Rail clip, or called elastic rail clip, is used to fasten steel rails to the underlying tie plate. Through bending and distortion, rail clip can put pressure on the rail, which prevents longitudinal movement of the rail, either from changes in temperature or through vibration. In general, rail clips are made of forged spring steel produced by hot forging process.
During the use of railway elastic clips, many issues often arise in installation, application, and maintenance. Below are four common problems encountered by clients as summarized by GNEE RAIL:
What are the consequences of incorrect installation of elastic clips?
Incorrect installation may shorten service life and cause deformation. Therefore, during installation, ensure the clip maintains a clearance of approximately 10 mm from the embedded iron tower.
How to address corrosion of metal elastic clips?
First, understand conditions that may increase the torque of rail screws. During retrofitting and installation, avoid repeated disassembly. Regularly apply oil and paint to corroded areas.
What if the gap between gauge steel and gauge block exceeds 1 mm?
This may affect track gauge, threatening train safety. Immediately replace with an appropriate gauge block.
How to resolve a gap exceeding 0.5 mm between the central front claw of the clip and the rail insulator?
When the gap exceeds 0.5 mm, the clip's torque and pressing force are significantly reduced. Ensure installation maintains a gap smaller than 0.5 mm.
