The Functions of Rail pad in Railway Track

The raid pad prevents rail-sleeper abrasion and the crushing of the sleeper under the rail foot. Rubber rail pads are normally designed to a specified load-deflection characteristic. The initial stiffness of the rail pad is designed to be low so that that their deformations under the springs toe loads is quite substantial. This ensures that the rail pad remains in intimate contact with the rail despite any vertical movements of the latter. When the wheel is over the pad, the latter's stiffness must be high to prevent large movements which can result in the metal spring becoming loose. Such a load-deflection characteristic can be obtained by introducing grooves in the rubber rail pads.

GNEE RAIL provides exceptional elastic rail pads (grooved railway pads ,Studded rail pads)of various types for high-speed railways, normal-speed railways, and cranes. Especially the rail pads made of rubber, EVA, TPEE, and HDPE. Our railway rubber pads fit the rails such as UIC54, UIC60, BS80lbs, BS100lbs, etc.

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
