Efforts are underway at “AutoKrAZ” to develop a promising lineup of cabover vehicles. Another novelty of the Kremenchug Automobile Plant is a new KrAZ  Н27.3ЕХ (8х8) chassis truck used to carry special equipment such as cranes, equipment for oil and gas and forest industries.

27-ton KrAZ Н27.3ЕХ chassis truck is provided with the YaMZ-7511.10 V-engine meeting Euro 3 rated at 400 hp, the YaMZ-184 single disk clutch and the YaMZ-2391 transmission. This power plant and powertrain allow for improving traction performance of the vehicle. Minimum turning radius between walls is 14 m.

The novelty features engine behind cab layout and length from back  of cab to end of chassis of 8080 mm. First and second axles are steerable, all the axles are driving. Integral power steering allows reducing force applied to steering wheel to 10 kgf, it helps reduce driver fatigue. All-wheel drive provides for use of this vehicle on rugged terrains.

The KrAZ Н27.3ЕХ chassis truck has a frame made of hot rolled channel bars  connected with cross members, channels bars are made of low alloy steel. The powertrain includes transfer case with interaxle differential that transmits torque to rear bogie and front axles, steerable first and second axles, rear tandem axle with interaxle differential on intermediate axle, positive locking interwheel differentials of all the axles. Suspension of the first and second steerable axles consists of longitudinal semielliptic springs and telescopic shock absorbers, equalizing beam suspension consists of two semielliptic springs.

Low mounted ergonomic Hubei RDGD cab, 2800 mm (for comparison  the KrAZ Н30.1ЕХ truck cab has height of 3170 mm) enables easy installation of crane and other equipment, while wide windshield provides excellent visibility.

The novelty will be unveiled at the International Exhibition of Construction Engineering and Technologies  СТТ-2014 held June in Moscow.
