Caterpillar D9R refers to the category of heavy bulldozers. This model He became a deep modernization of the classic Sat D9, which the company "Caterpillar" produces from the mid-1950s since the mid-1950s. The bulldozer won an impeccable reputation as powerful, reliable, productive specialist, characterized in the same low operational costs. This made SAT D9R one of the most common special machines in the world of this class (along with the Komatsu D275A bulldozer).

There are several different options and configurations, but usually a bulldozer of this model is produced with a removable grader and an attached rear-ripper of the soil. The robust design of the tractor and work equipment D9R is suitable for any, the most difficult working conditions. Specmark in a short time moves the huge volumes of soil and other materials, while maintaining the traditional "Caterpillar" technique, reliability and high profitability during large-scale work.

The main scope of applying the Caterpillar D9R bulldozer found in the mining industry and in the field of mineral mining. This special machine is also ideal for the implementation of large volumes of earthworks in careers, during the construction of roads and large-scale objects, on clearing and layout of the territories of large-scale construction sites; For the demolition of old buildings and structures, clearing the forest and extinguishing forest fires.

When working with soils of various categories, pre-looping is required only for the fourth category of soil. At first, this heavy bulldozer was not intended for wetlands or soils with high humidity. However, with the development and use of special wide tracks, it became possible.

The specific application of the CAT D9R bulldozer found in Israel's army. Since the 60s of the twentieth century, its armored version (first it was D9, subsequently D9R) was widely used to do the passes in the barriers and the destruction of the strengthened position of the enemy; Clearing the occupied territory from the ruins and debris and its demining.

In times of active hostilities with militant Islamist groups, armored bulldozers under direct enemy fire were evacuated with advanced damaged machines, armored transporters and tanks; Demanded homemade explosive devices and fugas.

Armored "Cat D9R".

Serious armor made a military version of Cat D9R invulnerable to explosive devices with power up to five hundred kilograms in TNT equivalent. And to protect the bulldozer from anti-tank grenade launchers, an anticoomulative screen "Sulamot" was developed.

Heavy specials were repeatedly used for direct travel through the houses engaged in terrorists, with the complete destruction of these buildings, the elimination of enemies and zero losses among their personnel. Militants "Hamaz" and "Hezbollah" on personal experience They made sure that no portable weapons, including RPG, cannot stop this bulldozer.

About the manufacturer of bulldozer - Caterpillar

Caterpillar is a giant transnational corporation, one of the world leaders in the production of construction and mining equipment, special equipment of engines and energy installations operating on diesel fuel and natural gas, as well as industrial turbines and diesel electrical locomotives. Under the brand name "Campillar" are manufactured by workwear and shoes, protected ("unhappy") cell phones and smartphones, and this is also our own company products. The Caterpillar Financial Services division also occupies the leading position in the market for leasing and lending to the acquisition of special equipment.

The vintage logo of the company was stylized under the creeping caterpillar.

In total, the firm is about five hundred divisions, in fifty countries of the world, on five continents. Headquarters is located in the United States. The firm leads its history since 1883, with the foundation by the Brothers Charles Henry and Benjamin Holt in California of the company for the production of agricultural machinery.

Under the Caterpillar brand (this word means "Caterpillar" in translation from English) The manufacturer's products from 1904, when the agricultural tractor received a large commercial success was released on the tracked year. Since 1931, the company began producing tractors and other techniques with diesel engines. The Second World War allowed "Caterpillar" to significantly strengthen and increase their strength: the company was able to take large state orders.

Nowadays, most of the SAT technique is produced at the factories you know what country. In the picture: SEM plant (Shandong Engineering Machinery) of one of the Chinese divisions of the company - Caterpillar Qingzhou (Qingzhou) Ltd.

The first foreign departments of Caterpillar became British (in 1950), Brazilian (1960) and Japanese (1963). The company received not only good glory, as a powerful growing transnational corporation, but also became informally known thanks to the record 17-month strike of Caterpillar workers, which began in 1994. In 2000, Caterpillar plant was built in the city of Tosno Leningrad Region. For several decades, all the company's equipment is sold under the SAT brand - abbreviated from Caterpillar.

Features of the Bulldozer Cat. D.9r.

This heavy bulldozer is very notice. However, its popularity in the whole world is determined by such advantages of specialists as highest reliability, strength and durability in operation. Play a positive role and such proven features of SAT D9R, as low care costs, small intake of diesel fuel and high resistance to aggressive media. The bulldozer is distinguished by large dimensions and high traction.

Naturally, to fully show top Qualities SAT D9R can only be loaded with impressive volumes. Therefore, this model preferences large construction companies and organizations.

The basis of the Bulldozer SAT D9R is a reliable carrier of the core, which does not transmit dynamic and other loads on the cabin cab. To enhance the strength, cast elements made of steel are envisaged, as well as spars made by rolling.

The main crankcase, the saddle of the balancing timber and the front crossing is reinforced cast steel parts, which are embedded in the most loaded areas of the main frame. This design well distributes the load and provides increased strength. The use of a box profile provides hard alignment of components. The top and bottom beams are made by the method of continuous rental, which guarantees the exceptional strength of the main frame.

Onboard gearboxes are installed at a considerable height due to the special design of the main crankcase. This location reduces their pollution, corroding and all sorts of mechanical damage, protects them from the effects of shock loads, abrasive wear and dirt. For the manufacture of the frame used is a closed rectangular profile.

The main frame of D9R is designed for serious shock loads and twisting efforts that inevitably occur when using a bulldozer dump and a soil ripper in heavy operating conditions.

The axis of swing and the bar for the balance of the hinge type is provided to optimize the position of the carrier structure in space, as well as to ensure the smoothness of the movement. For the correct operation of the mechanisms, their timely lubricant is necessary. It is performed through a single lubricant point, the connector of which is located to the left motor compartment. With this service, the lubrication of the fingers, end hinges, bearings and balancers is divided.

The stability of the equipment is ensured by the impressive weight of the Caterpillar D9R bulldozer. An important role is played here and the dump stabilizer, which enhancing maneuverability and effort of digging, as well as ensuring the balance of the bulldozer on any reasons. Thanks to the stabilizer, the installation of diagonal struts is removed. This is due to the transfer of lateral efforts directly to the carrying structure, but not on the moving parts and mechanisms.

Special fastening of the Tag-Link dust stabilizer moves a bulldozer dump to the tractor, which ensures exceptional maneuverability, the balance of specials and the high penetrating ability of the dump. This design also removes the need to install diagonal struts, since it transmits side loads to the main frame, and not on the pushing bars of the bulldozer dump.

Engine

Bulldozer SAT D9R is equipped with a Caterpillar 3408c turbocharged diesel engine (or 3408E, depending on the level of environmental requirements for the motor in the country where the technique is supplied). This is an eight-cylinder 18-liter power unit with a capacity of 354 kW (or 474 horsepower).

It has more than a solid margin on a torque, creating excellent rigging and efficient movement of heavy weights. SAT-3408 Motor Cylinder Block is made of gray cast iron, which has elevated stretchability resistance. This monolithic BC with four-glove heads is stabilized, which allows it to maintain internal dimensions under any working conditions. Engine cylinder diameter - 137 mm, piston stroke - 152 mm.

IN this engine The design with two intake and two outlet valves is implemented. Coatings are strengthened, designed specifically to ensure drafting. Rotary devices rotate valves approximately with degrees with each rise. It provides uniform wear and heat dissipation.

Valve rods are made of durable chrome steel and have good resistance both to wear and to strong thermal exposure. The crankshaft of the diesel engine is made of carbon steel. It is completely hardened, with an additional surface treated, and is balanced dynamically.

The standard configuration includes a motor electronic protection system when starting it in winter. Optionally, it is possible to install on the engine of the special HEUI system, which is used as a side computer. With this equipment, the mechanic can monitor the state of the specialist at any time.

This diesel is fully complied with current exhaust quality requirements (EU, EPA, JMOC). A minor amount of smoke during the operation of the motor is ensured by optimizing the flow of diesel fuel and electronic setting of operation modes.

A two-way engine cooling system provides a cooling fluid circulation from the bottom tank with sections up on one side of the cooling element, and then down through the second side back to the bottom tank. The inner outer cooling regiment of the engine increases the coolant flow to the top of the cylinders, which provides a longer service life of the cylinder and piston. The design with an increased depth of the piston skirt and internal fins ensures the strength and rigidity of the cylinder block.

Cooling elements are made in the form of separate cores connected to the lower Baku separated by the section. The design does not include the upper removable tank. The use of nine standard steel edges in an inch protects against system clogging. Increased reliability is ensured by using brass tubes in each radiator.

There are additional radiators configurations in stock - to work with high temperatures and / or with a large degree of wear. To reduce the risk of leakage, brass tubes are welded to a massive collector housing, which makes the strength of the connection of the tubes and a collector elevated. The capacity of the engine cooling system is 125 liters.

The service has the opportunity to produce, directly without folding the roar of the radiator. Each core module can be replaced separately (without dismantling the entire radiator). This largely reduces costs and repair time.

In general, based on a rich operation experience, manufacturers have tried to provide simplicity and ease of maintenance and repair even when working in remote regions, where it may not be found access to diagnostic devices.

If there is a large amount of abrasive materials in the surrounding air, the additional fan of the coating and dust grille is used to minimize the radiator damage.

Large endurance, resistance to loads and the durability of the engine SAT-3408 was repeatedly confirmed in real conditions When performing all types of work. Reliability power aggregate Conducted by I. comprehensive work PPC, with the possibility of control under load and the torque divider.

Transmission cat. D.9r.

The planetary gearbox of the SAT D9R bulldozer has three speeds in the front and as much - in the rear directions. A similar design allows a large number of gears to make a load, while it is transmitted to bridges. And in the gearbox with an intermediate shaft, the load is transmitted only to one gear.

Scoop and spiral conical transmissions significantly reduce the level of noise load on the operator, through its design, structure and location. These gears are in the back Carter of Specials.

In the transmission, large clutch-cooled clutches are provided, effectively absorbing directional energy to ensure the smoothness of work and increase the comfort of the mechanizer. The patented special machine for making the "F37" clutch extends its service life, especially when working with intensive maneuvering, and guarantees the maximum productivity of the machine. Compared with traditional materials, this also minimizes pollution transmission Oil.

The collection of transmission oil is separated from both onboard gear reservoirs to prevent contamination in the event of a refusal of any of the systems. This allows the use of modular components to substantial extension of work time during the entire service life of the bulldozer.

The convenience of servicing the gearbox is thought out. Its modular layout greatly simplifies the dismantling / installation process. The conical gears and gears are made with a high degree of accuracy, and there is no need to form kits from them. This reduces repair costs.

To increase the efficiency of the power transmission and the torque increase coefficient, a single-stage transformer with a torque divider at the output transmits 75 percent of the engine torque through the torque converter, and the remaining 25 percent is directly through the drive shaft. Transfer case Provides serious efficiency and an extended range of applying a second transmission when the bulldozer and the use of a knife is used.

The dispensing box protects the transmission from high loads due to sharp changes in torque and vibrations. The effectiveness of the torque divider increases with the help of the stator of the free stroke mechanism. When working in small loads on the coupling device, it is permissible to rotate the reactor to achieve peak efficiency. As a result, heating decreases and an increase in fuel efficiency.

To increase the traction effort and ensuring the smoothness of the motion of the bulldozer, raised leading wheels and a complete suspension of the chassis are intended. And dynamic effects are absorbed by the supporting structure; On-board gearboxes, bridges and control system remain unsuccessful mechanical effects.

The verified trolley design contributes to a pressure reduction on a base of 15 percent, compared with the previous modification, and also eliminates the ribbon slip, ensuring a rational distribution of the bulldozer mass and the smoothness of the movement. Rollers are mounted on carrier tubular frames, and it does not give them any possibility to twist or bend. At maximum stress points, an additional reinforcement is also provided.

The protection of guide rinks is needed to reduce the number of aggressive substances that fall into the running part, as well as to reduce the degree and speed of wear. It is equipped with special rubber liners. In the heading guides there is a shield that provides additional protection against wear by influence of abrasive materials on the running part.

Crawler ribbons are sealed, lubricated, with a forced finger fastening system (PPR). They were specifically designed for use when working, which is associated with strong impacts and consistently high loads. The verified PPR design fixes the link on the finger, reduces the possibility of premature loss lubricant. The hermetic design consistently covers the finger of the caterpillars with a lubricant, reducing the metal contact with the metal and excluding the wear of the inner parts of the finger and the liner.

The width of the shoe is 610 mm. Number of shoes for side - 43 pcs. The step of the tracked chain is 240 mm. Contact area with soil - 4.24 sq.m. The number of support rollers to the side - 8 pcs.

Maximum power of DVS Develops at 1800-2200 rpm, and low fuel consumption allows continuously to operate the technique for 16 hours.

Rama D6R is designed to overcome a large twisting moment and impact efforts. For the manufacture of the most loaded elements, forging is used, it increases the durability of the entire design.

The automatic 4-speed gearbox, which has a planetary design, corresponds to the torque transmission. It provides a quick and smooth shift of gear under load and reduces fuel consumption. The tractor control is carried out using a differential system with hydraulic drive. Due to this, the operator can be comfortable, without applying efforts, control the turns and direction of movement at the same time.

D6P is equipped with a straight bump (4.3 m³) and a gear ripper.

Bulldozer Caterpillar D9R.

Due to the large size and reliability, a heavy bulldozer Caterpileler D9R is in demand among major construction companies. It is equipped with a 9s grader (16.5 m³) or 9su (13.5 m³) and a removable gear ripper.

Special modifications of D9R are in service with the United States and Israel. They are used for demining and evacuation. The tractor is equipped with additional reservations (15 tons) and cumulative SULAMOT screen. Durable design military equipment Cat is able to withstand an explosion, the TNT equivalent of which is 500 kg.

Specifications CAT D9R

The high reliability of the 18-liter engine is provided by the pig-iron engine block, the tempered crankshaft from carbon steel and the cooling system is supplemented by the inner upper shelf. Fuel is supplied through a hydraulic injector pump, and the mechanical control system allows maintenance and repair without diagnostic devices in any terrain.

To increase the efficiency and engine resource, a torque divider is used. Only ¼ power is transmitted directly through the shaft, the remaining 75% through the torque converter. For effective torque division, the free movement is installed, it allows you to save fuel and reduces heating at low load.

A planetary 3-speed gearbox operating in both directions is installed on D9R. Transmission clutches are made of patented F37 material and have oily cooling. In the turning mechanism apply onboard friction and brakes. This design provides good maneuverability and easy control of a 50-ton bulldozer.

High strength frame made of box profile. In the parts that are subjected to the greatest loads, cast steel parts are embedded. Dumping attached to the frame with the TAG-LINK stabilizer.

The chassis design made it possible to raise the drive wheels and install the complete suspension of the chassis, which ensures the smoothness of the stroke, and the shock loads from the equipment are transmitted to the main frame. This increases the service life of bridges and gearboxes.

For maximum protection against adverse conditions, caterpillar ribbons and rollers have a hermetic design, which prevents premature washout of lubrication.

The tractor cabin has panoramic windows that provide maximum overview when maneuvering. The cabin has air conditioning, radio tape recorder and adjustable driver's seat with back and hips. On the dashboard Displays information about the state of the bulldozer systems: the temperature of all technical fluids and intake manifold, fuel level, engine speed, oil pressure and coolant, degree of filter contamination, etc.

All tractor elements are made in the form of modular systems, which facilitates maintenance.

The universal dump 9U has a box-made design that provides high twisting resistance. If it is necessary, 9SU is used or for work with high density materials, which has a smaller volume, but increased strength. If necessary, it is possible to install a dual skew system.

Bulldozer Caterpillar D11T.

The largest bulldozer boilerpiller d 11 is used in the mining industry. Its length with the blade (27.2-63.46 m³) and the ripper exceeds 10 m. Despite large dimensions, the tractor control is carried out without effort, and maximum speed It is 12-14 km / h. Promote this system similar models D9.

Specifications CAT D11

Advantages and disadvantages

During its existence, CAT has proven the reliability of wheel and tracked technology. The device of bulldozers the boaterpiller is considered to be exemplary. When they are manufactured, it is used: frame, power transmission and an engine of its own production. Caterpillar machines are capable of operating at an altitude of more than 3000 m, at low temperatures and on a wet soil. The design provides convenience when carrying out maintenance and repair.

Thanks to a large dealer network and a well-thought out plan for warranty service, it is possible to obtain technical support in any part of the world.

Campiller provides a large selection of hinged equipment adapted to the device of bulldozers.

The only drawback of CAT technology is the big initial value, but due to the efficiency and reliability, operational costs are reduced.

Price and review of owners

The cost of the excavator will depend on the selected configuration. In the CIS area, the average price for D6R is $ 352,000, and on D9R - $ 99 billion.

We use CATERPILLAR D6R LGP 2007, the operation of 15200 m / h. Powerful and reliable bulldozer. The service was conducted by CAT specialists. Service and appliances are satisfied.

Ilya, Vladivostok

Since 2008, more than 24,000 m / h were developed on D6G. The tractor is in good working condition. Comfortable and easy to manage, the operators quickly mastered the technique.

Analogs

According to D6 characteristics, you can compare with the CHTD-170. Products of the Chelyabinsk Tractor Plant is cheaper, but is inferior in reliability, and the productivity of D6P is three times higher. An analogue of CAT D11 is considered a small T-800, which is also inferior in the effectiveness of the American bulldozer.

The main competitor CATERPILLAR is the Japanese engineering company Komatsu Limited. Their products have good indicators reliability and wear resistance. The model range of bulldozers consists of 11 types of equipment from 8 to 103 tons.

For a long time in Russia did not bring a brighter and colorful car - the rapid streamlined silhouette, the "mirror" band of the front optics, short skes behind and in front ... car Honda Civic. Causes associations with space fighter from "Star Wars". Usually, at the end of the automotive exhibitions, the bright concept of fading "under the influence of marketing realities", but with the 5-door Honda Civic did not happen.

The car is rich in many such little things that attract the glance and create a mood. For example, triangular silencer holes and similar shape fog lights, and the handle of the rear doors are embedded like in Alfa Romeo. 156, the front is made in the form of ahead of the arrows. Honda Civic gas tank cover (it's a pity that it is plastic) decorated for sports. On the back door, again in the sports style, there is an anti-cycle, which improves high speed stability, but a worsening overview. Maybe it's with a hint that the driver of futuristic Honda Civic is no reason to look back.

But surprise is able to call not only exterior appearance Honda Civic hatchback, if you look inside ... delight will be no less. In the hands of the driver, it is convenient for a 3-spoke steering wheel, which has a "right" size, thickens in the zones of grip and, again, the original design. The left of it is located the engine start button and the stove deflector. On the right (symmetrically left tools) placed temperature control and intensity controls. The tachometer is located directly in the center of the dashboard, and on its sides there are indicators of the level of gasoline and the temperature of the coolant. The speed is reflected in the Speedometer LCD panel, just above the tachometer.

Front, in Honda Civic, the bucket seats are installed with excellent side support and an anatomical profile. For the feet of the driver and the front passenger there is a mass of free space. No less spacious and rear. This is amazing, but Honda Civic is one of the leaders in the classroom at the trunk capacity - as much as 415 l!

Move the engine key is not interesting ... And in Honda Civic is also impossible. To do this, the "Start Engine" button is provided in the car. The key is only needed in order to turn on the ignition. After that, click the button.

With sound insulation at Honda Civic in moderation - pleasant notes 1.8-liter Hondovsky motor are heard, but not immediately calm down, so as not to disturb those who are waiting for the comfort of comfort and silence. A 140-strong engine Honda. Civic - RED, traditionally, turn around, rumored and pleasantly excites the vestibular apparatus.
The mechanical 6-speed box allows you to accelerate up to a hundred on the integer 2 with faster than with it robotic option. Automatic box In the Honda Civic hatchbacks will not be, but in the convenience of the "robot" in what he is inferior to him.

The Honda Civic wagon-poured steering wheel, sharply transmitting teams wheels, causes instant addiction - this is true driving pleasure. Direct segments of the road want to avoid, and the eyes involuntarily open turns and goals for overtaking and rebuildings. Low ground clearance, sufficiently rigid suspension, 17-inch wheels with low-profile tires are associated with a single almost racing tool that can satisfy a lot of driver ambitions. Honda Civic is an extremely acute car in control, devoid of rolls in turns, challenge next in a given direction. For these advantages, it is necessary to pay the lack of comfort on a broken road, and so, unfortunately, in Russia there is still plenty.

Two pairs disc brakes Honda Civic is extremely effective, and the participation of electronic subsidiary systems occurs unnoticed, as if they are not, and you will cope with the situation. Fully self-confident drivers will delight the opportunity to completely switch Honda Civic under its control: System currency stability VSA is completely disconnected by one click of the button.

Honda Civic 5D is good almost in all - appearance, opportunities for aggressive driving on the highest level... Effect and effective. And people are ordered mainly sedan. Why?
Well, the first is a serious reason is the price. The starting price of the Honda Civic hatchback at $ 5,000 higher than behind the sedan. Not everyone is ready to pay this money, mostly for appearance and pronounced sports style.
The second reason is character. The fact is that tougher settings, rear twisted beam, smaller clearance and low-profile tires, negatively affecting comfort. It would seem why comfort is the same sports civic? But in the sedan, the acuity of control is preserved with a decent level of comfort.
