Bulldozer T-130: technical characteristics, weight, price

History of creation

During the years when the Great Depression befell the American state, their company from Detroit signed a contract for the construction of a tractor plant located in Chelyabinsk. The base model of the future domestic tractor was the Caterpillar-60. Already in 1933, the first car rolled off the assembly line, named “Stalinets-60”.

During the difficult years of the Second World War, production facilities were directed to the production of self-propelled guns and KV tanks, tractors transporting howitzers. After the war, the Chelyabinsk enterprise produced a multifunctional tractor, the famous “weaving”. The unit broke several world records. The T-130 modification became a direct descendant of the famous Sotka. This bulldozer is still in mass production.

Dimensions of the T-130 bulldozer and main technical characteristics

Engine

The first cars of this brand were equipped with D-130 engines, but already in 1981 they were replaced with more powerful D-160 diesel engines. Their main advantages are unpretentiousness and guaranteed reliability. Over many years of operation, the engines demonstrate quite stable operation, despite extreme conditions.

But in severe frosts, the machine operators were unable to quickly start the mechanism. Because of this, those tractors that were sent to the northern regions were equipped with a pre-start heating system for both the engine and any technical fluids. The units demonstrate reliable operation on diesel fuel of any quality; they can be started on kerosene or gas condensate.

Chassis control

The suspension of the unit is semi-rigid and has a transverse spring for balancing. The frame is made from 2 stamped spars, which are combined with the rear axle assembly. The track web connects stamped tracks with metal pins.

The design of the chassis of the T-130 tractor

The installation is controlled by using a lever system through a set of belt clutches. To make a circular turn with a bulldozer, a rotary coupling is used. It is attached to the rear of the axle and connected to the drive gears through shafts. By using a band brake attached to a rotary coupling, it is possible to turn the machine almost in place, without moving.

The gear ring is fastened with twelve tight-fitting bolts 41 with nuts to the hub flange 42. The nuts are locked in pairs with plate washers.

The large diameter hub 42 rotates on cylindrical roller bearings pressed onto the axle shaft. Roller bearings only support radial loads, while ball bearings support axial loads that occur when turning. A spacer 51 is installed between the outer and inner bearings; the entire package of parts is tightened onto the axle shaft with lock nut 14. During operation, the final drive bearings are not adjusted.

The cast drive wheel 55 is centered on the hub and secured to it with ten tight-fitting (precise) studs 16 and pressed nuts 17.

In the outer end part of the hub, 10 holes are drilled for fit pins 16. The drive wheel 55 is connected to the hub using split conical bushings 19.

Conical bushings 19 with compressed nuts 17 screwed onto the studs, the outer surface is in contact with the conical bores of the drive wheel 55, and the inner surface is in contact with the outer ground surface of the stud 16, forming a backlash-free connection.

The oil bath of the final drive is sealed by two metal mechanical comb seals (small and large). Each seal consists of a movable and stationary disk and a rubber lip.

The fixed disc of the small seal is floating, movable 5 is centered in the hub and rotates with it. The fixed disk 6 is pressed against the movable one by a central spring.

The fixed disk 54 of the large seal is also floating. It is prevented from turning by two crackers located on the axes, which fit into the grooves of the large seal flange. The movable disk 21 rotates together with the drive wheel. The large seal discs are compressed by radial springs spaced evenly around the circumference. Rubber cuffs are placed on the outer diameters of the stationary seal discs and are connected to the body parts.

The rubber cuff of the large seal is protected by a two-way labyrinth, the moving part of which 20 is connected to the drive wheel, and the fixed part 23 is connected to the casing.

The axle bearing 7 is mounted on the track bogie using two bushing pins and secured with four bolts.

Rubber sealing rings are installed between the large seal stationary washer and the labyrinth, as well as between the drive wheel, labyrinth and hub.

The bearing of the axle shaft 7 is secured to the cylindrical part with a nut 12. One end of the axle shaft is connected to the bearing, the other end is pressed into the conical hole of the rotation coupling housing and is additionally secured with a nut 47, locked with a special spring ring 46. Thus, the axle shaft is rigidly connected to the rotation coupling housing.

To ensure that the drive wheel is in the same plane with the tension wheel and the center line of the rollers, there are shims 8 between the axle bearing and the bearing cover.

The final drive gears and bearings are lubricated by oil sprayed from the rotating gears. Oil is poured into

final drive through the pipe located in the flange of the side wall of the rotation coupling housing, to the marks on the oil gauge line.

A magnetic plug 53 is screwed into the lower part of the final drive casing. A radial self-clamping seal is installed in the final drive between the drive flange 30 and the bearing housing 36.

The end bearing bushing is lubricated through a grease nipple screwed into its cover. This cavity is sealed with a radial self-pressing seal.

The final drive of a swamp tractor is different from the gearbox described above; Since the track of this tractor is 400 mm wider than the base track, some parts of the final drive (axle shaft 9 (Fig. 66), hub 3, spacers 1 and 2) are lengthened.

Cabin

The operator's seat is located in a cabin with panoramic glazing and a reinforced frame, which ensures a safe stay for a person inside. Factory designers competently designed the driver’s work area, carefully considering the location of all instruments and control levers so that the operator could comfortably perform the assigned tasks.

Engine control system for bulldozer T-130

T-130 cockpit and controls

The chair is equipped with convenient tilt and height adjusters, which ensures that the worker can achieve a posture in which he feels comfortable while working. Reliable insulation from dust and noise ingress is achieved using soft rubber seals. Thanks to the heating system, the room quickly heats up in cold weather.

Device

The T-130 bulldozer was equipped with a four-stroke diesel engine D-130 (140 horsepower), which became obsolete already in the 70s. Since 1981, the model began to be equipped with an improved four-cylinder D-160 turbocharged unit (160 hp). It was started using a gasoline engine. This installation was received by a significantly modernized version of the T-130 - the T-170 bulldozer.

The model received an 8-speed manual transmission, including a clutch (permanently closed), four discs (two driven, two driven) and a four-shaft gearbox. Bulldozers of this type were equipped with a floating, band brake system.

The ability to mount a power take-off shaft made the T-130 multifunctional, allowing it to be used with a variety of equipment for many industries. The operator's cabin in this model is located at the rear and is designed for two people. It has sound and thermal insulation, which allows you to “smooth out” unpleasant conditions outside and make working with equipment more comfortable. But the control of the bulldozer is far from ideal. During operation, a strong vibration emanating from the control levers is clearly felt. This is due to their direct connection to the transmission.

Video

The Chelyabinsk Tractor Plant installed additional options in the T-130. They allowed oil, air and water to be heated before launch. again, tracks were installed for driving on asphalt, advanced useful devices and specialized equipment for driving on ice.

Note that by the time serial production of the T-130 started, its design, developed back in the 30s, was very outdated. The imperfect mechanical transmission did not allow the engine power to be fully realized. Problems were felt under significant load. The process of operating a bulldozer was not easy. The semi-rigid suspension, which significantly limits the capabilities of the equipment, was not the best solution. It “slowed down” the traction potential of the T-130. The service life of the onboard clutches, which had not been changed since the time of the S-80 model, was frighteningly short. The general engine was started using a starting gasoline engine, which did not start at low temperatures. The vibration from the control pedals and levers was very strong.

Attachments

The set of attachments on the tractor is hydraulic, separate and modular. It is designed to perform the necessary work using two types of attachments: rear and front (pendulum or rigid). The hydraulic system of a separate-aggregate type serves the functioning of a trailed or mounted device.

A bulldozer blade of one of two types (2.5 or 3.2 m wide) is attached to the front linkage. Various uprooters or rippers, systems for driving piles or laying pipes, and equipment for moving timber are attached to the rear linkage. The clean version of the T-130 has proven itself positively when working in the field: it is convenient for them to plow virgin, previously uncultivated lands.

At the buyer’s request, the machines are equipped with any of the possible attachments: a straight or hemispherical blade, a ripper with one or several teeth. The passport parameters of the attachments are summarized in the table:

Bucket option	Hemispherical	Straight
Method of changing the angle of transverse skew and cutting	hydraulic together with screw braces

Electrical circuit of the T-130 bulldozer
However, the tractor also has certain disadvantages. It is quite difficult to start a car in severe frost if it is not equipped with a pre-start heater. Power equipment produces excessively loud levels of vibration and noise. The unit turns jerkily, and traces of water often appear in the oil.

The side clutches of a bulldozer often break and drivers cannot understand why the reverse gear has disappeared. Also among the negative qualities is the heavy weight of this tractor.

Price

It is impossible to buy a new bulldozer of this modification now, since its production was discontinued three decades ago. But the secondary market offers a wide selection of such used special equipment.

A used car will cost a needy consumer approximately 300–450 thousand Russian rubles. The final cost is influenced by the volume of operating hours, operational condition and year of manufacture of the unit.

Analogs

When it comes to analogues of the domestic bulldozer of this modification, their availability in the vastness of our state is sufficient. The most approximate technical indicators are characteristic of three models: TM-10, Caterpillar D6R and B10M. They are characterized by the following parameters:

Brand	Weight, t	Nameplate power of the power unit, hp	*Declared fuel consumption, g/kWh**	Filling tank for diesel fuel, l
TM-10	18,5	180	213	300
Caterpillar D6R	18,2	175	215	420
B10M	15,3	190	218	320

But it was the ChTZ-130 model that became the most striking and capacious representative of our domestic mechanical engineering, since it absorbed all the high production potential of the USSR industry and the design genius of Soviet engineers.

Reviews

Many ChTZ-130 users share their experience in operating this equipment. They leave reviews from bulldozer owners on specialized forums, highlighting the features of the machine and its quality. If we synthesize these records, we get the following summary characterizing the unit from the consumer's point of view:

Installation is convenient due to the availability of spare parts in retail chains, so its repair is not too complicated.
The unit causes virtually no problems when refueling it even with low-quality domestic diesel fuel.
The technical characteristics of this tractor model allow it to be used effectively in the construction or resource-extracting industries.
The machine has a spacious cabin, the driver is able to clearly view the work area. The body is equipped with lighting devices, which are sufficient for good visibility at night or in bad weather conditions.
Almost all consumers cite a weak gearbox as a disadvantage, which only worsens the car’s handling, seriously reducing its overall efficiency.
The weight of the bulldozer is quite significant, and users have similar comments about the components. Because of this, without the use of lifting devices, quite a lot of problems arise when trying to replace components of the chassis system or power equipment.
An important problem of the power plant is its inability to run idle for a long time. When the engine “rumbles” at idle for a long period of time, the turbine soon begins to leak oil and therefore breaks down. The reason is the virtual absence of oil entering the engine, which is necessary to lubricate the pistons. The turbine operates without oil, the wear of its parts increases, which provokes breakdown.
Also among the significant disadvantages are bolted track shoes. The fasteners periodically become loose, which is why it is necessary to constantly monitor them, check the integrity of the shoes, and tighten them.
During the Soviet Union, operating a tractor was a pleasure, since diesel fuel cost almost nothing. The situation is completely different now, when diesel fuel is very expensive. Because of this, modern equipment owners note the greater productivity of this machine, but also its high fuel consumption. In order to use the unit profitably, it is necessary to provide it with significant volumes of work. When you compare this model with the DT-75, you immediately notice that the T-130 is much more productive and efficient, but consumes twice as much diesel fuel. Because of this, it must be used on large construction sites: when constructing dams, cleaning large sites, creating road junctions, laying process pipelines.

The tractor is distinguished by excellent technical parameters, thanks to which it is even now successfully used in many public utilities and construction organizations.
