This post was last posted by Yuyu in the Desert on 2022-8-12 09:03 After the editor successfully jointly developed the first domestic 2500KJ double-action hydraulic pile driving hammer with Longyuan Zhenhua in 2019, on February 8, 2021, the 3500KJ hydraulic pile driving hammer developed by China Machinery Forging Jiangsu Co., Ltd. for the Guangzhou Salvage Bureau hit the South China Sea with one hammer. Its hammering energy is comparable to that produced in Germany. The Menck3500 produced by China Machinery Co., Ltd. ranks first in the world, marking that Zhongji Forging has the R&D, design, and manufacturing capabilities for large-diameter single-pile sinking and large-scale double-action hydraulic impact hammers for offshore wind power, breaking the long-term monopoly of foreign companies in this field, and truly realizing the localization and serialization of key and major equipment in core fields.
The YC-3500kJ ultra-large hydraulic piling hammer is my country's first independently developed fully hydraulic piling hammer. It is used for the foundation construction of large-diameter single-pipe piles for offshore wind power. Its hammer body has a total weight of about 800 tons, a hammer core weight of 175 tons, and a maximum impact energy of 3500kJ. It solves the "driving" pile problem in soil-based single-pile foundation construction and reaches the international advanced level. The cost is only 2/3 of similar foreign products. Key equipment from machinery to electrical, from hardware to software, etc. are all domestically produced. On March 16, the YC-3500kJ ultra-large hydraulic piling hammer developed by China Machinery Forging Press once again sounded in the waters of the CGN Jiazi Project. Every hammer was sonorous, powerful and powerful. The single pile end flange diameter of the wind farm is 7.5 meters, the pile length is 107 meters, and the pile weight is 1,600 tons.
On February 8, 2021, Huatianlong’s 4,000-ton main hook lifted the 3,500kJ hydraulic impact hammer purchased by the Guangzhou Salvage Bureau from China Machinery Co., Ltd. to hammer the first single pile in the South China Sea Wind Farm to the design elevation. Following the successful development of the first domestic 2500kJ double-acting hydraulic piling hammer in 2019, the 3500kJ hydraulic piling hammer developed by China Machinery Forging Press Jiangsu Co., Ltd., a subsidiary of Beijing Mechanical and Electrical Research Institute Co., Ltd., has been successfully tested again. Its hammering energy is comparable to that of the men produced in Germany. The ck3500 ranks first in the world, marking that domestic companies have the R&D, design, manufacturing and mass production capabilities for large-diameter single-pile sinking and large-scale double-action hydraulic impact hammers for offshore wind power. It breaks the long-term monopoly of foreign companies in this field and truly realizes the localization and serialization of key and major equipment in core fields.
