What are the differences between different elastic strips?

As a railway accessory, although the elastic bar plays a very important role in the entire railway line, it can also be divided into different specifications.

Through the bending and deformation of the elastic bars, fastening pressure is applied to the rails, which can ensure long-term reliable connection between the rails, ensure the integrity of the rails, and prevent the rails from moving relative to the longitudinal and horizontal directions. Sleepers ensure the safe operation of rail vehicles. In order to let users have a better understanding of elastic fasteners, the following is an explanation of the difference between type I elastic fasteners and type II elastic fasteners.

1. Different withholdings. The clamping pressure of type I spring fastener is insufficient; the spring bar of type II spring fastener is higher than that of type I spring fastener.

2. The scope is different. The elastic range of type I spring fasteners is small; the diameter of type II spring fasteners is relatively large, not less than 10mm.

3. Different guide rails can be used. Type I elastic fasteners are generally used to fix 50kg/m rails; type II elastic fasteners are used to connect 60kg/m rails.

The spring bars work under repeated alternating stress. It has many functions such as anti-bending, anti-torsion, anti-fatigue, anti-corrosion and so on. When vehicles pass by, they are also subjected to high instantaneous impact loads, so the performance requirements for spring fasteners are very strict.
