クリテック工業 Company Profile

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.

We would like to express our sincere gratitude for your continued support. As you may be aware from recent news reports, the situation in the Middle East has deteriorated rapidly, leading to an increase in the prices of raw materials originating from that region. Consequently, there is a possibility that the prices of our products may also rise in the future. Please be advised that due to fluctuations in the market conditions of raw materials, we may change prices without prior notice, and we appreciate your understanding in advance. Additionally, regarding product delivery times, we are currently operating as usual. Should there be any changes in the future due to the situation, we will inform you accordingly. We apologize for any inconvenience this may cause and thank you for your understanding.

The main shock of the Kumamoto earthquake that occurred in the early hours of April 16, 2016, caused the Aso Ohashi Bridge to collapse, significantly impacting local transportation. Following recovery efforts, the New Aso Ohashi Bridge was opened in 2021. In the New Aso Ohashi Bridge, structures that can accommodate future fault displacements have been incorporated, such as the use of a steel simple box girder bridge over the fault. Additionally, the expansion joints installed at the bridge's seams are designed to follow fault displacements. Our bridge expansion joint, the "Hybrid Joint LL Type," has been adopted for this New Aso Ohashi Bridge, contributing to the safety and functionality of the bridge while accommodating large displacements. Japan is a country prone to earthquakes, and bridge design requires ensuring safety against Level 1 seismic motion (earthquakes occurring during the service period) and Level 2 seismic motion (maximum class earthquakes). Moving forward, our company will continue to provide technologies that support the safety and security of social infrastructure.
