Fish Plates (also known as rail joint plates or splice bars) are essential components in railway track construction and maintenance. They are used to join two sections of rail together, providing structural support and stability to the track. Fish plates are available in various weights and designs, with 52 kg and 60 kg variants commonly used in different railway systems.
Fish Plate Specifications
1. 52 kg Fish Plate:
- Weight: 52 kg (approximately 114.6 lbs)
- Material: Typically made from high-strength steel, ensuring durability and resistance to wear.
- Dimensions:
- Length: Standard lengths usually range from 300 mm to 600 mm, depending on design and application.
- Width: Common widths range from 100 mm to 150 mm.
- Thickness: Typically around 20 mm to 25 mm.
- Usage: Suitable for joining lighter rail sections, primarily used in light rail applications and specific regional rail networks.
- Fastening: Usually secured with bolts and nuts, which may require specific installation tools for proper tightening.
2. 60 kg Fish Plate:
- Weight: 60 kg (approximately 132.3 lbs)
- Material: Made from high-strength steel for enhanced durability and longevity in demanding rail environments.
- Dimensions:
- Length: Standard lengths similar to the 52 kg variant, typically ranging from 300 mm to 600 mm.
- Width: Common widths range from 100 mm to 160 mm.
- Thickness: Typically around 20 mm to 30 mm.
- Usage: Designed for joining heavier rail sections, primarily used in high-speed rail and heavy freight applications.
- Fastening: Similar fastening methods as the 52 kg fish plate, often using bolts and nuts for secure attachment.
Key Features and Benefits of Fish Plates:
- Structural Integrity: Fish plates provide necessary strength and stability at rail joints, ensuring that the rails remain aligned and properly supported.
- Load Distribution: They help distribute the weight of passing trains evenly across the joint, reducing stress and potential damage to the rails.
- Durability: Made from high-quality materials, fish plates are designed to withstand environmental conditions, including corrosion and wear from heavy rail traffic.
- Ease of Installation: Fish plates can be installed quickly with standard tools, making them a practical solution for rail maintenance and repairs.
