The DJK5-1 railway fastening system, as a high-performance elastic separated fastening solution, demonstrates outstanding advantages in railway track operations, providing strong support for track safety and stability.
Its clamping performance is highly reliable, utilizing standard railway spring clips available in two types: A and B. Type A offers a clamping force of 8 kN with 9 mm deflection, while Type B provides 9 kN clamping force with 8 mm deflection, catering to different installation requirements. Made of high-quality spring steel and subjected to specialized heat treatment, these clips ensure consistent clamping force, securely locking the rail in place to effectively prevent longitudinal and lateral displacement during train operation, thereby maintaining track structural integrity.
The system delivers excellent vibration damping, featuring 10 mm thick rubber pads installed beneath both the rail and baseplate. The elastic rubber material effectively absorbs vibrations and impacts generated by passing trains, reducing damage to the subgrade and sleepers, extending the service life of track components, while simultaneously enhancing ride smoothness and passenger comfort.
It offers flexible gauge adjustment with a range of +8 mm to -12 mm. By replacing gauge plates of different specifications, precise adjustments can be made to accommodate track geometry changes during both construction and operation, meeting maintenance requirements and ensuring accurate track alignment for safe train movement.
With superior insulation performance, the system's insulating components exhibit resistance exceeding 10⁸ Ω. This effectively blocks stray currents, preventing electrical leakage that could interfere with track circuits, avoiding electrochemical corrosion of rails and adjacent equipment, and ensuring proper signaling system operation to enhance overall track safety.
The connection strength is exceptionally robust, with embedded nylon sleeves providing over 60 kN of anti-uplift resistance. These components withstand various operational forces, maintaining secure fastening between components and sleepers without loosening. The tightening torque is optimized for different conditions: 80-120 N·m for standard sections and 120-150 N·m for sharp curves, further ensuring reliable system integrity to establish a solid foundation for long-term track stability.
