And it is sandblasted and painted by 4 layers of marine epoxy paint suitable for saltwater service. The zinc anode can be used to give better anti-corrosion function. All dredgers are made of special marine steel plates, which have been certified by CCS.Marine Diesel Main EngineThe dredgers are equipped with world famous powerful engine, which are famous for it's durability, lower consumption, standardized accessories and easy maintenance. Power from 100-2500kW or as required.The engine brand we use are all global warranty, spare parts can be available in short time. It's durability, environmental protection and lower consumption, standardized accessories and easy maintenance. Dredge pump in cabin (with China Hangzhou gearbox)Our dredge pump is made of China famous brand Shijiazhuang pump, using international advanced technology of marine dredging pump, is a new type slurry pump. With China Hangzhou gearbox. *Simple and reliable structure, easy disassembly and maintenance* Anti-wearing and anti-corrosion, long life for wearing parts*Good performance, strong suction capacity, digging deep, high concentration of dredgeControlling systemWe use PLC Siemens controlling system. The dredger through the PLC system to control the hydraulic transmission device, including cutter, winch, hydraulic cylinder etc.Operation console is set in the operation room, and the operation of all equipments of the dredger can be remotely controlled in the operation room. Hydraulic systemAn integral hydraulic system includes hydraulic cutter head, hydraulic winch, hydraulic pump, hydraulic valve manifold, solenoid valve, hydraulic pipes, hydraulic components, electrical actuator and so on. The hydraulic system requirements are very high and strict, it is the main artery of the entire dredger. The swing winches, lifting winch and cutter head are all driven by separate hydraulic motors. Optional componentsAccording to the customer's requirements, optional components can be selected for the customer to choose, and the work efficiency for the customer can also be provided.1-Anchor boom;2-Spud carriage;3-Swivel joint;4-Hydraulic titling spud;5-Onshore booster pump;6-Floating booster pump;7-Dredging pipeline (HDPE pipe, rubber hose, floater);etc.Packaging & ShippingFactory shipment and transportationEach dredger is detachable structure to facilitate truck transportation on land. Depending on the size, some models of dredgers can be disassembled and transported through containers, some models can be disassembled and transported through bulk carriers. Simple disassembly and fast installation.How to control the quality of jet suction dredgers?Testing before shipmentTo ensure the good performance and safety, each ship must undergo complete test before leaving the factory, and it is tested like the machine working in the customer's working site. There will be test records during the testing process of dredging performance and safety. After testing, the dredger is sent to the customer's work site for installation and can be directly put into use. Usually, the customer can supervise on site during the dredger testing period. Including: -Condition of electricity connection-Operation conditions of hydraulic system-Engines running and power capacity-Mechanical dredging work-Dredging pump rotates at different speed with fresh waterDredger Test Certificate by CCSRegarding After-sales ServiceWhat kind of dredger service guarantee is provided?1-After-Sales Service-installation and training:*After delivery, we send experienced engineers who will be to guide the installation of dredger and train the operators.* Our engineers will provide technical training on dredger for customers' workers, how to operate the dredger and daily maintain the dredger until the workers learn it.2-After-Sales Service-warranty and maintenance:*We provide free warranty and on-site maintenance service for a period of one year after commissioning.*24/7 technical support standby.
