Models of a powerful agricultural tractor. "Kirovtsi": technical characteristics, photo

The Kirovets Mark has already been more than 50 years old. Without any exaggeration, it can be argued that this brand is known on all continents of the planet. 90 years of experience in tractor construction allow the Kirov Plant (St. Petersburg) to successfully compete with the world leaders of the industry. And today the tractors of the brand "Kirovets" find their niche in the national economy.

Description

Kirovsky Zavod is a diversified holding company, one of the most important areas of which is the design and production of wheeled energy-saturated tractors of the Kirovets brand. For this, the unit of CJSC "Petersburg TZ" is responsible.

The enterprise is one of the pioneers of domestic engineering. The first serial licensed tractors "Fordzon-Putilovets" were produced in 1924. However, the brand tractors Kirovtsy K-700 have been produced since 1962.

The lineup

The modern model range includes agricultural, construction-utility and special equipment of the K-744 P series of various designs with a capacity of 300, 306, 350, 354, 390, 401, 420, 428 liters. from. The most powerful are the Kirovets K-9000 tractors: the K-9520 modification boasts 516 horsepower. Unlike Soviet times, vehicles have a modular layout with a wide range of engines produced in Russia, Germany, the United States, a large range of attachments, additional options.

The most popular product of the Petersburg tractor plant in the domestic market is the Kirovets tractor K-744 P2. He has an optimal ratio of technical characteristics for the average farm, communal and construction organizations.

Basic parameters of the vehicle as standard:

Tractors "Kirovtsy" in the premium package:

New level of comfort

In new models, manufacturers have made the operator's workplace comfortable, comfortable and safe. During intense periods of field work, the cab becomes almost the home of a tractor driver, where he spends 10-12 hours a day. To protect people from noise and vibration help modern materials and technical solutions used by St. Petersburg designers. Sealed cabin is installed on cushioning cushions, the cabin metal is covered with modern vibration-absorbing and sound-insulating materials.

Fieldwork often falls on hot in the most direct sense periods - often the ambient temperature outside the tractor reaches +40 ° C. And it can also be the other way around when a cold winter in winter only a Kirovets tractor can clear snow blocks or carry a heavy load. Therefore, factory workers install a powerful air conditioner and an efficient heating system for all K-744 P series cars.

Control

Tractors "Kirovtsy" are managed very easily - without physical effort. Ergonomics of the workplace meets modern requirements. The sprung operator's seat is located in the center of the cabin, from which an excellent view in all directions is opened, which is very important for fieldwork and maneuvering.

To facilitate the management of the transmission, a pneumatic mode switching system and a rear axle connection are installed (optional option available). The driver's seat has a wide range of adjustments - height, longitudinal position, operator weight. Also, the steering column is adjustable in height and inclination. This allows the mechanic of any complex to find the optimal position for himself at the wheel. Assistant mechanic or instructor will be accommodated in the cabin on an additional passenger seat. Like the driver's seat, the passenger seat is equipped with seat belts.

The operator can easily control the parameters of the tractor with a set of instruments and control lamps on the central panel. All vehicles of the K-774 P series are trained to install GPS / GLONASS satellite monitoring systems.

Security

Tractor "Kirovets" from the security point of view is protected in all respects. It is a stable machine with an effective braking system and reliable control. But even if the tragic accident happened and the tractor capsized, the person will securely protect the security cage built in the cab, which meets the international ROPS / FOPS standards.

At the peak of the field work season, roads are every hour, and darkness should not be a hindrance to work. Four main and eight working headlights perfectly illuminate the working area along the perimeter of the tractor "Kirovets".

Engine specifications

The manufacturer offers the consumer a choice. Depending on the production tasks and preferences, it is possible to choose a machine from a wide power range - from 300 to 428 liters. from. For each power level there is a variant with a domestic and foreign motor.

Equipped with turbo-supercharged diesel engines, namely to this type of engines are "Kirovtsev", characterized by excellent efficient and economic indicators. An important feature of the applied power units is the high torque at rated power.

To increase the reliability and increase the life of engines from 2014, tractors "Kirovtsy" are equipped with new air filters of improved design. Thanks to a two-stage combined air purification system and a high air intake, the engines are reliably protected in a highly dusty environment. The replaceable filter elements are easily accessible for purging and replacement.

Reliable cooling is of fundamental importance for tractor engines operating under tension. Since 2014, the most powerful modifications are completed with a new block of radiators with an enlarged water section.

Motor brands used:

• Avtodizel (Yaroslavl): model YaMZ-238ND5 (300 hp).
• "Tutaevsky MZ" (Yaroslavl region): series ТМЗ 8481.10 (350, 390, 420 hp).
• Daimler AG (Germany): series OM 457 LA (354, 401, 428 hp).
• Cummins Inc (USA): model 6LTA 8.9 (306 hp).

Fuel system

Fuel systems of domestic diesel engines - mechanical. They are quite simple in design and well adapted to our fuel. For Mercedes-Benz engines equipped with more advanced electronic fuel delivery systems , additional filters are included in the system, and the nozzles are adapted to Russian fuel by German specialists.

To start engines at negative temperatures, preheating systems are used, therefore the operation of Kirovets tractors in winter is not particularly difficult. 800 liters of fuel holds a fuel tank located on the rear of the half-frame - this is a good fuel reserve for the longest working shift.

Thrust

Tractors "Kirovtsy" are often exploited in harsh conditions. Serious loads are transmitted to all elements of the transmission and the chassis. That is why the requirements for them are special. Transmission "St. Petersburg giant" mechanical, with hydraulic control. Its speed range (16 forward / 8 reverse) consists of 4 ranges of 4 transmissions in each. Within the range, the transmissions are switched on-the-go without interruption of the power flow.

A characteristic feature of the leading bridges of Kirovtsa are the self-locking differentials of the "know-spin" type, which allow to provide unsurpassed patency in difficult conditions. Planetary gearboxes, spaced along the sides, transmit the torque directly to the wheels. The advantages of such a scheme are increased ground clearance and excellent accessibility for maintenance and repair.

Reliable transmission of high torque is guaranteed by production technology. Gear gears and bridges are manufactured according to the increased accuracy class. Sulfocyanated disks made of high-carbon steel are used for the clutch of the drive shaft of the gearbox.

Driving performance

Unsurpassed cross-country ability is possessed by the tractor "Kirovets". The photo of this "strongman" impresses with its size, power, and modern design. With its considerable dimensions, it has good maneuverability, which is facilitated by the innovative design of its frame - the two half-frames are connected by a hinge device. They are able to rotate about a vertical hinge at an angle of 35 °, thanks to this turning radius is less than 8 meters (on the outer wheel). With respect to the horizontal hinge, the half-frames are displaced by 16 ° - "Kirovets" perfectly copies the relief of the soil, due to this, all the wheels are permanently attached to the supporting surface.

Every machine operator who has worked at Kirovets, always notices his special smooth running. The suspension suspension of the submerged bridge - that's what gives such a wonderful effect. For many foreign analogues, the sprung bridge is not available or is an expensive option, and for the St. Petersburg tractor this is the basic equipment.

Aggregation

Increase the traction and reduce the specific load on the soil with the help of sets of twin wheels supplied as additional equipment. The use of twin wheels is required on wetland soils. Optimize the weighting of the tractor and improve the grip of the wheels with the soil can be using dial-up ballast weights placed on the cargo and sub-engine half-frames. This option is given to the model of the tractor "Kirovets" K-744 P3, as well as K-744 P4.

The value of the tractor lies in the possibility of its use with a complex of machines. The standards of coupling devices, hydraulic requirements, electricians, pneumatics and other parameters of trailed equipment may differ. Aggregated with machines, the technique is being improved, the most important criterion is the universality of coupling devices and a stock of hydraulic performance.

The hydraulic system of Kirovets tractors' equipment refers to the type "load-sensitive", it can be designated as LS-system or Load Sensing. An axial-piston pump with automatic flow control pumps the working fluid only when the attachments are working. Its peak output is 180 l / min.

The hinged three-point device (IV category) gives a lifting capacity of 8.5 tons on the suspension axis. It is noteworthy that it initially comes as standard. To simplify the assembly with any domestic and foreign agricultural equipment, tractors are equipped with automatic hooks of lower links manufactured by Walterscheid.

Additional options

According to a special order of the tractor "Kirovtsy" can be equipped with the system of position control of the attached device (EHR), which is necessary for working with plows and other attachments that do not have supporting adjusting wheels. Also as an optional equipment, the machines are equipped with a power take-off mechanism (shaft rotation corresponds to 1000 rpm) and a pendulum trailing device.
