The 500 series is the successor to the 200 series . Prototypes were manufactured from 1958, and series production began in small numbers in 1963. Due to delivery problems in the area of ​​the engines, there were delays, so that it was not until 1965 that production could be completely converted to the new 500 series. The trucks with the 4 × 2 drive formula had a modern sheet steel cab and a maximum payload of seven and a half tons.

In 1970 the 500 series was revised, the new versions were identified by adding the letter A to the original numbers. The main changes to the MAZ-500A compared to the MAZ-500 model were an increase in the payload by 500 kg to eight tons and an extension of the wheelbase by 100 mm. Export versions achieved a payload of nine tons. In addition, the top speed was increased to 85 km / h. The successor, MAZ-5335, completely replaced the MAZ-500A in 1977 and was produced until 1990.

Model versions

The MAZ-500 was the structural basis for a whole series of trucks, which differed in particular in their superstructures. The type designations MAZ-501 , MAZ-502 and MAZ-506 (two-way tipper based on the MAZ-200) had already been assigned in the previous generation around the MAZ-200 .

Series vehicles

  • MAZ-500 - Flatbed truck (basic model)
  • MAZ-500W - The vehicle was built for the Soviet Army with a flatbed made entirely of steel and folding seats for the transport of soldiers. Either equipment or personnel could be transported. Series production took place in small numbers.
  • MAZ-500G - extended wheelbase model. The number of pieces produced remained small.
  • MAZ-500S - see MAZ-512
  • MAZ-500Sch - Chassis without superstructures were delivered ex works under this designation. At other companies, the trucks were then fitted with special structures such as mobile cranes, concrete mixers or tank structures.
  • MAZ-500Ju - see MAZ-513
  • MAZ-503 - dump truck
  • MAZ-504 - tractor unit
  • MAZ-509 - wood transporter with four-wheel drive .
  • MAZ-512 - like MAZ-500, but already equipped with double glazing and similar modifications ex works, especially for use in cold regions
  • MAZ-513 - for tropical areas of application
  • MAZ-514 - three-axis, drive formula (6 × 4)
  • MAZ-515 - Three-axle tractor, drive formula (6 × 4)
  • MAZ-516 - three-axle vehicle, built 1969–1973. Designated as MAZ-516A from 1973 to 1977. With drive formula (6 × 2), the rear axle is designed as a lifting axle .

Prototypes

  • MAZ-505 - As early as 1962, a prototype of an all-wheel drive version was built under the designation MAZ-505, which was designed for military purposes, but never went into series. The vehicle was intended as a successor to the MAZ-502 .
  • MAZ-508 - Also MAZ-508W, four-wheel drive tractor. A prototype was built in 1962. Not manufactured in series.
  • MAZ-510 - construction tipper with halved driver's cab and only one seat for the driver. A separate engine compartment was designed on the passenger side. Not manufactured in series.
  • MAZ-511 - prototype of a two-way tipper, which should be used together with the matching trailer of the type MAZ-847. Built in 1962, there was never any series production. In 1970 a revised prototype MAZ-511A was built, which also remained a one-off.
  • MAZ-520 - three-axle tractor, only a prototype made. An additional axle was attached to the front in order to reduce the axle loads, especially in poor road conditions. The construction turned out to be a failure, as the main load was still on the rear axle.

Technical specifications

The MAZ-500 is a forward control truck with a tilting cab. This was new for trucks from Comecon countries. The vehicles of the 500 series were equipped with V6 diesel engines from the Jaroslawski Motorny Sawod of the JaMZ-236 type. This produced 180 hp (132 kW) as standard with a displacement of 11.15 liters. The consumption was 23 l / 100 km and the top speed was 75 km / h. The fuel tank held 200 liters of diesel. A manual gearbox with five forward gears and one reverse gear transmitted the drive power to the rear axle. The tractor units were equipped with JaMZ-238 V8 diesel engines with direct injection and an output of 240 hp (176 kW).
