A rail fish plate is a joint stabilization component that ensures rail ends remain in correct relative position, maintaining track geometry and operational reliability in jointed rail systems. GNEE RAIL offers fish plates for GB light and heavy rails, UIC50–UIC60, DIN536 crane rails, QU crane rails, JIS rails, AS1085 sections, BS11 standards, and AREMA/ASCE profiles.
What are the uses of fish plates?
Fish plates (or splice bars) are metal bars bolted to the ends of rails to connect them, ensuring structural continuity, alignment, and stability in railway tracks. They transfer vertical and lateral loads between rails, prevent rail separation, and reduce vibrations to improve safety and comfort.
Key Uses and Functions:
- Connecting Rails: Joins two rail ends together securely using bolts.
- Maintaining Alignment: Ensures proper alignment (both horizontal and vertical) of the rail surface and gauge face.
- Load Distribution: Transfers the weight of trains from one rail to the next, reducing stress on the joint.
- Structural Support: Provides stiffness to the rail joint, reducing deflection under heavy loads.
- Safety and Maintenance: Used in regular rail joints, insulated joints for signaling, and for emergency repairs of broken rails.
- Frame Reinforcement: In structural engineering, they are used to strengthen or repair joints in metal frames by overlapping the connecting pieces.
What is the size of a FishPlate?
Rail fishplates (joint bars) typically measure between 600mm and 1000mm in length, with 4 or 6 bolt holes, and are specifically engineered to match the height and profile of the rail, such as 305mm x 127mm x 38mm for certain standards. They are available in various weights, ranging from 10kg to over 25kg, tailored to rail types like UIC60, 115RE, and 132-136RE.
Railway Fishplate Dimensions and Types
- Length: Commonly around 600-1000mm, with 1-meter lengths used for specific applications.
- Bolt Holes: Standard plates typically have 4 or 6 bolt holes.
- Standards: Vary by rail profile (e.g., UIC50, UIC60, DIN536, AREMA).
- Weight: Ranging from light-duty (approx. 9.7kg for S49) to heavy-duty (up to 26.6kg for 132-136RE).
Common Size Examples:
- T-061 Standard: 305 mm x 127 mm x 38 mm.
- 115RE (6 hole): 36 inches.
- 132-136RE (4 hole): 24 inches.
- UIC60 (4 hole): 630mm or 790mm.
