Whether it is a spring fastener or a rail fastener,it is a part on the track.Due to a long time with a variety of railway accessories contact,so for a variety of accessories also have a certain understanding. 1.Spring Clip has sufficient strength and durability.Due to the long operation time,high driving density and poor maintenance conditions of rail transit,the rail fastener must have sufficient strength and durability to ensure driving safety. 2.It has a certain gauge and horizontal adjustment performance,rail transit mostly adopts the overall track bed structure,line curve radius is small,there is wear rail.This requires that the fastener should have a certain gauge,horizontal adjustment performance,in order to solve the curve rail wear and uneven settlement of the structure and construction errors caused by the gauge,rail horizontal overlimit. 3.Good insulation performance.Rail transit generally uses the running rail as the backflow rail,which requires that the coupler must have good insulation performance to prevent the leakage of current through the coupler and cause the electrical corrosion of structural steel bars and municipal pipelines. 4.Spring Clip has good vibration reduction elasticity.Metro and other urban rail transit travel through residential areas,which requires high vibration reduction and noise reduction. 5.It has a certain general interchangeability,the fastener structure should be simple,few parts,has a certain general interchangeability,low cost,construction and maintenance is convenient. The introduction of the performance characteristics of the rail fastener is here first.I hope you can understand the rail fastener more through this information.
