717H is an upgraded product of PY165H: the standard configuration of 717H is Hangto 180 gearbox; the fuel tank refueling port of the engine system is heightened, and the fuel sensor is added; Operating force; electrical system improvement; hydraulic system implements a double sealing form of 24° cone and O-ring.

1. Single-handle electro-hydraulic control, load shifting, six first and three rear gears, independent and coordinated hand and foot throttle.

2. It adopts high-efficiency and environmentally friendly Shangchai or Dongkang supercharged engine, which is perfectly combined with Changlin transmission system. It has been tried and tested. The design emphasizes the strength and safety factor of parts and components, and the performance is reliable.

3. Simple and reliable full hydraulic operation, easy to realize all-round adjustment of various actions, such as: blade lifting, tilting, turning, side swinging of the front wheel and soil loosening, there are double-acting anti-drift check valves.

4. The ideal bridge load distribution enables it to maintain excellent stability and adaptability when cutting harder ground. The wide scraper board is connected to the articulated frame, making the machine suitable for a variety of practical operations.

5. Liquid top and liquid four-wheel inner expansion shoe type service brake system, plus neutral start, safe and reliable.

6. Sturdy main frame and reliable transmission system, large front axle and balance box swing angle, improved rear axle input flange connection bolts to solve the loose phenomenon, improved sealing effect on the end face of the rear axle and balance box, and solved leakage Oil failure makes it easier for the machine to complete heavy-duty operations.

7. Wheel drive, exclusive use of imported technology reinforced double-row roller chain: the average breaking strength is 26000kg.

8. A single gear oil pump is used to supply oil to the two control valves through the diverter valve, where the rotary oil circuits merge again, which not only ensures the speed of each action, but also makes the energy consumption of the entire system lower. Hydraulic locks are provided on multiple circuits such as working device lifting, side swing, frame articulation, front wheel side swing, etc. Realize precise control of actions. The imported hydraulic balance valve is used in the lifting cylinder pipeline in the hydraulic system, which has good stability during work.

9. "Autorotation" (anti-slip) differential with automatic locking and releasing device to ensure the best stable steering.

10. In order to adapt to the heavy-duty operation of the whole machine, and strictly ensure the strength of the main components such as the scraper, the scraper is 30% thicker than the general grader. Specially designed edge blades on both sides of the blade can better perform operations such as trench digging and road surface peeling.
