A classic architecture of naval dredging equipment that combines certain advantages of using a submersible dredging equipment: more productivity and less cost. This solution is suitable to perform dredging operations on very compact land. the lifting of material is made by the combined action of the excavators, fixed to the pump at the end of the ladder, that disgregate the layers of sea floor.
