Track and boat spikes are essential, large, offset-head nails securing rails to wooden sleepers (ties) in railways, with dog spikes (chisel-point, driven across grain) providing strong grip for main track, while boat spikes (often diamond-head, used for lighter duties like turnouts/fleeting) offer robust, simple fastening, complementing other fasteners like screw spikes for stability, gauge maintenance, and load bearing in various rail systems.
Kunshan Signum Machinery Technology manufactures four sizes of Track and Boat Spikes. 3/8′′, 1/2′′, 9/16′′ and 5/8′′. All spikes are manufactured to latest AREMA specifications in both soft steel and high carbon varieties.
Key Types of Spikes:
Key Types of Spikes:
Dog Spikes: The most common, with a chisel or wedge-shaped point driven perpendicular to the wood grain for maximum holding power against rail movement, keeping the rail in gauge.
Boat Spikes (Diamond Spikes): Similar to dog spikes but often with a diamond or square head, used for lighter applications, switches, or where ease of removal/replacement is needed.
Screw Spikes: Large metal screws with threads, offering superior holding power and used with baseplates, sometimes on concrete ties as well as wood.
Function & Importance:
Function & Importance:
Securing Rails: They hold the T-shaped rail section and the baseplate firmly to the wooden sleeper (tie).
Gauge Maintenance: Prevent the rails from spreading apart or moving inwards, ensuring safe track width.
Load Transfer: Transfer dynamic forces from the rail into the sleeper.
Characteristics:
Characteristics:
Offset Head: The head is offset (not centered), allowing the spike to be driven with its point against the grain for better grip.
Material: Typically made from low or high carbon steel(In China, it can be q235,35#,45#,etc).
Strength: Engineered to resist constant vibration, heavy loads, and environmental stresses.
Standards: Kunshan Signum Machinery Technology Co., Ltd produce track and boat spikes to meet AREMA standards, ensuring the necessary strength and durability for heavy-duty applications.
Holding Power: A correctly installed spike in sound timber can provide significant withdrawal resistance (approximately 5,000-7,000 pounds), which is crucial for maintaining rail alignment under the forces of passing trains.
