The setting of the sight glass is required to ensure the bottom profile can be followed. More or less seawater is allowed into the suction head by using the water flaps. This regulates the vacuum. The hydraulic control system is installed in a manifold block. This is equipped with a watertight housing. High requirements are set because the suction head is dragged over the sea bottom especially in the area of seawater resistance, watertightness and robustness. The active drag head is used on dredgers. Hydrauvision designed and built the control blocks with the watertight housing for the relatively small new drag heads for this project. Hydrauvision also delivered the installation on the drag head including stainless steel pipework and hoses.
Dredge drag head is used by trailing hopper suction dredger to collect sand from the sea floor.
