Download brochure

The Multifunctional Dredger with both WATER JET and CUTTER function can be used in soft and hard layers for the cleaning of rivers, ponds and sand mining purposes. One dredger for all types of soil.

The main advantage is the submersible dredge pump which is located on the dredge pipe to generate the highest efficiency. Another advantage of this dredger is the possibility for the changing of the dredge system during work.

This changing can be done easily with the cranes which are mounted on both sides of the dredger. Also the anchors and spare parts can be lifted by this crane what guaranteed an ergonomic working.

The dredger is build compact so the cost are low and the construction is designed to make transport by sea freight containers possible. So this Multifunctional dredger is the perfect machine to dredge in an environment with a changing soil.
