Dump truck 6520 KamAZ: technical characteristics, load capacity, body volume

The KamAZ dump truck is reliable and efficient under any conditions and in any situation. Heavy trucks of this brand are the most durable vehicles in the world, confirming this with ten-time victories in the transcontinental rally. The main opponents - Czech and Dutch racers are not able to even come close to their result. Read about the popular Kamaz 55111 model.

The car is even capable of withstanding an explosion of eight kilograms of TNT! The armor-piercing vehicle manufactured by KamAZ is capable of accelerating to 80 km/h, weighs 17.5 tons, and can even withstand the loss of a wheel from the wheelbase.

Back in 1993, KamAZ could have disappeared from the market, since absolutely the entire territory of the production area was engulfed in fire; in the 2000s, the company’s debt exceeded the external debt of Monaco, but already in 2011, a record 208 cars rolled off the assembly line per day, against the standard of 204.

Over the history of the brand, KamAZ has produced 2 million vehicles for various purposes, and by 2022 it is planned to produce 100 thousand vehicles annually . In addition, it is worth noting that KamAZ has a little bit of Mercedes, since the German company Daimler acquired a 10th share of the concern’s shares, which made it possible to introduce heavy-duty Mercedes to the domestic and world markets.

The company has also launched the production of not only heavy trucks, but also buses and agricultural equipment designed specifically for our harsh conditions (in particular, combines).

There has been an increase in the sales volume of dump trucks; today it reaches a high level, but the Kamaz dump truck model 55111 quite harmoniously combines the necessary criteria that allow any buyer to decide to purchase the necessary truck with a high level of reliability, and a very reasonable price, excellent performance characteristics and excellent quality.

Visually, such a truck resembles a dump truck, the long-proven 5511, but differs greatly in load capacity. The mass of bulk cargo that such a truck can transport is 20 tons. A dump truck with a body volume of 4 cubic meters cannot cope with such a task. Experienced drivers speak only favorably of KamAZ trucks. The equipment is initially highly rated due to the 6x4 wheel formula, it has two drive axles, powerful wheel gearboxes, a balancing trolley, plus very comfortable disc wheels equipped with tube tires

Dump truck 55111 is an improved modification of the 5511 vehicle, the volume of the KamAZ dump truck body is 6.6 cubic meters. As soon as it appeared in 1988, the car immediately became one of the popular machines for construction work in the country. It is reliable and practical, very easy to maintain and operate - it combines the characteristics necessary for work equipment. The main purpose of KamAZ dump trucks is the transportation of bulk cargo of an industrial or construction nature. Kamaz Mammoth vehicles with a body volume of 20 cubic meters (photo below) are actively used in quarries, in the development and extraction of minerals, smaller models are used in construction work and for agricultural needs.

Mammoths are dump trucks, model 6520. They have a large Kamaz 6520 body volume, have a high load capacity of 20 tons, and a 6x4 wheel arrangement. Their total weight reaches 33 tons. Mamont dump trucks are not updated models of the previous generation (such as KamAZ-65115 or KamAZ-55111), they are a completely new unique development. The KAMAZ 6520 car has a body volume of 20 cubic meters and is designed to transport a variety of construction or industrial materials on roads that allow vehicles with a maximum permitted axle load of 10-13 tons.

Articulated dump trucks are used when increased cross-country ability and good maneuverability are required. The main design feature of this type of truck is that it is equipped with an articulated frame. There are models that have three axles (six driven wheels). An example would be the body volume of a Scania dump truck of 22 cubic meters.

In addition, modern models have the ability to turn off the cross-axle differential.

Quarry dump trucks (off-road dump trucks) are used where open-pit mining of any mineral resources is available. Today, the most common is a two-axle rear-wheel drive design, equipped with a rear body unloading system. The MAZ dump truck with a body volume of 21 cubic meters and a load capacity of 30 tons has also proven itself well in quarry work. In the course of experiments carried out in quarries using three-axle dump trucks, such a system was found to be extremely inconvenient. For large volumes, Belaz vehicles can be used, but such heavy vehicles are completely unsuitable in urban conditions and especially in rural areas, but the volume of the MAZ dump truck body allows its use in the city, as a light and medium-duty truck.

The use of dump trucks helps increase the productivity (volume) of transportation in all industrial sectors, and mining is no exception, as well as in agriculture. If you replace a single dump truck, the volume of the body of which does not allow you to transport the entire load in one trip, then the road train will have a great advantage:

Firstly, excess load (overload) on equipment is eliminated, which reduces the risk of increased wear and premature breakdowns

Secondly, the transported volume (and weight) of cargo per trip increases, which the operating instructions and body volume of a single MAZ dump truck will not allow.

The main advantage of small-tonnage KamAZ trucks, for example, Kamaz M3 body volume, is its relatively small dimensions, which allow movement in narrow city streets and narrow roads of gardening associations. The advantages of such special equipment of all models include the simplicity and reliability of the body structure, a good tilt angle of the platform (up to 60°), excellent visibility from the cab, in addition, road stability, good handling, and an economical fuel system.

Parameters of Kamaz-5320

KAMAZ 5320 onboard tractors with a body volume of 9.8 cubic meters were produced at the Kama Automobile Plant and were intended to work with trailers. The body of model 5320 is a metal platform with opening side and rear sides. The flooring is wooden; it is possible to install the awning yourself. The volume of the KAMAZ 5320 body allows you to transport containers and loads that exceed the dimensions of the vehicle in height or length (for example pipes) in compliance with traffic safety rules (traffic rules)

ABOUT

was formed back in 1969. In 1976, the first car rolled off the assembly line. Officially, 1969 can be considered the starting point for the KamAZ enterprise. The small town on the Kama River Naberezhnye Chelny became known as a city of heavy trucks. The advantages are irrefutable: the ideal geographical location (at that time the center of the Union) affected the transportation of parts and spare parts.

In addition, the region had a powerful construction organization, KamGESenergostroy , which made it possible to cope with the construction of an industrial complex and infrastructure in a short time.

In 1969, the first bucket was pulled out of the ground, which marked the start of the creation of the Kama Automobile Plant. The complex turned out to be large-scale, spread over an area of ​​57 km2.

Products from the manufacturer

At the moment, literally, the second heavy-duty truck traveling around the CIS is produced by KamAZ. The corporation has more than 150 organizations and 12 large factories. This allows the company to be in 16th position among the world's top heavy-duty truck manufacturers. The top 5 largest dump trucks in the world are in our ranking.

The enterprises are represented in Iran, India, Pakistan and Vietnam. In the long term, by the end of the decade, KamAZ may become a leader , capturing half of the world production in this area.

Device Features

Having a platform volume of 6.6 cubic meters, the load capacity of the dump truck is 13 tons. The body has a bucket type, it is made in the form of an all-metal welded structure. The platform is heated by exhaust gases, which allows cargo to be transported even in cold conditions, without the cargo freezing to the body. The dump truck is unloaded through the tailgate. To protect the space between the cab and the body there is a special visor. Using remote electro-pneumatic control from the cab, the driver can easily control the tilting of the loading platform.

Specifications

The model 55111 dump truck is equipped with a turbocharged diesel engine and has an intercooling system. The power unit has a power of 240 hp and meets high Euro-2 standards. Its fuel tank capacity is 350 liters, diesel fuel consumption is 30 liters per 100 kilometers. The transmission is a ten-speed manual transmission with remote control.

Appearance

The exterior of the 6520 dump truck has been modernized, and it looks especially impressive with the new cab

New headlights attract attention; a visor has appeared. It has a high roof, which improves visibility, especially with a one-piece windshield that is effectively cleaned by three wipers

The presence of a buffer and a lower belt ensures quick boarding and disembarkation. Large mirrors improve visibility when reversing in tight spaces. A standard hydraulic booster is used to raise the cab. A mechanical cabin lift system is located under the right passenger door. It was decided to install a 16 cc all-metal body with high sides on this KAMAZ model. Its peculiarity is its oval cross-section. This shape helps reduce the sticking of bulk materials by changing the center of gravity during unloading. An important point is that for this dump truck it is possible to increase the volume of the body using special sides. They can be ordered and installed directly from the manufacturer. This significantly expands the functionality of the car.

Modifications

The GAZ-53 car was a mass-produced car of the Union republics. There were 4 million machines in operation throughout the country in their usual, as well as dump and specialized versions.

In the period 1961-1967, the GAZ-53F car was produced. It was equipped with a six-cylinder engine with a power of 82 hp. from the GAZ-11, with a four-speed gearbox, it ensured the transportation of 3500 kilograms of cargo, fuel consumption of 24 liters per 100 kilometers of low-octane gasoline. At the time of the model's production, there was no V-twin power unit in production.

For the 53F model, the six-cylinder GAZ-11 engine was boosted, and the compression of the mixture increased. A hypoid rear axle was also not invented, so a mechanism from the 51A model with bevel gears was installed.

In fact, the gas 53 dump truck with a body volume of 4.8 cubic meters of the F model, according to its technical characteristics, was a transitional (intermediate) model between such series as 51A (with a load capacity of 2500 kilograms) and SAZ-53B (the load capacity was increased by a ton), this was achieved by increasing to 3 .7 meters of base and installation of new tires 8.25-20, which are mounted on steel wheels.

The car was used not only as a dump truck; sewage disposal trucks, milk tankers and fuel tankers were also common.

The GAZ-53 car was not a complete design; due to constant breakdowns of mechanical parts, it did not become popular either among drivers or among workers of various repair services and motor transport enterprises. This truck was equipped with a noticeably weak engine, had an unreliable axle, and was produced until 1967.

In the period 1964 -1983, models from the 53 and even 53A series appeared on the roads, with a load load of 3500 and even 4000 kilograms. They were equipped with a more powerful ZMZ-53 engine with a power of 115 hp, which ensured an increase in speed to 85 km/h with a fuel consumption of 25 liters for every 100 kilometers. The body volume of the gas 53 dump truck has not changed.

Popular representatives in their repertoire

Currently, KAMAZ grain trucks are divided into two main types:

• Side structures;
• Tipper options with an automatic platform (there is an option - self-unloading).

Important All-wheel drive two-axle truck KamAZ-4326
To ensure that cargo transportation does not turn out to be expensive in terms of fuel consumption, or frequent in the number of trips, you need to focus on the technical characteristics of the truck.

For example, a KAMAZ marked grain carrier 45143 can accommodate only 11.5 tons of cargo. The engine power is 300 horsepower, and the tank capacity is decent - 500 liters.

The model with index 776012 can withstand up to 14.5 tons. Here, just like in the previous version, a Euro 4 environmental class motor is built in.

The onboard modification with number 6520 can withstand up to 20 tons of transported cargo, and this is even more.

Model number 552900, which is popularly called KAMAZ grain dump truck, is attractive for the following features:

• three-way unloading;
• nominal lifting capacity 15 tons;
• large cabin with a decorated berth;
• the presence of a towing device;
• the presence of all necessary devices on the road.

The toxicity standard is the same - Euro 4. Among all the features, it should be noted that the built-in hydraulic drive is equipped with a pneumatic booster.

Calculation of body volume for transportation of building materials

The calculation of crushed stone is carried out similarly to the previous one using the density indicator:

Actual load capacity

• when transporting 6.5 tons of crushed stone (1300 kg/m³), the number of its cubes in ZIL will be: 6500 kg: 1300 kg/m³ = 0 m³;
• when transporting crushed stone (1500 kg/m³) cubes in ZIL there will be:

6500 kg: 1500 kg/m³ = 4.33 m³.

Both cases do not require a volume of more than 5 m³.

For each type of bulk materials, it is possible to calculate the capacity for loading into a certain type of transport, using data on their density.

Table of density values ​​for some types of crushed stone:

Tuff crushed stone with a body of 5 cubic meters can be transported accordingly:

5 x 800 = 4000 kg (4 tons).

When making calculations, it must be taken into account that the density of building materials also depends on some parameters:

• high humidity - it increases the weight of the same amount of material;
• the presence of various impurities that can make the material heavier or lighter;
• fraction sizes. There is a single scale for determining standard parameters in each individual case.

Determination of volume

Sometimes we don’t even think about how much a cube of this or that material weighs, for example, crushed stone or sand. However, to calculate the cost of transportation services, road carriers use an indicator that characterizes the weight of the cargo.

How many cubes of a particular material will fit in a KAMAZ truck depends on various factors. Among them the most important can be identified:

• Vehicle modification. For each model, the maximum load capacity values ​​are determined in cubic meters or tons;
• Type of material transported. Each of them has certain characteristics: density, humidity, fraction, etc. As a result, different materials will require different volumes for the same weight.

Knowing all the necessary data, you can make the calculations yourself. The table calculates the mass density of some materials that are most often transported on KAMAZ vehicles.

Sand

When transporting sand, its type is of particular importance. Most often the following are transported in the back of a KAMAZ:

• Dry sand;
• Building;
• Construction dry friable;
• Construction dry compacted;
• Career.

The bulk density of each of them varies from 1200 to 1700 kg/cubic meter. Thus, to transport 10 tons of sand, a platform with a volume of 12 to 17 cubic meters will be required.

Crushed stone

Transporting crushed stone also requires careful calculation to select the optimal truck. To do this, it is necessary to take into account the fraction of the building material. The bulk density indicator depends on it.

The following types of crushed stone are used on construction sites:

• Granite fraction from 20 to 250 mm. Its density will vary from 1370 to 1400 kg per cubic meter;
• Limestone fraction from 10 to 70 mm. The bulk density of such building materials varies from 1250 to 1330 kg/cubic meter;
• Crushed gravel offers a wide range of fractions. Its bulk density will be from 1600 to 1730 kilograms per cubic meter;
• Slag with a density of 800 kg/m3;
• Expanded clay fraction from 5 to 40 mm. For it, it is necessary to select a dump truck based on a density from 210 kg per cubic meter to 450;
• Secondary, which is characterized by a density in the range of 1200 - 3000 kg/cubic meter.

Land for the plot

In addition to building materials, KAMAZ trucks are used to transport land for summer cottages. This need arises when carrying out work on landscaping a personal or local area or registering a land plot. As with other materials, in this case the maximum volume of transported cargo depends on its density. On average, one KAMAZ can deliver from 5 to 7 tons of earth to your site.

Firewood

Thanks to the design features of the platform, KAMAZ is perfectly suited for transporting timber. Depending on the modification of the KAMAZ dump truck, one vehicle can load from 25 to 45 cubic meters of logs.

If you use KAMAZ to transport sawn firewood, then one vehicle will be able to transport from 5 to 7 cubic meters of logs. This indicator is influenced by the shape of the cut and the option of laying firewood in the car body.

Advantages and disadvantages

Pros of the car

• High load capacity KAMAZ-6520.
• Passability even on bad roads.
• Ease of operation and repair.
• Good visibility for the driver.
• A line of powerful, reliable and economical engines.
• Comfortable cabin with a well-thought-out interior, adjustable steering wheel and pneumatic shock absorption.
• High-quality lensed optics.
• Good noise and heat insulation.
• The preheater makes starting easy in any weather.
• Anti-lock braking system.
• Wide selection of different modifications.
• Availability of additional options, such as installation of air conditioning.

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.
