Boat type frame of high carrying capacity: The boat type frame structure and the cast and welded rear axle feature high carrying capacity, high resistance against impact and bending moment, less welding, high strength, high reliability, and safer internal parts.

 New track roller frame and final drive of higher durability: The planetary final drive features small volume, high carrying capacity, and high plane installation strength. The integral track roller frame features high durability, high resistance against mud accumulation and traveling wear, and long life.

 Double drive shock-absorbing structure of higher durability: The newly added shock absorber assembly absorbs the impact load to protect the drive system. The drive assembly installation adopts semi-suspension elastic shock absorber to isolate the transmission of impact and double the comprehensive life.

Wearing parts of higher wear resistance: The wheel train are made of high-strength wear-resistant materials, with the overall quenched wearing layer thickness 2 times of that of domestic competing products and the cutting edges and end bits thicker by >20% than those of domestic competing products.
