Fuel consumption standards for MAZ 551605 • Dump truck MAZ-5516

MAZ 551605 is a series of three-axle dump trucks with a 6 by 4 wheel arrangement. The model is based on the popular MAZ 5516 family. The prototype premiered in the spring of 2002. An improved YaMZ-238DE2 unit appeared in the engine compartment of the car. The MAZ 551605 chassis was later used for the installation of various equipment and superstructures (concrete mixers, dump platforms, municipal vehicles and others).

MAZ 551605 “inherited” the main advantages of the MAZ 5516 model. The chassis with 2 rear axles provided excellent maneuverability and made it possible to operate the equipment in difficult conditions. In this regard, the scope of use of the machine was quite wide. The car was in greatest demand among construction organizations, where it was used to transport materials along various roads. In agriculture, machinery was used to transport compost, crops and soil. The machine was also used in forestry as a log carrier. According to its characteristics, MAZ 551605 successfully competed with foreign cars of a similar segment.

Review of technical characteristics of MAZ 551605 and design features

Dump trucks and quarry trucks are a truck with a self-unloading device that can be equipped on the body, trailer or semi-trailer (most often of the hopper type). The movement of the body to unload cargo is carried out using powerful hydraulics, mechanics, and also with the help of augers. This technique is mainly used for transporting various materials, both loose and bulk, which can be suitable for unloading by tipping the body.

• in the direction of cargo unloading (backward or sideways);
• by type of container for transportation (platform, sliding hopper or platform, simple hopper);
• by the method of unloading cargo (by tilting the body or using additional devices, augers);

It is worth noting that dump trucks often have a much smaller load capacity than a conventional truck, but dump trucks remain quite profitable to use due to their unloading speed. The lower lifting capacity is due to the fact that the hydraulic drive for raising the body is designed for a certain performance.

Car history

In the early 90s of the 20th century, the Minsk Automobile Plant had already gained sufficient popularity. In addition, developments continued to appear, and the next one was the MAZ-5516. This model has become the pride of the manufacturer as one of the most popular dump trucks.

After inspections, tests and other tests, in 1994 the first MAZ-5516 was released, ready for use. Thanks to its huge load capacity of 20 tons, the truck could be used in many areas:

• Urban development. The machine was used for transporting asphalt and other materials, removing waste and garbage;
• Agriculture. Here, transport was used to transport compost, soil, liquid, crops and fertilizers;
• Construction. The model was used for transporting liquid solutions, dry mixtures, stones and bricks in stacks and in bulk.

The main emphasis was on the third point - construction. Since the vehicle was adapted to transport bulk cargo, this area, like no other, involved the MAZ-5516. And taking into account the number of constructions after the collapse of the USSR, there was a lot of work for the dump truck.

Device

MAZ 551605 was developed to transport large volumes of cargo, which is why it is based on a high-strength frame. At the rear of the frame there are 2 drive axles connected by a cardan shaft. The gearboxes are configured in such a way that the number of revolutions of the middle axle is greater than that of the last one. Since it is the middle axle that is the busiest, this solution provides optimal traction. The model uses a standard chassis with spring front suspension and spring-balance rear suspension.

The model of transmission installed on the MAZ 551605 is largely determined by the type of unit. Most of the modifications are equipped with an 8-speed manual transmission YaMZ-238M. The transmission includes a clutch from the Yaroslavl Motor Plant (YaMZ-184-15). A single-disk dry friction element is responsible for transmitting force from the unit to the gearbox.

The service braking system operates on all wheels. Drum brakes are used here. All versions have ABS. The parking and spare brake systems affect the components of the middle and rear axle. The parking system performs certain functions as a spare and is used in case of failure of the working system. The auxiliary braking system is used to provide slight deceleration during long descents.

In the design of MAZ 551605 one can immediately recognize the typical features of the Minsk Automobile Plant products. The rectangular cab with smooth corners and a massive bumper installed for protection make the car very practical. There are 2 cabin options for the car:

• standard;
• extended with the possibility of installing a sleeping place.

Despite the fact that the MAZ 551605 appeared in the early 2000s, the level of comfort in the cabin remained minimal. The interior is equipped with a sprung driver's seat with an adjustable function and an adjustable steering column. Pneumatic shock absorbers of the chair make movement more comfortable. The seat also has horizontal and vertical adjustment elements and backrest adjustment. Armrests and headrest are optionally available. A powerful heater provides the desired temperature during the cold season. The tunnel has a storage compartment that can be used as a table. There is no air conditioning in the MAZ 551605, although taking into account the specific operation of the car it would not be superfluous. To reduce vibration, the cabin is suspended by springs at 4 points. The doors are made of sheet steel and equipped with rotary locks. The steering is represented by a steering mechanism with a distributor.

Technical component of the dump truck

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.

MAZ-5551 owner reviews

• Anton, Petropavlovsk. I will briefly describe the truck in three words - comfortable, economical and maneuverable. I only worked on this machine for five years. I got a job at a state enterprise, which I got so used to that I began to treat it as if it were my own, including the MAZ-5551 truck. This model is a good workhorse, unpretentious in long-term use. In frosty weather or hot weather, this truck never made you worry about reliability, breakdowns, etc. The vehicle is equipped with a 180-horsepower engine. The brakes are quite powerful and stop effectively. The car's maintainability is at a high level, but in the event of a fuel leak or other serious problems, you will have to spend a tidy sum. It is advisable to seal air connections not only with sealant, but also with rubber rings. The tubes must be reinforced with rubber hoses to prevent anything from bursting. The car consumes 20-25 liters in the urban cycle.
• Nikolay, Orenburg. MAZ-5551 is a warm and economical car with high maneuverability. The machine does not cause any reliability problems. Able to work properly in extreme cold. On duty, I often worked in Siberia, where the frosts are very severe. We had to transport cargo from one end of the city to the other, as well as transport it between cities. Of course, there were breakdowns, but I always had a set of the necessary tools. But if there was no spare wheel left, I simply called for help and sat warming myself in the cabin - the heater in the MAZ is quite powerful and has never failed. The fuel tank lasts for several hours of driving. The car is equipped with air brakes, so you need to constantly pump up the air. I will also note the high cross-country ability. On rough terrain, my MAZ-5551 is simply a beast, capable of driving along forest paths. I have a 2000 model with a manual 5-speed transmission. Average fuel consumption is 20 liters per 100 km.
• Alexey, Yaroslavl. Among the advantages of this truck, I would like to note well-thought-out ergonomics and effective brakes, a powerful heater and a high-torque engine. But the clutch is very tight, the cab is not sprung, and the truck’s maneuverability in the winter leaves much to be desired. At least with stock wheels. I've been working on the MAZ-5551 for about six months, and I'm not at all impressed with the car. There are many more disadvantages than advantages. Constant breakdowns plague me. Maybe the whole point is that before me this truck was used carelessly, it was regularly overloaded and did not spare the car. The car has a terrible lift. By the way, I have a 10-ton dump truck with a lift cylinder mounted in the middle of the body - who ever thought of that? For example, I take six tons of screenings and deliver it to two different places - 3 tons for each place. I arrive at the first point and unload the first half (3 tons), at this moment I release the body, which simply falls onto the frame. As a result, the frame is heavily overloaded due to the fact that the lift is located in the center. If you deliver it to four different places, you can damage the frame, after which the truck will be inoperable. In general, six months passed, during which time I changed the lift valve three times. Another time I had to install a new lift pump. An unsprung cabin is a serious drawback; because of this, it shakes violently, there are terrible noises and vibrations, and the clutch fails. The on-board electronics were replaced once. The compressor is very weak and lacks power. A car with a 185 horsepower engine that consumes 20-25 liters per 100 km. On a slippery road, slipping is possible, for example in snow or on an icy road, even when loaded. In this case, blocking does not help. But in the summer there is no slipping, the car rushes through the mud like a tank.
• Denis, Bryansk. I drove a MAZ-5551 70 thousand kilometers. This time was enough to convince us of the simple and unpretentious design of the truck. I have a modification of a dump truck, I liked the original, strict design of the cabin. For this class, the truck is very economical even when loaded. I have been working on this dump truck since 2008. I will note the advantages of the cabin - comfortable, roomy, with three full seats. Under the hood is a YaMZ-236 engine with a turbine, power 180 horsepower. The transmission is five-speed manual, and the brakes are equipped with a pneumatic system. The fuel tank holds 200 liters of fuel, which provides a large range, so there is no need to visit gas stations frequently. I still work at MAZ, the car does not cause serious problems. Consumes 20-25 liters depending on driving style and road quality. In general, Belarusian designers have created a very reliable car.
• Dmitry, Irkutsk. An excellent engine and powerful brakes, an energy-intensive suspension and excellent visibility - and these are not all the advantages of the MAZ-5551 truck. Repairing it is not difficult, it’s a matter of habit, and you need to understand the device. The car is generally good, it has never let me down on a long journey. Of course, there are minor breakdowns, you can’t escape them. After all, the car is essentially domestic and loves repairs. Most of the components are of second-rate quality, so to speak, and they are in short supply for a long time. Therefore, you have to periodically replace some parts. But all the components are available - either new or used.
• Rinat, Udmurtia. Maneuverable and very powerful truck, I'm as happy with it as an elephant. I’ve been working on it for ten years now, without any interruptions. Surely the MAZ-5551 will serve me for many more years. The first time I got a job in a cargo company, it was still in Kaliningrad. Then they provided me with a MAZ-5551, this was my first experience with this truck. Now I drive an updated car, but then it was just an indescribable feeling. A wonderful engine - with a pleasant growling sound from six cylinders. Very durable design, and without any electronics. A machine with a carrying capacity of 8 tons, although I loaded 11 tons. Despite this, the car pulled confidently and did not “stumble.” Of course, it was not without its shortcomings. The car is equipped with a single rear axle, so if it falls into the ground, you will need a cable. And as a tug you will need some kind of all-wheel drive special vehicle, because the heavy MAZ-5551 cannot be pulled out so easily. I say this to mean that a loaded car is not capable of proving itself off-road. As a last resort, you need to install wider-profile and toothy tires. In the urban cycle, the car consumes 22 liters per 100 km. I am currently driving a 2010 model year truck. The updated MAZ has slightly better cross-country ability.
• Alexander, Stavropol region. Of course, this is not a KAMAZ, but it is a very good and versatile truck for any need. A kind of affordable alternative to KAMAZ. The car is quite reliable, the cabin is very spacious. I liked the maneuverability due to the powerful engine. Cross-country ability is significantly worse than that of KAMAZ. Despite this, the MAZ-5551 instills a feeling of reliability. An excellent car for its class. Thanks to its reliability, this model is a good assistant in hard and painstaking work. In other words, this was once my breadwinner, so to speak. Or the main source of income. Due to its compact dimensions, the MAZ-5551 is endowed with good maneuverability and cross-country ability is sufficient for driving along country country roads. As for carrying capacity, in this discipline the MAZ-5551 is between Kamaz and Zil. The machine is suitable for delivering construction materials. At the end of the working day, the back practically does not get tired, since the seat has the correct shape, which follows the profile of the back. Fuel consumption in the city is 24 liters, and off-road the car consumed 26 liters.
• Igor, Novosibirsk. This truck has excellent endurance, but very mediocre cross-country ability. Like all MAZs, the car is reliable, despite the cheap components. Due to its strong body and running characteristics, the vehicle has proven itself in many heavy industries, including the forestry and chemical industries, as well as the construction industry. I worked at MAZ in many areas, and everywhere I tested the strength of the 5551. The most serious disadvantages include off-road problems. Even on wet grass the car begins to slip, not to mention the icy or snowy road. But the car is ideal for its purposes. MAZ-5551 consumes 24 liters per 100 km on average.
• Boris, Minsk. I work on MAZ-5551 and feel proud of the Belarusian automobile industry. Our engineers have created a machine that, in most respects, is not inferior to its Russian counterparts, and at the same time costs significantly less. In addition, our truck has a higher quality of workmanship. And yet, even our craftsmen have something to work on. After all, our problems also have quality problems. For example, I came across a copy assembled from clumsy bolts. The Yaroslavl-made engine does not shine with durability. I have been working on this truck for almost 10 years, transporting metal structures, garbage, crushed stone and other bulk materials. The steering mechanism often malfunctions, the fuel pump often leaks, and the pipes (they connect to the receiver) burst repeatedly. In general, there is a lot to complain about, and MAZ has many shortcomings. But in any case, MAZ is more reliable than Kamaz. Our truck is more repairable. Under the hood is a 180-horsepower engine with a manual transmission that consumes no more than 25 liters per 100 km.

Advantages and disadvantages

As noted above, the MAZ-5516 has quite a few pros and cons. Taking into account the first versions, it is worth paying attention to the poor design of the cabin and the lack of conditions for comfortable work in it.

The mechanical part, engine, transmission and other mechanisms are manufactured and assembled with high quality. Modern Minsk dump trucks are improved in both respects and make the owner happy.

As additional qualities of the machine, we note the following:

• Economical, low repair costs. Almost all analogues are much more expensive to repair, and spare parts for them are more difficult to obtain;
• Easy to maintain. No special service is required for repairs. The systems are simple in design and easy to repair;
• To increase the productivity of the truck, it is possible to attach a trailer;
• Compared to analogues, the car is much cheaper, and therefore more affordable. A new 20-ton truck is sold from an official dealer at a price of approximately 2 million rubles. A used car in slightly worse condition, but still ready for exploits, costs about 400 thousand rubles. Both options will carry out transportation conscientiously, but, obviously, there will be fewer problems with the new car;
• Proven and proven suspension system. Despite the heavy loads, now even with mileage the car will be in good condition;
• A powerful power unit that allows you to easily move across various terrains and transport cargo at the same time.

We can say that all the negative reviews are taken over by the first versions of the MAZ-5516. And the positive qualities in the latest copies indicate the manufacturer’s desire to develop and make their equipment better.

The high rating is given not only by the fact that the designers corrected many defects.

At any time, the dump truck performed its assigned tasks at the best level, and, if necessary, even exceeded its capabilities stated in the passport.

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.
