There are many types of railway spikes. According to different structures and uses, they can be mainly divided into ordinary spikes, spiral spikes, threaded spikes, spring spikes and other types. Different types of spikes are suitable for different track structures and line environments. Reasonable selection is crucial to ensure the safety and economy of the track system.
Ordinary railwa spikes have a simple structure and are often used in wooden sleeper lines. They are widely used in traditional railway construction. Its advantages are low cost and simple construction, but the holding force is limited and it is easy to loosen due to long-term vibration. Therefore, the proportion of use in modern high-speed or heavy-load railways is gradually decreasing.
Spiral spikes are fasteners with a spiral shape, which have strong holding force and pull-out resistance. They are suitable for areas with large vibration or lines with high safety requirements. Its installation requires special equipment and the construction efficiency is relatively high.
Threaded spikes are generally used in conjunction with sleeves in concrete sleepers and are a common fastener structure in modern railways. This type of spike is firmly installed, detachable, and reusable, and is widely used in high-speed rail, urban rail, freight lines and other lines.
In addition, there are special structures such as spring bar matching threaded spikes and stud screws, which are used for curved sections, heavy-load sections, or special fastener systems. When communicating with customers about products, companies should fully understand the customer's track system structure and construction requirements, and provide applicable spike models and installation solutions to maximize product value.
