Kamaz 6520 technical characteristics fuel consumption

In 2007, the Kama Automobile Plant began producing the KamAZ-6520 heavy-duty dump truck. This 6x4 truck is capable of transporting up to 20 tons of cargo with a total volume of 12 m3 in a standard body configuration or up to 20 m3 in a configuration with an increased side. The design of the dump truck widely uses foreign-made components: engine, transmission, injection pump and a number of others, which increases its reliability and efficiency. There are several modifications that differ in engine power and type of cargo platform.

Description

The model allows the plant to maintain its first position in the automotive market of Russia and the CIS. This heavy-duty dump truck has been considered the first from the Kama manufacturer for over ten years. Today it is widely used in construction and is used for large-scale quarrying and agricultural work.

Its development was dictated by necessity, since since the beginning of the two thousandth the existing KamAZ 55111 and KamAZ 65115 models, whose carrying capacity was thirteen and fifteen tons, were not enough to meet the increased needs of the construction industry.

Serial production began in 2003. It is interesting that at this time many cars had already undergone restyling, in which they received comfortable cabins. However, the new truck was produced with an outdated cab until 2007, after which it was replaced. Therefore, today the cabin is not inferior in comfort to other cars of the automaker.

The service life of KamAZ before overhaul is 500 thousand kilometers. The first maintenance is carried out after five and a half thousand kilometers, and the second after sixteen and a half thousand kilometers.

Since KamAZ became the first model in a long period of time, new trucks were also developed on its basis. The first four-axle trucks in Russia were produced - KamAZ 6540 dump trucks with an additional axle (8*4 wheel arrangement), which are capable of transporting cargo weighing up to 18.5 tons. Another similar four-axle truck, KamAZ 65201, transports up to 25 tons. These vehicles are especially needed where there are restrictions on axle load.

For quarries and off-road use, a modification (6*6) KamAZ 6522 is produced, with a carrying capacity of up to 19 tons. A number of modifications that differ in certain capabilities include the following cars.

Fuel consumption standards for vehicles with KAMAZ-740 engines (Euro-2, -3, -4)

Specifications

KamAZ 6520 is distinguished by technical characteristics, the main ones of which are as follows.

• length from 7,710 to 7,800 mm;
• width 2,500 mm;
• height 3,010 mm.

• curb weight 12,950 kg;
• total weight 33,100 kg;
• load capacity 20,000 kg.

• in summer when loaded – 45 l;
• in winter - up to 53 l.

Considering the load capacity of the dump truck, the technical characteristics regarding fuel consumption are quite economical. However, foreign analogues can boast better results in this regard. The manufacturer's data on average fuel consumption agrees with driver reviews. But you should also take into account the conditions in which the vehicle is operated, as well as the driving style of the motorist.

Naturally, in traffic jams in the city, and even more so off-road, the truck will consume more fuel than under standard conditions.

model KamAZ-740.51-320 (Euro-2), or turbocharged Cummins ISLe (Euro-4), or KamAZ 740-73-400 (Euro-4);

• type – diesel unit with turbocharging;
• power – 320 l. pp., 334 or 400 on different models;
• cylinders – 8, V-shaped arrangement;
• volume 11.76 liters (if a KamAZ engine is installed).

With these characteristics, the car reaches speeds of up to 90 km/h.

At first, the trucks were equipped with KamAZ-740.51-320 diesel engines with turbocharging. They were developed back in the nineties and were equipped with other cars. But since 2009, they began to be equipped with KamAZ-740.63-400 Euro-4 standard. The engine is also turbocharged. It features better performance compared to the earlier version.

Among other things, some dump trucks began to be equipped with even more productive Cummins ISLe +350 units. Their power is 334 horsepower with a volume of 8.9 liters and a torque of 2738 Nm.

Consumption at idle speed

To determine fuel consumption at idle, it is necessary to divide the engine displacement by 2. Thus, a 6.7 liter engine will consume 3.3 liters per hour at idle, while for a 10.8 liter engine this figure reaches 5.5 liters . For a 12 liter Mercedes-Benz engine, the idle consumption is 6 liters per hour.

There is another way to determine fuel consumption at idle in one hour. To do this, you need to subtract 10% from the official average consumption. It is important to keep in mind that this method is best used in winter operating conditions.

Design Features

To provide better lifting capacity, strength and achieve economy, the machine must be equipped with a new hydraulic system, a reinforced frame and various components.

KamAZ 6520 is equipped as standard with a metal cargo platform with an unloading mechanism at the rear. This dump truck has the main technical characteristics of the body that it is located on a reinforced frame, and strong hydraulics driven by the power take-off allow it to lift heavy loads. Due to the extension sides, the load increases significantly.

The welded platform is characterized by increased reliability in terms of technical characteristics and body volume. Control is implemented directly from the driver's cabin. The platform has an oval or rectangular cross-section:

• the oval version provides better rigidity and reduces load sticking;
• The rectangular version is suitable for larger cargo volumes when significant capacity is required.

The drive axles are designed as follows. The main gearbox is supplemented with Bulgarian planetary gears. Cardan shafts and suspensions are quite resistant to various types of loads. Drive axles with a single-stage main gear and gearboxes, on the one hand, increase the clearance of the axle, and on the other hand, increase the strength of the axles, which plays a special role when the dump truck operates with an overload (although this is undesirable).

The KamAZ's cross-country ability is significantly increased by blocking cross-axle differentials. Thanks to this, the car can be used off-road.

It is convenient to indicate the characteristics of the braking system in the following table.

KAMAZ body – options for any needs

The KAMAZ 6520 body has several options that differ in shape, type of unloading and volume, which allows the consumer to choose the dump truck configuration necessary to best meet his needs.

This versatility also determines the very wide scope of application of the KAMAZ 6520 dump truck in industrial, road and civil construction and mining.

Undoubtedly, the popularity of this model and the stable demand for it are the best confirmation that KAMAZ engineers once again coped well with all the assigned tasks.

KamAZ-6520: modern heavy-duty dump truck

Due to the rapid development of the construction industry, the need for heavy-duty dump trucks has increased. The Kama Automobile Plant began developing such a car, the first copies of which rolled off the assembly line in 2003. Since then, KamAZ-6520 has remained a leader in the heavy dump truck segment; the vehicle is in demand and is still in production today. In addition to the construction industry, the truck is often used as a timber carrier, grain carrier, KDM (combined road vehicles), concrete mixer trucks are installed on the chassis, truck cranes are mounted, and other manipulators.

Power unit and fuel consumption of the KamAZ-6520 heavy-duty dump truck

The debut modifications of the truck were driven by a KamAZ-740.51-320 V-shaped diesel engine (Euro 2), equipped with a turbocharging and intercooling system for charge air. The engine had a displacement of 11.76 liters and a rated power of 320 horsepower. At that time, most heavy KamAZ vehicles were equipped with this power unit. However, the engine was not very economical, as a result of which it was replaced by more modern turbodiesels.

Cummins ISLe +350 . Modern six-cylinder turbodiesel with in-line cylinder arrangement. The engine has a displacement of 8.9 liters and a rated power of 334 horsepower. The engine is equipped with a Common Rail fuel system and an HX40 turbocharger with an adjustable exhaust tract. We also note the presence of air intercooling technology, which reduces emissions of harmful substances into the atmosphere. The Cummins ISLe +350 engine meets Euro 4 standards.

KamAZ 740.63-400. This power unit complies with Euro 3 standards, it has a displacement of 11.76 liters and develops a rated power of 400 hp at a crankshaft speed of 1,900 rpm. Structurally, the engine is a V-shaped “eight” with a turbine and an intercooling system for charge air.

The dump truck is equipped with a fuel tank of 500 liters, sometimes an additional tank with a filling capacity of 350 liters is installed. Fuel consumption depends on operating conditions and engine. KamAZ-6520, equipped with a domestic engine, consumes up to 45 liters of fuel in the summer; in winter, consumption rates increase by 7-10 liters. Cummins ISLe +350 engines are more economical and consume 12-15% less diesel fuel than domestic counterparts.

Transmission, power supply KamAZ-6520

Even the pre-restyling versions of the KamAZ-6520 dump truck were equipped with a modern ZF-8S1820 gearbox manufactured by Zahnrad Fabrik. This eight-speed manual transmission ensured comfortable operation of the car and was highly reliable.

Today, the bulk of KamAZ-6520 vehicles are equipped with a 16-speed manual transmission ZF 16S1820. The transmission consists of a main four-speed gearbox with a divider and range. The advantages of this box include low noise levels, ease of gear shifting and the ability to use a ZF intarader (secondary retarder). The interaction of the engine with the gearbox is carried out using a single-disc diaphragm clutch with a hydraulic booster and a pneumatic drive.

The car's electronic and electrical systems are powered by two 12-volt batteries with a capacity of 190 A/h. A voltage regulator is installed in the driver's cab, and the truck is also equipped with a powerful two-kilowatt 28-volt generator.

Brakes and suspension KamAZ-6520

Like most vehicles from the Kama plant, the KamAZ-6520 is equipped with drum-type brakes with energy accumulators, which provide acceptable safety when driving on public roads. The diameter of the brake drum is 400 millimeters, the width of the brake pads is 180 mm. In addition to the main brake system, the truck is equipped with a spare, parking and auxiliary brake. Even the first versions of the KamAZ-6520 were equipped with the ABC anti-lock braking system, which avoids wheel locking during emergency braking.

The front suspension of the car is made in a combination of semi-elliptical longitudinal springs and hydraulic shock absorbers. In addition, a stabilizer bar is installed here, which prevents the car from dangerously rolling. The rear part of the suspension is made in a similar style; semi-elliptical springs are also used here, and a transverse stabilizer is installed to increase angular stability.

Detailed technical and operational characteristics of the KamAZ-6520 heavy-duty dump truck are given here:

A little history

The first Soviet dump truck appeared shortly after the American one, it was developed by engineers of the Moscow Automobile Society (AMO), later renamed the Plant Named after Stalin (ZIS), and then the Plant named after Likhachev (ZIL), whose name, along with its maiden name, is this plant still wears it today (AMO ZIL). The dump truck was called ZIS-5 and, created on the basis of the famous and popular “three-ton” truck of that time, the AMO-3 truck, it was produced in a variety of modifications and incarnations for more than thirty years.

Of course, “three-ton” is not a scale for a real dump truck. Already in the 40s in Soviet Belarus, the Minsk Automobile Plant (MAZ) began production of the heavy MAZ-205 mining dump truck, which could carry 6 tons of cargo almost off-road. A little later in Soviet Ukraine, at the Kremenchug Automobile Plant (KrAZ) it was already built The domestic “miracle of technology” is the KrAZ-222 mining dump truck with a load capacity of 12 tons.

On our website you will find many articles devoted to both individual KamAZ models and general information about the equipment of the Kamaz concern. After reading this article, you will find out how much cargo fits in the body of a Kamaz.

A review of KamAZ prices will also help you make your choice.

Birth of Kamaz

Both MAZ and KrAZ, for all their advantages, had one common drawback - they were not so much cars as “steel monsters” (KrAZ generally did not fit into our standard roads in terms of dimensions). It was very difficult to imagine them anywhere other than a quarry (for example, on a city street), and the “three-ton” ZIS was hopelessly outdated by the early 70s.

KamAZ 53121

In addition, in the early 70s, the most modern (by then standards) truck production plant, KamAZ, was built in the city of Naberezhnye Chelny. And then, almost simultaneously with the first model - the KAMAZ 5320 flatbed truck - the KAMAZ 53121 dump truck was launched into production. This vehicle was somewhat inferior to the KrAZ in terms of carrying capacity (10 tons instead of 12), but was no longer so “brutal” and, most importantly, had total weight no more than 18 tons and fuel consumption no more than 30 liters per 100 kilometers.

Ten years later, a new version appeared, KAMAZ 55111, with slightly reduced dimensions while maintaining the same load capacity. From 2007 to the present day, the Kama plant has been producing the KAMAZ 6520 vehicle, which, with its own weight of 12 tons, is capable of transporting 20 tons of cargo, and in its dimensions it fits perfectly into the acceptable dimensions characteristic of its predecessors in the KAMAZ family.

Transition to the market

Of course, the appearance of this vehicle at the turn of the nineties and zeros was, first of all, an effective response to the market needs for new vehicles with increased payload capacity, and it was KAMAZ 6520, 20 ton, that became the first representative of the heavy class of dump trucks in the model range of the Kama plant. has been holding a leading position for a whole decade now and has not lost its popularity and demand.

Undoubtedly, KAMAZ always produced very high-quality products, but by the end of the century its dump trucks began to succumb to competition with the products of the world's leading manufacturers, in some ways seriously lagging behind them in technical characteristics.

For example, the already mentioned KAMAZ 55111, which had worked perfectly for the previous two decades, had a load capacity of 10 tons, which in the new conditions was already insufficient.

New race

Although some basic design elements - a reinforced welded frame, an anti-lock braking system, controls in the driver's cabin - were worked out on previous models, the KAMAZ 6520 contains a lot of new things.

KamAZ 6520

All components of this model are capable of withstanding the most severe operating conditions, and in general it must be said that the KAMAZ 6520 is not even a modernization of previously produced dump trucks, but the first-born of a completely new, promising direction of work for the engineers of the Kama Automobile Plant.

Review of the KamAZ-6520 dump truck and its multifunctional modifications

KamAZ-6520 is a truck that is designed for transporting bulk construction, industrial and agricultural materials along roads with a permissible throughput of up to 13 tons and complete off-road conditions. The car was created by the Kama Automobile Plant.

The dump truck is popular among enterprises whose activities are directly related to loading and unloading operations and transportation of goods. It can cope with any tasks, therefore for 10 years it has occupied a leading position in the model line of domestic trucks and fully satisfies the demand and needs of modern companies operating specialized equipment.

Device

The structure of the truck can be represented as follows:

• frame;
• body;
• cabin;
• power transmission;
• engine;
• air system;
• brake system;
• electrical equipment;
• fuel mechanism;
• oil tank.

The manufacturer is constantly improving and modernizing the design of the machine. After restyling in 2009, the tonneau is equipped with a more environmentally friendly diesel engine, better hydraulics and a reinforced base. The cabin has a high top, an original buffer and a lower belt. Comfortable seats, climate control systems and the latest instrument panels are installed. There are sleeping places that were previously absent. A new U-shaped radiator grille and side headlights have been developed, and the dimensions of the bumper have been increased.

A heating system using exhaust gases is installed in the restyled body to protect cargo from freezing in the cold season.

Hydraulic control is electro-pneumatic and is carried out from the driver’s cabin. The hydraulic cylinder is telescopic, 3-stage.

Wheel formula - 6x4.

Overview of modifications

Any specialized equipment weighing up to 24 tons can be installed on the KamAZ chassis. The timber carrier for transporting logs and fallen trees to the storage site has superstructures and additional mechanisms with removable sides and steel rods.

Grain carrier Mammoth model 6520 with a capacity of 400 hp. With. used for transporting grain. The KamAZ body is a container in the form of a tank or bunker.

The multilift transports scrap metal and construction waste.

A concrete mixer is a chassis with a rotating container for transporting concrete. It is also called a concrete mixer or mixer.

Price of new and used KamAZ-6520

The cost of KamAZ-6520 varies significantly depending on the technical characteristics. Thus, a 320-horsepower modification without a berth with a load capacity of 20,000 kg, supplemented with inter-axle and inter-wheel locking and platform heating, will cost 2.5 million rubles.

Dump truck with a foreign CumminsISLe unit of 400 hp. in the database it will cost 2.6 million rubles.

Additional equipment can increase the cost of the machine to almost 3 million rubles. However, with rational use of the KamAZ-6520 it pays for itself quite quickly.

The cost of a shift (rent) on a KamAZ-6520 will cost 7,000-9,000 rubles.

Specifications

The main tactical and technical parameters (TTX) of vehicles depend on the modification, purpose and configuration, and the load capacity depends on the installation of additional equipment. Thus, the maximum weight of cargo transported by a log carrier is influenced by the presence of a hydraulic manipulator.

For the basic model KamAZ-6520, technical specifications are presented as follows.

Power unit

The first 6520 vehicles were equipped with a turbocharged diesel engine produced by KamAZ 740.51-320. The power was 320 hp. With. and complied with Euro-2 environmental standards.

Since 2009, new 740.63-400 Euro-3 engines with turbocharging and liquid cooling have been installed on trucks. They are more powerful and environmentally friendly, do not harm the environment and require minimal fuel consumption for the KamAZ-6520.

Characteristics of diesel engine 740.63-400:

• working capacity - 11.76 l;
• rated power - 400l. With.;
• maximum torque - 1766 N*m.

Some models are available with a Cummins Euro-3 engine with a capacity of 8.9 liters and a power of 334 hp. With. and Cummins ISLe Euro-4.

At 100 km, the fuel consumption rate is 45.5 liters; in cold weather, the figure increases to 53 liters. When equipped with a 320 liter diesel engine. With. and a ZF type gearbox consumes 39 liters of fuel.

Transmission

Trucks with engines 740.51-320 and 740.50-360 are equipped with a mechanical 8-speed gearbox (gearbox) type 161 or German-made ZF-16S151.

Cars with the 740.14-300 engine are equipped with a ZF-9S109 9-speed manual transmission with low gear.

The ZF-16S151 gearbox on the new tonneaus is a mechanical, 16-speed gearbox, consisting of a main 4-speed gearbox with a built-in 2-speed divider located at the front and a 2-speed planetary gearbox, which is located behind the main gearbox.

Gear shifting on KamAZ is carried out according to the scheme using a special lever.

• width - 2500 mm;
• height - 3005 mm;
• body dimensions - 4700x1850x2490 mm;
• body volume - 12 m³;
• axle clearance - 190 mm;
• wheelbase - 3600 mm;
• minimum turning radius - 9300 mm;
• tire sizes - 12.00 R20 (320 R508).

The volume of the body depends on the configuration and can reach 20 m3 (meters in cubes).

• curb weight - 9.2 tons;
• total weight - 33.1 tons;
• front axle load - 4520 kg;
• load on the rear trolley - 4680 kg.

The filling capacity of the fuel tank is 350 l.

Advantages and scope of application

The significant advantages of the Kamaz 6520 dump truck, in addition to the volume of the body, which allows transporting so many different materials, are:

1. Low cost relative to foreign competitors.
2. Confident cross-country ability over our Russian potholes.
3. Operation on low quality fuel.
4. Availability of spare parts makes preventative and repair maintenance easier.
5. Large fuel tank capacity - 350 l.
6. Increased stability during unloading due to the hydraulic cylinder of the façade structure.
7. Body volume increased by 15%.
8. Availability of safety steering wheel, etc.
9. Increased maneuverability.
10. Economical fuel consumption of the KamAZ 6520, namely, under normal conditions the dump truck consumes 45.5 liters per 100 km, at sub-zero temperatures - up to 53 l/100 km, when driving around the city - up to 50.6 l/100 km. In areas where there are no roads, the car spends exactly fifty liters per 100 km. Thanks to such indicators, the car is in demand abroad.

All these advantages have made and continue to make this dump truck one of the most popular heavy trucks, which is in demand in mining areas, for agricultural harvesting work, in the municipal sector for waste removal, at large-scale construction sites for the delivery of building materials and removal of construction waste, as well as in other areas where machines that can withstand heavy loads are needed.

Disadvantages and advantages

Cars produced before 2009 have the following disadvantages:

• poor functioning of ABS;
• low generator power;
• the air system is not improved, malfunctions occur in the hydraulic mechanism;
• frequent malfunctions of the brake system and fuel supply mechanism;
• difficult access to spare parts and components;
• low acceleration speed when loaded;
• poor quality of bearings in the gearbox of the middle and rear axle.

Among the advantages are the following:

• high load capacity;
• good maneuverability;
• high engine power and reliability;
• low maintenance costs;
• efficiency;
• availability of high-speed engine start.

Operation and Maintenance

Operation of KamAZ trucks must be carried out in accordance with the operating manual. The service life of the vehicle before major repairs is 500 thousand km. TO-1 is carried out with a mileage of 5.5 thousand km, TO-2 - at least 16.5 thousand km. An oil change is performed every 10-15 thousand km.

Ignoring the instructions leads to failure of the lubrication system and engine.

Restyled models also undergo maintenance according to approved regulations. All records are kept in a special journal.

Electrical diagram

Using a color electrical diagram indicating all electrical equipment, sensors and mechanisms connected to the truck’s on-board network, you can repair the wiring. The color of the lines corresponds to the color of the cables of the standard electrical wiring.

Modifications

The KamAZ-6520 dump truck became the basis for a whole family of trucks belonging to the heavy class. The new design ensured compliance with all current requirements of domestic and foreign legislation. The vehicle's service life before major repairs is 500 thousand kilometers. The first maintenance should be performed after 5500 km, the second after 16500 km. Over the years of production, about a dozen modifications of the KamAZ-6520 were produced, the differences between which consist in minor design features and configuration options. Currently, the KamAZ-6520-73 modification remains in mass production, in nine configuration options, each of which has its own factory index. But they all have the same engine brand - KamAZ-740.73-400 (Euro-4), with Common Rail; and the manual transmission is also similar - “ZF-16S1820”. In addition to the rectangular and enlarged “grain” body, U-shaped (or, in Russian speaking, “trough-shaped”) bodies are also installed on the KamAZ-6520 chassis.

Since the KamAZ-6520 was the first model developed by our vehicle in quite a long time, new specialized trucks were soon created on its basis. So, in addition to the already mentioned “grain” modification “KAMAZ-6520-23072-63” with a 33-cc body, the first domestic four-axle trucks were built on the basis of the KamAZ-6520 chassis. This is a KamAZ-6540 dump truck with an additional steered axle (8x4 drive), capable of transporting up to 18.5 tons of various bulk cargo. This is a four-axle heavyweight (also 8x4) KamAZ-65201, which is capable of carrying up to 25 tons of cargo. Such specialized machines are in demand wherever there are axle load restrictions. And for operation in the most difficult road conditions - in quarries, off-road, an all-wheel drive three-axle (“6x6”) modification of the dump truck was developed - “KAMAZ-6522”, with a maximum load capacity of 19 tons.

Owner reviews and cost

A new KamAZ-6520 with standard options is bought for 3-3.5 million rubles.

For a dump truck produced in 2022, 6520-73, the price is 4 million rubles.

On the secondary market, the purchase and rental prices are much lower.

The cost of model 36520 produced in 2012 with a mileage of 50 thousand km is 2.25 million rubles, and model 6520-73 produced in 2014 is 1.75 million rubles.

Heavy trucks are often rented. The estimated cost is 10-15 thousand rubles per shift.

Nikolay, 45 years old, Rostov-on-Don: “I bought a KamAZ not new, but on the move. Replaced the piston group and cylinder block. I started working better. At the 100,000th mileage the liner burst and the pads riveted. The fuel consumption was 48 liters, now it barely reaches 37 liters. The car is not bad, but requires constant minor repairs.”

Evgeniy, 53 years old, Ufa: “Model 6520-73 is an excellent option for work. Soft seats, all with buttons. When loaded, the car picks up speed up to 100 km/h, does not squeak, and the brakes are good. I don’t load more than 20 tons.”

Flaws

Like any other special equipment, this truck has, or rather, had the other side of the coin, that is, disadvantages, namely: the drivers were not happy with the performance of the speedometer, brakes and fuel system. But these dissatisfactions were typical during the operation of the initial modifications, which were eliminated in subsequent models.

We should probably mention one more early drawback - this is an old model of the cabin with numerous imported components. By the way, this trouble was also eliminated in 2003 through restyling.

In general, during the release of the line of this car, the following updated modifications appeared:

• Kamaz 6520-006, 6520-01061, 6520-011-60, 6520-024-61, 6520-120-61 - all these models come with a rear unloading type and cost from 2.5 million rubles.
• Kamaz 6520-029 - basic version with a body volume of 20 m3
• Model 6520-73 - comes with heated body, volume 12 m3.
• Modification 6520-43 is a dump truck that meets Euro-4 requirements and costs from 3.5 million/rub.
• Kamaz 6520-010-60 comes with a three-way unloading type and a pricing policy of 2.52 million rubles.

A used model can be bought from 420,000 rubles to 1.75 million rubles, depending on the year of manufacture and operational condition; renting a KamAZ will cost the company from 6,000 to 10,000 per shift.

Models of trucks Kraz S20.2 and MAZ 5516 can be considered as domestic analogs, and Howo ZZ3257M3647 as foreign ones.

Technical features

The body, taking into account new modifications, can have a volume from 12 to 20 m3.

Overall dimensions of KamAZ 6520

This unit can be unloaded from the rear or from three sides, depending on the modification. The body has the ability to lift large objects due to a strong hydraulic system at an angle of 50 degrees. By the way, the volume of the body can be increased by using extensions or extended sides.

The turbocharged engine is a classic diesel engine that served on these machines until 2008. It had intercooling and complied with Euro 2.

Then the manufacturer, in the face of competition and market demands, decided to improve the motor. The result is a powerful unit that complies with Euro 3 standards, captivating with its environmental friendliness.

Note!

The diesel volume is 11.76 liters and the maximum power is 400 liters per second.

By the way, the fuel consumption rate for the KamAZ 6520 is set out above; let us only recall that the dump truck is economical in this regard, which attracts foreign consumers. In addition, the unit can accelerate to 90 km/h.

Thanks to the constant development of engineers at the Kama Automobile Plant, the distinctive rumble has gone away, which has significantly increased the comfort of its operation and reduced the load on the driver.

The updated modern cabin is equipped with a high ceiling, rear-view mirrors, and also the latest steering with a mechanism that protects the steering rods from failure. In addition, the design features of the new cabin have made it possible to reduce vibration, which helps to increase the driver’s working comfort.

The design contains an anti-lock braking system. Later variants use disc brakes.

The original version had a Zahnrad Fabrik sixteen-speed manual gearbox, ready to cover up to 1,000,000 km. This variation was used in quarries and in difficult places. There were also models with nine stages YaMZ-239, intended for use in urban environments.

The gearbox with a divider from foreign manufacturers was distinguished by easy and convenient control of the lever, which was located horizontally forward.

Kamaz dump truck model 6520

KamAZ-6520

• Car make: KamAZ
• Country of origin: Russia

• Year of manufacture: 2002
• Body type: Dump truck

The KamAZ-6520 truck is the leading truck among heavy-duty trucks. It’s no longer a secret that KamAZ vehicles serve as reliable assistants and are efficient, regardless of any conditions and situations. Dump trucks of this company are the most durable in the whole world, which is confirmed by 10-time first places in the transcontinental rally.

• City cycle: 49.3 l
• Extra-urban cycle: 41.1 l
• Combined cycle: 45.2 l

KamAZ 6520 is a reliable dump truck of its kind that can overcome any difficulties on the road in any weather conditions. These cars are the most durable and therefore they have repeatedly won transcontinental rallies. An amazing experiment showed that even an explosion of eight kilograms of TNT is not a hindrance for a truck.

Over the entire history of production, the Kamaz company has produced over 2 million vehicles of various types, and in the near future the plant plans to produce 100 thousand trucks every year. This model is one of the most basic in the range of dump trucks with its main feature - the possibility of rear unloading. Kamaz is designed to transport large quantities of cargo, as well as sand, and its carrying capacity reaches two tons.

All criteria are met, namely: safety, comfort, handling and noise insulation. In total, the volume of the rear part intended for transportation is 12 cubic meters. Also, if you need to transport fairly large materials, it is possible to expand the body with special sides. But there are also some disadvantages - for example, low speed when the dump truck is fully loaded, difficulties arise when finding spare parts for this model, and the braking system is poorly developed.

But in general, the truck is in great demand on the market due to its large load capacity, which allows it to transport heavy loads over fairly long distances and its relatively low cost. The dump truck also excels in efficiency. In the city its consumption is approximately 50 liters, and on the highway 47 - and this is quite low, considering its dimensions.

Car history

For some time now, the line of the Kama Automobile Enterprise has not had a heavy-duty car that could meet the latest standards that the market demands today.

Therefore, we decided to release the efficient KamAZ 6520 model, which, in addition, made it possible to increase its carrying capacity. This car remained among the leaders of the car market for more than 10 years and, at the same time, remained popular and in demand.

Of course, KamAZ vehicles have always been produced with high quality, and could work where other vehicles were unable to do so, but until the 2000s, dump truck versions began to lose out to competition in the global vehicle market, lagging significantly behind in technical terms.

The car began its design history back in the 1990s. It was at that time that the domestic car market experienced a shortage of special vehicles that would be ready to function in difficult Russian conditions and transport massive loads.

Although in those years the plant produced quite a few cars, however, their technical component was much inferior to foreign versions. They used KamAZ 65115 quite actively, its carrying capacity was 15,000 kg, but even that was no longer enough.

As a result, the Kama Automobile Plant managed to develop a car marked 6520, the wheel formula of which is 6x4. He could be called an excellent worker who could cope with almost any task. It had design features such as ABS, an all-metal welded platform and control of operation from the cab.

History of creation

KamAZ-6520 dump trucks are one of those main families of the Kama Automobile Plant, which allow the company to confidently maintain a leading position in the truck market in the CIS. Being designed for the transportation of bulk construction, agricultural and industrial cargo on roads with an axle load limit of 10-13 tons, this particular vehicle more than ten years ago became the very first heavy-duty dump truck in the KamAZ plant product line.

Until the beginning of the 2000s, the most powerful dump trucks produced at the Kama Automobile Plant were the KamAZ-55111 with a carrying capacity of 13 tons, as well as the heavier KamAZ-65115, with a carrying capacity of 15 tons. But at the beginning of the new century, a real grandiose “construction boom” unfolded in the country, and the capabilities of these machines were not always sufficient for the growing needs of the booming construction industry.

Important! The vehicle is not a modification of previously produced trucks or a copy of vehicles from other automakers.

Therefore, in just a few years, a new model of a dump truck with a 20-ton payload was quickly developed. This vehicle, designed for large-scale construction, quarrying and agricultural work (grain trucks), having a load capacity of up to 20 tons, has become the most powerful dump truck in the vehicle line. Its serial production started in 2003. An important point: KamAZ-6520 was not a modernization of dump trucks previously produced by the company, or a copy of any of the trucks from other manufacturers. This is a completely new model, developed from scratch.

Important! KamAZ 6520 is the basis for a family of heavy-duty vehicles. About a dozen of its modifications have already been released. The design meets all the requirements of Russian and foreign standards.

By 2003, many KamAZ models had already undergone restyling and acquired a more comfortable new-style cabin: with more comfortable seats, new-style instrument panels, climate and acoustic systems. However, the new KamAZ-6520 dump truck received an outdated cabin, developed “under Tsar Gorokh,” and was equipped with it until 2007. Then it was finally replaced with a restyled one. However, not only KamAZ, but also many other automakers have traditionally not considered it necessary to take care of the comfortable work of dump truck drivers. But now the KamAZ-6520 cab is in no way inferior to other company vehicles in terms of comfort.

Appearance

The operating systems and components of the truck were designed to withstand difficult operating conditions. Our review guest cannot be called an improved working version - this is a completely new model that was developed from scratch. From the very beginning, the car was equipped with a previous model cabin, which is already outdated.

They decided not to touch it for now because the main efforts were directed towards researching the innovative chassis. A little later, the cabin was replaced with a more improved one. This made it possible to abandon the literally obsolete and morally old cabin. The new one began to look more beautiful, received new headlights (lens optics) and a visor. The car had a high roof, which had a lower belt and a unique buffer.

The fact that this element was introduced into the design made it possible to ensure the most convenient boarding and disembarking of people. The windshield was not divided, but was solid. As many as 3 wipers will be able to clear it from rain or snow, which will allow you to get better visibility. There are also additional mirrors that will help you be more mobile without fear of catching the car and damaging it.

The cabin is raised using a standard hydraulic booster. The section for the mechanical method of lifting the cabin was placed on the traditional right side, but under the passenger door between the lower and upper legs.

If there is a special need for transporting large cargo, it is possible to increase the body volume with special sides. They can be installed by the factory itself.

The body itself is also presented with an oval section of 16 cubes. The shape of such a body makes it possible to reduce the sticking of cargo by changing the center of gravity of the load closer to the middle of the body.

Cabin interior

Getting into the KamAZ-6520 cab, you immediately notice the presence of a safety steering wheel, which has received a new look. The steering wheel control device already had a hydraulic rotation limiter, which was intended to prevent the steering rods from coming out of position.

The steering column itself is adjustable in angle, which will allow it to be adjusted to any driver. The dashboard is quite informative, all the required controls are at hand, the buttons are all convenient and pleasant to the touch.

The instrument panel received two large dials, where the left one shows the speed mode, and the right one shows the speed of the power unit (up to 3,000 rpm). There is a monochrome small rectangular display showing other relevant information (mileage, etc.).

They didn’t forget to install cup holders, and on the front panel there is a small island table that can be used for your needs. The cabin is much more comfortable than previous models; the glass is panoramic, which increases visibility. The company's design staff decided not to install a sleeping place.

Moreover, the KamAZ 6520 can even have an air conditioner for an additional fee, which allows you to close the windows in hot weather in the summer and work in a cool environment, getting less tired. There is convenient access to fuses.

The upper part received a pair of speakers located on the sides, glove compartments and a recess located in the middle for various things. The doors still don't have power windows, which is a bit disappointing.

We made thermal and noise insulation of the engine and gearbox, which made the driver and passenger feel more comfortable. The cabin received air suspension, which increases the level of comfort for the driver and passenger.

In addition, the KamAZ-6520 has pneumatic seats, which are independently adjustable (can be raised, lowered, moved forward and backward). The new domestic dump truck is quite easy to drive, not much heavier than a passenger car.

Features of the cabin design

The design of the KamAZ 6520 cab remained without significant changes until 2007, when it was supplemented with a berth and an updated U-shaped radiator grille. The headlights were also modified and the size of the bumper was increased.

The body part of this model had one serious drawback, namely the lack of a heating system, which created a number of difficulties when transporting certain building and consumable materials. Subsequently, this defect was corrected, and in the modern modification of KamAZ 6520 there is a special visor that covers the space between the cab and the body.

Other design features include an ABS braking system, an all-metal welded platform and the ability to control key elements directly from the cab.

KAMAZ 6520 dump truck platform

Among other innovations that affected the KamAZ 6520 cab, it is worth noting the safety steering wheel and the presence of a hydraulic turn limiter. The steering column can be adjusted in angle. Thus, each driver is able to customize the control of the dump truck based on their own considerations of convenience. In models released after 2009, the cabin is equipped with air suspension and has an improved exterior. A sufficient number of dump trucks were equipped with drive axles from the famous Hungarian manufacturer Madara.

Specifications

Power unit

If we take the time until 2008, the Russian company equipped the 6520 dump truck with a standard engine operating on diesel fuel, which meets all Euro-2 standards. A similar power unit received intercooling and a turbocharging system. But later the automobile plant decided to make amendments to the engine.

As a result, this made it possible to equip the advanced diesel power unit so that it meets Euro-3 environmental standards. The KAMAZ 740.63-400 V-shaped 8-cylinder engine has a displacement of 11.76 liters and produces up to 400 horsepower with a maximum torque of 1,225 Nm.

This installation allows the dump truck to reach a maximum speed of 90 km/h, which is quite a lot for a truck. It is also possible to install an American Cummins engine with similar power. In summer, the KamAZ 6520 power unit consumes about 46 liters per 100 kilometers, but in winter it is already 53 liters. The fuel tank is designed for 350 liters.

Transmission

A new sixteen-speed manual gearbox ZF Ecosplit 16S 1820 TO was introduced for the Russian dump truck. Interestingly, the box is the company’s own production, and its structural elements allow it to be used for 1,000,000 km. The clutch is a diaphragm single-disc with a hydraulic drive and a pneumatic booster.

Suspension

The suspension is of the spring type. Wheelbase 6x4. Curb weight – 12,950 kg. Loading capacity - 20,000 kg (drivers often transport more, for example, up to 25 tons, but the plant does not recommend overloading the dump truck).

The total weight is 33,100 kg. To increase the stability of the KamAZ 6520, anti-roll bars were installed on the front axle and rear axle. Therefore, a bad road does not frighten a dump truck.

Device and reviews

KamAZ-6520 is equipped with a large dump platform with rear unloading. The body is capable of lifting even large loads thanks to powerful hydraulics. The volume of the body when transporting light loads can be increased by means of extension sides provided by the design. Excellent traction and dynamic characteristics allow the machine to overcome an incline of 25% even when fully loaded.

The traditional “Kamaz” rumble of the vehicle disappeared thanks to a number of measures that made it possible to make the model comply with the requirements of UNECE rules. Reduced noise makes working on KamAZ-6520 more comfortable.

inside the cab of KamAZ-6520

The model is equipped with a modernized cabin with a high roof, which has a lower belt and an original buffer. The introduction of an additional step into the design of this element ensured maximum ease of landing. A set of rear-view mirrors also appeared here, which increased the visibility for the driver driving the dump truck.

A new type of safety steering wheel has appeared in the dump truck cab. A hydraulic turn limiter was added to the steering mechanism, designed to prevent breakage of the steering rods. The car was also equipped with an anti-lock brake system.

The drive axles of KamAZ-6520 have planetary wheel reduction gears and a 1-speed main gear. This design, in addition to increasing ground clearance, ensures greater reliability and durability of bridges even under constant overloads. The frame spars have the same cross-section along the entire length; solid reinforcements of the side members make the load-bearing elements of the truck more durable.

Vehicle stability is achieved by installing anti-roll bars on the front axle and rear axle. Difficult road conditions will not be a problem for KamAZ-6520. Locking cross-axle differentials can significantly increase its cross-country ability.

The car also had its downsides. Owners complained about the fuel and brake systems, speedometer and generator. However, problems appeared only in the first modifications; later the manufacturer eliminated them.

In 2010, the Kama Automobile Plant presented a restyled version of the dump truck that meets advanced requirements. Now this model is one of the flagships of the brand.
