grooved rubber sole plate
GNEE RAILWAY RAILWAY is an approved supplier of grooved rubber sole plates, commonly known as GRSP rail rubber pad. We are the suppliers to the Indian Railways and also have been a part of other railway projects across the country. We are dedicated to exporting our products outside India as well. The rail pads are a combination of grooved designs and premium quality selected rubbers. This combination makes it highly resilient with anti-weathering properties and increased robustness for railways. The materials used to manufacture rubber pads for railway tracks have proven to be a dynamic force by up to 65%. It has allowed the railways to adopt a higher speed and greater axle loads than before. The grooved rail pads are fit between the rail underside and the sleeper top.
Functionality of Railway Track Rubber Pads
The rail rubber pad in the railways plays a crucial role in acting as a vibration-damping isolator between the cast surface of the concrete sleeper and the railway track. The vibrations that have been by trains must not be ignored in the field of engineering. Therefore, these methods have been adopted to efficiently eliminate the same. The rubber rail pads play a crucial role in eliminating the vibrations and reducing the impactful load occurring from heavy-weighted railway wagons. It enhances safety and lifespan of the railway tracks and sleepers.
GNEE RAILWAY RAILWAY'S rail pad process of compounding is optimized using a combination of polymers that have high oil-resistant properties and resistance to fatigue crack growth. The combination of elastomers is preferred in this formulation which helps in providing resistance to ozone, heat, flame, weather, and higher axle load.
The use of railway rubber pads can greatly improve transportation capacity of rail vehicles and reduce the times of maintenance for railway crossing to avoid flameout traffic accident caused by them. For both economic and environmental benefits and other aspects of social security, rubber pads are worth popularizing (concrete crossing plate is easy to be damaged with much noise).
GNEE RAILWAY RAILWAY have developed a range of high-performance elastic rail pads for stiffness requirements and various application areas-from trams through standard gauge railways to heavy haul lines, especially those for E-type rail fastening systems and SKL type rail fastening systems with material of HDPE/EVA/Rubber, with following properties respectively.
