The railway fastener manufacturers tell you that there are many types of clips, such as type I clips, type II clips, type III clips, etc. Different types of clips have different characteristics and can be applied to different tracks. Therefore, when purchasing, the user needs to choose the appropriate elastic strip according to the model of the turnout.

Except for the redesign of the spring bar with new materials, the other parts of the spring bar type II fastener are the same as the spring bar type I fastener, which is still a shoulder and bolt fastener. In the area of ​​the original type I fastener, the original type I fastener can be replaced by the type II fastener. The buckle pressure of a single elastic strip is not less than 10KN, and the elastic range (that is, the amount of elastic deformation) is not less than 10mm, which is about 30% higher than that of the I-type fasteners. After the assembled fasteners are subjected to 2 million cycles of lateral fatigue load, each part shall not be damaged. The railway fastener manufacturer tells you that in order to improve the strength and buckle pressure of the elastic strip, the spring steel 60SiCrVA is selected as the material of the type II elastic strip, and the yield strength and tensile strength are increased by 42% and 36% respectively. On the basis of the optimal design of the elastic strip, the diameter of the elastic strip is determined to remain unchanged, which is the same as the type I fastener, which is still 13mm. The elastic type II fastener has the advantages of high buckle pressure, large strength safety reserve, and small residual deformation.
Type III spring clips are boltless and shoulderless fasteners. Railway fastener manufacturers tell you that bolt-free and shoulder-free fasteners are the development trend of sleeper fasteners in various countries, especially suitable for heavy-duty, large-volume, and high-density transportation conditions. The spring bar type III fastener uses the cast shoulder embedded in the concrete sleeper to maintain the gauge and bear the lateral force. The railway fastener manufacturer tells you that the elastic strip III type fastener has the advantages of high buckle pressure and good elasticity, especially the removal of the concrete sleeper shoulder, thereby avoiding the possibility of the rail gauge expanding due to the lateral movement of the rail bottom under the action of lateral force. , so the ability to maintain the gauge is very strong, and because of the cancellation of the bolt connection, the maintenance workload of the fastener is reduced.
