クリテック工業本社、大阪営業所

The bridge expansion device manufacturer, Crittec Co., Ltd., is seeking a few ambassadors for the "100-Year Bridge Project," who are interested in the civil engineering and bridge fields and can share their appeal and social issues through social media. This initiative aims to raise awareness about the current state of aging social infrastructure and the importance of maintenance and management. We welcome individuals with interest or knowledge in civil engineering and bridges as ambassadors to collaboratively plan, create, and disseminate content, thereby promoting understanding and revitalization of social infrastructure as a whole. Would you like to share the interesting aspects and importance of social infrastructure through your perspective and creative activities? We welcome those who are engaged in creative activities or information dissemination related to civil engineering and social infrastructure, as well as those who wish to take on new challenges. The number of followers does not matter. Your "likes" and "messages" may connect to the future of social infrastructure. Please feel free to apply.

Durability 100 years, expansion device, hybrid joint, type 3LII.
A bridge expansion device proven to last 100 years! No replacement needed for new bridges for 100 years! Long-term water-tightness, maintenance-free [NEXCO specification compliant product].

**Features** 1) Ultra-long durability of 100 years: Achieved 12 million cycles in fatigue loading tests by a third-party organization, proving a durability of 100 years. 2) Long-term water-tightness of 50 years: Proven water-tightness equivalent to 50 years through water-tightness performance tests by a third-party organization. Secondary water-stop materials are standard specifications. 3) Large expansion and contraction capacity and wide gap compatibility: One of the largest expansion capacities among NEXCO-approved products. Capable of accommodating expansion from 150mm to 350mm and maximum gap of 730mm. 4) Ultra-low noise and vibration-free: A vertical integrated structure with 32mm thick steel plates arranged vertically and alternately, making it difficult for air vibrations to transmit under the beams, thus reducing noise. Smooth and comfortable driving experience. Small wheel load support intervals make it less likely for impact vibrations to occur during driving. 5) Easy to install: Can be constructed without road closures, using lane restrictions that allow shared use of one side for both new installations and repairs. Lighter compared to conventional large products. 6) Maintenance-free: The load support plate and anchor plate have a vertical integrated structure with high durability. Additionally, the structure prevents damage from metal fatigue, allowing for visual maintenance management. Visual inspections are sufficient, eliminating the need for regulated sound inspections. 7) NETIS registered: This is a new technology registered in the Ministry of Land, Infrastructure, Transport and Tourism's database system "NETIS." Registration No. KT-210067-A.
