Product Introduction
SKL fastener system is a key equipment to ensure the fixation of rails in railway track engineering. It is composed of spring bars, insulating gauge blocks, elastic pads and other components. It achieves a close combination of rails and sleepers through mechanical fastening, effectively suppressing the displacement and deformation of rails. The system uses high-quality alloy materials, and the spring bars undergo special isothermal quenching treatment to obtain lower bainite structure, which has both high strength and high toughness; the rail pad is added with graphene reinforcement material, and the wear resistance is increased by 50%.
W14 fastener system is a spring clip fastener system commonly used in railway tracks.
Scope of application: Mainly used for concrete sleeper railways with ballasted tracks, suitable for high-speed (speed ≥ 250km/h) and ordinary speed (speed ≤ 250km/h) railways.
System composition
SKL14 spring clip: It is the core component, made of high-quality spring steel, and tightens the rail through elastic deformation to provide buckling pressure.
Sleeper screw: Used to fix various components on the sleeper.
Flat washer: Increase the contact area, prevent the screw from loosening, and protect the sleeper surface.
Gauge baffle: Maintain the gauge of the rail, with different specifications for gauge adjustment.
Rail pad: Placed between the rail and the sleeper, buffer the train load, reduce wear, and provide certain insulation performance.
Nylon sleeve: Pre-buried in the sleeper to provide an installation position for the sleeper screw.
Product Packaging & Delivery
Spring suspension + metal turnover box packaging: Multiple sets of spring suspension devices are installed inside the box. The fasteners that need to be shockproof are connected to the springs through hooks or special clamps, so that the fasteners are suspended. The elasticity of the spring can effectively absorb the vibration and impact during transportation. The box cover adopts a flip-top design, which is locked by a lock, and anti-collision rubber strips are installed on the periphery of the box.
