The cutter dredgers are used for sand mining purposes. The cutter dredger has a welded engineroom as body and this body is built above or under water table. Above the engine room is the control room situated.
The movement of the cutter head is up and down and from left to right which is accomplished by cylinders. In this manner the cutter unit has the possibility to sweep instead of moving the complete dredger.
On both sides are 2 square floaters. These cutter dredgers can be equipped with an electric or hydraulic cutterhead which has cutting knives or teeth installed. This dredger is easy to transport by containers.
