Product Description
Sliding Piece For Trailing Suction Hopper Dredger
Product Introduction
The sliding piece, commonly known as the draghead visor or suction mouth, is the critical interface between your Trailing Suction Hopper Dredger (TSHD) and the seabed. As the primary component responsible for fluidizing and excavating material, its design and durability directly dictate the efficiency of your entire dredging operation.
Our state-of-the-art Sliding Piece is engineered for extreme marine environments and high-production dredging. Designed to optimize the water-to-soil mixture ratio, it ensures maximum intake of solids while minimizing water ingress, thereby reducing fuel consumption and cycle times.

Key Features & Benefits
*Superior Wear Resistance: Manufactured from high-tensile abrasion-resistant steel (such as Hardox or equivalent), our sliding pieces are built to withstand the constant friction of sand, gravel, and rocky seabeds, significantly extending operational lifespan.
*Optimized Hydrodynamics: The ergonomic curvature and internal vane design create a powerful Venturi effect, ensuring a dense and consistent flow of slurry into the suction pipe. This prevents clogging and maintains steady production rates.
*Modular Wear Parts: Critical wear zones are fitted with replaceable wear grids, teeth, or shrouds. This modular design allows for quick on-board maintenance and replacement, minimizing costly dry-dock downtime.
*Universal Compatibility: Available in various sizes (from 500mm to 1400mm+ suction pipe diameters) and configurations. We can customize the mounting points and hydraulics to retrofit seamlessly with IHC, Damen, or custom-built dragheads.
*Adjustable Visor Mechanism: The sliding mechanism allows for precise control of the intake opening, enabling the dredge master to adapt instantly to changing soil conditions—from loose sand to compacted clay.
Applications
Ideal for Capital Dredging, Land Reclamation, Maintenance Dredging, and Offshore Sand Mining.
