Suction dredgers come in various sizes, with hull and production capacities ranging widely. Dredgers with a capacity of 120m³/h or less are generally categorized as small dredgers, suitable for operations in shallow water canals, small rivers, and lakes. Dredgers with a capacity between 200 to 500m³/h are considered medium-sized, ideal for deeper river channels and estuarine areas. Dredgers with a capacity of 500m³/h or more are classified as large dredgers, known for their strong wind and wave resistance, making them suitable for coastal construction.Turbine dredger cutter
