100t Heavy Anti-seismic Spherical Bearings of Sunrui Special Equipment Smoothly Delivered


  At the end of August,4 anti-seismic spherical bearings manufactured by Sunrui Special Equipment with the bearing capacity of 145000KN were successfully completed and delivered to the Shangqiu-Hefei-Hangzhou High-speed Railway Huaihe River Bridge project.

  Huaihe River Bridge is the most important control project of Shangqiu-Hefei-Hangzhou High-speed Railway.Shangqiu-Hefei-Hangzhou High-speed Railway is the largest high-speed railway line in the 13th Five-year Plan of the country,an integral part of the Beijing-Kowloon High-Speed Railway passenger dedicated line,and also the most important passenger dedicated line of the"Second Channel in East China."The geographical and strategic location of this line is important.With the densely populated cities along this line,it's the most important transport artery connecting the Central China,Yangtze-Huaihe Region and the Yangtze River Delta.With a total length of 452m,this is a ballastless track continuous steel arch bridge,ranking the first in the world.According to the plan,the Huaihe River Bridge will be completed by the end of January 2019 and the railway track will be laid in May.It is expected to open to traffic by the end of 2019.

  Through early effective communication with the design unit,the project team members of Sunrui Special Equipment have fully grasped the customer's needs.Relying on advanced technology research and development strength,and through the design adjustment of the product,they have met customer's requirements for product performance,enabling the product's smooth selection and application.The main pier of the Huaihe River Bridge adopts 145000kN ball bearings.In the process of design,in order to meet the anti-seismic demand of the bridge,the research and development team of the bridge building safety equipment adds 2 device structure optimization designs,to achieve the requirements of the bridge design for the bearing performance.With the bearing capacity of 145000KN,the total weight of a single bearing is 100t and the largest plane size is nearly 5m.In the whole process of production,such technical difficulties have been overcome as the super-tonnage blank casting,machining,hoisting,slide fragment inlay,and the stainless steel molding of the spherical surface,which ensured the smooth delivery of the product.

  In face of the adverse factors including tight production schedule and difficult process,Sunrui Special Equipment's bridge building safety equipment industry department has guaranteed smooth delivery and usage of the product through combined process and reasonable arrangement of workshop schedule.

  According to HePinggen,director of bridge building safety equipment industry department,Sunrui Special Equipment has won customer's trust with its advanced technology and excellent service,which is of great significance to get rid of the homogenization competition in exchange with low price for market.The successful delivery of the bearing product of this project has further built up the market dominance of Sunrui Special Equipment in the special large bridge bearing design and seismic mitigation and absorption products.Through the strict quality control,the product has been delivered successfully to use,establishing a good image and reputation for Sunrui Special Equipment.It is of great significance for Sunrui Special Equipment to base on technical advantages and maintain and improve the product quality,so as to enhance its brand reputation and stabilize its position in industry.
