Rail accessories is a series of professional parts

Spikes and screws A. Rail spike A rail spike (also called as a cut spike or crampon) is a nail with an offset head that is used to secure rails and base plates to railroad ties in the track. Common sizes are from 9 to 10/16 inch square and ~5.5 to 6 inch long. And its main function is to keep the rails meter. Additional connecting plate attachments to be as strong as possible, and when connected to the rail, tie or tie plate is generally not required to provide a strong vertical force, allowing the railway more freedom of movement. B. Screw spikes A screw spike, rail screw is a large metal screws used to the fixed tie plate or fixed rail. The screw spike ixed into a hole in the sleeper. The screw spike having a higher manufacturing costs than the spike, but the advantage of having a larger fixing power, approximately twice the spike, and can be combined with the spring washer. C. Fang bolts Fang bolts have also been used for fixing rails or chairs to sleepers. For fastening flat bottom rail the upper lip gasket may be used to grip the edge of the guide rail. They are more resistant to vibration loosening and moving rails. They are considered to be the more effective than spikes and screws, and so are used in positions such as switch (point) tie plates, and on sharp curves. 2. Rail supports a. Chairs Earliest railway chairs, made of cast iron, about 1800 to launch fixed at both ends for the cast iron rails and support, they can also be used to connect adjacent tracks. Chairs have been fixed to the sleeper using wooden spikes, screws, fang-bolts or spikes. b. Tie plates Tie plate, base plate or a sole plate with steel plate flange the T track and sleepers on the tracks. The increase in the tie plate bearing areas and to have railway corrective count. They spikes or bolts through the holes of the plate fixed to the wooden relationship. 3. Clips There are a variety of different types of heavy clip using the rail is fixed to the underlying substrate, a common the Pandrol Pandrol clip. 4. Rail Rail per meter approximate weight in kilograms, can be divided into two kinds of heavy rail and light rail. The manufacture and use. Rail open hearth furnace, oxygen smelting carbon killed steel rolling. Its purpose is to withstand the operating pressure of the rolling stock and the impact load. Manufacturing plant and importing countries. Rail currently used in China, some domestic steel production, such as Anshan Iron and Steel, Wuhan Iron and Steel. In addition, due to the larger amount needed to import some of the physical and chemical properties required by our technical standards and relevant foreign standard method to determine the rail and rail attachments. The imported production are Japan, Germany, France, Britain, Russia, Australia and other. Future development Railway accessories industry investment in the development of the next 10 years, will maintain a relatively high level. In the context of the rapid development of the railway system in Jiangxi, this trend, the domestic production of railway accessories will be a key process. With the process of high-speed railway construction, railway parts industry in China will achieve greater development.
