A Cutter Suction Dredger’s (CSD) main and most important asset is its cutterhead. The cutterhead largely defines the performance of the dredger as it is responsible for the excavation of the soil/rock and the creation of slurry. In the past 25 years Niron Staal has gained the knowledge and know-how in the fabrication and assembling of various types of cutterheads. Since 1971 In close partnership with our clients, designers and end-users Niron Staal has produced more than, almost 750 one-offs and small series of cutter heads.

Our main construction hall is outfitted with in total four manipulators of which two have capacity of up to 30T and two with capacity up to 60T, the largest manipulators worldwide used for the production of cutterheads. The benefit of these manipulators is that the cutterhead can be assembled and welded from any type of angle and that all specialized welding of for example the adapters or blades can be done with the highest accuracy and quality. The welding process and assembly of cutterheads has been perfected over the years and has become a specialism of Niron Staal.
