It is worth noting that the history of the Minsk Automobile Plant is a collection of great successes and victories. At the Brussels specialized exhibition, the 50 series truck from Minsk manufacturers was awarded the highest category. Subsequently, it is planned to increase production without loss of quality indicators. The plant at one time was awarded the Orders of Lenin and the Revolution, as well as other honorary awards.

This vehicle is the pride of the plant, produced under the index 5516. The first modification of this truck rolled off the assembly line in 1994. Then the car has undergone a number of upgrades and improvements. Drivers and users note the ease of operation and unpretentiousness of the dump truck.

This type of truck is equipped with a bucket body with a load capacity of 20 tons. Based on this basis, the technique is focused on the transportation of bulk cargo and building materials. The indicators of the technical plan of the machine were optimally suited for various climatic regions.

Description

Maz dump truck (20 tons), the photo of which is given above, was produced with two types of cabs. The extended version provides for the presence of a sleeping bag. The updated large-tonnage vehicles were produced on the basis of agricultural dump trucks with an increased body height and the possibility of two-way unloading.

Vehicle in questionproduced for two decades. During this time, the series has received a number of improvements and positive changes, while the evolution of the multi-ton truck continues to this day. The first modifications were equipped with diesel power units. Versions were available under the index 240 and 330. More modern models received motors with a capacity of 330 horsepower.

The environmental friendliness of the engine of this truck corresponds to the Euro-3 category. As experimental versions, there are trucks with a 400-horsepower power unit from a German manufacturer. They are more expensive, they are in demand not only here, but also abroad.

Truck Features

Super dump truck MAZ (20 tons), equipped with a classic YaMZ engine, includes a mechanical transmission unit. On modern modifications, a German manual gearbox with nine modes is used. Some versions of the dump truck are supplied with a reinforced frame (spar-in-spar variation). As users and experts note, in this case, the price of the vehicle increases, which leads to a slight drop in demand.

The standard formula for the cars in question is 64. The maximum truck can accelerate to 80 km / h. At the same time, fuel consumption is about 30 liters per "hundred". Fuel tanks hold 350L.

User feedback on operation

As noted by the reviews, the MAZ dump truck (20 tons) shows itself perfectly in business, even with a ten-year mileage. This speaks of the high build quality and thoughtful design of the equipment. In addition, experts confirm that the machine in question has a high rate of performance and reliability.

Despite all the transformations of the car, the ergonomics and comfort of the cabin are not much improvedgot. The price of a vehicle largely depends on the condition and replacement of components and main units. Users note that MAZ dump trucks (20 tons) are mainly workhorses focused on operation in the construction and economic sectors. The constant improvement of the truck has ensured its demand for many years.

Flaws

The following are the main disadvantages that this dump truck has:

• Excessive suspension stiffness, poor ergonomics and cab comfort are noted.
• The monotonous and unpresentable coloring is not very impressive.
• Not always reliable engine operation.

Despite all these shortcomings, this truck was highly rated. The machine was created exclusively for working purposes, proved its performance faithfully. A load capacity of 20 tons is not the limit of cargo transportation. At low speeds and flat areas, the vehicle is capable of carrying up to 30 tons.

Modernization

Since the truck in question is not highly maneuverable with a gearbox ratio of 7, 24, the designers have provided some innovative implementations in subsequent releases. Among them:

• An improvement to the shift lever that left much to be desired due to stiffness, uneven movement and sluggishness when shifting into gears.
• Designers made a number of manipulations to improve the comfort and space of workerscabins.
• Now the driver has a better view thanks to the high seating position.
• The engine has been heated to make it easy to start at sub-zero temperatures.
• Enhanced noise and vibration isolation.
• The seat was equipped with adjustment in several positions.
• Introduced pneumatic shock absorbers placed under the seat, which reduce operator fatigue during long work and travel over long distances.

The truck in question is equipped with an engine from the Yaroslavl plant (type - YaMZD-238D). Its power is 243 horsepower with a torque of 1225 Nm. On modern modifications, power units are practiced, the power of which reaches 400 horsepower. Their working life is more durable, but the devices are more difficult to maintain and repair compared to domestic counterparts.
