Product Introduction
Railway fastener systems are composed of elastic clips, pads, bolt assemblies, etc., and can be divided into low-speed, medium-speed, and high-speed special fastener systems according to the railway operating speed. The fastener system for low-speed railways focuses on the stability of the structure and can meet the heavy-load requirements of freight trains; the system for medium-speed railways takes into account certain elasticity and vibration reduction performance while ensuring stability; the system for high-speed railways has extremely high requirements for precision and performance. Through precise design and manufacturing, it ensures the high smoothness of the rails at high speeds, reduces train running resistance and noise, improves passenger comfort, and ensures driving safety.
KPO Clamp Fasteners System is mainly composed of clasp, threaded spike, spring washer, iron seat and buffer pad.

Clamp is the key component for directly clamping rails. Its shape and size are carefully designed to fit the shape of the rails tightly and provide stable and effective clamping force.
Threaded spikes are used to firmly fix the clasp on the sleeper, and through cooperation with the reserved holes of the sleeper, a reliable connection is achieved.
The existence of spring washers plays a role of buffering and preventing loosening. Under the vibration and impact generated by the train operation, it can effectively prevent the threaded spikes from loosening and ensure the stability of the entire clamp system.
The buffer pad is set between the clasp and the rail, which can not only reduce the direct impact of the train load on the rail, but also play a certain insulation role to meet the relevant requirements of the track circuit.
