This 500 m³ Split Hopper Barge is designed and built by Qingzhou Yongli Mining and Dredging Machinery Co., Ltd. When used in inland waterways, ports, and coastal engineering projects, it loads silt, sand, gravel and other materials on site, transports them safely to designated areas, and discharges cargo quickly through its hydraulic split hull. It helps the company and its clients complete dredging and transportation tasks efficiently with high stability and low operation cost.

During daily offshore dredging and reclamation operations, crew members operate a split hopper barge at a designated coastal dumping ground. After loading dredged silt, sand, and aggregates from the dredging site, the barge sails to the approved disposal area under the supervision of captain and engineers. To complete safe and efficient discharge, hydraulic systems open the hull longitudinally along the deck hinges, splitting the barge into two symmetrical halves. Gravity quickly releases all cargo onto the seabed for land reclamation or channel deepening. Once empty, the hull closes tightly, and the barge returns to the dredging zone to repeat the cycle. This design ensures fast unloading, high stability, and wide use in marine construction, port development, and waterway maintenance projects worldwide.

Our company exported a 1000m³ split hopper barge to the South American market. The factory assigned specialized engineers to handle installation and training, and the barge has been operating in excellent condition.

Qingzhou Yongli Mining and Dredging Machinery Co.,ltd had designed and produced a 600 Tons transport barge for Africa customer. The transport barge is finished and ready for shipment.

This is a fixed gold recovery plant with a capacity of 5 tons per hour, designed for efficient and continuous gold extraction. It is widely deployed by mining operators, contractors, and investors at alluvial or hardrock mining sites. The equipment runs stably during daily operation, feeding raw ore into the integrated processing system, where materials are screened, separated, and concentrated to capture fine gold particles. It delivers high recovery rate, low operation cost, and easy maintenance, helping users maximize output while reducing labor and energy consumption.

In January 2026, our dedicated production team at the factory successfully debugged and commissioned two custom-built gold washing plants, each with a processing capacity of 5 tons per hour. Designed to meet specific client requirements for efficient alluvial gold recovery, the gold washing plant underwent rigorous testing to ensure optimal performance and reliability. After confirming all systems were fully operational, the gold washing plant were securely packaged and promptly dispatched to the customer’s mining site, reinforcing our commitment to timely delivery and superior craftsmanship.

On November 25, China’s independently designed and built new-generation ultra-large trailing suction hopper dredger, the "Tongjun" vessel, successfully completed all its sea trial tests in the Yellow Sea and returned to dock at the Zhenhua Shipyard in Qidong, Jiangsu.
