Short-term measurement of ground anchor tension using the 'VIBRES System'
Calculate from the physical formula! By using vibrations to measure the tension of ground anchors, we can improve work efficiency and safety. [Comprehensive catalog available]
The "VIBRES System" is a technology that uses a small device to efficiently measure the tension of ground anchors in a short period of time. By applying a "sweep vibration" that gradually increases in frequency over time using a small vibrator attached to the anchor's excess length, it excites the resonance of the tendon free length. By using vibration to measure the tension of ground anchors, this innovative technology achieves improved work efficiency and safety. 【Features】 ■ Efficiently measures the tension of ground anchors in a short time ■ Excites the resonance of the tendon free length ■ Achieves improved work efficiency and safety A comprehensive catalog featuring products from the NEXCO Central Japan Group is now available! It has been renewed in October and is the latest version of the comprehensive catalog. *For more details, please refer to the PDF or feel free to contact us.
