The DJK5-1 railway fastening system, with its unique performance advantages, has well-defined and extensive application areas in railway track engineering, primarily focusing on specific scenarios such as urban rail transit and railway yards.
In 50kg/m rail yards, this system plays a vital role. It is widely used in maintenance depots, parking inspection bays, and train washing lines. These areas feature low train speeds (typically ≤15km/h) but frequent starts and stops, demanding high longitudinal impact resistance from fasteners. The DJK5-1 system's spring clips provide stable clamping force to securely fasten rails, while its embedded sleeves with over 60kN anti-uplift resistance effectively withstand frequent operational forces, ensuring track structure stability.
The ground sections of access lines represent another core application. Connecting main subway lines with depots, these ground sections often use ballasted tracks with relatively lower foundation precision. The system's ±12mm gauge adjustment capability allows quick adaptation to track deviations through interchangeable gauge plates, while its rubber pads' elasticity buffers vibrations during train movements, minimizing impact on ground foundations and adapting to complex operational environments.
The system is equally indispensable for ballasted test tracks. As testing grounds for newly manufactured or maintained trains requiring various operational condition trials, these tracks demand exceptional stability and safety. The DJK5-1 system's insulation components with resistance exceeding 10⁸Ω prevent stray current interference with track circuits, ensuring signaling system accuracy during tests, while its superior damping capacity handles vibration impacts at different testing speeds.
Furthermore, the system meets requirements in branch lines and light rail yards where specific demands exist for track elasticity, insulation, and adjustability, providing reliable operational safety for these areas.
