The design of the dump truck was maximally adapted for work in quarries and road construction. Rear unloading The bodywork was carried out using a hydraulic mechanism, which was highly reliable. The YaMZ-238 engine provided the necessary power, and a simple electrical circuit made it possible to carry out repairs in the field.
During this period, the plant actively introduced improvements to the design, increasing driver comfort and safety. The cabin, although it remained spartan, received improved sound insulation and a heating system. KrAZ model range was replenished with modifications with an extended wheelbase and special bodies.
- 💧 KrAZ-256B - a basic model with a bucket body, which became the most popular on construction sites in the USSR.
- 🌡️ KrAZ-256L — a modification designed for transporting timber, equipped with bunks and a reinforced frame.
- 🏗️ KrAZ-256S — a construction dump truck with increased load capacity and reinforced suspension.
It is important to note that it was during these years that a steady demand for these machines in agriculture was formed. Farmers valued them for their ability to handle heavy trailers and attachments. Engine life before the overhaul, it often exceeded the indicators declared by the factory with proper care.
When purchasing a KrAZ-256 for restoration, pay attention to the condition of the frame side members - they are the ones that most often suffer from corrosion and cracks due to long-term operation with overload.
Army all-terrain vehicles: KrAZ-260 series and modifications
With the start of release KrAZ-260 The plant reached a new level by creating an all-terrain vehicle capable of going where other equipment got stuck. This model became the main heavy truck of the Soviet army and was used for transporting goods, towing artillery and installing special equipment. The 6x6 wheel arrangement provided phenomenal cross-country ability.
The design of the car included a tire inflation system, which made it possible to change the tire pressure on the go to improve traction. Transfer case with differential locks, it transmitted torque to all wheels, making the car almost invincible off-road. The cabin was protected from dust and moisture, which made it possible to operate the truck in deserts and taiga.
⚠️ Attention: Operating the KrAZ-260 on hard roads with the front axle constantly engaged leads to accelerated wear of the tires and transmission; use all-wheel drive only on soft ground.
The KrAZ model range was actively expanded over the years during this period due to specialized versions. Truck tractors for transporting tanks and missile launchers appeared. Engine YaMZ-238L had an increased service life and ran on diesel fuel of any quality.
Drivers noted the high seating position and excellent visibility, which was rare for trucks of that time. However, the weight of the car and the lack of power steering in early versions required significant physical strength from the driver. Was later introduced hydraulic booster, which greatly simplified management.
