C9 series 20 13 excavators have adopted many energy-saving technologies such as dynamic optimization of DOMCS and intelligent matching control, and become the most fuel-efficient excavators in history.

Efficient and lasting: Sany is committed to becoming the master of the core technology and performance of excavators in the world. C9 series 20 13 excavator adopts many technologies such as optimized rotation, which can save energy and improve work efficiency.

Stability and reliability: the essence of Sany brand lies in high reliability. The C9 series 20 13 excavator has made many improvements in strengthening structural parts and reducing failure rate, which significantly improved the reliability of the whole machine and made its working performance more stable.

Precautions for using excavators:

1. Operate in strict accordance with the operating rules and driving essentials, and try to avoid "tooth beating" when shifting gears to reduce the wear of gear pairs.

2, strictly implement the maintenance system, strengthen the maintenance of gear shifting device. When the gear shifting device is not connected properly, it should be adjusted in time to ensure the good performance of the gear shifting device.

3. Pay attention to the repair and maintenance of the self-locking mechanism, timely repair or replace the positioning steel ball, spring and shifting fork shaft that reduce the positioning effect or lose the positioning efficiency, so that the self-locking performance of the self-locking mechanism is in good condition.

4. When assembling the transmission, it should be operated in strict accordance with the operating procedures to ensure that all parts of the transmission are adjusted correctly and appropriately. On a steep downhill road, the driver should operate in strict accordance with the essentials of downhill movement and must not violate the rules.
