In the railway track system, FIST Railway Fastener System is a key technical equipment to ensure the stability of the track and the safe operation of the train. With its unique design and performance advantages, it occupies an important position in modern railway construction.
FIST Railway Fastener System is mainly composed of spring bars, gauge baffles, insulating gauge blocks, rubber pads and other components. As the core elastic element, the spring bar generates buckling pressure through its own elastic deformation to buckle the rails to the sleepers or track plates; the gauge baffles and insulating gauge blocks play the role of fixing the gauge and providing insulation performance; the rubber pad can buffer the vibration and impact force generated by the train running, and reduce the wear between the rails and the sleepers. The various components cooperate with each other to form a tight whole, effectively maintaining the geometric shape and position of the track.
Performance advantages
High elasticity and stability: The spring bar design of the FIST system has excellent elasticity, which can adapt to the dynamic load caused by the frequent passage of trains, ensure that the rails are always in a stable state, and reduce the risk of track deformation.
Good insulation performance: The application of components such as insulating gauge blocks can effectively isolate the current conduction between the rails and the sleepers, prevent stray current from corroding the track structure and surrounding facilities, and improve the service life of the system.
Easy installation and maintenance: Compared with traditional fastener systems, the FIST system has a simple structure, a more efficient installation process, and is more convenient for later inspection and replacement of components, which can effectively reduce maintenance costs and time.
The FIST railway fastener system is suitable for a variety of railway scenarios, including high-speed railways, urban rail transit, and heavy-duty railways. On high-speed railways, it can ensure that trains run smoothly at speeds of more than 300km/h; in urban subways, light rails and other rail transit, it can effectively reduce train running noise and reduce the impact on the surrounding environment; on heavy-duty railways, in the face of huge axle weights and frequent train loads, it can still maintain track stability and ensure transportation safety.
