundamentally new model with upgraded elements.

When creating the DZ 171 there were certain difficulties. Nodes and engine T 170.01 do not finalize the large mass of the bulldozer, but certain modifications allowed to achieve good results.

The basis of the model is a solid frame. The main components are attached to it. The bulldozer is equipped with a standard chassis. The basic part includes a technological control machine and 5 rollers. A special chassis with 7 rollers and larger shoes (900 mm) is provided for the “Swamp” version.

The engine power reducer on the chassis is made by a mechanical transmission, which includes a combined hydraulic and mechanical connections. To reduce vibrations, a counterweight was defined in the rear of the hull, secured by a propeller. Speed shifting was accomplished by a clutch connecting the flywheel of the apparatus and the gearbox. To avoid idiocy when starting the engine, the engine was started only when the speed was in neutral. The gearbox had 8 forward speeds and 4 reverse speeds. Some modifications (swamp version) had a gearbox with 6 forward and 3 reverse speeds.

Maneuverability was provided by a lever control system. A belt-type friction system provided braking and rotation. Partial locking of the tracked machine allowed to change the direction of movement.

The bulldozer’s electrical system was provided by a five-phase contactless electrical machine. The power output was through terminals on the rear cover of the generator connected to the fan disk. The electrical system consisted of 2 accumulators, which powered the starter when the engine was started, and the power to the consumers was provided by the drill motor.

The cabin was designed in a frame version with extended soundproofing and sound absorbing materials. The frame design provided a good view of the working areas, and modern materials blocked vibration and noise. The cab offered enhanced protection for the operator, even if the truck tipped over. Heating and ventilation kept the operator comfortable regardless of the climate. Later versions of the bulldozer were equipped with air conditioning. The operator’s workplace was a seat with several adjustment mechanisms. The control lever and buttons were straight and made it easy to operate the machine. On the signal field were all the indicators needed to monitor the operation of the device.

There were two types of dozer blade installed in front of the bulldozer: rotary or non-cutting. Augers and hydraulic screws were used to change the angle of tilt and cutting. A three-tooth chipper was installed at the rear.

engine

In the standard version DZ 171, it was equipped with a 4-stroke engine D 160.01. A similar unit was installed in the modern version (DZ 171.1). In its traction class the performance of the bulldozer was one of the best. To avoid strong vibration of the equipment the counterweight was used, which was mounted with special stepped joints at the bottom of the machine.

A liquid mechanism with a centrifugal pump was used as the general cooling system. A standard paper filtration system and Multicicclone® unit were used for air purification. These units allowed to remove dust and fine particles with great efficiency in autonomous mode.

The bulldozer could run on almost any type of fuel:

on standard gas condensate;
diesel fuel;
on kerosene.

The D 160.01 engine was equipped with four operating cylinders, and the cylinder block was made of pure cast iron. Each block had one inlet valve and one outlet valve. The crankshaft, camshaft, and decompressor shaft were attached to the walls and bulkheads of the block. Bearing and tappet inspection lights were located on the right side of the block. Most of the mounting assemblies and power units were attached to the block. Fuel mixing and combustion took place in a chamber in the piston crown.

Bulldozer DZ-171: technical characteristics, price

This model is one of the most famous, produced by the Chelyabinsk enterprise, a manufacturer of street equipment. Everything about the DZ-171 bulldozer will tell in detail its technical characteristics, price and design features.

The Caterpillar platform has allowed this equipment to become the best option when it is necessary to carry out work on very heavy soil. The bulldozer is designed on a tractor platform. This versatile, very unpretentious equipment is used when it is necessary to level the terrain, backfill a ditch, move slabs, and clean a construction site. Although the serial production of units is already established, a pleasant ratio of price and reliable quality of performance provides the relevance of the bulldozer model DZ-171.

advantages

Since the basis for the model was a well-known tractor, this series of special equipment was widely used due to the availability of spare parts and had various modifications. These included:

The variant of fuel used.
The type of devices.
Type of maintenance.

The latest development released by the manufacturer is DZ-171.1. It came to replace the basic version, which was produced for many years. The bulldozer is equipped with a large blade, its working mass is much larger than in the previous model. Special devices had a significant resource of the company, due to which the cost of use is significantly reduced. Other advantages of the model are worth noting:

Simple design, which can be used to repair devices without special fixtures and special tools.
Low weight with high performance, thanks to the bulldozer, which has almost no counterparts in this traction class.
Extensive repair base, left over from the Soviet period, which is actively used.
Absence of negative moments during the operation of the enterprise, which is carried out in conditions where severe temperature fluctuations are possible.
Cheapness of the units and spare parts.
