Product DescriptionGeneral Description of Trailing Suction Hopper DredgerTSHD Trailing suction hopper dredger is a ship that has a full sailing capacity used to maintain navigable waterways, deepening the maritime canals that are threatened to become silted, to construct new land elsewhere or to replace sand eroded by storms or wave action on the beaches. This is made possible by large powerful pumps and engines able to suck sand, clay, silt and gravel.Trailing suction hopper dredger is mostly used for maintaining the depth of a harbor, canal or waterway, constant delivery of sand for land reclamation or beach nourishment.Trailing Suction Hopper Dredger Features:1. Customized designs will be made based on customers' project requirements. Our engineers are all experienced in dredger designs for many years. The cooperation with China leading ship design institutes and professional colleges help us to ensure the design quality.2. All the JUNHANG dredgers are built by skilled workers and inspected strictly to assure the high quality and durability. Each finished dredger will be fully tested at our launching site before delivery to make sure it work smoothly when delivered to customers.3. Best parts will be used for the dredgers, like world famous American engines, Shijiazhuang pumps, Hangzhou gearboxes, Simens PLC control system.4. Hydraulic system is one of the most important parts of trailing suction hopper dredger. The drag head, lifting winch, swing winches, anchor arm are driven by hydraulic motors for higher efficiency and durability. Reputed brands are used for the other hydraulic parts like hydraulic pipes, hydraulic pumps, hydraulic valves.5. The dredgers are dismountable. So they can be disassembled and assembled easily. Thus it is convenient for the transportation by road, rail or water.6. Professional engineers will be sent to the project site to insist the customers on the installation, commissioning, testing of the dredgers and training of operators.Technical Specifications500m3 Trailing Suction Hopper Dredger Technical SpecificationModel No.JUNHANG-TSHD5001Total Length52.0m2Lengthbetween perpendiculars49.0m3Hullwidth12.0m4Hulldepth4.5m5Full load maximum draft3.5m6Empty load draft1.0m7DredgingDepth15m8Dischargedistance1500m9Storage capacity500m310Ship weight800 tons11Propulsion Engine Power357KW *212Engine for dredgingpump300KW *213Sand dredging pump2000m3/h14Crew15P15Speed10kn16Height of the mud tank bulkhead2.5mCompany StrengthJUNHANG Company has taken the lead of passing lSO9001:2009 International Quality System Certification & the General Ship Production Enterprise Technical Condition Evaluation Certificate issued by ZC, CCS to provide our customers with dredger products of high standard & quality.

All to further improve operational efficiency and sustainable performance.Professional team for dredger:20 senior engineers specializing in ship building and dredging research10 mechanical designers and construction engineers10 quality inspection engineers20 after-sales service techniciansImportant Core Component DescriptionDrag headThe drag head is located at the forefront of the pipeline of the trailing suction hopper dredger, which is loosened and sucks in sediment through the vacuum action of the mud pump. The sediment enters the mud tank through the drag pipe and sediment transport pipe, achieving simultaneous navigation and operation. Its efficiency is affected by the structure of the rake head and the power of the mud pump.Mud storage tankWhen the dredger is in operation, the suction pipe is lowered to the riverbed. Utilizing the vacuum effect of the mud pump, the mud is sucked from the riverbed by the rake head and the suction pipe and is then collected into the mud storage tank of the dredger. Once the mud storage tank is full, the rake is raised and the dredger sails to the dumping area to open the mud valve to discharge the mud, or the excavated soil is directly discharged outside the vessel.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. Marine Diesel EngineInternational famous brand engine, multiple options are available for selection1. Large power, low consumption;2. Run steady, marine diesel engine with seawater and fresh water heat exchanger;3. With gearbox to adjust the speed;4. Main engine and auxiliary engine collaborative;5. Located in engine room, enough space for maintenance.Ship Bulid SlipwayOur company is equipped with 12 sets of various lifting equipment below 200 tons, as well as 10 construction ship platforms. The company has the ability to construct various steel ships below 3500 tons and undertake the construction of large and medium-sized land reclamation projects.Build on PlatformBuilding in the shipyard platform, the hull is formed.Regarding 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. If customer's dredging experience unskilled, equipment failure or customer needs to solve the dredger small problem, we will send our engineers to customer's working site to inspect and repair at any time.Our foreign cooperative clientsThe visits of foreign clientsIn order to make our clients satisfied, we sincerely invite clients to visit our factory and realize our research team and products, clients' technical questions we all give the solutions by engineer, by this kind of communication, clients are confident to our products and after-sales services.(8).
