Performance of the PD320Y-1 Crawler Bulldozer

1. The appearance of the vehicle is based on optimization design.
2. Higher engine power reserves efficiency,bigger torque output,lower fuel consumption,while better reliability.
3. Hydraulically controlled drive,automatically speed regulating and non-stop gear shifting.
4. 3-element,single stage,single pgase torque converter for higher efficiency and bigger capacity.
5. The novel hexahedral cab offers excellent visibility,the powerful ventilation and unparalleled dust-free.
6. The final drive uses trangle Spline and trip relief,crowned gear drive for enhanced balance and the stability during power transmission,and added lift.
7. New blade is more durable and capacious.
8. Alarming&monitoring system is efficient and reliable.
9. Implement controls are piloted to minimize operating effort.
