Over 20 years of domestic experience in measuring the deflection of steel bridges using laser distance sensors.
By using a laser distance sensor to measure the deflection of the iron bridge, the health of the shoe (bearing) can be determined.
Features - A system that dynamically measures instantaneous values during vehicle operation, as well as the deflection of railway bridges and heavily trafficked bridge girders. - High responsiveness (up to 250Hz) allows for precise monitoring of the movements of steel bridges (sinking, rebounding, and oscillating) during vehicle passage. - Installed directly underneath or diagonally below the girder, it continuously measures the distance to the girder during vehicle passage to calculate the deflection amount. - The use of easy-to-install, non-contact laser distance meters eliminates the need for extensive preparations or traffic regulations, which is a significant advantage. - In cases where the target object is black and sufficient reflected light cannot be obtained, reflective stickers or similar materials can be utilized. - Proven track record of use for both long-term and short-term applications on steel bridges, concrete bridges, roads, and railways. - If the displacement exceeds the management value, a rotating light provides a real-time alarm, allowing for decisions such as temporary work suspension. Our company also offers comprehensive support for usage methods, installation, control software development, and technical assistance.

Company information
Since its establishment, we have been involved in the development of our own products, starting from gathering ideas, and have repeated the processes of mechanical design, processing, circuit design, and embedded programming every year. Currently, we are engaged in both OEM production and the sale of our own products, and we intend to continue developing measuring instruments that can further meet our customers' needs. We are also the general agent for Dimetix in Switzerland and are focusing on the sales of red laser distance meters. This product has been adopted for measuring the height of the Tokyo Skytree, the tallest structure in the world. We believe there are still many applications for this technology, and we would like to explore each one. In recent years, we have also been focusing on measuring instruments for railway-related construction limits. We have started to receive inquiries from East Japan Railway Company regarding the development of measuring instruments for construction limits in various fields such as construction, civil engineering, signaling, and power. Additionally, we received an Encouragement Award at the 28th Ota City Small and Medium Enterprises New Products and New Technologies Competition for our graphic-integrated construction limit measuring instrument.
