There are two kinds of the dredger:cutter suction dredger and rotating dig type dredger.It is easy to operate,move and strong to adapt.It is used the hydraulic system. The machinery is suitable for river channel cleanout,park,pool,fishing pool,salt field and so on. cutter suction dredger broad range of applications in operations in the rivers and lakes for the dredging, channel excavation, hydraulic fill create land. In exceptional circumstances a cutter suction dredger cutter installed on the high-power devices, can be excavated without blasting rocks such as basalt and limestone strata. (2) cutter suction dredger high efficiency, large output, pump from the well. Large-scale production of a cutter suction dredger of up to several thousand cubic meters per hour; the sand, or crushed rock material to rely on a strong driving force through the mud pumps and mud pipeline, pumping out a few kilometers outside. (3) cutter suction dredger is simple, easy to control. Stern of the dredger on the steel piles trolley position and stepping, the use of measuring cable cutter arm 2 Trench 2 measured with the fixed anchor, by hinge traction, hatchback swing cutter cut sediment materials, in the must work under the control of the swing angle, the twisting movement of the material, after losing to the accumulation of mud tube pump field. Step dredger piles alternately by the two campaigns move forward. The following is one 1000m3/h dredger specification, with dredgering depth is 14m.
