Product Description

To cut the sea bed, the dredge Drag Head is equipped with replaceable teeth and water jet nozzles. The nozzles are placed at the front of the dredge drag head and used to cut the sand at the sea bed vertically, while the replaceable teeth are placed at the back to cut horizontally. The drag heads contributes to lower fuel consumption by having a low drag resistance, high production by mixing highest possible ratio of slurry, sand, clay and rocks with water efficiently.Marine steel head drags


Drag heads

Optimal dredging efficiency

The drag head on a trailing Suction Hopper Dredger is the first mechanical point of contact with the materials at the bottom. Its design, quality and sturdiness are critical to the dredging process. IHC Parts & Services has invested many years of practical experience and testing to create optimal drag head solutions, which are capable of extracting the maximum amount of soil from the bottom within the shortest possible time and at minimal cost.

While the production of excavated soil is primarily governed by visor width, penetration depth and trailing speed, other factors can also play a role. Drag head design is closely related to all the other key components of the dredging process.

Economic and technical considerations dictate the widest possible drag head consistent with other operational factors. The large degree of freedom of visor movement (up to 50°) increases the effectiveness of the Suction Pipe, and raises the level of production in both shallow and deep-water conditions. Optimal dredging efficiency at minimal lifetime cost is the key factor in the design challenge.
