Liugong example verification! Owim strip cable and Anshan steel strand stay cable pass international authoritative test

In the near future，The cable with saddle steel strand, independently developed by Liugong Owim Company, has completed severe axial fatigue in China Shipbuilding Industry Metal Structure Test and Inspection Center./Tensile test，And Ben fatigue/Tensile test，Successfully passed the latest specifications of the International Concrete Associationfib bulletin 89 Requirements for fatigue performance of cable with cable saddle，It shows the excellent R & D strength and excellent manufacturing technology of Liugong Owim Company in the field of bridge cable.，It is also a strong evidence of the superior performance of Owim's stranded cable products.。

In practical work，The cable is not only subjected to axial load，Also subject to construction error、Sag、The lateral bending load is caused by the change of line shape caused by temperature and the vibration excited by external environment.。Specifications issued in 2019fib bulletin 89，Axial Fatigue of Stay Cables of Anshan Steel Strand with Cable/Tensile test was optimized.，At the same time, it increases the bending fatigue of the stay cable of Anshan steel strand with cable./Tensile test requirements。In the course of these two challenging experiments,，Owim 37-hole Angang strand cable withstands 2 million axial load cycles，It shows the extremely high fatigue resistance of the cable system.；In the bending fatigue and tensile test simulating the actual engineering application scenarios, the 19-hole Angang stranded cable with cable was tested.，This further demonstrates the excellent toughness and durability of the cable system。The test results show that，Fatigue properties in both axial and transverse bending，The products of Liugong Owim Company have broken the traditional technical barriers.，It has achieved a major technological breakthrough in this field.。

The success of the experiment，It not only established the leading position of Liugong Ovim Company in the prestressed steel strand cable industry, but also established the leading position of Liugong Ovim Company in the prestressed steel strand cable industry.，It also laid a solid foundation for the company to expand a larger international market.。Liugong Owim will continue to provide high-quality construction projects around the world.、Reliable solutions for prestressing systems。
