The self-propelled sand dredger features a dual-pump parallel system that can simultaneously handle two discharge pipelines, doubling the sediment transportation efficiency compared to single-pump designs. The 12-inch large-flow centrifugal sand pump is equipped with wear-resistant ceramic liners that extend service life by 45% in high-abrasion sand mining environments. The self-propelled power system allows the dredger to move between operation areas without external towing, reducing construction waiting time. Its Beidou positioning system enables real-time monitoring of dredging position and sand extraction volume, making it easy to manage construction progress and comply with mining quota regulations.
Overall dimensions: 35m (length) × 7.2m (width) × 2.8m (draft); Maximum dredging depth: 22 meters; Rated sand pumping capacity: 500 cubic meters per hour; Main diesel engine power: 380 kW; Operating empty weight: 72 tons; Fuel tank total volume: 8000 liters; Pump diameter: 12 inches; Maximum navigation speed: 12 knots; Maximum sediment discharge distance: 450 meters; Control mode: Full hydraulic remote control + Beidou positioning; Hull thickness: 16mm; Pump liner material: High-alumina ceramic
This self-propelled sand dredger is applicable to river sand mining, coastal滩涂 dredging, reclamation project supporting, offshore shallow sea sediment removal and sand resource extraction. It is ideal for sand mining enterprises, water conservancy construction teams and reclamation project contractors. It can meet both commercial sand extraction needs and ecological sediment removal requirements, providing flexible and efficient solutions for large-scale water area construction projects.
