The role and importance of rail clips

Rails are fixed to the ballast or sleepers by elastic fasteners. The buckling parts of elastic fasteners are mainly rail clips, which generate buckling pressure on the track through bending and twisting deformation of the rail clips, effectively ensuring the reliable connection between the rails for a long time, maintaining the integrity of the track as much as possible, preventing the longitudinal and lateral movement of the rails relative to the sleepers, ensuring the normal track gauge, and thus ensuring the safety of rail vehicles. In addition, since the contact between the train wheels and the rails is rigid contact, vibration is inevitable, and the special elastic structure of the rail clips enables them to absorb the impact energy generated by the passing of vehicles, achieving the effect of shock absorption.

We can also manufacture customized rail clips following your drawings or samples!

The rail clips work under repeated alternating stress, and they are subjected to bending, torsion, fatigue and corrosion. When the vehicle passes, they also have to withstand extremely high instantaneous impact loads, so the performance requirements of the spring bars are very strict.

rail clips application

rail clips structure

The role of rail clips in railway turnouts cannot be denied, and they also provide protection for the safe operation of railway turnouts. However, rail clips also have a certain lifespan, and when using rail clips, in order to reduce the failure rate and extend the service life, maintenance and repair work must be done well during the application of rail clips.
