Technical Parameters
Core functions
- Fix rails: cooperate with sleepers (such as concrete sleepers or wooden sleepers) to ensure the stability of rails.
- Provide elasticity: absorb vibration and impact during train operation through elastic deformation.
- Anti-loosening: special structural design (such as double-ear or single-limb locking) prevents bolts from loosening.
