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.

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 (with China Hangzhou gearbox)1. High efficiency; reasonable design of lubricating and cooling system; running temperature is low;2. Alloy impeller, the flow-parts of pump are corrosion resistance;3. The bearing box is with good sealing;4. Easy disassembly and energy saving;5. Run smoothly, low vibration, large flow regulation range;6. Large transportation ability.Controlling 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. Cutter headCutter head type is crown-likeCutter head is driven by hydraulic motorBlade number is 5pcsCutter teeth quantity is 35pcsCutter teeth number is multiple and easily replaceableExceptional wear resistance, simplified maintenanceLow cost for productivityOptional Components1- Anchor boom2- Spud carriage 3-Discharge pipeline for dredgerAnchor boom (rod) system: is one of the important factors that directly affect production. The function of the anchor boom system during the construction process is to move the bolt forward to meet the requirements of cutter lateral movement excavation. Different dredgers have different anchoring methods. The operation is convenient and the anchoring speed is fast.Traditionally, dredgers need to constantly change the location of the cutter suction during operations in order to fully clean the target area. With the trolley system, by reducing the time for replacing piles, the dredger equipped with the trolley system can complete more workload in the same time. This technological improvement can increase the working efficiency of dredger by 5% to 50%, depending on the operating conditions and working methods.Pipelines: The pipeline is composed of HDPE pipe, rubber hose and floaters, which is connected to the tail of the dredger to transport the sediment suctioned by the dredger and discharge it to the shore.Packaging & Shipping1-Factory shipment and transportation2-Port dredger loading, transported by bulk carriersEach 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.Each dredger is detachable structure to facilitate transportation on the sea and land.Quality GuaranteeHow to control the quality of cutter suction dredgers? Testing before shipment in testing poolTo 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 waterRegarding After-sales ServiceWhat kind of dredger service guarantee is provided?After-Sales Service-installation, commissioning and training:*After delivery, we send experienced engineers who will be to guide the installation of dredger and train the operators.*Dredger will be tested for running 24 hours after the complete installation. Dredger test includes:Operation of the sand /mud dredging, Hydraulic and electrical system operating, Running of the dredger's outfitting equipment* 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. Ship successful export caseExport countriesThe product dredgers are exported to Russia, Kazakhstan, Kyrgyzstan, Uzbekistan, Egypt, Saudi Arabia, UAE, Yemen, Bangladesh, Indonesia, India, Pakistan, Brazil, Nigeria and dozens of other countries.
