Main Features
1. 320 hp Bulldozer (320 hp dozer) has high engine power, large output torque, low oil-consumption, reliable.
2. Hydraulic transmission, automatic speed regulation, gear shifting without stopping the machine.
3. Bulldozing working equipment can lift and tilt, adopting hydraulically servo controlling, which makes it easier to control. High-strength and corrosion-resistant blade possess high loading capacity and high wear-resistance.
4. 320 hp Bulldozer the new-style steering hydraulic-operated control valve makes it more convenient to control, reduces the labor intensity, and improves efficiency.
5. The novel hexagon cabin, a broader vision, better ventilation, better sealing effect.
6. The new-style three-stage alarm device is mechanically integrated, electronic monitoring instrument shows three-stage alarm.
7. Diverse optional device: U blade, straight angle blade, angle blade, cabin with air conditioner, driving shack, ROPS-FOPS device, three-gear ripper, single-gear ripper, heater, warm air aid, ether starting aid etc.
8. Many variants such as pipelayer.
9. Similar to CAT D8 bulldozer.
