Cable systems
Cables offer an optimal solution for reducing the weight of bridges while enhancing their span, leading to material savings and a reduced environmental footprint. Additionally, their use contributes to shorter construction timelines.
Stay cable bridge
OVM AT Stay Cable System for Extradosed Bridge
Extradosed Bridge is also called “partially cable stayed bridge”, It combines the characteristics of cable stayed bridge and continuous girder bridge. The load on bridge is resisted by both cables and girders. It features economic, aesthetic, good rigidness and easier construction, etc.
The first extradosed bridge was built in 1994 in Japan. OVM subcontracted the very first extradosed bridge (Zhanbei Bridge) in 2001 in China. With continuous improvement on it, OVMAT Stay Cable enjoys technical and economic advanced and wins high and wide recognition. OVM has involved in construction of 100+ extradosed bridges worldwide since 2001. Through which, OVM has accumulated abundant experiences on its cable system designing, supplying and application, and bridge construction and management.
OVM AT Stay Cable System is extended on basis of the excellent performance of OVM250 Multi-strand Stay Cable System. By successfully adopting an innovative patented individual-pipe saddle which have strands individually and intactly passing through the saddle, it well maintains PE sheathed strand’s anti-corrosion performance and remarkably improve stress condition around saddle on pylon. OVM’s patented anti-slip device fits on saddle end to effectively transfer the bilateral deflect load of cable to pylon. OVMAT Stay Cable System is capable of single strand adjustable and replaceable.
Anti-slip key type
• Each strand is individually placed in saddle pipes and parallel to each other.
• Each strand is fixed with an anti-slipping key.
• It can resist and transfer the bilateral deflecting force during the cable service period.
• The single strand is replaceable.
