What is the Tensile Strength of the Rail Pad

Rail Pad is an important component in railway and crane rail systems used to alleviate vibration, reduce noise, and protect the track structure. Its tensile strength is a key indicator measuring its load-bearing capacity and durability.

Rail pad functions

 

A rail rubber pad is essential in reducing shock and vibration in a rail system. The pad laid under the rail to ensure:

 

• Load distribution over a larger surface

 

• Elimination of load concentration and the resultant fatigue stresses

 

• Centering of loads on the supporting element

 

• Absorption of uneven contact surfaces between rail and support

 

• Reduction of noise and vibration

 

• Sealing between the bottom of the rail and the top of the support

 

• Reduction of wear of the rail and its support
