The Belarusian-made dump truck MAZ-5551 has been occupying one of the dominant places in the market of this special equipment for more than 30 years. During the period of operation, the unit has repeatedly demonstrated technical capabilities that set it apart from other models. The large dump truck is distinguished by its amazing maneuverability for its weight. The technical characteristics of MAZ 5551 ensure the demand for this model among domestic and foreign buyers.
MAZ scope
The technical characteristics of MAZ-5551 make it a versatile vehicle. The basic purpose of the truck is work related to transportation. MAZ is used for the transportation of agricultural bulk products and building materials.
In the construction industry, the unit is used not only as a truck, but also as a special vehicle for the maintenance of buildings and road surfaces... The model's amazing maneuverability allows it to adapt to any site configuration. This parameter also affects the demand for MAZ in construction.
Special specifications the bodies of the unit allow transporting construction cargo in the form of sand, crushed stone and gravel. The truck is often used to remove construction waste from sites. The model has also established itself as a reliable grain carrier.
General machine parameters
The technical characteristics of MAZ-5551 reveal the great power potential of this unit. The robust supporting frame of the vehicle allows it to carry out large-scale cargo transportation operations. Wheel formula 2 * 4 expands the range of angles possible turn... The four-stroke engine of the dump truck is located under the driver's cab and is easy to maintain and operate.
The dump truck has the following characteristics:
- length- 5900 mm;
- width- 2500 mm;
- height- 2900 mm;
- weight (full)- 17620 kg;
- lifting capacity- 10,000 kg;
- wheelbase length- 3960 mm;
- roominess cargo compartment - up to 12 m 3;
- front wheel pressure- 5980 kg;
- rear axle pressure- 10200 kg;
- total turning radius- 8.6 m;
- fuel consumption- 22 l / 100 km;
- fuel tank volume- 200 l.
When the body is completely filled, the main load is distributed to the rear axle. The maximum carrying capacity of the vehicle is 8500 kg. The chassis of the vehicle withstands the pressure of the vehicle's multiple power mountings. The cabover-free driver's cab easily reclines and opens up space for comfortable engine service.
MAZ-5551 has a high level of mobility. Sustainable chassis the car allows you to tilt the body in various variations. The all-metal body is adjustable to the desired level of inclination. The machine is unloaded using a hinged rear cover.
Some modifications of the machine have a three-way unloading, as well as a special heating installation, operated when low temperatures(up to -60 o). Maximum angle lifting the cargo compartment - 50 o. Within one minute, the dump truck can accelerate to a speed of 60 km / h. Maximum speed the movement of the truck is 85 km / h.
Technical characteristics of the motor and accessories
The MAZ-5551 dump truck is equipped with powerful engine domestic production... The six-cylinder YaMZ-236M2 engine guarantees smooth operation machine for a long time. Torque (max - 882 N / m) allows the truck to cope with the most rugged terrain. The total engine power is 230 hp. With. The latest MAZ modifications are equipped with a system of additional reinforcements that stabilize surges in operation.
Brake system
The MAZ-5551 brake system is a drum pneumatic mechanism that simultaneously controls the front and rear wheels... The rear axle is attached to the frame with a suspension. Additional suspensions act as shock absorbers that absorb pressure from the external environment in a two-way mode.
Transmission
The YaMZ-236P mechanical gearbox is also a domestic mechanism that includes 5 control steps. The first versions of this element in the MAZ-5551 dump truck differed in the possibility of low load, but the latest technical transformations brought this device to a new level.
YaMZ-236P gearbox - device
Hydraulic system
The hydraulic system of the unit has technical characteristics that ensure smooth movement of the passenger compartment and cargo compartment. It is a hydraulic pump mechanism with cylinders. The cylinders are equipped with safety valves that prevent the body from overloading. The opening and tilting of the cargo compartment is carried out remotely by the driver from the cab.
Safety system
Additional safety systems for the MAZ-5551 truck include the design of stabilizers that increase the stability of the wheels and the entire vehicle as a whole. Cardan transmission realizes torque using needle bearings. Electrical wiring protected by an internal voltage regulator, which is presented as rechargeable batteries... The power steering also makes driving safer and more stable.
The device of the cab and driver's seat
The design of the driver's cab MAZ-5551 is technologically advanced. For 30 years of production of the model, the developers have carried out several small transformations regarding the shape of the headlights and side windows. However, the driver's space meets basic comfort characteristics. Inside the cab are installed: air conditioner and heater.
Handrails and steps attached to the main frame are ergonomically designed for maximum comfort and ease of climb into the cab. The command panel is a compact set of levers and control buttons. The driver's seat is adjustable and the passenger seat is fixed directly to the floor.
This part of MAZ-5551 is equipped with compartments for storing personal items between the driver's and passenger's seats. Extended panoramic windows allow the driver to view the jobsite and windshield helps to track the tilt of the body.
Dump truck MAZ-5551
Without the MAZ-5551 dump truck, it is impossible to imagine any construction site in Russia. This hereditary “handyman” has been successfully transporting goods for a long time. Considering that its direct descendant MAZ-503 entered the line in November 1958 and did not change too much, having received a new code in 1985, then its history goes back almost 50 years.
The popularity of the MAZ-5551 dump truck is very wide and justified. Transporting bulk cargo over short distances, it has no competitors in terms of price and “work capacity”. Some experts draw parallels comparing it with our ZIL-MMZ-4520 and KAMAZ-65115, but this comparison is not entirely justified, since “our” dump trucks are designed for long-distance transportation. Wheel formulas, incorporated in the design of 6x4 for ZIL and KAMAZ, and 4x2 for MAZ, immediately determine this difference. Confidence in the narrowness of construction sites is given by spent steering equipped with high-quality hydraulic booster... MAZ is very easy to deploy in two steps on the narrow temporary roads of construction sites.
The appearance of the dump truck is not burdened modern design, but the most convenient for work. Nothing extra. During the transition to the production of MAZ-5551, a very important drawback of its predecessor was taken into account, associated with the “unfastening” of the cab. The spring mechanism was replaced by a hydraulic drive, which eliminated the risk of abnormal "unfastening" in the event of spontaneous opening of the locks. To finally insure this operation, the developers have complicated it by the need to open the radiator grille using a mounting. The cabin is double, but very spacious. Between the seats there is a convenient shelf for documents and necessary things. There is only a cigarette lighter and an ashtray - at MAZ "for a healthy lifestyle".
The driver's seat is sprung. However, according to the MAZ-5551 drivers, it is not very convenient. The passenger seat is firmly attached to the floor. Considering that the cab does not have shock absorption at the attachment points, the entire rigidity of the suspension directly affects the comfort of the seats for both the driver and passenger. Wheel together with the adjustable steering column, they also do not bring a feeling of comfort. The dashboard meets the working standard. The only drawback is the weakness of the light indication.
Speaking of technical characteristics, the base MAZ-5551 is equipped with a 180-horsepower YaMZ-236M2 engine, equipped with a 5-speed YaMZ-236P gearbox. Fuel tank with a capacity of 200 liters. On modifications, a more advanced one can be installed. power unit YaMZ-6581.10 with a YaMZ-2361 box or even Deutz BF4M1013FC with a ZF 6S850 box. The carrying capacity of this car is ~ 10 tons.
The MAZ-5551 dump truck is equipped with an all-metal body with rear unloading. However, the modifications are equipped with unloading systems that allow unloading on three sides. Convenient underbody heating system allows you to work effectively in winter time... Stabilizer mounted behind the rear axle lateral stability gives the truck confidence when entering corners when loaded. The pneumatics of the brakes work reliably. The only drawback is the long download of the system.

This most massive model of maneuverable dump trucks is working hard on all construction sites in the country. Dump truck MAZ-5551 is designed for "short shoulder". It is irreplaceable in urban construction.
General look MAZ 5551
The photo presented here shows a version of the truck, which received a radically changed cab. Its outlines have lost their former roundness, giving way to clear edges. The former forked windshield of the truck has given way to a large curved panoramic triplex. The cab roof has been decorated with a new spoiler that reduces fuel consumption. The headlights have undergone creative changes.
Over the years, the technical characteristics of vehicles have been continuously improved. The photos show: the bonnet arrangement with two-stroke units gradually disappeared from the conveyor, and its place on the conveyor was taken by its own project MAZ-500.
Since that time, many modifications of this prototype have rolled out of the gates of the enterprise. The video highlights the MAZ-503 dump truck, the predecessor of the MAZ-5537 model. The project formed the basis for the modification of the MAZ-5551.
Model line
The development turned out to be so successful that a number of modifications were created on its basis:
- Maz 5550... It represents the next version of these agile trucks. Maz 5550 is equipped with an engine (435hp), which works in tandem with 6 stepped box speeds. As fuel, Maz 5550 consumes fuel that meets the Euro-4 environmental standard;
- Maz 555102... The truck has an engine with a capacity of 230 "horses". Thanks to a more impressive unit, MAZ 555102 has a good acceleration speed.
Speaking of technical subtleties, it should be noted that an increase in the power of the engine installed on the Maz 555102 became possible with the use of turbocharging. Intermediate air cooling is carried out.
The advantages of MAZ 555102 show themselves well in city traffic. Even under unfavorable temperature conditions, MAZ 555102 confidently moves through the streets on high speeds... In addition, Maz 555102 consumes less fuel;
- Maz 555142... This modification differs from the prototype in that MAZ 555142 works in tandem with a trailer. The carrying capacity of such a road train is significantly higher;
- Maz 5551a2... The road train is positioned as a grain carrier. Maz 5551a2 is capable of unloading to the left, right and back. In other words, MAZ 5551a2 consists of a main dump truck and an additional trailer. Both cargo tanks are equipped with higher sides. The complete set of maz 5551a2 is supplemented with an awning and a rear removable canopy;
- Maz 5550v2... The dump truck is capable of transporting bulk cargo, the weight of which does not exceed 10 tons. Maz 5550v2 attracts compact dimensions and excellent maneuverability. It works well in confined areas, fuel efficient. Reinforced suspension adapted for off-road use.
About the interior, exterior and ergonomics of MAZ 5551
The description of the cab of the Minsk "long-liver" should begin with the fact that it is much more spacious than the KamAZ salon. The advantageous location of steps and handrails contributes to increased comfort. Thanks to this, the driver can easily climb into the driver's seat.
Despite the fact that the steering columns have two-plane adjustment, and the driver's seat moves on a sled, the driver is in an uncomfortable position. And although the visibility remains good, there is an increased driver fatigue, which is especially dangerous on long-distance routes.
The photo shows that the dimensions of the steering wheel are unnecessarily large. In order to make a turn, a small driver is forced to make regular forward bends.
The dump truck is equipped with a convenient and sufficiently informative dashboard. However, there is a "but" here: the light indication is not bright enough, therefore, in the daytime, the devices are poorly viewed.
And yet, there are much more successful design solutions in the cab of the MAZ-5551 dump truck than misses (as evidenced by positive reviews). The layout of the block, in which the fuses and relays are located, is successful. It is located behind the dashboard, closer to the passenger seat. An easy-to-open hatch is mounted on top of it.
The design has also changed. parking brake... If earlier these trucks were equipped with drum handbrakes, then in the current layout of the MAZ-5551 (as well as the MAZ-555102) there are brake chambers and spring accumulators.
The level of comfort of the interior space of the cabin is provided by many additional options presented in the video:
- a ventilation hatch on the roof;
- interior lighting shade;
- efficient heating system.
MAZ cabin is equipped with a single passenger seat. The space between him and driver's seat filled with a shelf in which you can store documents, bottles and other trifles. The imposing exterior mirror blocks provide excellent visibility.
In addition to adjustment systems, the driver's seat has suspension units. The MAZ cab lacks real comfort, because it is attached to the frame directly, without shock absorbers. There is no need to talk about the passenger seat at all: there are no adjustments in it, it is rigidly mounted in the passenger compartment floor.
The video shows a hydraulic drive that raises the cab, revealing the power unit for viewing. Such a unit is more reliable in comparison with a spring system, which can swing back at the most inopportune moment when the lock breaks. To now raise the cab, it is necessary to open the radiator grille and get to the "assembly", which activates the mechanism.
Technical part: driving properties of the MAZ 5551 dump truck
To determine the technical qualities of the MAZ-5551 dump truck, a run of about 900 kilometers was completed. According to the test results, there were some comments.
The gearbox installed on the truck has good selectivity, but the gearshift takes place with noticeable effort. To carry out the transition of gears "down" or "up" is applied double squeeze clutch (coupled with rebase). The entire cycle is carried out precisely and gently.
Fully loaded (10 tons), the MAZ-5551 dump truck is very difficult to get under way in first gear. This speed is quite short and the acceleration dynamics is extremely low.
If the truck is on a flat track, then even full mass a dump truck of 17 tons does not prevent him from calmly starting movement even from second gear.
At full load, the truck develops cruising speed about 90 km / h. However, even the fifth gear keeps the truck speed within 40 km / h. At the same time, fuel consumption does not exceed the limits specified in the manual. The steering wheel of the car is equipped with an uninterrupted hydraulic booster, thanks to which the car moves quite briskly.
The model impresses with its excellent maneuverability. Photos prove that the dump truck is capable of making a full U-turn, even on the narrowest roads. Behind rear axle a stabilizer is installed to provide lateral stability. Thanks to this, the heavily loaded vehicle can confidently take turns.
The truck has pneumatic brake units. An efficient system has the only drawback: the air is pumped too long. This is due to the insufficiently powerful compressor.
Such disadvantages are quite understandable for inexpensive models... For the cost of the MAZ-5551 dump truck (like the MAZ-555102) is much less than the prices at which similar foreign cars are sold, on board which there are all sorts of additional components and options (and spare parts are easier to find).
Summarizing all that has been said, the following can be noted. The Maz 5551 dump truck was put on the conveyor more than a quarter of a century ago. The country in which the production of these machines began has sunk into oblivion. Despite this, the project survived in difficult times and has survived safely to this day (even second-hand copies work with dignity). This was facilitated by flexible management and effective work of the Minsky team. automobile plant, whose brainchild is MAZ-5551.
In the vastness of the large Soviet country, MAZ-5551 participated in almost every construction and other spheres of the national economy.
The USSR no longer exists, and this dump truck continues to be produced and modernized in the already independent states.
The model is assembled at the MAZ automobile plant in Minsk.
What makes this truck so popular and in demand for such a long time, despite the abundance foreign analogues and competitors?
The history of development
The Belarusian "hard worker", as he is called, began his life in the war years after the liberation of Minsk.
The Bialowieza bison became the emblem of the brand. With the development of production, MAZ-500 was created - the main progenitor of the modern MAZ-5551. It happened in the late 60s.
The dump truck has become own development Minsk designers. It was aggregated with a YaMZ-236 engine, which was already four-stroke.
After a series of modifications and improvements, in 1985 one of the versions, the MAZ-5551 dump truck, entered serial production. It is the most common in Russia.
An important advantage of the "Belarus" is its agility and maneuverability due to the small wheelbase of the truck and the two-axle configuration.
Therefore, in urban environments, it fits perfectly even into small construction sites and turns.
Description of the base model dump truck and its modification 020
The only difference of modification 020 is the increased volume of the loading part due to the change in the initial height of the sides. The rest of the characteristics are identical.
Engine
The heart of this truck is the V6 diesel engine.
The YaMZ-236M2 (Yaroslavl) copes with its duties perfectly, fulfilling the load without tears and complaints.
Torque of 667 Nm and 180 hp. With. more than enough to get a loaded dump truck out of difficult situations.
In the latest versions, the plant installs YaMZ-6563.10, YaMZ-6581.10 (shown in the photo on the left) or Deutz BF4M1013FC.
According to the technical characteristics, the power of these units is higher than that of the older model. In addition, MAZ keeps up with the times, and latest motors meet the Euro 3 standard, which significantly expands the possibilities of their application.
Transmission and drive
The MAZ-5551 dump truck is equipped with a 5-speed manual gearbox... Its technical characteristics cannot be called ideal.
Under severe loads, first gear is too short and it is very difficult to move the truck on unstable ground.
But on flat road engine and gearbox match perfectly and move a loaded dump truck with ease. The maximum speed is 90 km / h. The rear axle is the driving axle, corresponding to the 4x2 drive type.
However, a major improvement in gear shifting was the redesign of the gear shift mechanism from the lever to the box. This made it possible to significantly shorten the lever itself.
All innovations made life easier for the driver, because earlier, to "catch" the right gear, the scrap-like lever had to be “pulled” throughout the cab, but now this process has become easy and enjoyable.
Carrying capacity
Reliable power steering does its job well. Thanks to the anti-roll bar, the car feels confident when cornering, especially when fully loaded.
Another advantage is the pneumatic brakes. They are very reliable and time-tested, such an important safety element is made by the manufacturer at a height.

Convenience and comfort
What did the designers do for the ergonomics and convenience of the driver and passengers in MAZ-5551?
Unlike previous version still in the design and location of controls, driver's seat and dashboard made some pleasant changes, which, of course, added comfort and ease of use.
The cockpit is spacious and comfortable. Without a berth, the driver and two passengers are easily accommodated here.
The cab is easy to climb thanks to correctly positioned handrails and steps. The ergonomics of the arrangement of the elements of the cab can hardly boast of.
The steering wheel is adjustable both in departure height and in tilt angle. The seat moves on a sled. Still, it is difficult for the driver to find a comfortable position for himself.
This leads to quick fatigue and negatively affects the concentration and quality of his work.
The steering wheel is too big, and in order to turn it, a bare driver needs to constantly move his body forward towards it, which can hardly be called convenience.
However, thanks to the large side mirrors and the driver's position, the visibility remains at a height.
The dashboard is quite informative, but due to the weak brightness of the light indication of some indicators, individual elements are poorly visible during the day.
But nevertheless, the Belarusian creators tried to transform the cockpit in many ways and inner space... And they did it.
The location of the safety box has become successful - behind the dashboard near the passenger seat, access to it is not difficult.
The next indicator of comfort can be called good and efficient heating, which, even in severe frosts, copes with its function.
The lighting and ventilation of the cab are made at a high level.
There is a special compartment between the driver and passenger, in which you can put, for example, documents, a bottle of water and other small things.
There is also a cigarette holder here, but for some reason the developers of this car did not foresee either a cigarette lighter or an ashtray.
The sprung driver's seat compensates for the lack of a cab damping system that is directly attached to the frame. But the passenger seat is rigidly attached to the floor and devoid of any adjustments.
It is inconvenient to open doors from the inside due to the low position of the opening lever.
To overturn the cab, the designers of MAZ took into account the shortcomings of the spring mechanism, which could create a hazard due to spontaneous snap-off and tilting, and equipped it with a hydraulic drive.
It is thanks to this system that the danger inherent in the spring lock is cut off. For the domestic market trucks all hydraulic drives are interchangeable.
MAZ can also be called domestic, since it was originally made in one big country- THE USSR. The fixing system is very simple - a steel cable is attached to the frame and to a point at the bottom of the cab.
Although not aesthetically pleasing, it is cheap, reliable and practical. The hydraulic cab tilt control is located under the radiator grill.
This arrangement is due to the fact that the driver remembers that it is impossible to raise the cab without an open radiator grill.
The quality of the body metal and the elements themselves are not as reliable as we would like, but this does not prevent the use of the car as a tractor.
The handbrake on the MAZ-5551 is of a modern design with spring-type power accumulators, has good technical characteristics.
A significant miscalculation of the system, according to experts, is the absence of bolts in the chambers, with which you can forcibly release the pads.
Varieties
There are often different versions of MAZ-5551, such as the 020 with an increased load.
MAZ-5551-020R is equipped with an even larger loading surface and volume.
MAZ-555102 has three configurations - 220, 223, 225. The series is equipped with 230 hp engines. With.
Model 225 is equipped with a dump truck with three-way unloading and the possibility of articulation in a road train. Carrying capacity 9,500 kg, 220th and 223rd versions - 10,200 and 10,100 kg, respectively.
The most modern and technologically advanced engines are equipped with MAZ-5551W3-425-000 (E-4) and MAZ-5551R7-425-000 (E-4), which meet environmental standards Euro 4 and have a capacity of 245 and 250 liters. With. respectively.
Optionally equipped with air conditioning, engine heater, interior heater, sideboards, awning, electropneumatic hydraulic outlets for the trailer, rear bumpers and side rails.
What are the advantages
In conclusion of the review of the MAZ-5551, one can note the persistence and desire of the Belarusians to keep up with the times and thereby stay afloat in the competition with imported brands.
During the crisis in the post-Soviet era, many auto enterprises closed and ceased to exist, but MAZ survived and developed production to world standards, now competing with the rest.
Of course, listing the main miscalculations and shortcomings of MAZ-5551, we must not forget that its price is many times lower than imported ones, which are full of various technological equipment and capabilities.
Important! For example, model MAZ-5551 A2-325 of 2013 can be purchased for 760,000 rubles.
Millions of drivers in the CIS countries perceive MAZ as very true friend, who, both in the heat and in the cold, will bring them home, despite his, perhaps, insufficient comfort and convenience. He is rightfully awarded the popular nickname "workaholic".
In the vastness of the large Soviet country, MAZ-5551 participated in almost every construction and other spheres of the national economy.
The USSR no longer exists, and this dump truck continues to be produced and modernized in the already independent states.
What makes this truck so popular and in demand for such a long time, despite the abundance of foreign analogues and competitors?

There is a special compartment between the driver and passenger, in which you can put, for example, documents, a bottle of water and other small things.
There is also a cigarette holder here, but for some reason the developers of this car did not foresee either a cigarette lighter or an ashtray.
The sprung driver's seat compensates for the lack of a cab damping system that is directly attached to the frame. But the passenger seat is rigidly attached to the floor and devoid of any adjustments.
It is inconvenient to open doors from the inside due to the low position of the opening lever.
To overturn the cab, the designers of MAZ took into account the shortcomings of the spring mechanism, which could create a hazard due to spontaneous snap-off and tilting, and equipped it with a hydraulic drive.
It is thanks to this system that the danger inherent in the spring lock is cut off. For the domestic truck market, all hydraulic drives are interchangeable.
MAZ can also be called domestic, since it was originally made in one large country - the USSR. The fixing system is very simple - a steel cable is attached to the frame and to a point at the bottom of the cab.
Although not aesthetically pleasing, it is cheap, reliable and practical. The hydraulic cab tilt control is located under the radiator grill.
This arrangement is due to the fact that the driver remembers that it is impossible to raise the cab without an open radiator grill.
The quality of the body metal and the elements themselves are not as reliable as we would like, but this does not prevent the use of the car as a tractor.
The handbrake on the MAZ-5551 is of a modern design with spring-type power accumulators, has good technical characteristics.
Do you know the release of which fell on the period from 1964 to 1999?
And you can get acquainted with the technical characteristics of the car GAZ-33081 "Huntsman".
A significant miscalculation of the system, according to experts, is the absence of bolts in the chambers, with which you can forcibly release the pads.

What are the advantages
In conclusion of the review of the MAZ-5551, one can note the persistence and desire of the Belarusians to keep up with the times and thereby stay afloat in the competition with imported brands.
During the crisis in the post-Soviet era, many auto enterprises closed and ceased to exist, but MAZ survived and developed production to world standards, now competing with the rest.
Of course, listing the main miscalculations and shortcomings of MAZ-5551, we must not forget that its price is many times lower than imported ones, which are full of various technological equipment and capabilities.
Important! For example, model MAZ-5551 A2-325 of 2013 can be purchased for 760,000 rubles.
Millions of drivers in the CIS countries perceive MAZ as a very faithful friend, who, in the heat and cold, will bring them home, despite his, perhaps, insufficient comfort and convenience. He is rightfully awarded the popular nickname "workaholic".
After the technical characteristics of MAZ-5551 have been studied, we suggest that you familiarize yourself with the external features of the car:
