Rail pads are placed between rails and sleepers to protect the tops of the sleepers from wear and impact. The rail pads are kept in close contact with the rails. Generally, the rail pads are made of rubber or plastic insulators, which act as a buffer to suppress the impact of passing train vibrations on the wear of rails and sleepers.
Rail pads are critical to reducing shock and vibration in the rail system, so materials must be wear-resistant.
The rail pads are placed under the rails to share the load on a larger surface, eliminating load concentration and resulting fatigue stresses.
It can absorb the vibration and noise caused by uneven contact surfaces between rails and sleepers
We can provide rail pads for E-type rail fixing system . SKL type rail fixing system and fist rail fixing system , respectively, with the following properties.
Polyethylene 80%, Vinyl Acetate 20%.
Hardness Shore A
Tensile Strength before Aging
Elongation before Aging
1、Rail pad used for E type rail fastening system
Rail pads used for E-type rail fastening systems are functionally similar to rail insulators used to isolate rails and sleepers to effectively prevent vibration and solid noise. Rail rad is used with Elastic clip , rail insulator. .rail shoulder to well fix the rails .
2、Rail pad used for SKL rail fastening system
Rail pad in a SKL rail fastening system Used with SKL clip, screw spikes, rail insulators, plastic dowels, etc. We produce rail pads with definite stiffness and increase the elasticity of the rail's superstructure. With this flexibility, it helps to achieve the quiet operation of railway vehicles to meet the requirements of today's railway operations.
3、Rail pad in fist rail fastenng system
Rail pad in fist rail fixing system , which is used together with fist clip .insulation pin , it is widely used in African countries.
