耙吸挖泥船 Drag Suction Dredgers

In the early 90s of last century, the demand for drag suction dredgers to China’s dredging industry is extremely urgent with the realignment of Changjiang river, especially, the import price of whole dredger is extremely high, so it is the only way leading to dredging industry growth to design and build drag suction dredgers by own efforts in China.

Changjiang Hydrographic Bureau of Ministry of Communications created a new situation to design and build drag suction dredgers in China and established public, impartial global bidding for dredging equipments, that enhancing comprehensively the advanced nature of domestic drag suction dredgers and the global synchronization. Our company take the lead in acceptance of the bid to design and develop completed hydraulic systems, which was matched successfully to a 1,500m3 drag suction dredger of Changjiang Hydrographic Bureau of Ministry of Communications, since then we also supplied completed hydraulic systems to Shanghai Hydrographic Bureau for matching three large drag suction dredgers “Xinhaixiang”, “Xinhaijing” and “Xinhaishi”, which is a series rebuilt project from cargo ships to drag suction dredgers, that has begun the prologue of building large drag suction dredger for domestic dredging industry.

The 8,000m3 large drag suction dredger is the first ship to design oneself with independent intellectual property rights, on which we supplied successfully integrated hydraulic systems and equipments possessing the global synchronization advanced technologies, that enable us to keep leading technology level in the field of large drag suction dredger hydraulic systems.

At present, our integrated hydraulic systems for drag suction dredgers have formed standard series products with the specifications of large-, middle- and small-size and different grades of high-, central- and low-grade, including hydraulic oil cylinders, hydraulic winches, hydraulic control valves, electronic control hydraulic systems and the like, so as to meet the needs of every customer on different demands and various special functions.

 

 

    上世纪90年代初,随着长江整治,疏浚行业对耙吸挖泥船的需求极为迫切,特别整船进口价格极高,为此我国自行设计建造耙吸挖泥船成为疏浚行业发展的必由之路。交通部长江航道局开创了我国自行设计建造耙吸挖泥船之路,并确定了疏浚设备的公开,公正的全球招标,全面提升了我国耙吸挖泥船的先进性与全球同步性。我公司中标为交通部长江航道局1500方耙吸挖泥船成功配套设计供应液压成套系统,同时随着我公司为上海航道局“新海象”、“新海鲸”、“新海狮”的货改耙液压成套系统的设计配套成功,拉开疏浚行业大型耙吸挖泥船国内制造的序幕,为国内第一艘自行设计并具有完全独立的知识产权的8000方大型耙吸挖泥船配套具有全球同步先进性的液压成套系统设备的成功使我公司在该领域保持技术领先。目前,公司已形成大、中、小型不同规格,高、中、低档不同档次的耙吸挖泥船液压成套系统,包括油缸、液压绞车、液控阀门、液压电控系统等标准全系列产品,完全能够满足所有客户的不同需求及各种特殊功能。
