Modular expansion device

The Modular Expansion Joint System is a mechanical device installed in bridge expansion joint openings. The main function is to allow the vehicle to travel smoothly
through large expansion joint openings. It does this by dividing the large expansion joint opening into a series of smaller openings called cells.
The modular expansion joint from Yongxi has completed the design of expansion capacity of 80-2000mm, which can be used for all kinds of new bridges and for the
replacement of expansion joints of old bridges. Modular expansion joints consist of multiple parts to provide greater movement. Modular expansion device is designed
with the necessary movement capabilties and application areas in mind. These nodes may be displaced when single-span bridges are used, exceeding the bearing
capacity of the nodes.
