Determining the amount of firewood neatly stored is quite simple. It is much more difficult to find out how many cubic meters are in the car that you brought. Consider, for example, how many cubes of firewood are in GAZ 53.
To begin with, we need to find out the full volume of the car body. Standard Lawn has a body volume of approximately 4.8 cubic meters. If you see that the firewood is loaded without a slide, then their volume obviously cannot be higher.
There are body modifications with silo (extended) sides, whose volume is increased by 1.5 - 2 times.
In addition to the volume of the body, how many cubes of firewood are in the lawn are affected by the laying method. More precisely, the presence of stacking: if the firewood is neatly laid, then they occupy almost the entire volume of the body, if they are dumped in bulk, then a lot of free space remains between them. There is a special coefficient for converting the bulk volume into the volume of folding cubic meters. The coefficient depends on the length of the log. For example, for logs of a quarter meter, the correction factor is 0.8, and for logs in 3 quarters of a meter - 0.73.
This means that 4 cubic meters of firewood of average length 25 cm, brought in bulk, after laying will turn into 3.2 cubes.
Is it possible to fit in GAZ 53 6 cubic meters of firewood?
As we already said, if the car has extended sides or if you load a body with a hefty slide, then you can. This becomes more likely if the firewood is loaded using a stacking method, rather than in bulk. In the latter case, even in an 8-mikubov body there may be 2-3 cubic meters of firewood.
Consider how many cubes of firewood are in GAZ 66. The body volume of this car can be different depending on the type, but, on average, it is 3-4 cubes, without extended sides. Such is the maximum volume of transported firewood, taking into account the normal laying on the side.
So, to assess the amount of firewood brought in, you need to know the body volume and the method of stacking firewood. The situation is somewhat complicated when loading "with a slide", but its volume can also be calculated by dividing the wood into 2 conditional geometric figures:
- Box parallelepiped on board;
- Separate slide. For ease of counting, you can even level the slide, making it more gentle.
Adding the volume of both figures (obtained by multiplying the length, height and width) - we get the approximate volume of firewood.
Details Created 03/03/2012 00:00Due to the fact that firewood is mainly sold in bulk, it is often difficult to estimate exactly how much firewood was brought to you. But firewood, like any other product, has physical parameters that can be calculated. In this article we will try to tell in an argumented manner how to calculate the volume of warehouse meters in a car body? As an example, take a "real" body with real wood.
For accurate calculation of firewood, the conversion factors of "bulk" cubes into "folding" cubes and vice versa are used. For example, take the GAZ-53 car (Lawn), whose body volume is 4.8 m 3 (length x width x height). If firewood is purchased "Laying", their volume should be equal to the volume of the body. If firewood is purchased "In bulk" without a "slide" , then for the conversion of bulk cubes into folding ones (i.e., a woodpile), coefficients of 0.73 - 0.8 are used depending on the length and thickness of the log. Calculate: 4.8 m 3 * 0.74 \u003d 3,55 - the average number of folding cubic meters of firewood that can be brought in bulk.
Conversion factors for different lengths of firewood are shown in the table below:
Well, now let's try to solve the following problem: you ordered 6 firewood storage meters 0.28-0.33 m long. After some time, according to your order, a car loaded with firewood arrives to you.
Question: How many firewood storage meters in a car body (for example, shown in the photo below)?
To get the answer, turn on the logic and remember the school. While the car was driving along our roads to you, the firewood somewhat settled on potholes and gully. This is good, because as a result of the shaking, a more homogeneous "pile" of firewood was obtained, and the value that will be obtained after the conversion of firewood "in bulk" into warehouse meters will be more accurate.
Mentally divide the body into 2 parts (Figure 1 and 2). One part (1) is presented in the form of a rectangular parallelepiped and the so-called. "roller coaster".
We determine the volume of the parallelepiped (1) by multiplying the lengths. As a result, we get the volume of firewood in the box in bulk:
V (1) \u003d 3.6m * 2.2m * 0.6m \u003d 4.752m3
Multiplying the obtained value by the conversion factor (for firewood with a length of 0.33 m it is equal to 0.78) we get the number of firewood storage meters in the specified box, namely:
Vcl (1) \u003d 4.752m3 * 0.78 \u003d 3.0707cl.m
Determining the volume of firewood in the "hill" (2) is somewhat more difficult. To do this, it is necessary to simulate the formulas of the curves shown in the photograph, and then, using mathematical methods of integral calculus and transformations, derive the volume occupied by the slide (2) in the body. :)
However, we will not do this, since there is no time, and we don’t want to delay the car (do we need to quickly and approximately?), But we will proceed as follows:
Instead of a “slide” (2), we mentally imagine a parallepiped, in which the “slide” (2) in area in each of the body projections (side and rear views) occupies at least 70% (see photo). If the slide is too steep, we’re not shy, we climb onto the body and make it more gentle. We go down from heaven to earth and measure the height.
In this case, the height is: 0.28m + 0.35m \u003d 0.63m.
We determine the volume of the parallelepiped (2) by multiplying the length, width and height. As a result, we get the volume of firewood in the box in bulk:
Vpp \u003d 3.6m * 2.2m * 0.63m \u003d 4.987m3
To obtain the volume of firewood in bulk occupied by the "slide" (2), we multiply the resulting value by 0.7:
V (2) \u003d 4.987m3 * 0.7 \u003d 3.49m3
Multiplying the obtained value by the conversion factor, we get the number of firewood storage meters in the "hill" (2):
Vcl (2) \u003d3,49m3* 0.78 \u003d 2.72 squ.meter
Total, we get that according to our rough calculations, in the specified body is:
Vskl\u003d Vcl (1) +Vcl (2) \u003d3,707 + 2.72 \u003d 6.43 meter
which corresponds to reality within the margin of error (0.5-0.6 cells a meter) for the proposed method, since there are at least 6.3 oak wood storage meters in the back of the car shown in the photo.
The error of the calculation methodology is 10-12%, however, it allows you to tentatively determine the volume of the machine loaded with firewood with an accuracy of 0.5-0.7 squ.meter.
Attention: the above approach to determining the amount of firewood in the car body can be used only as an indicative or approximate for value perception.
Kamaz 5511 body volume has 6.6 cubic meters, it rightfully took the main place on the roads of Russia. Popularity provides him with increased cross-country ability and excellent maneuverability. The body volume of KAMAZ 5511 and the affordable rental price allows you to transport any bulk materials for both construction needs and agricultural work.
Kamaz today
There has been an increase in sales of cars - dump trucks, it reaches a high level today, however, the 55111 Kamaz dump truck quite harmoniously combines the necessary criteria, allowing any buyer to decide on the purchase of the necessary truck with a high level of reliability, and a very reasonable price, excellent performance and excellent quality.
Visually, such a truck resembles a dump truck, which has long established itself 5511, but is very different in carrying capacity. The mass of bulk cargo that such a truck can carry is 20 tons. Tipper body volume 4 cubic meters, this task can not cope.
Experienced drivers only speak favorably about KamAZ freight transport. The equipment was initially highly appreciated because of the 6x4 wheel formula, it has two driving axles, powerful wheel gears, a balancing trolley, plus very convenient disc wheels equipped with camera tires
The 55111 dump truck is an improved modification of the 5511 truck, the volume of the dump truck is 6.6 cubic meters. As soon as he appeared in 1988, the car immediately became one of the most popular machines for construction work in the country. It is reliable and practical, very convenient in maintenance and operation - it combines the characteristics necessary for working equipment.
The main purpose of KamAZ dump trucks is the transportation of bulk cargo of industrial or construction nature. Kamaz mammoth cars body volume of 20 cubic meters (photo below) is actively used in quarries, in the development and mining of minerals, smaller models are used in construction work and for agricultural purposes. 
Mammoths are dump trucks, models 6520. They have a large body volume of KAMAZ 6520, have a high carrying capacity of 20 tons, and a wheel arrangement of 6x4. Their total mass 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 and unique development. The KAMAZ 6520 car body volume of 20 cubic meters is designed to transport a variety of construction or industrial materials on roads that allow vehicles to travel with a maximum axle load of 10-13 m 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 its equipment with an articulated frame. There are models that have three axles (six driving wheels). An example would be the body volume of a Scania dump truck of 22 cubic meters. In addition, in modern models, it is possible to turn off the cross-axle differential.
Mining dump trucks (off-road dump trucks) are used where open-cast mining of any mineral resources is available. Today, the most common is a biaxial rear-wheel drive scheme, equipped with a rear unloading system. Maz truck dump body volume of 21cub and carrying capacity of 30 tons also proved to be quite good in career work. In the course of experiments in quarries using triaxial dump trucks, such a system was recognized as extremely uncomfortable. For large volumes, Belaz cars can be used, however, such heavy machines are completely inapplicable in urban and rural areas, and moreover, the body volume of the MAZ dump truck allows its use in the city as an easy and medium tonnage truck.
The use of dumping road trains helps to 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 maz dump truck, the body volume of which does not allow you to take all the cargo in one trip, then the road train will have a big advantage:
Firstly, excessive load (overload) on the equipment is eliminated, which reduces the risk of increased wear and premature breakdowns
Secondly, the transported volume (and weight) of cargo increases during one trip, which the operating instructions and the body volume of a single dump truck will not allow.
The main advantage of small-tonnage KAMAZ trucks, for example, KAMAZ truck body volume m3 are relatively small dimensions, which allow you to move in the conditions of narrow city streets and narrow roads of horticultural associations. The advantages of such special equipment of all models include the simplicity and reliability of the body structure, a good tipping angle of the platform (up to 60 °), excellent visibility from the cab, in addition, road stability, good handling, an economical fuel system.
Parameters Kamaz-5320
KAMAZ 5320 onboard tractors with a body volume of 9.8 cubic meters were produced at the Kama Automobile Plant and were designed to work with trailers. The body of the model 5320 is a metal platform, which opens the side and rear sides. The flooring on the floor is wooden, it is envisaged to install the tent with your own hands. The body volume of KAMAZ 5320 allows you to transport containers and goods that go beyond the dimensions of the car in height or length (for example, pipes) in compliance with traffic safety rules (SDA)
Device features
With a platform volume of 6.6 cubic meters, the 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, this allows you to transport goods even in cold conditions, without freezing cargo to the body. Unloading at the dump truck is done 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 tipping of the cargo platform.
Specifications
The 55111 dump truck is equipped with a turbocharged diesel engine and has an intercooler system. The power unit has a power of 240hp and meets the high Euro-2 standards. The volume of the fuel tank is 350 liters, the consumption of diesel fuel is 30 liters per 100 kilometers. The transmission has a ten-speed manual, with remote control.
Gas-53
Since the 60s of the last century, the factory, called today the GAZ Group, has begun production of new medium-tonnage trucks. They installed the latest (for that period) power units, transmission units, controls, body and cab.
Modifications
The GAZ-53 car was a mass production machine of the Union republics. 4 million cars were operating throughout the country in their usual, as well as tipper and specialized versions.
In the period 1961-1967, the GAZ-53F was produced. It was equipped with a six-cylinder engine with a power of 82hp. from GAZ-11, with a four-speed gearbox, it provided transportation of 3,500 kilograms of cargo, fuel consumption of 24 liters per 100 kilometers of low-octane gasoline. By the time the model was manufactured, there was no V-shaped powertrain in production.
For the 53F model, the GAZ-11 six-cylinder engine was boosted, while the compression of the mixture increased. A hypoid rear axle was not invented either, so the mechanism from the 51A model with bevel gears was supplied.
In fact, gas 53 dump truck body volume 4.8 cubic meters of model F, according to its technical characteristics it was a transitional (intermediate) model between such series as 51A (with a loading capacity of 2500 kilograms) and SAZ-53B (carrying capacity was increased by a ton), this was achieved by increasing to 3 , 7 meters of base and the installation of new 8.25-20 tires, which are mounted on steel disks.
The car was used not only as a dump truck, a sewage truck, milk tankers and fuel trucks were common. 
The GAZ-53 car was not a complete design, due to constant breakdowns of machine parts, it did not become popular either among drivers or among employees of various repair services and motor transport enterprises. Such a truck was equipped with a noticeably weak engine, had an unreliable bridge and was produced until 1967.
In the period 1964-1983, models from the 53 and even 53A series appeared on the roads, having a cargo load of 3,500 and even 4,000 kilograms. They installed a more powerful motor of the ZMZ-53 brand, with a capacity of 115 hp, which ensured an increase in speed up to 85 km / h with a fuel consumption of 25 liters per 100 kilometers. The body volume of the gas dump truck 53 has not changed.
Differences modification 53A from the previous
Model 53A has the following differences:
- Reinforced front axle
- Increased steering reliability
- Improved drive shaft design
- Turn signals are duplicated using repeaters on the wings of his cockpit.
- New form radiator grill installed
- Wipers equipped with electric drive
- Equipped with cab heating
Model 53A in 1973 was awarded the USSR State Quality Mark. To expand the functionality of the machine, the manufacture of the chassis model 53 01 for covered bodies and special equipment was established.
The chassis of model 53 02 was a platform for the body of the dump truck and was equipped with a unit for power take-off on a hydraulic pump.
Trucks 53 50 and 53 70 were produced for export. Cars were readily purchased in Finland, Belgium. In Cuba and Bulgaria, trucks were assembled from kits that came from GAZ.
Car 53 12 was produced in the period 1983-1992, this is a further development of the 53rd line. In the trucks, the ZMZ-511 motor was installed, which had 8 cylinders. Power parameter 120 hp It allowed a load of up to 4.5 tons, and a speed indicator of up to 90 km / h.
Gasoline consumption increased to 30 liters, but it was possible to install equipment for the engine to operate on natural gas.
