Dredge Heavy Duty Active Drag Head for TSHD Dredger

Hi-sea Dredge Heavy Duty Active Drag Head is to excavate the soil and transform it and the seawater into a mixture. The higher the density of the mixture the drag head can create, the better it is performing. Furthermore, the drag head represents the first mechanical contact with the soil, so its design, quality and sturdiness are critical in dredging tasks. Ongoing development has resulted in active soil excavation by the drag head, either with water or teeth.Hi-sea has invested many years of practical experience and testing to create optimal drag head solutions for extracting the maximum of bottom soil at minimum time and cost, and continues to do so.
