[Published in the January 1, 2026 issue of Bridge News] "Hybrid Joint Type 3LII" adopted for Meishin Concentrated Construction! Introduced as an advanced example of large finger joint replacement.

A newly constructed bridge requires no replacement for 100 years! Long-term water resistance, maintenance-free.

In the longevity of bridges, the durability of expansion joints is a very important factor. Replacing expansion joints requires significant costs and traffic regulations, which can reduce the operational efficiency of bridges. The Hybrid Joint Type 3LII achieves a durability of 100 years, contributing to cost reduction and improved safety from a long-term perspective. 【Application Scenarios】 - New bridges - Repairs of existing bridges - Highways * For general roads, there is the "Hybrid Joint Type 3LIIA." 【Benefits of Implementation】 - Reduction in lifecycle costs due to no need for replacement for 100 years - Maintenance-free, eliminating the need for sound inspections and ultrasonic inspections, reducing maintenance costs - Decreased frequency of traffic regulations, mitigating traffic congestion and noise damage, and enhancing safety - Adoption of new technology through NETIS registration (No. KT-210067-A)

The "HA-T Series" is an energy-saving automatic door sensor that opens only for those who want to enter, whether on a busy street or in a narrow passageway. The automatic door opens simply by bringing your hand close, addressing hygiene concerns even in facilities used by a large number of people. Depending on the application and installation location, you can choose between "Non-vision Mount Type/HA-T401" and "Non-vision Built-in Type/HA-T520." 【Recommended for such places!】 ☑ Entrance facing a busy passageway ☑ Presence of counters or signs near the door ☑ Buildings facing narrow passageways ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors 【Features】 ● Adaptable to various door types with four detection spot settings ● Reduces unnecessary opening and closing to minimize power consumption, contributing to energy-saving effects ● Equipped with a light touch function, allowing the door to open and close simply by waving your hand, ensuring hygiene ● Can also be used as a wide detection range non-vision infrared sensor ◎ For more details, please download the materials or contact us.

Dakota Japan Co., Ltd., which specializes in the sale of ultrasonic testing equipment such as ultrasonic thickness gauges, flaw detectors, and axial force gauges, will begin selling its new product, the A-scan ultrasonic thickness gauge 'CMX10-DL', starting June 15. The 'CMX10-DL' is a versatile A-scan ultrasonic thickness gauge that caters to a wide range of applications, from corrosion inspection to high-precision thickness measurement. It supports the measurement of remaining wall thickness in tanks and pipes, substrate thickness measurement over coatings, as well as the measurement of lining materials, composite materials, and clad materials, including precision thickness measurements requiring a resolution of 0.001mm. The CMX10-DL not only saves echo waveforms and measurement values but also supports echo recording for up to 10 seconds. This allows for the recording of instantaneous thickness changes or waveform changes during measurement, thereby streamlining the verification of inspection results and report generation. Additionally, with TCG (Time Corrected Gain), BEA (Bottom Echo Monitoring), and B-scope (B-scan), it supports reliable measurements even for challenging targets such as composite materials, clad materials, and localized corrosion, where waveform judgment can be difficult.

Dakota Japan Co., Ltd., which specializes in the sale of ultrasonic testing equipment and hardness testers, has launched two new models of rebound hardness testers, "Leeb Lite" and "Lab Leeb," starting May 20. The "Leeb Lite" and "Lab Leeb" are rebound hardness testers suitable for measuring the hardness of metallic materials with a mass of over 5 kg and a thickness of over 25 mm. They are lightweight, compact, and easy to operate, making them user-friendly for those conducting hardness measurements for the first time, and they enable stable measurements in the field. The rebound (Leeb) method is suitable for measuring the hardness of large components and can be applied to a wide range of targets, including cast and forged products, welds, machined parts, and heat-treated items. Additionally, the "Lab Leeb" supports Bluetooth communication, allowing it to connect to smartphones and tablets for use. With the dedicated app "NOVOTEST Lab," users can view measurement values on a large screen, and data sharing of reports, photos, and videos can be done smoothly.

Palmholtz, which is working on the development of new materials utilizing discarded oil palm trunks (OPT), will establish a system for increased production of the new materials starting in May. The technology for developing the new materials recently received the "Monozukuri Nippon Grand Award Chubu Bureau of Economy, Trade and Industry Director's Award." Taking this opportunity, inquiries have been received from major global e-commerce (EC) companies, accelerating the movement towards commercialization. The company will also respond to demands for increased supply from existing customers.
