September 5，New Chaohu-Ma'anshan Intercity Railway Ma'anshan Rail-cum-Road Yangtze River BridgeCMSG-Main branch channel bridge of Bid 1ZFirst acceptance meeting of stay cable of No.3 main tower was held。

Discussed by experts at the meeting，Designed by Liugong Owim Company、The first stay cable of Maanshan Highway and Railway Yangtze River Bridge（SS1－B－2）Quality meets design document、Technical specifications and relevant standards、Specification requirements，First article acceptance is qualified，Can be used for subsequent mass production。

The main bridge of Maanshan Changjiang River Rail-cum-Road Bridge adopts the main span(2×1120)M Three Tower Steel Truss Girder Cable-stayed Bridge，The total length is 3248 meters，It is the world's first three-tower cable-stayed bridge with double main spans exceeding 1000 meters and the world's longest steel truss cable-stayed bridge.，At the same time，It is also the first in the world to use tensile strength 2100.MPa、Stress amplitude 280MPaBridge with parallel steel wire stay cables。

Due to the large scale of the Maanshan Rail-cum-Road Yangtze River Bridge project,、High technology content、The construction environment is complex、The construction is difficult，Higher requirements are put forward for the strength and manufacturing technology of stay cable steel wire.。

Before，Liugong Owim Company has carried out a lot of R & D and innovation on technology and process for this project.。It is carried out by Liugong Owim Company as the leading unit of scientific research.《2100MPaResearch on Key Technology of Anti-fatigue Durable Parallel Steel Wire Stay Cable》The project has been confirmed by the experts of the project review meeting.，The overall results of the project have reached the international leading level.，It can strongly support the construction of Ma'anshan Highway and Railway Yangtze River Bridge.。

The Maanshan Rail-cum-Road Bridge is an important part of the Chaozhou-Maanshan Intercity Railway，The high-speed rail line connects the cities of Maanshan and Hefei in Anhui Province.，After completion, the transport capacity will be further enhanced.，Promote the integrated development of the Yangtze River Delta。Liugong Owim will always adhere to the customer first.，Help the smooth construction of the bridge with excellent products and services。
