Product DescriptionProduct DescriptionWhat is cutter suction dredger? Type: The dredger is made of marine steel construction, self-propelled or non self-propelled with dismountable type.Structure: The dredger is consisted with three pontoons, one main pontoon (engine room with diesel engines, dredging pump, generator and hydraulic system etc.), and two side pontoons.Size: All parts are dimensioned to allow the dredger to be transported by truck.Connection: The dredger is equipped with a rapid connection-disconnection system for the pontoons, the deck is fastened with bolts, and the front and rear bottoms of the hull are reinforced with hooks.Power: The dredger is powered by one main diesel engine and one auxiliary engine, and the main diesel engine drives the dredging pump and the auxiliary engine drives hydraulic system.Working principle: The main engine provides power, then the gear box will transit it to the sand pump, the former is driven to rotate and create vacuum in suction pipe. In this way, the mixture composed of mud, sand and water by the cutter head is sucked into the sand pump through the inlet pipeline, and then discharged by the pump to the appointed place through outlet pipeline which is connected to the outlet of the sand pump.Features of Cutter Suction Dredger1.
