What is Steel Track and the Classification of Chinese Steel Track?

图片
Steel Track  is  the main components of railway track. Its function is to guide the wheels of the rolling stock to advance, to withstand the tremendous pressure of the wheels  and to pass to the sleepers. Steel tracks must provide a continuous, smooth and resistant rolling surface for the wheel. In an electrified railway or automatic occlusion section, steel track can also serve as a track circuit. The classification of Steel Track: China's steel tracks can be divided into  Crane Rail ,  Heavy Steel Rail  and  Light Steel Rail . 1.  Crane Rail The crane rail is divided into four types: QU120, QU100, QU80, QU70. The material is generally manganese steel. The single weight is QU120 up to 118kg/m. 2.  Heavy Steel Rail According to the steel grades used: ordinary manganese-containing rails, copper-containing carbon steel rails, high-silicon copper-containing steel rails, copper rails, manganese rai...

What Is Studded Rail Pads?

图片
Today we  Railway Accessories  manufacturer come to summarize the What Is Studded Rail Pads. Manufactured in a variety of natural & synthetic elastomers, studded Rail Pads are designed to withstand the most demanding operating environments. Studded Rail Pads  are the first choice of rail systems worldwide as they adopt higher speeds and increased standards of passenger comfort and safety. Studded rail pads can provide excellent impact attenuation, noise suppression, improved passenger comfort, and extended track and ballast life.

Rail Pads

Here is  China Welding Clamp Factory  talking about Rail Pads. If you have any idea about it, welcome to contact us and discuss. Rail Pads  can prevent 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 are 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 rail pad 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. A rubber pad or grooved rubber rail pad are made up of rubber or plastic to dampen the shocks of vibrations of a passing train. Next, I will show you more...

Advantages Of Rail Tie Plates

图片
Tie Plate  distributes the load from the rail to the ties and provide a uniform bearing surface for the rail and prevent rail movement. Rail tie plates provide proper cant and obtain central loading and more uniform wear on the railhead. Tie Plate For Rails  hold the rail rigidly to gauge and protect ties against undue wear, which prolongs the service life. Rail tie plates are fabricated from heavy hot-rolled steel sections which are punched and sheared to size.

Functions Of Rail Tie Plates

As a  Railway Tie Plate Manufacturer , we will discuss Functions of rail tie plates. In a real-world application, single shoulder  Tie Plate  and double shoulder tie plate are the two types of most widely used rail tie plates. The use of single or double shoulder tie plates makes a more stable track and greatly lengthens the life of wood rail ties.  Punched and sheared from hot-rolled steel sections, Tie Plate For Rails  provide proper cant, uniform bearing surface for the rail and better load distribution to the ties. They hold the rail to gauge, providing more uniform wear to the railhead and protect against undue wear to ties. Railway tie plates are designed with a long end or field end to be located outside of the rails. In the case of single shoulder tie plates, the shoulder is placed on the field end of the plate. The gauge end or short end of the plate is located inside of the rails. When ordering, identification of the rail section or the width of...

Overview Of Rail Dog Spikes

图片
At our company, You always could get your favorite combination set of  Railway Accessories . On the construction of the railroad,  Rail Spike  is available in varying sizes to suit different applications.  Overview of rail dog spikes: 1. On the railway system, rail dog spikes can provide a strong, simple and inexpensive solution to securing rail track. 2. The method of manufacture ensures that the head and shank remain one solid piece of metal with no joins or welds. 3. Applications in many countries ranging from use in coal and gold mines to sugar plantations, peat works, garden festivals, and leisure parks as well as in some heavy rail applications. 4. Dog spikes may be manufactured in accordance with a number of international standards such as GB, AREMA or ASTM, BS, UIC. 5. Materials for rail dog spikes can be either carbon or stainless steels.

How To Select The Correct Rail Fastenings?

Here is  Steel Rail Supplier  talking about How To Select The Correct Rail Fastenings. If you have any idea about  Oem Railway Fasteners , welcome to contact us and discuss. The selection of rail fastenings must take into account the following factors: 1. track geometry 2. permissible and enhanced permissible speeds 3. track category 4. loads arising from braking and acceleration of trains 5. vehicle axle loads 6. electrical insulation requirements 7. underlying formation and structures supporting the track 8. the form of track construction.

Components Of Rail Fastenings

We have a professional R&D team and all the members work hard on the development and improvement of rail fastenings in each field. Rail Clips Rail clips are used to fasten the rails to the underlying baseplate. Rail Spike A rail spike (also known as a cut spike or crampon) is a large nail with an offset head that is used to secure rails and base plates to railroad ties (sleepers) in the track. Rail screw is a large (~6 in or 152 mm length, slightly under 1 in or 25 mm) metal screw used to fix a tie plate or fasten rail. Rail Tie Plate A tie plate is also called a baseplate or sole plate. Rail tie plate is used in rail construction to support the rails. Tie plates are generally used to take the load of rail and distribute the load to the sleepers offering proven economies. Rail insulator Rail insulator is used to adjust rail gauge and insulate the rail from ties and clips. Rail Pad The rail pad, originally called sole plate, is used when the rail is attach...

Functions Of Railway Fasteners

Here is  Rail Accessories Manufacturer  talking about Functions of rail fastenings.  If you have any idea about  Railway Fasteners , welcome to contact us and discuss. In a complete rail fastening system, every component is used to secure running rails into rail chairs or baseplates or directly to railway sleepers, bearers or other rail supports. Rail fastenings can keep the rails fastened to railway sleepers (transfer of forces), provide a proper slope of rail foot (1:20, 1:40) in the transverse plane, and prevent the steel rails from longitudinal movement, damp vibration, and noise coming from the rails. Functions of  Railway Fasteners : 1. Hold rails securely in the rail seat. 2. Limit the rotation of the rail about the outer edges of the rail foot. 3. Minimize longitudinal movement of rails through creep and thermal forces. 4. Assist in retention of track gauge. 5. Not cause damage to rail. Where practicable, rail fastenings shall either...
