Product Description

 18 inches Hydraulic Cutter Suction Dredger (LDCSD450)

The LDCSD450 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 to be easy to dismantle for transportation by road, rail or water, and is to be easy to reassemble at project site.The engines and dredge pump are located in the center pontoon. Two side pontoons serve as fuel bunkers,ballast tanks and storage tanks.
The dredger is powered by diesel engines. The main diesel engine is to drive the dredge pump and  the auxiliary engine is to drive hydraulic system, including cutter, swing and ladder winches, anchor winches,and the spud rams etc.
The spacious control cabin is ergonomically designed  with 360 degree view. All the operation buttons, switches, indicators, gauges are equipped on the control desk. Only one operator can control all the 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.
