The railway fastener system is a key component combination to ensure the safe and stable operation of railway tracks. Its main task is to firmly fix the rails on the sleepers, ensure the accuracy of the gauge, and prevent the rails from moving vertically and horizontally. Common classifications include SKL, KPO, Nabla, WJ-8 and other types.
For example, the KPO type gusset fastener system consists of gussets, bolts, nuts and other components. The gussets are made of high-quality carbon structural steel, and the surface treatment improves the rust and wear resistance. It is suitable for general laying of railways, especially for lines with high requirements for installation and maintenance convenience. It can meet the track fastening requirements at a lower cost.
Rail Fastener System WJ-8 is used for high-speed railways. The spring bars are made of advanced high-strength spring steel. After special process treatment, they have extremely high fatigue life and stable buckling pressure; the insulating gauge block is made of high-performance insulating material. In the high-speed electrified railway environment, it effectively prevents the corrosion of the track structure by stray current, ensures the normal operation of the track circuit, and ensures the safe and efficient operation of high-speed trains.
