We would like to introduce the "E-0.5KN Vibration Generator" that we handle. It uses a method where the weight is moved by the rotation of a pole screw, and since the weight is directly connected to the motor, no noise is generated. Additionally, because it is a method of attaching weights, the main unit is lightweight (33kg), and it features a simple mechanism with fewer breakdowns. 【Features】 ■ Method of moving the weight by the rotation of the pole screw ■ No noise generated as the weight is directly connected to the motor ■ Lightweight main unit (33kg) due to the weight attachment method ■ Simple mechanism with fewer breakdowns ■ Can use AC100V power supply *For more details, please download the PDF or feel free to contact us.

• Structural Survey

The "IIS-T2000" is a specialized device developed in collaboration with the Tokyo Metropolitan Civil Engineering Technical Support and Human Resource Development Center for investigating the damage level of bridge RC slabs. This survey involves dropping a weight onto the center of the slab and measuring the free decay vibrations of the slab generated by the impact excitation, allowing us to understand the deflection, natural frequency, and damping constant. 【Features】 ■ Investigates the damage level of bridge RC slabs ■ Capable of removing the vibration components of the girder ■ Patent No. 2938810 Method for measuring deflection of slabs *For more details, please refer to the PDF document or feel free to contact us.

• Structural Survey

"Spider Eye" is a new inspection method for areas where bridge inspections are difficult. As one of the close visual inspection methods, it enables the assessment of damage conditions using a high-performance camera. We offer a "Standard Type" that excels in detecting cracks on the underside of the deck and a "Lifting Type" that is effective for assessing conditions in corner areas. It can be used in locations such as between main girders and cantilever sections where inspection paths are not installed. 【Features】 <Standard Type> ■ Assesses deformation conditions equivalent to the naked eye ■ Can distinguish damage and cracks wider than 0.2mm from captured images ■ Lateral removal through image synthesis is possible ■ The system is simple as the movement of the equipment is done manually *For more details, please refer to the PDF document or feel free to contact us.

• Structural Survey

In the "Ground Investigation Service," we can understand the vibration characteristics and health of the subject of investigation without damaging the measurement target. Our company not only handles measurement tasks but also provides comprehensive support in the field of ground and structure investigation, from formulating overall plans on what and how to measure to proposing data analysis. 【Investigation Achievements】 ■ Static load testing of bridges ■ Static load testing of Fukurai Bridge ■ Shaking table experiments for a three-story building ■ Traffic condition surveys (BWIM) ■ Shear wave velocity measurement for gravity dams, etc. *For more details, please feel free to contact us.
