MAZ 551603 221 - dump truck (technical characteristics). Maz 555102

There was still about a year left before the end of the Great Patriotic War, Belarus was completely destroyed... And in Minsk, liberated from the occupiers, construction of a new plant began. Where German workshops were previously located, the construction of the first workshops of the future car assembly plant began.

The needs of the front were a priority - practically in the open air, “screwdriver” assembly of American GMCs and Studebakers, which were supplied from the States under Lend-Lease, was carried out. The production of these trucks ceased immediately after the end of the Second World War, since the main forces were aimed at creating their own cars. The first five cars were assembled in the fall of 1947. These were the famous MAZ-205, the base model for which was the YAZ, which laid the foundation for a whole generation of Belarusian cars. The symbol of the new trucks is the famous Belovezhskaya bison.

In parallel with the production of cars, the construction of factory workshops was underway, and already in 1948, serial production of trucks became possible - the first stage of the plant was commissioned. After the commissioning of the second stage in 1950, it was possible not only to meet the planned capacity, but also to exceed it. In 1951, Minsk residents produced 10,000 more cars than expected (25,000 instead of 15,000).

MAZ-555102: general information about the car

The MAZ-555102 dump truck with a lifting capacity of 10 tons is based on the MAZ-5337 two-axle flatbed truck. The production of the dump truck began at the Minsk Automobile Plant in 1985 and is still being produced. The dump truck chassis can be supplied without a body and a tipping mechanism for installation by third-party companies of various equipment (concrete mixers, vehicles for removing waste in containers).

general description

MAZ-555102 is equipped with an all-metal body with a useful volume of 12.5 cubic meters; it is designed for transporting bulk non-metallic cargo. For unloading, the body is tipped using a hydraulic mechanism. A single cylinder is installed on the frame cross members, connected by a hinge to the base of the body. Drive of the hydraulic system from the power take-off and pump. A tank with 25 liters of oil for the system is installed on the frame side member. Unloading can be carried out in three directions, the direction is selected by a pneumatic switch on the control panel.

On the rear cross member of the frame there is a towing device for a dump trailer. This version of the dump truck is used when transporting agricultural goods.

The basic equipment of the car can be expanded with additional equipment. The list of options includes a creeper in the gearbox, monitoring and (or) fuel consumption recording systems. To improve the characteristics of the MAZ-555102, it can be equipped with standard extension sides of the body with a height of 300 mm. In this option, the useful volume of the platform increases by 3 cubic meters.

Chassis

The car's suspension is mounted on semi-elliptical longitudinal springs. Shock absorbers are additionally used in the front suspension design. The rear suspension uses double leaf springs and an anti-roll bar.

Drum-type brake system with pneumatic drive. To increase reliability and safety, the front and rear axle brakes have a separate drive. Additionally, a compression-type engine brake is installed, powered by rotary flaps in the engine exhaust system. Next to the towing device there is a connector for connecting the pneumatic system. An anti-lock braking system and a speed limiter are available upon request.

Engine and transmission

The dump truck is equipped with a diesel engine model YaMZ-236NE2 with a power of 169 kW. The engine is mated to a five-speed YaMZ-236P gearbox or an eight-speed gearbox model 2361 (optional). This power unit provides acceptable technical characteristics of the MAZ-555102 - the vehicle reaches speeds of up to 85 km/h with an operating fuel consumption of within 26 liters per 100 km (at a speed of about 60 km/h).

At the buyer's request, an autonomous heater PZD-30 is installed on the dump truck. The use of such a device ensures trouble-free engine starting at low temperatures (below minus 20 degrees). The operating principle is based on heating the coolant and oil in a special boiler, heated by the flame of the heater burner. To circulate coolant, an additional pump is installed on the engine. To install the heater, a standard place is provided between the bottom of the radiator and the engine sump.

To transmit torque, a cardan shaft with an intermediate support is used. The rear axle has a double transmission - the main gearbox and planetary gearboxes in the wheel hubs.

Operational characteristics of MAZ 555102 dump trucks

There was still about a year left before the end of the Great Patriotic War, Belarus was completely destroyed... And in Minsk, liberated from the occupiers, construction of a new plant began. Where German workshops were previously located, the construction of the first workshops of the future car assembly plant began.

The needs of the front were a priority - practically in the open air, “screwdriver” assembly of American GMCs and Studebakers, which were supplied from the States under Lend-Lease, was carried out. The production of these trucks ceased immediately after the end of the Second World War, since the main forces were aimed at creating their own cars. The first five cars were assembled in the fall of 1947. These were the famous MAZ-205, the base model for which was the YAZ, which laid the foundation for a whole generation of Belarusian cars. The symbol of the new trucks is the famous Belovezhskaya bison.

In parallel with the production of cars, the construction of factory workshops was underway, and already in 1948, serial production of trucks became possible - the first stage of the plant was commissioned. After the commissioning of the second stage in 1950, it was possible not only to meet the planned capacity, but also to exceed it. In 1951, Minsk residents produced 10,000 more cars than expected (25,000 instead of 15,000).

Popular Belarusian trucks

From this time on, the active development of the enterprise and the constant increase in production capacity began. Almost 30 years after the release of the first trucks, the model range was replenished with a new product - in 1976, the first dump truck rolled off the plant’s assembly line. Currently, the line of MAZ dump trucks is quite wide, and the plant is constantly working on creating new models and improving existing ones. In turn, this makes it possible to select an option that best suits the nature of the tasks being performed.

Dump trucks of the Minsk Automobile Plant are extremely popular not only in their homeland, and the company itself is one of the recognized world leaders. In Russia, along with Kama trucks, MAZs occupy a large share of the special equipment market. And this is not surprising. After all, reliable and unpretentious MAZ dump trucks receive only positive ratings from consumers over a long period of operation. Adapted to difficult working conditions, the vehicles cope well with large volumes of work and have a wide range of applications. Construction, agriculture, mining - this is an incomplete list of industries that successfully operate MAZ trucks.

The MAZ 555102 dump truck is a typical representative of the family of two-axle vehicles equipped with a dump body with a 4x2 wheel arrangement. The car does not differ in cross-country ability, but even on dirt roads it drives confidently. In addition, unlike trucks with a 6x4 wheel arrangement, this dump truck is more maneuverable. The smaller turning radius makes it easy to turn around in tight spaces. The main purpose of the vehicle is transportation and mechanical unloading of bulk cargo. The dump truck is suitable for transporting sand, clay, limestone, chalk, soil, garbage or snow.

Body Features

The MAZ 555102 cargo platform is an all-metal welded structure and, depending on the modification, can be either rear (model 555102-223 or -220) or three-sided unloading (model 555102-225). So the truck, with index 220, is equipped with a body volume of 5.4 cubic meters. and an area of ​​8.6 cubic meters. Body dimensions – 3,800 x 2,268 x 630 mm. Another model, index 223, is equipped with a cargo platform with an increased side height. Its overall dimensions are 3,800 x 2,268 x 950 mm, and its volume is 8.3 cubic meters. The platform area is 8.6 sq.m.

The 225 dump truck model is offered with two types of body. The standard platform has a volume of 5.5 cubic meters. and internal dimensions 3,800 x 2,400 x 600 mm. The platform with enlarged sides is more spacious, its volume is 7.7 cubic meters. The body is equipped with a telescopic hydraulic cylinder with retractable links. Thanks to the hydraulic drive, the platform can be raised and lowered directly from the cab.

Operating characteristics of the dump truck

As for the remaining technical characteristics of the MAZ 555102, they are similar, regardless of the modification of the vehicle. The overall dimensions of the dump truck are 6,000 x 2,550 x 2,950 mm. The curb weight of the vehicle is 8,500 kg. The permissible total weight of the dump truck reaches 18,200 kg. The carrying capacity of different models varies from 9.5 to 10 tons, which allows the transport to be used for any work, with the exception of those that require machines with a higher carrying capacity.

The YaMZ diesel 6-cylinder V-shaped engine complies with Euro-2 standards and has a volume of 11,150 cc. Its power is 230 hp and its maximum torque reaches 882 Nm/min-1. The installed power take-off provides the ability to redistribute engine power when the platform moves.

According to benchmark indicators, fuel consumption of MAZ 555102 varies depending on operating conditions. So, with an average speed of a dump truck of 60 km/h, the consumption is 24 liters per 100 km. ways. When driving as part of a road train, fuel consumption increases to 30 liters. The fuel tank of the car is designed for 200 liters.

The power unit is successfully combined with a simple and reliable manual transmission, also produced by the Yaroslavl Motor Plant. The total number of gears is 5. The car reaches a maximum speed of up to 90 km/h. When equipped with an electronic speed limiter, this figure drops to 85 km/h.

The cabin of the MAZ 555102-220 and -223 dump truck is of the small type and is designed for 2 people. The MAZ 555102-225 modification can accommodate three people. There is no sleeping space in these trucks. The interior design of the cabin is quite laconic, there is no need to talk about a high degree of comfort, but, in general, the working conditions are not bad. Good visibility, sound insulation, sprung driver's seat

There is no need to mention the reliability of Minsk trucks again. Of course, some elements fail and require replacement, but there should be no problems finding them. Any self-respecting company that sells auto parts will offer the necessary ones. You can view the MAZ 555102 spare parts catalog and even order what you need without even leaving your home. Just look into the online store and place an order.

The high degree of popularity of Minsk dump trucks is due not only to their optimal performance characteristics, but also to the plant’s affordable pricing policy. The price of MAZ 555102 starts from 350 thousand for used cars and reaches 750 - 900 thousand for models without mileage.

Availability of consumables and their cost

Maintenance of the MAZ-551605, the price of which varies depending on the year of manufacture and condition, plays a rather important role in the performance of all equipment as a whole. The further life of the vehicle and the service life of its key parts depend on systematic and correct maintenance. The main consumables are: lubricants for the engine, transmission and hydraulics, oil seals, seals, filtration elements, injectors, tires, etc. The cost of each part depends on many conditions, for example, one tire of size 12.00R20 costs about 15,000 rubles.

History of development

The construction of an automobile plant in Minsk, bloodless from the fascist occupation, began in 1944. At first, the plant repaired vehicles intended for the needs of the front, and after the end of the Great Patriotic War, in 1947, the first YaAZ trucks were assembled in the MAZ experimental workshop.

In February 1948, the first production model of the MAZ 200A truck went to Moscow for testing and approval by the USSR Ministry of Automotive Industry. It was this car that marked the beginning of the production of a whole generation of new Soviet heavy two-axle trucks. The emblem of the Minsk Automobile Plant, the Belovezhsk bison, perfectly personified the mighty strength and endurance of the Belarusian workers.

The design of trucks was constantly improved. By the early 60s, hooded trucks with two-stroke engines gave way on the assembly line to self-developed MAZ-500 vehicles with a four-stroke YaMZ-236 power unit located under the cab. Among the many modifications of this truck there was also a MAZ-503 dump truck, which was the predecessor of the MAZ-5537 model, on the basis of which the MAZ-5551 was developed.

MAZ-5551 being tested

In the new version of the truck, the cabin has undergone dramatic changes. The design of the headlights and radiator grilles has been changed, the shape of the cabin has acquired clear edges instead of rounded shapes. Instead of a split windshield, a curved panoramic windshield was installed on the truck. A new spoiler design was installed on the roof.

The attitude towards the design solutions used in the development of the truck can be twofold. On the one hand, most of the applied solutions can be called anachronism, on the other – time-tested solutions. Having tested a dump truck that just came off the assembly line, we are more inclined to the second approach. However, some components and structural elements certainly need to be updated and brought into line with modern requirements.

The country in which the first MAZ-5551 dump truck rolled off the assembly line many years ago has long been absent from the world map. The Russian Federation and the Republic of Belarus are sovereign, independent states. Unfortunately, many of the famous factories created during the years of the Soviet Union fell into disrepair and ceased to exist.

The Belarusian “hard worker,” as he is called, began his life during the war years after the liberation of Minsk.

The Belovezhsk bison became the emblem of the brand. With the development of production, the MAZ-500 was created - the main progenitor of the modern MAZ-5551. This happened in the late 60s. The dump truck was the own development of Minsk designers. It was powered by a YaMZ-236 engine, which was already a four-stroke engine.

After a series of modifications and improvements, in 1985 one of the versions, the MAZ-5551 dump truck, entered mass production. It is the most common in Russia.

An important advantage of the “Belarus” is its agility and maneuverability thanks to the truck’s small wheelbase and two-axle layout.

Therefore, in urban environments it fits perfectly even into small construction sites and turnarounds.

There are no identical “ZUBRs” (MAZ-555102-020) – Fixed assets

A. Erokhin, photo by M. Ralliev

We have already tested the two-axle Minsk dump truck MAZ-5551-020 (No. 6 of 2002, “Bison advanced to the east”). Now the editorial test group is again working with this car, more precisely, with its more modern, if you like, “advanced” version to Euro-2 - MAZ-555102-020. The car's engine, in addition to meeting new environmental standards, has 50 hp more. power. Both dump truck options are almost identical in terms of weight, so we will compare them with each other.

This test had one more important difference from the previous one. Let's start the story with him. So, about the features of operating the MAZ-555102-020 car in winter.

During testing of the car at the Dmitrovsky test site and driving MAZ from and back, the air temperature ranged from –7 to –19°C, which made it possible to fully evaluate the heating system.

Having examined the car allocated for testing, we wisely clarified with the company’s employees that the cooling system of our car was filled with low-freezing coolant, which means the frost was not terrible, after which we set off for Dmitrov. The thermometer outside showed -17°C, the car was taken from the street, so we were eagerly awaiting the engine to warm up and warm air to flow from the heater into the cabin. After 15 minutes of driving, the coolant temperature gauge moved from a dead point, we were unpleasantly surprised that the fan was blowing outside air into the cabin. We didn’t want to freeze, so we stopped, opened the radiator grille and probed the coolant supply hoses to the heater core. Imagine our amazement: they simply froze! As it turned out later, the plant filled the cooling system with water, and the employee preparing the car for the test simply ran into an unscrupulous seller.

In a cold cabin we got to the test site and left the car in a warm room to thaw until the morning. During the drive at a speed of 60 - 70 km/h, the temperature indicator needle did not rise above the beginning of the yellow sector, i.e. In such weather and in such driving conditions, it was impossible to warm up the engine to normal operating temperature.

The first impression of the car was spoiled, but during the drive we more than once recalled with gratitude the editorial management, who equipped the testers with warm winter clothing.

The next day the air temperature rose to -7°C, the car thawed overnight and, having started the engine, we went to test the “curb weight”. Having worked all day, we had no complaints about the temperature comfort in the cabin of our “experimental” one. When the temperature in the engine cooling system is 40°C and above, the cabin heater operates normally.

A few words about the temperature regime of the engine. In the modes of warming up the car (carried out on the highway, do not confuse it with warming up the engine) and maximum speed, after 20 minutes of driving, the coolant temperature indicator arrow is on the border of the green sector, i.e. The engine is warmed up to almost operating temperature. During fuel consumption measurements at constant speeds, the engine coolant temperature decreases as the vehicle speed decreases. At 60 km/h, the temperature gauge needle is in the first third of the yellow sector, and when parked with the engine running, it goes to the very beginning. True, this temperature is sufficient for the cabin heater to operate.

The reason for the unstable temperature regime of the engine, in our opinion, is the quality of the Yaroslavl diesel thermostats, and the absence of blinds or curtains in front of the car radiator does not allow one to compensate for the poor operation of the thermostat “manually”.

After a day of working with an empty car, we drive it into a warm room for the night, since the experimental determination of the freezing point of the “low-freezing” coolant and its ability to destroy the engine block went far beyond the estimated costs.

Let's try to roughly compare the driving properties of two twin MAZs when empty. Rough, because the difference in ambient temperature when testing twins is 22o. For easy comparison, see the table of test results of our MAZ-555102-020 vehicle with a YaMZ-236NE2 engine, 230 hp. We have added a table of test results for the MAZ-5551-020 car with the YaMZ-236M2 engine, 180 hp, taking it from the test of the MAZ-5551-020 car. The power of the YaMZ-236NE2 engine is increased through the use of turbocharging with intermediate air cooling in an aluminum radiator located directly in front of the radiator of the engine cooling system.

A more powerful car has advantages when simulating urban traffic (HC). MAZ-555102-020, despite worse temperature conditions, covered the typical route with 11% higher speed and 9% lower fuel consumption than MAZ-5551-020. The “eco-friendly” MAZ also turned out to be more dynamic: it showed a 5% higher maximum speed and a 5% better acceleration time. In terms of fuel consumption at constant speeds, a car with a conventional engine has a slight advantage.

Loaded vehicle testing

Having loaded the MAZ with ballast (sand mixture) and weighed it, we began testing the fuel and speed properties. The air temperature was kept within 6 - 7 degrees below zero, which made it possible to correctly compare the temperature conditions of the engine of an empty and loaded car. On this day the weather almost let us down. By the middle of the measurements, it began to snow, and we completed them on a snow slope that we had created.

In the modes of warming up the car and driving at maximum speed, the engine finally warmed up to normal operating temperature: the arrow of the coolant temperature indicator took a position in the green sector. As the driving speed decreased, the coolant temperature also gradually dropped, although it was slightly higher than with an empty car.

Naturally, when parked with the engine running, the coolant temperature turned out to be the same as that of an empty car. It is noteworthy that the “warmer” engine had virtually no effect on the temperature comfort of the cabin, except that at maximum speed it was (subjectively) a little warmer.

Comparing the driving properties of loaded vehicles, we note that the advantages of a MAZ with a more powerful engine in acceleration dynamics have become more significant. The difference in maximum speed remained, and in terms of acceleration, the more powerful engine provided an advantage of 20 to 50% over MAZ with the usual Yaroslavl “six”. And fuel consumption at constant speeds is better for a car with a supercharged engine, despite the worst weather conditions. This is how the comparison of twins turned out.

Let's not dwell on a few unpleasant little things. We only note that there were fewer of them on this car than on previous MAZ and MZKT vehicles. And besides, there was no runout of the right (as well as the left) front wheel. It turns out that discless wheels can be screwed on correctly in Minsk...

In conclusion, a few words about the shortcomings that were noted in previous articles. According to them, representatives of the plant told us this. On the conveyor belt of the Minsk Automobile Plant, cars are assembled and then completed only in accordance with the order. An unsprung passenger seat and a creaky driver's seat, mirrors with a strange electric heating that cannot be connected, which does not heat, a cabin that is rigidly attached to the frame, without springs or shock absorbers - all this falls into the category of “but cheap”. This is exactly the configuration that was ordered. Today, a buyer can have a fairly well-equipped car from Minsk, but this is a matter of economic feasibility.

It remains to be noted that compliance with Euro-2 standards is reflected in the price of the car.

General impression

Overall, the car left a pleasant impression. We got acquainted with the vehicle in the most economical version of the dump truck, which is sold at the lowest price. Summing up, we can come to the conclusion that Minsk automakers produce high-quality, reliable equipment.

Body quality leaves much to be desired

When developing this model, the shortcomings present in previous models were taken into account and improved. So, in the MAZ -5551, the designers finally said goodbye to the crowbar-shaped gear shift lever, which was present in all previous models.

And it is no longer necessary, as before, to catch transmissions throughout the entire cabin space. At the same time, the gear shift pattern remained the same.

The drum handbrake on the MAZ-5551 has been replaced by brake chambers with spring energy accumulators. True, the chambers are not equipped with bolts for forced release of the brakes in the event of a lack of air in the system.

But such shortcomings should be treated with understanding, because the cost of the car is significantly lower than similar foreign-made models, stuffed with all sorts of additional components and systems.

Of course, when testing the dump truck, many elements were discovered that required “hands-on,” but there were significantly fewer of them than on any of the vehicles produced at CIS car factories. Thus, the MAZ-5551 dump truck proves that it was not in vain that it inherited the nickname “hard worker”, deserved by its predecessor MAZ-503 back in the 60s.

MAZ-551605: equipment options

A family of new three-axle dump trucks under the designation MAZ-5516 has been produced at the Minsk Automobile Plant (MAZ) since 1994. The distinctive features of the family are simplicity of design and a large margin of safety. These factors are considered decisive when purchasing new or used cars based on the MAZ-5516. Buyers are not afraid of either the low corrosion resistance of the cabins or the unstable quality of the plant’s products.

Development

The first prototype of the modernized car, designated MAZ-551605, was created in April 2002. The YaMZ-238DE2 diesel engine was used as a power unit. Subsequently, the base chassis began to be used for the installation of various superstructures - dump bodies of various configurations, concrete mixers, utility vehicles, etc. Thanks to the powerful main engine, it was possible to ensure high technical characteristics of the MAZ-551605.

The chassis is driven by two rear axles, which provides good cross-country ability and allows the vehicle to be used in difficult road conditions. To meet modern requirements, the brake system uses an anti-lock braking system. Upon request, the chassis is equipped with a comfortable cabin with additional insulation and seat belts for all seats, an autonomous engine heater, and a speed limiting system.

Dump truck

A three-axle dump truck based on the MAZ-551605 is designed for transporting bulk cargo with different fraction sizes. Its body can be unloaded in three directions. There are several variants of the dump truck, differing in the type of cab, type of dump body and the ability to work in conjunction with a trailer.

Currently produced vehicles can be equipped with YaMZ-238DE2 diesel engines or a more powerful YaMZ-7511-10E2 engine. Both engines comply with Euro 3 emissions standards. The engines are equipped with gearboxes either domestically produced (model YaMZ-2381) or imported. The standard load capacity of all dump trucks is 20 tons.

One of the activities of the car is the transportation of agricultural goods. The MAZ-551605-271 with high body sides is designed to perform such work. If necessary, the dump truck can transport any bulk cargo. The body with one-sided unloading has a floor heating system using exhaust gases. The vehicle is equipped with a sprung cabin without a berth.

The power unit consists of a 330-horsepower diesel engine with a YaMZ-238DE turbine and a nine-speed gearbox model 9JS135A. The car has a large power reserve thanks to a tank with a capacity of 350 liters.

Concrete mixer

A mixer for cement and concrete mixtures under the designation ABS-8 DA has been developed and manufactured on the Mazov chassis. The concrete mixer is designed for a wide operating temperature range (from minus 30 degrees to plus 40).

The working drum with a capacity of 8 cubic meters is made of steel sheet and has an adjustable tray for unloading the mixture. The drum is loaded from above, through a special neck. The unloading height is adjusted by tilting the tray and additional chutes and can reach 2 m from the ground level. The average unloading speed is about one cubic meter per minute.

To mix the mixture on the go, a separate 50-horsepower air-cooled D-144 diesel engine is used. Rotation is transmitted to the drum through a gear reducer. The maximum drum rotation speed is up to 14 rpm. The ABS-8 DA concrete mixer on the MAZ-551605 chassis has good speed characteristics - the maximum speed of a loaded machine reaches 50 km/h, and when empty it reaches 75 km/h.

What are the advantages

In conclusion of the review of the MAZ-5551 car, one can note the tenacity and desire of Belarusians to keep up with the times and thereby stay afloat in the competition with branded import brands.

During the crisis in the post-Soviet era, many automobile enterprises closed and ceased to exist, but MAZ survived and developed production to world standards, now competing with the rest.

Of course, when listing the main miscalculations and shortcomings of the MAZ-5551, we must not forget that its price is many times lower than imported ones, which are replete with various technological equipment and capabilities.

Important! For example, the 2013 model MAZ-5551 A2-325 can be purchased for 760,000 rubles. Millions of drivers in the CIS countries perceive the MAZ as a very loyal friend, who will bring them home in both heat and cold, despite its perhaps insufficient comfort and convenience

He is rightfully awarded the popular nickname “hard worker”
