The dredger is the flagship product of Qingzhou Yongsheng Environmental Protection Dredging Equipment Co., Ltd. Our dredgers boast advantages in depth, strength, and quality. After years of diligent research and development, we have developed a high-tech system featuring full-hydraulic operation, with large processing capacity and high efficiency. We have extensive experience in manufacturing dredgers and also provide methods for their use and maintenance. Here's an introduction:

1. When sand dredgers are advancing or reversing based on the geographical conditions, their movements should be agile. Any large rocks or mud must be cleared.
2. Ensure that chain bolts, pins, and all fixed points of the drive system are securely tightened at all times.
3. When shutting down a sand dredging ship, the forward diesel engine should be turned off first, followed by the aft diesel engine.
4. In the event of strong winds (above 5 levels), the machine should be temporarily shut down to prevent malfunctions. The machine should also be powered off during maintenance or part replacement to avoid personal injury accidents.
5. Regularly inspect all screws during use and frequently lubricate and maintain them, especially the hopper screws, chain pins, the four corner wheels on the water, and the bolts connecting to the 500 reducer disk, ensuring they are securely fastened and in good condition.
