Product Introduction
Nabla Clamp Railroad Fasteners System generally consists of Nabla elastic clips (shrapnel), connecting plates, etc., which are used to connect rails to sleepers.
Component features:
Elastic clips (shrapnel): Its special shape enables it to generate a dynamic and stable toe load on the rail when the nut is tightened, providing a strong clamping force and effectively preventing the longitudinal and lateral movement of the rail. It also has good fatigue resistance and is not easily damaged by fatigue under long-term repeated train loads.
Connecting plates and other components: They play the role of connecting and fixing elastic clips with sleepers and rails, and must have a certain strength and stability to ensure the reliability of the entire fastener system.
Mechanical properties of Nabla Clamp Fastenering System:
High strength: It can withstand the heavy loads generated by the passing of trains, maintain the integrity of the track, and ensure the safe operation of the train. For example, in high-speed railways, it can withstand the huge impact and vibration loads caused by the running of high-speed trains.
Good elasticity and vibration reduction: In addition to absorbing the vibration and impact energy generated by the running of trains and reducing the wear of track structures and train components, it can also effectively reduce noise and improve the surrounding environment. At the same time, its elasticity can adapt to the thermal expansion and contraction of the rails due to temperature changes, avoiding deformation or damage of the rails due to temperature stress.
