KamAZ products have proven to be reliable and powerful vehicles that are perfect for use in any region of Russia. They are distinguished by high engine performance: high fuel efficiency, maximum power density and high torque.
The production of the KamAZ 6522 tractor began at the Kama Automobile Plant relatively recently. The prototypes of the model were made on the basis of the KamAZ 65224 chassis with single tires. The car was intended for the transportation of various industrial goods and the transportation of bulk materials with a mass of not more than 19 tons. A nice addition was the protective visor that appeared between the cab and the truck platform. The platform itself has exhaust gas heating and a remote lowering mechanism.
Modifications
In addition to the basic variation, the Kama Automobile Plant offers several modifications of the KamAZ 6522 car. Among them are the versions:
- KAMAZ 6522-63, which has a more modern design. This change in appearance is due to a restyled cabin that combines comfort and reliability. The total weight and wheel formula of this model and the basic version are similar. Their technical characteristics do not differ either. However, the KamAZ 6522-63 model is equipped with a foreign ZF mechanical transmission, which makes it possible to significantly increase the vehicle's handling;
- KAMAZ 6522-027. It is the latest modification of the truck. The model is also equipped with a ZF manual gearbox. However, she does not have a restyled cabin. The technical parameters and carrying capacity of this variation have been preserved. The main changes are in the design features. The model was developed to work in off-road conditions. High cross-country performance was achieved due to the installation of a dual busbar.
It should be noted that KamAZ 6522 is a recognized leader in its segment. Bulk cargo transportation in Russia is in great demand, because the model is actively used by industrial, construction, mining and transport enterprises.
Specifications
The model has a six-by-six wheel formula. The technical characteristics of the KamAZ 6522 are impressive. For machines of its class, the dump truck has excellent maneuverability.
Overall dimensions of equipment:
- length - 7880 mm;
- width - 2500 mm;
- height - 3280 mm;
- outer overall radius - 11500 mm;
- wheelbase - 4080 mm.
The curb weight of the car is 13950 kg. At the same time, 5950 kg fall on the front axle, 8000 kg on the rear bogie. The total weight of the model is 33100 kg (load on the front axle - 7500 kg, load on the rear bogie - 25600 kg). KamAZ 6522 has a load capacity of 19,000 kg. The cargo platform of the equipment can hold 12 cubic meters of cargo, allowing you to place large volumes of industrial and building materials. The body of the car rises back at an angle of up to 50 degrees.
Often this car is used as part of a road train. At the same time, its total mass increases to 47,500 kg. The maximum speed developed by the car is 65 km / h. The maximum climbing angle is 25%.
Fuel consumption
The fuel tank of the KAMAZ 6522 model holds up to 350 liters of fuel. In summer, the fuel consumption rate is 35-35.6 liters per 100 km. In winter, fuel consumption increases to 40 liters per 100 km due to the need for heating. Due to the installation of a special Common Rail system, fuel consumption has been significantly reduced.
Specifications KAMAZ-65222
In 2010, a restyled version of the 6522 model with the index 65222 was released. This is a modern, well-equipped all-wheel drive three-axle dump truck with increased cross-country ability and load capacity. One of the interesting innovations used in this version was the single-wheel arrangement of wheels and tires with powerful lugs. A single-sided tire differs from a double-sided tire in that not two wheels (inner and outer) are installed on the rear axle, but one at a time.
This configuration helped to solve three important problems at once:
- reduce fuel consumption;
- increase the angle of arrival and departure, therefore, the car can overcome more serious obstacles;
- reduce the specific pressure of the wheels on the soil, so that a loaded dump truck can confidently move on viscous soils, snow and sand.
With single tires, there is no problem of dirt filling between the inner and outer slopes. Plus, the movement along the tramline is greatly facilitated, because. there is no weighting effect on the rear outer wheels because the track width between the front and rear wheels is the same.
Of course, the single-sided busbar was far from the only difference between the KamAZ-65222 model and the previous versions. A lot has changed here, starting with the size, exterior and interior of the car and ending with the technical and operational characteristics. So, for example, the resource of his work increased by 15%, and productivity - by 8%. In terms of fuel consumption, the car has become more economical by 10%, and the frequency of recommended service has been almost halved.
Dimensions and mass parameters of KAMAZ-65222
Compared to the base model, the KamAZ-65222 frame has become even longer, due to which the overall length of the vehicle has increased to 8,480 mm (this includes a rear bogie with a center distance of 1,440 mm and a front overhang of 1,420 mm). The dump truck has an overall width of 2,540 mm and a height of 3,290 mm.
The car is equipped with an all-metal 12- or 16-cube dump truck with a rear side for unloading and a front protective canopy. It is equipped with a hydraulic lifting mechanism.
To prevent the cargo from freezing to the bottom of the platform, a system for heating it with exhaust gases is provided. The maximum platform elevation angle is 52˚.
The curb weight of the KamAZ-65222 model is 14,350 kg, the gross weight is 34,000 kg, and the payload is 19,500 kg. The maximum allowable load is at the level of 8,000 kg (front axle) and 26,000 kg (rear bogie).
The outer overall turning radius of the dump truck does not exceed 12 m, and the slope angle that it is able to overcome is at least 14˚ (25%).

Additionally, it includes gaskets, bushings, washers and other elements. In the KamAZ 6522 model, it is the front axle that acts as the leading one.
With a significant mileage, individual working mechanisms and components of the car are subject to significant wear. In the domestic market, spare parts for this model are offered in a wide range. Dealers offer various options for individual elements for cars at affordable prices. At the same time, KamAZ 6522 is highly reliable. The model is perfectly prepared for harsh operating conditions, off-road and large temperature and humidity changes. Fuel is supplied to the engine of the machine mechanically, which greatly facilitates starting the engine in cold weather. It is possible to use different types of tires and wheels of different diameters.
The well-thought-out design of the truck allows it to be used in the conditions of the Far North and Siberia. A reliable imported 16-speed manual transmission ZF16S also helps in this.
The improved cabin installed in the KamAZ 6522 vehicle provides maximum driving comfort. The air suspension also contributes to this. The cabin itself is located above the power plant and has a high roof.
tractor version
Due to the unique features of the body (low center of gravity), the machine has increased stability. The platform of the truck is welded, all-metal with heating and a tailgate. A similar body is completed with KamAZ 6520-73. The model is equipped with a hydraulic mechanism for raising/lowering the platform, which is controlled from the cab.
Due to its high cross-country ability, reliability and ease of operation, KamAZ 6522 is in great demand among Russian consumers and neighboring countries. This model is willingly entrusted with the most difficult work, and it does not fail.
The history of the creation of the KamAZ-65222 model
The production of high-capacity dump trucks began at KamAZ in 1996. At that time, the company produced a 13-ton KamAZ-55111 and a 15-ton KamAZ-65115. However, in the domestic automotive market, the demand for reliable and unpretentious cars with a much larger carrying capacity than the models that existed at that time was constantly increasing.
The problem of a shortage of truly heavy dump trucks could not be solved by modernizing existing trucks, so KamAZ began work on creating a fundamentally new line of vehicles.
The first-born in this family was KamAZ-6520 with a carrying capacity of 20 tons with a 6x4 wheel arrangement, intended for quarry, agricultural and construction work. He came out in 2003.
From old models, this dump truck received only a standard cab, and all components and assemblies that provide load capacity, power and efficiency were new, for example, a reinforced frame, a hydraulic system, a 320-horsepower engine that meets the Euro-2 environmental standard, etc.
The firstborn in the line of heavy trucks KAMAZ-6520 with a 6x4 wheel arrangement
On the basis of this model, an all-wheel drive dump truck-19-ton KamAZ-6522 with a body of 12 mᶟ was created. He was able to prove himself well both off-road and in conditions of fairly low temperatures. Due to the presence of a mechanical fuel system control system, its repair and maintenance was simplified, the car became less demanding on the quality of diesel fuel and started up in cold weather without problems.
This model received a body heating system with exhaust gases, a Bulgarian-made front axle with double universal joints, a 16-speed ZF gearbox and a ZF STEYER transfer case, as well as an updated cab with a hydraulic lift and a slightly “grown up” cargo platform in length.
