On December 28, 2014, Yinghua Bridge, located in Nanning, capital of southwest China's Guangxi Zhuang Autonomous Region, was completed and opened up to traffic. The construction of the bridge is of great significance to carrying out the general urban infrastructure plan and expanding urban space. Moreover, the successful application of the S-shaped steel wire wrapping machine marks a further step forward in the exploration of new equipment and technologies of bridge construction.

Yinghua Bridge, which is 1,018 meters in length, 38 meters in breadth and 410 meters in main span, is a single main cable suspension bridge with twin towers. It's the first suspension bridge in Nanning and the second single main cable ground-anchored suspension bridge in China. Inspired by antique sheep-horn chimes-relics from Han Dynasty (202B.C.-A.D.220) unearth in Puxi County of Guangxi, the designer integrated classic charm with modern feeling when building the bridge, fully displaying the local cultural temperament.

Aside from aesthetic feeling, the bridge also gives people a sense of safety. Lifted by a single steel cable and intensified by an anchorage system applying a high-strength steel pull rod and both S-shaped and round steel wire wrapping machines, the bridge has no parallel in the history of bridge construction.

According to China Tiesiju Civil Engineering Group, the general contractor of Yinghua, it was the famous bridge cable system solution provider Liuzhou OVM Machinery Co. Ltd. that supplied the key material including main cable, catenary wire, cable saddle and anchor system and carried out the main cable wire wrapping anti-corrosive construction.

S-shaped steel wire anti-corrosion technology, which can prolong the life of the bridge and make it safer, has been independently developed by OVM Machinery and has just begun to be applied domestically. Yinghua Bridge is among the handful of application examples.

"The wrapping of S-shaped steel wire can effectively shield the main cable from the corrosion of rain and fog condensate and prolong its service life. Besides that, the S-shaped steel wire wrapping in combination with surface coating can intensify the dehumidification system of the main cable.

The machine has been applied in the round steel wire wrapping of the main cables of Fuling Qingcaobei Yangtze River Bridge, Bengbu Daqinglu Huaihe River Highway Bridge and Liuzhou Shuangyong Bridge. Yinghua Bridge is the first example of the application of the S-shaped steel wire wrapping technology.

OVM Machinery started the wrapping work for Yinghua Bridge on November 4, 2014 and quickly concluded it on November 30. Credit goes to the convenience and high efficiency of the wrapping machines.

An executive from China Tiesiju Civil Engineering Group said the application of the S-shaped steel wire proved that OVM-made wrapping machines is capable of replacing the similar products manufactured by foreign companies that once monopolized the domestic market and have become leaders among Chinese manufacturers.

Over the course of becoming a "bridge power", China will see a surge in the demand for new material, equipment and technology for bridge construction. OVM Machinery will catch up by providing the market with yet more state-of-the-art products and services.
