directly affect the stability and safety of the track system. Depending on the usage scenario and track type, the size parameters of the
are significantly different.
For example, ordinary railway spikes: The length is usually between 85mm and 120mm, and the diameter ranges from 16mm to 22mm. This type of railway sleeper dog spikes
is suitable for rails of 43kg/m to 60kg/m.
High-speed railway spikes: In view of the operating speed of high-speed railways and the high requirements for stability, the length of the spikes is generally above 150mm and the diameter is not less than 24mm. Such a specification design can cope with the lateral force generated when running at a high speed of 350km/h.
which has extremely high economic and time value for large-scale railway construction projects.
The track system will generate lateral and longitudinal vibrations and thrusts when the train is running at high speed.
If the grip of the railway sleeper dog spikes is insufficient, it may cause the rails to slip or the fasteners to loosen, posing a safety hazard.
