General information/history of KrAZ 255

The KrAZ-255 is a popular Soviet all-terrain truck with a six-by-six wheel arrangement, nicknamed “bast shoe”, “lunokhod” and “lapotnik”. Its production started in 1967 at the Kremenchug Automobile Plant. The model was discontinued in 1993.

The basis for the creation of the KrAZ-255 was the KrAZ-214. The car got its general layout from him.

Among the key differences are wide-profile tires equipped with a pressure regulation system, and a more economical and powerful YaMZ-238 engine. The need to modernize the KrAZ-214 arose in the mid-60s. The truck, quite acceptable for its time, began to lose to its competitors in terms of technical parameters.

As a result, a new all-wheel drive heavy truck appeared. Externally, the KrAZ-255 was practically no different from its predecessor.

In 1969, the model acquired an updated front lighting design. The turn signals and headlights were installed in rectangular metal boxes. Previously, the headlights were located separately from the turn signals.

The KrAZ-255 was a truly iconic vehicle for the entire Soviet truck market. The model became a symbol of the Kremenchug Automobile Plant and one of the most widespread modifications of equipment in the 1970-1980s.

The tractor was used to transport personnel and cargo off-road and on-road and was a leader in the rating of reliability and technical aesthetics. At a time when national economic facilities and the army needed a three-axle truck with high cross-country ability, capable of traveling on type I and II roads, the creation of the KrAZ-255 was necessary. The increased cross-country ability of the model was ensured by a single-wheel tire, permanent all-wheel drive, a tire compression adjustment function and small overhangs.

The equipment went through many tests and worked in extreme conditions, but very rarely failed. The number of KrAZ-255 models produced was 25% of the total number produced at the plant. Low cost, excellent maneuverability, maintainability and unpretentiousness ensured the car's high popularity in African and Asian countries. The Kremenchug plant exported up to 85% of trucks.

Device

Externally, the KrAZ-255 looks rather unpretentious. The wooden cabin, which seats three, is lined with steel and is located behind the engine. The instrument panel is simplified as much as possible and has a small number of primitive indicators and mechanisms. In 1969, the appearance of the truck changed somewhat. The front part received a new lighting system mounted in a single rectangular body. Also in the cabin were windshield washers, an updated seat with a spring suspension, a set of additional settings and a hydraulic shock absorber, a panoramic glass heater, a removable sleeping bed and a heating system. The driver's seat became sprung and was adjusted for height and weight.

The body of the KrAZ-255 is made in the form of a metal cargo platform with a lattice side that opens at the rear, arches, side folding seats and an awning.

The convenience of controlling the tractor is added by the gearbox levers, axle differential, winch mechanism and hand brake installed in the cab.

During the design process, special attention was paid to ease of operation and ease of control of the vehicle. Initially, the tractor was equipped with a pneumatic power steering, which was soon replaced by hydraulics. The steering gear is characterized by a gear ratio of 23.6.

The advantages of the KrAZ-255 lie not only in its comfortable interior. The six-by-six road formula provides for the presence of three drive axles at once, which makes the model super-passable.

The truck received an advanced YaMZ-236N transmission for that period with a 2-disc dry friction clutch. The 2-speed manual transfer case was equipped with a center differential for the rear and middle axles.

The KrAZ-255 cardan transmission includes 5 open-type cardan shafts and an intermediate post. Each bridge is designed for specific nodes and is a master.

The updated front suspension is equipped with a pair of telescopic 2-way hydraulic shock absorbers and axial semi-elliptic springs. The rear suspension is located on 6 reactive metal rods and 2 axial semi-elliptic springs.

The KrAZ-255 is equipped with drum brakes with a 2-circuit pneumatic transmission. Unclamping occurs through a cam device. The parking brake is a drum-transmission device with a mechanical transmission.

The unusually long life of the car is due to the high quality of parts and successful design. The production of KrAZ-255 was suspended for personal reasons at the Kremenchug plant in 1993. At the same time, there were quite a lot of orders for the model at that time.

Price of new and used KrAZ 255

It will not be possible to buy a new KrAZ-255 vehicle, since the model has been discontinued. Options from 1990-1993 will cost 600-700 thousand rubles. Renting a KrAZ-255 is quite difficult. At the same time, the rental cost is 1000-1100 rubles per hour.
