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 ?30.1?? truck cab has height of 3170 mm) enables easy installation of crane and other equipment, while wide windshield provides excellent visibility.
