Tunnel cross-section / Construction limit measuring device 'LDM300A' *Short-term rental available
Improving the reliability of inspections and construction as an alternative to measuring with a tape measure! Easy measurement of guaranteed result data. Numerous achievements in home structures, signals, tunnels, and overhead lines.
The "LDM300A" is a tunnel cross-section/building clearance measuring device capable of limit measurements with a high precision of only ±3mm. The base is installed on the rail, and a laser is projected onto the measurement point. The horizontal distance from the rail surface and the track center, as well as the height, are measured. At the same time, the measurement points are drawn on the building clearance diagram, and the separation values are calculated. 【Features】 ■ Equipped with a color graphic LCD (allows confirmation of measurement results on-site) ■ Equipped with an inclination sensor (can measure cant with a dedicated base) ■ Compact and labor-saving (has a widening measurement function) *Short-term rentals (from 1 day) are also available. If you wish to rent, please contact us via the inquiry form and indicate "Rental Request."

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.
