Expansion Device Hybrid Joint [Construction Example, Wakayama 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 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 joints that are removed. 【Construction Example】 ○ Location: Wakayama Prefecture ○ Bridge Name: Takasegawa Bridge ○ Product: 3L-400 ○ Comment: Due to the heavy weight of the product and the windy conditions at the high-altitude site, we exercised utmost caution when lifting with a crane from below the girder and during installation. For more details, please contact us or request a catalog.
