Description

Rail elastic clip is used to fasten the rails to the underlying base plate together with the concrete sleeper. Usually rail clips are made of forged spring steel which is produced by hot forging process. Because of the uniform microstructure of forged clips, it is considered to be better than other metal forming process.

Production Processes of Elastic Rail Clips:

1. Raw material purchasing
2. Shearing
3. Heating to forging temperature
4. Forming
5. Hardening
6. Tempering
7. Surface treatment
8. Inspection-Packing

Russian Rail Clip

The Moscow State University of Railway Engineering (MIIT) has developed APC bolt-free anchor rail fastening system , which can work on main lines at any speed and load load. Its positive qualities are high reliability and ensuring the stability of the track width, low detail and low material consumption (saving metal at least 15 tons per 1 km), ease of assembly. The fastening is inseparable, the main element of the fastening is a frame-arch type anchor embedded in a reinforced concrete sleeper.

The design includes two flat polymer sub-clips, two on-rail insulating corners, two under-rail elastic gaskets with a thickness of 14 mm. The fastening of the modifications of the APC-4 allows you to adjust the position of the rail in height up to 20-24 mm.
