Excavation dredge machine description
The excavation dredge machine we produce is self-propelled or non self-propelled,portable cutter suction dredger. The hull uses dismantle and box-like structure, Its dismantle type can be assembly at working place easily and be transported by road, railway and container accordingly, convenient in installation and working place moving from one to another. The power system can be designed to electric system or diesel engine driving system according to customers’ requirements.Equipment on the excavation dredge machine are as bellows: traversing device, cutter ladder lifting device, spuds and deck crane. The working process is as following: the cutter head cut the sand and mud underwater to mixture of slurry, then through dredging pump to the pipeline on dredger; at the end the slurry will be discharged by pipeline on land to the required place.
The design, construction, quality inspection is according to the standards and regulations of CCS. The steel plates are CCSB plates which meet the requirements of CCS. The welders are skillful and experienced and certified under the regulations of CCS. Anti-corrosion paints material are marine use under the requirements of CCS. The installation concentricity of diesel engine is less than 0.05mm. -----The diesel engine brand is Cummins or DEUTZ, which technology is from America and Germany. ------The pump brand is Kingda which technology is from Australia Warman. ------The gearbox is China famous brand Hangzhou Qianjin Advance Gearbox. ------The hydraulic system brand is Rexroth which technology is from Germany, ------The PLC system is from Germany SIEMENZ. ------The bushes are from Japan NSK. ------The sealings brand is Parker from America.
