MAZ-4370: specifications, owner reviews

MAZ-4307 Zubrenok is the first Belarusianmedium-tonnage truck, with a hatchless layout, a large cargo platform and a significant number of various modifications developed and produced on its basis.

Truck production

MAZ-4370 or Zubrenok is produced by the Belarusiancompany "MAZ". The enterprise traces its history from 1944, when a repair and repair workshop was set up in liberated Minsk. Gradually, the enterprise switched to assembling trucks from machine kits. In 1945, the construction of production workshops of the plant for the production of heavy trucks began. The first MAZ-205 trucks the company assembled in 1947, and two years later the conveyor production of cars was established. An important point in the establishment of the plant was the development and production of trucks in a hood-free layout. In the future, the company, thanks to its own development, not only expanded the range of vehicles, but also significantly increased the volume of production.

Currently, the association MAZ produces more than 80 modifications of trucks for various purposes, and also produces buses, trolleybuses, trailers and semi-trailers.

History of the truck

The appearance of MAZ-4370 is associated with an increase in the late XXcentury demand for medium-tonnage cars, as well as the desire of the company "MAZ" due to a new model to expand the production line of trucks. Such a compact car can be effectively used in urban conditions and on short suburban transport for the transportation of small lots of various cargoes.

In order to accelerate the development andproduction at the enterprise as a prototype chose a truck of a similar class MAN-L-2000, but the carrying capacity of this model was only 2.5 tons. MAZ did not consider the smaller carrying capacity a problem. Due to the developed basic elements of the new truck, frame, suspension, bridges, it not only designed the truck in a rather fast time, but also carried out all the required testing and certification work. This allowed to start production of the MAZ-4370 Zubrenok model in 1999.

Model Construction

Unlike the Russianmedium-tonnage vehicles, the Belarusian novelty has received a traditional for MAZ bonnet layout. This significantly increased the size of the vehicle's on-board platform and, according to this indicator, the MAZ-4370 (among CIS trucks) could only compete with KAMAZ-4308, which was released in 2007.

The next distinctive feature of Zubrenka was a high comfortable cabin designed for 3 people. In order to improve aerodynamics, it was equipped with three spoilers and a fairing.

The basis of the car's construction is stronga ladder-type frame with two spars for the shape of the channel, as well as cross-bars that received a circular tubular and U-shaped cross-section. Due to the dependent type of front and rear suspension on semi-elliptic springs in combination with 17.5-inch wheels, the truck received a low platform layout, which, according to the owners of the MAZ-4370, was very comfortable when carrying out loading and unloading operations.
