Modern urban engineering calls for infrastructure that seamlessly integrates into the city layout. Tramways and light rail systems are the backbone of smart cities, providing clean, efficient transit. However, integrating rails into municipal roads introduces major engineering challenges. Tram Track Fastening Systems and Embedded Rail Systems (ERS) are designed to solve these issues.
Traditional ballasted tracks are loud, take up too much space, and cannot handle shared road traffic. Embedded Rail Systems encase the rail in a concrete slab using elastomeric materials. This creates a flat street surface, allowing trams, emergency vehicles, and pedestrians to share the same space safely.
A high-performance fastening system must do more than just hold the rail in place. It must act as a barrier against vibration, prevent electrical leaks (stray currents), and withstand heavy, continuous traffic.
Our fastening and encapsulation systems are engineered for diverse urban environments, ensuring durability and safety across multiple track configurations.
Integrated with turf or sedum coverings, our embedded systems allow green trackways to absorb rainwater, lower local temperatures, and blend into parks while keeping the rails secure.
Ensures a completely flush street profile. The elastomeric encapsulation prevents road cracking around the rail, making the surface safe for buses, cars, and cyclists.
High-insulation polyurethane materials block electrical leakage from DC traction systems, protecting nearby utility pipes and concrete reinforcement from corrosion.
The Changmei Testing Center conducts testing activities recognized under the International Laboratory Accreditation Cooperation (ILAC) and the Asia Pacific Accreditation Cooperation (APAC) through mutual recognition arrangements. This ensures that every tram track fastening system we produce meets strict international quality and safety standards.
