The service life of railway fishplates

When the train passes through the railway, the wheels will exert extreme pressure on the track, rail and fishplate. Axle overload can lead to fracture and wear of rail and fishplate, thus affecting their service life.

in cold weather, the rail may appear cold cracking phenomenon, resulting in the fracture of the rail; In hot weather, the rail and fishplate may be distorted and deformed due to temperature changes, which will affect their service life.

rail and fishplate in the process of use, due to constant pressure and friction, will gradually produce stress. If these stresses are too large, it will lead to the fracture of the rail and fishplate.

The quality of railway fish board directly affects its service life. High quality materials have better wear resistance, corrosion resistance and fatigue resistance, which can extend the service life of railway fish boards.
