Product Introduction
The railway fastener system is a track connection device composed of high-strength alloy steel spring bars, hot-dip galvanized bolts, nylon gauge baffles and composite rubber pads. According to the fastening principle, it can be divided into spring bar buckle type and bolt fastening type. The spring bar buckle type generates buckle pressure through elastic deformation. It is easy to install and reusable. It is often used in large-scale railway laying. The bolt fastening type fixes the rails by tightening the nuts. The fastening force is stable and reliable. It is suitable for special areas such as bridges and tunnels that require extremely high track stability. The system can effectively limit the longitudinal and lateral displacement of the rails and maintain the gauge accuracy under frequent train loads. At the same time, the composite rubber pads can absorb vibration energy, reduce noise pollution, and extend the service life of track components.
The Nabla railway fastener system has excellent fatigue resistance and is suitable for high-volume, high-frequency railway lines. The Nabla spring clip adopts a unique mechanical structure in design, combined with the high fatigue strength characteristics of alloy spring steel, which can maintain a stable buckle pressure under long-term repeated train loads and reduce the risk of spring clip fatigue failure; high-strength bolts, nuts and other connecting parts reduce stress concentration and improve fatigue resistance through precise thread design and surface treatment technology. At the same time, the overall structure of the system reasonably disperses the alternating stress generated by train operation, prolongs the service life of track components, and reduces line maintenance costs.
Product Specifications
Product Packaging & Delivery
Use foldable wire mesh cages to pack large irregularly shaped fasteners. The cages are welded from high-strength steel wire and have foldable brackets at the bottom and around. After placing the fasteners in the cages, unfold the brackets to secure them, and cover the top of the cages with metal mesh plates and fasten them with bolts. Multiple cages can be stacked during transportation, and then connected in series with iron chains. When not in use, they can be folded into a flat plate to save storage space.
