Product Description

  8 Inch Dredger (LDCSD200)

LDCSD200 Cutter Suction Dredger of steel construction, the non self-propelled, dismountable type, is able to berth and dredge at any waters both in the coastal area and inland rivers.
The dredger can be used to excavate and transport cohesive sediment below the class III specified in code for dredging engineering construction technique issued by Ministry of Water Resources(MWR) of P.R.China.
In the course of technical designing, we have considered special requirements for local tropical climate conditions such as meteorological and waters distributing state etc.
It's hull consists of a main pontoon and two side pontoons, which is easy to dismantle or mount for transportation by road, rail or water, and is easy to reassemble at project site.The engines and dredge pump are located in the center pontoon,the two side pontoons serve as fuel bunkers,ballast tanks and storage tanks.
The dredger is powered by diesel engine. The dredge pump is driven by the engine through the gearbox. On the gearbox, two hydraulic pumps are equipped, to supply power for all the hydraulic equipment such as cutter, swing and ladder winches, and the spud rams etc.
The spacious control cabin is ergonomically designed  with 360 degree view. All the operation buttons, swifts, indicators, gauges are equipped on the control desk. Only one operator can control the whole dredger in the operation room.
The dredger is painted by 4 layers of marine paint to protect from the corrosion. The ZINC anode can be used to give better anti-corrosion function.

Working Principle

A sand dredger's (CSD) suction tube has a cutter head at the suction inlet, to loosen the earth and transport it to the suction mouth. The cutter can also be used for hard surface materials like gravel or rock.The dredged sand is usually sucked up by a wear-resistant centrifugal pump and discharged through a pipe line on to the land. Sand dredger is a good choice for dredging activites.


CSD series dredgers can apply to all kinds of soil structures and can be widely used in mineral digging,port(channel) dredging and reclamation works.


By absorbing advanced technology of Dutch and American related products,this series of dredgers have advantages of rational design,all hydraulic control,simple operation,little maintenance and strong power.The capacity of CSD dredgers rangs from 100m3/hr to 1000m3/hr,the dredging depth from 1m to 25m and discharge distance from 500m to 3000m which can satisfy different work demands.
