Dredge Yard - Drag Head

Drag head of Dredge Yard are equipped with adjustable visor to allow the best performance according to each job. The visor can be adjusted according to the dredging depth, soil type, trailing speed and teeth configurations.

The Drag Heads are equipped with replaceable teeth mounted on the visor to penetrate the soil and loosen the sand and cut clay for optimal production. The teeth are available in three types according to the dredging area. They can be pick point or narrow chisel and wide edge wide chisel.

In the heel of the Drag Head jet water nozzles are mounted to inject water in the soil by which ground material is cut and loosened.

On both the main body and the visor of the drag head wear resistant liners are mounted where there is direct contact with the soil, to avoid excessive wear and achieve a long lifetime. These wear resistant liners can be replaced when worn.

On the visor an adjustable water flap is provided to regulate the water inflow.

The main body and visor of the drag head are both made from high tensile steel and stiffened according to Dredge Yard Finite Element Analysis. The complete drag head is designed for easy maintenance and handling.

The drag head is designed by using Fluid Dynamic Simulation to allow the best flow and lowest resistance during trailing.
