Expansion Device Hybrid Joint [Construction Example Ehime Prefecture]
We would like to introduce a case study of the hybrid joint (3L type) for bridge expansion devices, which excels in water resistance and durability.
Crittec Co., Ltd. not only sells products but often takes responsibility for installation work as well. We strive to improve our products by considering issues that arise during installation and the condition of existing expansion devices that have been removed. 【Construction Case】 - Location: Ehime Prefecture - Bridge Name: Oshima Bridge - Product: 3L-300 - Comment: Since work had to stop when boats passed under the bridge, we conducted the installation with a supervisor present. It was impressive to see many cyclists stopping on the bridge to take photos of the scenery visible from there. For more details, please contact us or request a catalog.
