Fastclip for Railway Fastening Systems

The fast spring bar produced by Gnee is corrosion-resistant and wear-resistant, and can be used in multiple tracks. You tell us the scenario you need to apply, and we can help you choose the most suitable spring bar.

FC1504 Spring Clips

Ordinary Railway

• Straight section: FC1504 spring bar can effectively fix the rail on the sleeper with its suitable diameter, good buckle pressure and spring range, ensuring the safety and stability of the train when running on the straight section.
• Curved section: FC1504 spring bar can maintain a stable buckle pressure under the condition of bearing the lateral force and longitudinal force generated by centrifugal force through reasonable structural design and material selection, preventing the rail from lateral movement and longitudinal creep.
• Ballasted track: In the ballasted track of high-speed railway, FC1504 spring clip can provide high and stable buckling pressure, effectively fix the rails, and reduce the vibration and displacement of the rails when the train runs at high speed;
• Ballastless track: FC1504 spring clip can also play an important role in ballastless track. Its good buckling pressure and elastic range performance can adapt to the structural characteristics of ballastless track, effectively fix the rails on the ballastless track plate, and ensure the safety and stability of the train when running at high speed on the ballastless track.

Urban Rail Transit

• Underground line: Due to its compact structure and suitable size, FC1504 spring clip can be smoothly installed in the limited space of underground line, and can achieve good coordination with other track components.
• Ground and elevated lines: FC1504 fast spring clip can provide reliable buckling pressure and good elastic deformation ability, effectively absorbing the vibration and impact energy generated by train operation.

FC1306 Fast Clips

Lower Resistance Fastener Area

• Elevated bridge track seamless line: The smaller buckle pressure of FC1306 spring bar can effectively reduce the longitudinal resistance between the rail and the bridge while ensuring the fixation of the rail.
• Tunnel track seamless line: When FC1306 spring bar is used in the tunnel track seamless line, its smaller buckle pressure can effectively reduce the interaction force between the rail and the tunnel structure, and reduce the stress and deformation of the tunnel structure.

Locations With High Requirements For Track Elasticity

• Station throat area: FC1306 spring bar can effectively absorb the vibration and impact energy generated by the train due to its good elastic range performance, provide good elastic support for the track, and improve the service life and stability of the track in the station throat area.
• Sections with small curve radius: When FC1306 spring bar is used in sections with small curve radius, its good elastic range performance can effectively absorb the vibration and impact energy caused by the centrifugal force generated when the train passes through the curve, provide good elastic support for the track, reduce the lateral deformation and longitudinal displacement of the track structure under the action of centrifugal force, and prevent the rail from lateral movement and longitudinal creep.

FC1502 Clips

Rail clamp

• Ordinary railway rail connection: FC1502 spring bar is specially used in rail clamp, with a diameter of 15mm and the design feature of not installing insulating cap, so that it can achieve good cooperation with rail clamp and other track components.
• Heavy-duty railway rail connection: Gnee’s FC1502 spring bar can provide sufficient buckling pressure at the rail clamp of heavy-duty railway with its high-strength material and reasonable structural design, ensuring a firm and reliable connection between the rail clamp and the rail, ensuring the stability and safety of the heavy-duty railway track structure, and meeting the high requirements of heavy-duty railway for track structure.
