Expansion Device Hybrid Joint [Construction Example Aomori Prefecture]
We would like to introduce a case study of the hybrid joint (Type 3L), a bridge expansion device that excels in water resistance and durability.
Crittec Industrial Co., Ltd. not only sells products but often takes full responsibility for installation work as well. We strive to improve our products by considering the issues that arise during installation and the damage conditions of the removed existing expansion devices. 【Construction Example】 - Location: Aomori Prefecture - Bridge Name: Nozomi Bridge - Product: 3L-250 - Comment: Since vehicles could not access the bridge, we performed the installation by lifting it with a crane from underneath the bridge. For more details, please contact us or request a catalog.
