Characteristics of Rail Metal Clips Fasteners
Sep 22, 2017

According to the requirements of rail transit, the new type of Rail Metal Clips Fasteners should have the following characteristics:

1) there is sufficient strength and durability

The rail transit operation time is long, the traffic density is high, the maintenance condition is poor, and the steel Rail Metal Clips Fasteners must have enough strength and durability to ensure the driving safety.

2) there are certain gauge and horizontal adjustment performance

The rail transit USES the overall structure of the bed, the radius of the line curve is small and the rail is worn.

This requires that the fastener should have a certain track distance and horizontal adjustment performance to solve the problem of uneven settlement and construction errors caused by the uneven settlement and construction errors of the curved steel rail and the construction errors.

3) good insulation performance

Rail transit are commonly used line tracks as reflux rail, which requires the fasteners must have good insulation property, prevent current leakage through the fasteners, cause structural steel and municipal pipeline corrosion.

4) there is good elasticity of vibration

Subway and other urban rail transit transit through the residential area, the environmental protection requirements of vibration reduction and noise reduction are very high, the rail fastener must have good vibration damping performance, attenuation track vibration, and reduce the noise transmission.

5) there is a certain general interchangeability

The structure of the fastener should be simple, the parts are few, have certain general interchangeability, the cost is low, construction and maintenance is convenient.
