Main features
Integrated system
CSD 400 features an integrated dredge pump & drive system. In other words, dredge pump is coupled with the gearbox, which is coupled with the engine. This makes the dredger more compact & efficient.
Exchangeable cutter teeth
The dredger’s cutter teeth are fixed to the cutter head through a bolt connection. This design ensures that they can be easily interchanged between three different types depending on the material to be dredged, or replaced when worn out.
Shallow draft
Cutter Suction 400 has a shallow draft of 1.1m. This is achieved due to its three pontoon design – one in the center and one on each side. The pontoons provide a floating capacity, which allows the dredger to easily operate in shallow waters.
Dismountable
For practicality and transport reasons, cutter suction dredger 400 is dismountable. More specifically, it can be taken apart into one central pontoon, two side pontoons, a control cabin, the spuds and the cutter ladder.
Transportable by road
Due to its dismountable design, cutter suction dredger 400 can be easily transported on a flat rack container by truck. This makes the transport process easier and cheaper in comparison to other large vessel transport methods.
Many customization options
We offer many customization options for the CSD 400. Some of these include hydraulic propulsion, spud carrier, tiltable spuds, anchor booms, automated system & production meter. If you have other requirements, do not hesitate to ask.
