The Sand Dredger is the flagship product of Qingzhou Yongsheng Sand Dredging Machinery Co., Ltd. Our sand dredgers boast advantages in depth, strength, and quality. After years of dedicated research and development, we have developed a high-tech system, utilizing full-hydraulic technology with large processing capacity and high efficiency. We have extensive experience in the manufacturing of sand dredgers and also have methods for their operation and maintenance. Below, we will introduce these to you.

1. When dredging vessels move forward or backward based on geographical conditions, their movements must be agile. Any large rocks, mud, etc., must be cleared.
2. Ensure that chain bolts, pins, and fasteners at all fixed points of the drive system are always securely tightened.
3. When shutting down a sand dredger, the front diesel engine should be turned off first, followed by the rear diesel engine.

4. In the event of strong winds (above level 5), the machine should be temporarily shut down to prevent malfunctions. The machine should be powered off during maintenance or part replacement to avoid personal injury accidents.

5. Regularly inspect all screws during operation and frequently lubricate and maintain them, especially the hopper screws, chain pins, the four corners of the water wheel, and the bolts connecting to the 500-speed reducer disk. For the underwater four corners wheel, etc., it's necessary to frequently apply grease and lubricant. During flood season or when not in use, tie the sand dredger securely to prevent it from being swept away or incurring unnecessary losses.
