Recently, it was learned from CSSC that the “Marine Hydraulic Portal Crane†project independently developed by CSSC Huanan Ship Machinery Co., Ltd. won the only special contribution award of the 2010 Ganzhou Science and Technology Progress Award. The project broke the technical blockade of such equipment by foreign companies, filled the design and manufacturing gap of domestic marine hydraulic portal cranes, and successfully obtained the utility model patents approved by the State Intellectual Property Office. Compared with similar products at home and abroad, the main technical indicators of this product have reached the international advanced level. Therefore, the shipowners are favored and the sales volume is rising.
In 2005, in order to consolidate its position in the ship supporting market, find new economic growth points, and participate in international competition, South China Shipbuilding aimed at the domestic market demand, conducted a special market research on marine gantry cranes, and then initiated product development. Through research on this type of equipment, the company successfully launched a new product, and fully owns the independent intellectual property rights of the product. It also obtained the utility model patent approved by the State Intellectual Property Office in March 2009. It is understood that in the research and development of marine hydraulic portal cranes, the company has adopted a number of key technologies, such as the use of anti-overturning mechanisms to replace the balanced weight of the new design concept, the first successful implementation of the technology installed applications, fill the domestic The blank of the hydraulic portal crane anti-overturning rail. The design and application of the new anti-overturning mechanism enable the marine portal crane to balance the overturning moment without the need of a balance block, thereby greatly reducing the weight of the whole machine, simplifying the structure of the whole machine and reducing the volume of the whole machine. For the actual situation of manufacturing, installation and maintenance of conventional marine gantry cranes, and the unsightly appearance, the South China Shipbuilding Co., Ltd. adopts a highly integrated design scheme integrating the traveling mechanism and the overturning mechanism, the drive mechanism and the brake mechanism. The device has the characteristics of simple structure, compactness, reliable operation, high efficiency, beautiful appearance, convenient manufacture, installation and maintenance. In order to make the marine hydraulic portal crane have good operating performance, the company also applied hydraulic technology to the crane for the first time. All its actions are controlled by hydraulic technology, which makes the equipment have good speed regulation and buffer damping. Sex. In addition, the company's marine gantry cranes can also achieve single-machine long-span multi-point lifting operations. With the above technical features, marine gantry cranes are widely used in ships such as port work vessels and channel dredging vessels.
So far, South China Shipbuilding has developed and produced three series of marine gantry cranes such as MQ2500, MQ2800 and MQ3150. Its technology is at the leading level in China and has been widely recognized by users, and gradually occupied the domestic dredger. The market, its related technology is gradually being promoted and applied in the domestic pipelaying market. In the future, with the rapid development of engineering vessels such as channel dredging vessels, pipelaying vessels, and port operations vessels, the application of marine gantry cranes will become more and more extensive, and its market prospects are very broad.
