Product DescriptionProduct DescriptionWhat is Trailing Suction Hopper Dredger? TSHD 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.Features of trailing suction hopper dredger1.The dredger hull can be an integral structure or split structure according to the model requirements.2. International famous brand, American and Chinese etc. engine3. Can be operated remotely in the operation room, with good all around visibility4. Full tested in factory before delivery5.

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. Dredger Hull manufacturingThe dredger hull 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.Ship Bulid Slipwayconstruction ship platformsconstruction ship platformsOur 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.Regarding After-sales ServiceWhat kind of trailing suction hopper dredger service guarantee is provided?After-sale serviceSpare parts:*Support spare parts are in stock.*We provides a convenient way for you to order parts.
