Bolting is a traditional method used in engineering for creating a fixing. The GNEE RAIL bolted (boltable) rail clips are the simplest and easiest to install. The clips can be used with different grades of bolt (8.8,10.9) and some clips can be fitted with preinstalled weld studs welded to the steel rail support surface.
The Bolted Rail Clip is a widely used rail fastener designed to secure rails onto sleepers with the help of bolts. It prevents the rail from lateral and longitudinal movement, ensuring track stability and safety. Featuring easy installation, convenient maintenance, and strong versatility, bolt type rail clips are suitable for various rail types and operating conditions. They are commonly applied in railway tracks, light rail systems, mining tracks, and industrial rail transportation.
Installation Procedure of Bolted Rail Clip
- Insert bolt(s) through hole(s) in rail supporting structure, ensuring the bolt is placed vertically and passes through all holes correctly.
Place body of clip over bolt(s) with rubber 'nose' resting on upper surface of bottom flange of rail.
- Move clip into metal-to-metal contact with bottom edge of rail.
- Bottom face of clip will not be in full contact with rail support.
- Place special washer(s) over bolt(s) to distribute load evenly and improve stability.
- Make sure special washer(s) is fitted correctly with square corner to back and flat surface upwards.
- Run nut(s) down bolt(s), lowering them gradually until they reach the washers.
- Nuts to make contact with special washer(s).
- Tighten nut(s) with spanner, applying even pressure during tightening.
- Tighten only until rubber 'nose' is compressed and bottom surface of clip is in full metal-to-metal contact with rail support. Do not apply full torque yet.
- With hammer of about 1kilo, tap clip body towards rail along direction of slots in clip.
- Tighten nuts to require torque given on product datasheet.
