With its unique performance, the WJ-7 railway fastener system plays an indispensable role in a variety of railway construction scenarios and is a key component to ensure the safe and stable operation of railways.
Core application of ballastless track construction
The WJ-7 railway fastener system is designed for ballastless track without shoulder guards. It is the first choice for ballastless track construction on bridges, in tunnels, and in roadbed sleepers (double-block sleepers and long sleepers). In the laying of ballastless track on bridges, the impact force and vibration generated by train running are large. The good track elasticity and stable force performance of the WJ-7 system can effectively absorb vibration, disperse loads, avoid damage to the track structure due to frequent force, and ensure the long-term stability of bridge tracks. In tunnels, its excellent insulation performance can prevent the humid environment from affecting the track circuit and ensure the normal operation of the signal system.
Stability guarantee of high-speed railways
High-speed railways have extremely high requirements for track accuracy and stability, and the powerful adjustment ability of the WJ-7 system plays an important role here. Its height adjustment can reach 30mm, and the gauge adjustment is ±10mm. Whether it is the initial calibration during track laying or the later track deformation repair caused by factors such as settlement, it can accurately adjust the track geometry to ensure the safety and stability of the train when running at high speed. At the same time, the system's reliable performance verified by fatigue tests also meets the needs of high-frequency and large-volume operation of high-speed railways.
Adaptive application of special sections
In some sections with special requirements for track elasticity and vibration and noise reduction, such as railway lines near city centers or residential areas, the elastic design advantages of the WJ-7 system are significant. It can effectively reduce wheel-rail noise and reduce the impact of train operation on the surrounding environment. In addition, for small resistance sections, the WJ-7 system configuration with X2-type spring bars can be used to meet the track force requirements under special working conditions, showing good environmental adaptability and working condition adaptability.
