Trailing Suction Hopper Dredger is an equipped with rake head mining machinery and hydraulic Dredging Equipment of large self-propelled, binning Dredger.Dredging, will put down the bottom of the river, the suction pipes, using vacuum effect of mud pump, through the rake head and Suction Tube bottom absorbing mud into the dredger mud in the warehouse, warehouse full of mud, after sailing up the rake to spoil area open the mud disposal, or directly to dig up the dirt out of the ship. Some dredger can also be unloaded in mud warehouse of soil to suck out of land reclamation. It can have good navigation performance, self-propelled, since the load dump, and in the work in the navigation state, don't need a positioning device. It is suitable for no cover, long and narrow coastal approach channel excavation and maintenance, with most efficient when excavation of silt.
Trailing suction loading dredger, basically is a kind of dredging boat from the bottom of the sea, the dredging method is similar to vacuum cleaner. The ship is equipped with one or several centrifugal pump, using centrifugal pump suck up water and mud from the bottom, hopper into the ship. These operations on the voyage, air while digging, hopper filled with mud is to throw mud area, through the Bottom Door handle cases out of the mud. All ships of trailing suction hopper with its capacity to show different size, general capacity is 500 ~ 1000 m3. The smallest trailing suction can ship construction. Under the condition of the water depth around 3 largest trailing suction vessel dug deep can reach more than 3 ~ 35. The trailing suction vessel to vessel, can be in the wind and waves considerable dredging, navigation and throw mud at sea.
