Products Description
Railway sleeper dog spikes play a vital role in the track system. Their main function is to fix the rails, ensure the geometric stability of the track, and prevent the rails from shifting when the train is running. Through their specific specifications and design characteristics, the spikes effectively connect the rails and sleepers as a whole, thereby ensuring the safety and smooth operation of the train.
Heavy-duty railway road spikes need to withstand a load of more than 30 tons. The head is designed as a trapezoidal structure to increase the contact area with the sleeper. The bottom thread adopts a double-line design to improve the pull-out resistance.

Product Features：
Effective protection against track displacement
Modern railway spikes mostly adopt spiral or threaded structures to enhance their locking force in the sleepers and effectively resist loosening caused by dynamic loads.
At the same time, the matching pads and elastic parts also further enhance their seismic performance.
Excellent pull-out resistance
The pull-out resistance of the railway sleeper dog spikes determines whether it can be firmly fixed in the sleeper for a long time.
During the passage of the train, the railway sleeper dog spikes is not only subjected to vertical pressure, but also some upward vibration force.
