DRAGFLOW has supplied a Dredging Cutter Head (DTM85), directly connected to the pump (HY85HC) for a coastal protection project which took place in Bibione.

In order to counteract erosion, the customer needed to dredge the sand from the seabed and to pump it on the beaches. A coastal protection project for which an excavator was already available.

We have proposed a HY85HC hydraulic pump and a matching DTM dredging cutter head. The unit thus constituted was mounted directly on the mechanical arm of the excavator already in the customer’s possession.

The DTM cutter head can be used in combination with the agitator, which allows to avoid clogging problems to the pump.

The DRAGFLOW Dredging Head can be used with all DRAGFLOW hydraulic systems and is able to increase efficiency, especially in the presence of hard and compact materials.
