Shanghai We are the first in China to have mastered the KOMATSU technology in manufacturing gears with crowned teeth and tip relief. This helps ensure the final drive of our bulldozer is with heavy load capacity, stable drive and long life.

1. The bulldozer comes with optimized outer design.
2. The new type engine from Shanghai Diesel Engine provides large power margin, high torque output, low fuel consumption and reliable control.
3. Hydraulically powered, the machine offers automatic speed regulation, and gear shifting without stopping.
4. The three-element, single-stage and single-phase torque converter features high efficiency and large capacity.
5. The updated hexahedral cab provides outstanding visibility and good tightness.
6. The triangle spline and the gear with crowned teeth and tip relief are used in the final drive, which contribute to the uniform loads on the transmission components, high stability and extended lifetime of the parts.
7. The bulldozer uses new blade which is durable and capacious.
8. Alarm monitoring system is efficient and reliable.
9. Controls are piloted to maximize ease of use for the operator.
10. Various options are available including U blade for mining, large size water tank for operating in desert, cold weather starting aid for operating in the areas with cold weather, ROPS and FOPS cab with air conditioning or with heating system, LGP track frame for operating in swamp terrain, and more.
