Rubber Rail Pad
Rail pad, is a rail rubber plate between the rail tie plate and foot of the rail, made of elastic polyurethane, which is interposed between steel rails and sleepers to reduce friction and impact. Rail pads are fastened within a fastening system by screw spikes or rail bolts into the sleeper ties. It is designed to increase the elasticity of the superstructure, reduce shock and vibration in the rail system. Rail pad is made up of rubber or plastic is to dampen the shocks and vibration effecting on the train and track. Usually starting with setting a low stiffness in order to make spring clip has a larger relative deformation, which can guarantees the rail pad maintaining in close contact with the rail, make the rail pad play a better role.
AGICO equips 130sets machines' rail pad production line, for processing, injection, refining rubber, sulfuration , moulding and inspection etc. We have our own rail pad development engineers, designing, producing and inspecting, our annual production capacity reaching up to 2000, 000 pieces. What’s more, rail pads for high-peed rail are our featured products, including both the elastic rubber plates and height adjustment pads.
