As you know, every war ends sooner or later the world. It is not surprising that the Soviet Union won the time of Nazi Germany, after the end of hostilities began to actively rebuild the destroyed state property. Needless to say that any construction work that requires special equipment. In this regard, a special burden was placed on the Minsk automobile plant, which began production of its own truck. About it and we will discuss in this article, and find out in particular how much weight the frame of the MAZ-509.
Initially, 500 series, of which this car is a progressive and turned over to some extent the minds of Soviet engineers and drivers. And all because the developers of the machine proposed to place the motor directly under the cockpit, not in front of her, as it was previously. Also the cabin has received property of a rollover, which allowed easy access to the main nodes of the MAZ-509. In addition, the lack of the bonnet gave the possibility to increase the length of the truck and increase its capacity. Initially this engineering proposal has been met with hostility, however, international experience has shown that these machines are quite viable, and therefore the technical Commission approved the project.
April 6, 1966 Assembly of the first instance MAZ-509П. This truck was made, that is, the piece had some drawbacks, which are quite quickly corrected directly on the ready-made machines.

Technical parameters of this truck had significant differences from those cars that the Minsk factory produced before. Let's start with the fact that the bridges MAZ-509 were all-wheel drive, and this unit was the only one who went to the series.
Phased technical upgrade of the machine has led to the fact that she was able to go faster. The speed of the truck increased from 60 km/h to 65 km/h, made possible by the change gear ratios of the gearbox. MAZ-509 differed from its progenitor and that had a wider wheelbase, the value of which has increased immediately by 10 inches. Also, there are double disc clutch, and increased load capacity (half a ton). The front axle was also changed: it was established conventional planetary gearboxes instead.
The MAZ-509, the frame of which was distinguished by increased rigidity have been developed and used for the carriage of timber as a special road and panel lines. However, he had the opportunity to go into the logging. To ensure optimal conditions for loading/unloading the car since 1969, beginning to be supplied with a hoist having a rotating horseman and a folding stand. The Mountie was able to withstand a load equal to 5500 kgs. The truck is equipped with trailer-dissolution: TMZ-803М or GBK-9383. These mechanisms had two axes and the device samokatskaya, which allows to fold the truck and trailer to ship it on a tow truck. In those moments when the truck has not been used and was loaded on the truck, MAZ has become biaxial. When there is a need to transport wood, the trailer was displayed and the truck transformed into a four-axle, both axle he was leading.
The MAZ-509 had six-cylinder power unit (engine) cylinders are in the shape of the letter V. In the presence of a water cooling system. The power of the motor was such that the truck could be the truck tractor. Have differences and transmission, which allowed to be the car all-wheel drive.
The MAZ-509, specifications of which are given below has been sufficiently strong timber with a high degree of permeability, which was explained by the necessity of its use is far from human populated areas with difficult terrain and weather conditions.
The Parameters of the truck is as follows:
It is Worth noting that MAZ-509 was repeatedly subjected to the experiments. They were related to the fact that on its basis was developed the other four-wheel drive cars. One of these wasdump truck MAZ-509Б, completely unified with 509-d model and army truck tilt type. However, none of the above options somehow not entered the mass production, even despite the fact that fully meet all technical standards and requirements of the time.
In 1978, rolled off the Assembly line of MAZ-509А, which differed from its predecessors only external features, but not the internal content. The production of this truck was completed almost simultaneously with the collapse of the Soviet Union, but some cars and still quite actively exploited.
