We would like to introduce our company's "Vibration Mitigation Measures for Railway Tracks." The importance of railways with excellent eco-performance as a solution to 21st-century transportation issues is increasing. However, various types of railways, including linear railways, cannot ignore the vibrations transmitted to the surrounding areas. Our "Gelb Floating Slab Track System" significantly reduces the vibrations propagated to the surroundings during train operation and effectively functions as a solid sound mitigation measure. [Features] - The natural frequency of the vibration mitigation device can be designed to approximately 4 to 8 Hz. - The vibration mitigation device can be embedded within the slab. - Installation and replacement of the spring unit can be performed from above the track slab. - High horizontal rigidity allows for minimal lateral deformation during train operation and small to medium earthquakes. - Durable coil springs and viscous dampers are maintenance-free. *For more details, please refer to the PDF materials or feel free to contact us.

This document provides a detailed explanation of "railway track vibration control." It includes solutions such as "gel-based solutions for controlling solid-borne sound and vibrations," as well as "solutions using metal coil spring devices" and "solutions using NOVODAMP closed-cell polyurethane." Additionally, it presents examples of achievements along with images, making it a useful reference.

Our company conducts installation and adjustment work for viscous dampers and spring elements, as well as installation supervision work and measurement and analysis of vibrations and solid sounds generated by machinery and equipment. We provide economical vibration isolation foundations that meet customer requirements for various types of equipment. The technology for reducing vibrations has been researched and refined at Gelb for many years to ensure the safety and reliability of machinery. If you are troubled by even very small vibrations or noise in your surroundings, Gelb is here to support you. 【Areas of Activity (Partial)】 ■ Installation and adjustment work for viscous dampers and spring elements, as well as installation supervision work ■ Measurement and analysis of vibrations and solid sounds generated by machinery and equipment ■ Engineering from the provision of fabrication drawings for both reinforced structures and reinforced concrete structures to construction supervision ■ Foundation design for machinery and equipment or building structures, considering cost-effectiveness based on customer specifications *For more details, please download the PDF or feel free to contact us.

Buildings adjacent to railways, such as hotels and music facilities, need to reduce the impact of vibrations and solid-borne noise generated during train operations, as they are integrated structures with railway facilities. Coil springs provide a higher vibration isolation effect than anti-vibration rubber. By using floating track slab technology, it is possible to reduce vibrations transmitted from the track to the building by one-tenth (-20dB to -30dB). We propose construction methods tailored to the type of track and site conditions. 【Advantages of the Gelb Method】 ■ Reduced number of installations due to high load-bearing coil springs ■ No need for stoppers due to horizontal rigidity ■ High corrosion resistance allows for outdoor application ■ Embedded slab design reduces installation height ■ Easy height adjustment with shims *For more details, please download the PDF or feel free to contact us.
