Bulldozer b10m: technical characteristics

One of the most reliable and frequently used bulldozers of the 10th traction class is the B10M. This model of equipment is reliable and has outstanding performance parameters. The main purpose is to work with soils of categories 1-3 without preliminary loosening, as well as category 4 with preparation for processing.

The B10M bulldozer is a tractor for cultivating soil and for solving a large number of different tasks at a construction site and when felling timber. The basis for the creation of this equipment is tractors such as T-10 and T-170. The main differences between the B10M and its prototypes are the following points:

The design uses special long-stroke hydraulic cylinders;
the suspension beam is used together with a special balancer;
placement of main components in the engine compartment;
productivity increased by 20%.

Can be used under different climatic conditions and temperature conditions.

Bulldozer B10M: history of creation

Tractors such as T-10 and T-170, despite their outstanding performance characteristics and other advantages, are obsolete. That is why at a certain moment there was a need for a more powerful analogue. It was the B10M bulldozer. This equipment was developed at the Chelyabinsk Tractor Plant - ChTZ.

industrial tractor T-170 was produced in the years 1988-2002. – also at ChTZ. At the moment, there are just under a hundred modifications of this tractor. Despite the fact that this model has ceased to be produced, it still continues to be used. Primarily due to the low price, as well as unpretentiousness.

An inexperienced eye may confuse the T-170 and the B10M bulldozer. Since when creating a newer tractor, the chassis from the T-170 was used. But that's actually where the similarities end. The B10M is equipped with more powerful engines and is also more productive. Immediately after the production of the T-170 ceased, the first B10M rolled off the production line.

Operator's cabin

To maintain normal temperature in the cabin, a heating and air ventilation system is provided. It uses the heat from the coolant for heating. The B10M bulldozer is also equipped with a curtain for protection from sunlight and a driver’s seat, which is adjustable to his needs. The cabin is double glazed, visibility is quite large. The front and rear windows are covered with bars for security purposes. The instrument panel is visible even when the sun hits, allowing the operator to respond to signals in a timely manner. Security systems - FOPS and ROPS allow you to feel comfortable in any situation.

Technical characteristics of B10M

The technical characteristics of the B10M deserve special attention. They are what make it one of the most popular tractors in its class. Today the B10M has only one foreign analogue, which is comparable both in price and parameters - this is the Chinese bulldozer Shantui sd16. But the domestic analogue is several times easier to repair.

Dimensional and mass indicators

With quite impressive power, the mass and overall dimensions of this equipment are relatively small. Which is also a significant advantage.

Engine

The type of equipment under consideration can be equipped with two different engines. Their parameters differ slightly from each other. Each has its own characteristics.

That is why, before purchasing a certain modification, you should carefully familiarize yourself with them. Since the comfort of operation will depend on this.

Types and characteristics of engines used:

Bulldozer modification	T10M.000	T10M.6000
Model of the installed unit	D-180	YaMZ-326N-3
Unit type	4 cylinders arranged in a row	6 cylinders, V-shaped

YaMZ has more power and is easier to start, but at the same time fuel consumption is significantly higher. It should be remembered that there are significant differences in designs.

YaMZ is more expensive to maintain and is more difficult to deal with.

Transmission

The B10M bulldozer uses a standard mechanical gearbox to transmit torque - three-speed, planetary, reversible. A two-stage gearbox with spur gears is used. The box uses a total gear ratio of 14.79. The driving mechanism is a sector gear reducer. The hubs are installed by spline mounting.

Travel speed with a standard gearbox installed, km/h:

Broadcast	First	Second	Third
Forward movement	0-3.61	0-6.4	0-10.09
Moving backwards	0-4.48	0-7.49	0-12.51

Chassis (transmission)

The bulldozer's chassis is similar to that used on the prototype - T-170. The suspension is three-point. There is a balancing beam, suspended by small springs. Tracks with a sealed lubrication joint are used. Main characteristics:

Cabin B10M. Bulldozer control

The technology in question uses a frame, rigid metal cabin. Its most significant advantage is the all-round visibility - 3600 around the car. The main features of the B10M workplace are the following:

special heating installation, multi-mode - allows comfortable operation even in the Far North;
in some models, an additional oil heater is installed for operation at critically low temperatures;
A PILOT type driver's seat is installed (it is comfortable and vibration-proof).

On request, it is possible to additionally install special protection for the driver from objects falling from above. Which is especially convenient in conditions of forest felling and construction work.

Driver's seat

Winch control

It is possible to install a winch, the torque to which is transmitted through the power take-off shaft. Allows you to perform the following actions:

towing work - especially convenient when laying communications in the ground;
elimination of various rubble;
cutting down glades and other similar works;
work to restore communication on the railway;
other.

Control is carried out using additional levers installed in the cab. Special hydraulics make it possible not to use excessive force when turning on/off the winch on the B10M.

Cost of ownership

The new B10M bulldozer, the price of which in the minimum basic configuration is no less than 3.7 million rubles (compare with the price of the T130), is beyond the means of many small construction companies or artisanal artisans. Therefore, there is a steady demand for its seasonal rental.

It is all the more justified because the cost of owning a car with a hydromechanical transmission, which has greater performance and lower fuel consumption, is significantly lower than one with similar technical characteristics, but representing a well-known foreign brand.

Modifications of the bulldozer B10M

At the moment, only two modifications of the bulldozer in question are common. One is standard, the second is used in conditions of high humidity, in swamps. They differ not only in appearance, but also in layout and chassis. These models are marked as follows:

B10M.0111-1E – standard basic modification;
B10MB.0121-2B4 – modification for work in swamps.

B10M.0111-1E has the following performance characteristics:

D-180 engine is installed;
transmission – mechanical;
number of skating rinks – 5;
the engine is started using a special starting motor - P-23U;
attachments installed at the rear of the chassis are used;
front attachment – hemispherical blade of class “E”.

Basic modification - B10M.0111-1E

The swamp modification has some significant differences, which relate primarily to the layout.

Model B10MB.0121-2B4 has the following features:

engine - YaMZ-326N-3 (a more powerful unit is required due to the use of equipment on soft soils);
transmission is only mechanical;
total number of track rollers – 7 pcs.;
the engine is started using an electric starter;
a pendulum tow hitch is always used at the rear;
in the front part there is a mounted straight fixed shaft without hydraulic distortion - type “B”.

Visually, the B10M modifications differ from each other only in the presence of attachments included in the basic package. The usual model B10MB.0121-2B4 looks like this:

Swamp modification - B10MB.0121-2B4

Models B10M2 and B10M.6100 are slightly more rare. Model B10M2 has the following distinctive features:

cabin with double glazed windows;
speed control is carried out automatically, directly by the transmission;
An impressive transmission resource is ensured by rolling bearings and DUO CON seals.

B10M2 looks like this:

A distinctive feature of the B10M.6100 bulldozer is the use of a unique hexagonal cabin. This is precisely its main advantage. Since this type of shape allows you to maximize the all-round visibility of the driver. Also worth mentioning are:

Sliding bearings are used - due to which the life of the running system is increased;
The inside of the cabin is covered with a thick layer of noise-absorbing materials, making work in it as comfortable as possible.

Bulldozer B10M.6100 looks like this:

You can often find models B10PMB.0121-1B4 and B10PM.0101-EN on sale. The first is used to perform various tasks in marshy areas. The second one is specially designed to perform tasks at training grounds.

Also, if necessary, through special sales representatives it will be possible to order various configurations of this type of equipment. It will be possible to choose the type of cabin to be installed and its heating system.

When choosing, special attention should be paid to the number of road wheels. The cross-country ability of a particular model directly depends on this.

Device

The design of the B10M bulldozer differs from the previous version by installing a higher power engine coupled with changed parameters of the fuel supply system.

To make the chassis last longer, seals are provided. They prevent oil from leaking out of the rollers. The track rollers located at the front are equipped with specific bearings. Some models provide an oil bath for braking and turning units. This innovation was called the “wet bridge,” which also made it possible to extend the operating time of the B10M bulldozer without the need for maintenance and repair. In addition, the maneuverability and reliability of the vehicle has become noticeably higher.

Operating experience of the B10M bulldozer. Advantages and disadvantages

The B10M bulldozer has been in operation for more than 10 years in a row. During all this time, all its main advantages and disadvantages have been identified. The number of positive aspects is many times greater than the negative ones. But it is the shortcomings that you should pay the closest attention to before purchasing. Today these include the following:

the D-180 type engine has a slightly shorter service life compared to a similar YaMZ one;
for stable operation without critical breakdowns, it is necessary to change all consumables on time;
In severe frost, hydraulic system hoses lose their elasticity and may burst - it is necessary to monitor their condition when working in the Far North.

Most often, problems arise with the servo drive of this type of bulldozer. Usually, oil begins to leak out from under the rod seal first. Moreover, in some cases, replacing the servo drive with a new one does not help. It would be possible to solve this kind of problem as follows:

replacing the rubber ring near the servo rod seal;
sometimes the diameter of the new oil seal on the rod will not match - earlier modifications had a smaller size (check the size with a bore gauge)
check the pressure in the return system - if there is foam in the oil, the breather is clogged

Servo drive removed from bulldozer

The following problems also often arise when operating this bulldozer:

low pressure level due to oil leakage from the hydraulic system through the seals;
For some reason, air enters the hydraulic system;
The hydraulic tank filter becomes clogged - this may result in swelling of the pipes.

Most problems can be avoided by timely replacement of filters, as well as other consumables. The most significant advantages include:

ease of operation and repair - spare parts can be purchased both new and on the secondary market;
low cost of repairs and the bulldozer itself;
a large number of additional, attachments;
the comfort of the driver’s cabin – its parameters comply with all current European standards.

Purpose

Special equipment is in demand at enterprises in the oil, gas, mining, and forestry industries. A bulldozer can often be found at construction sites or during land reclamation activities.

Without preliminary loosening, the device can cope with soils of categories I-III. The machine confidently works with sand, gravel, loam of any density or light clay.

When using a ripper, layer-by-layer digging of category IV soil (frozen soil of any composition) is possible. In addition, the machine is used when clearing snow debris - the maximum operating temperature is -50 °C.

Hydraulic system

Thanks to high-quality hydraulics, such equipment can operate under variable load conditions, reducing various power and dynamic loads in the transmission. The hydraulic system installed on the B10M is equipped with shock absorption, a balancing beam and a trolley, which is attached to three units. The units to which the hydraulic cylinders are fixed were moved forward, which had a positive effect on the speed of operations and reduced effort when lowering or lifting.
