Product Introduction
Vossloh SKL Fastening Systems mainly consists of spring bars (such as SKL1, SKL3 and other models, providing buckling pressure), bolts and accessories (sleeper bolts, T-bolts, etc.), insulating components (insulating gaskets, insulating sleeves), pad components (rail pads, iron pads, elastic pads, height adjustment pads) and gauge baffles, plastic dowels, guide plates, etc. The components work together to achieve functions such as rail fixation, insulation, elastic buffering and gauge height adjustment.
Spring clip: It is a key buckling part. Common models include SKL1, SKL3, SKL12, SKL14, SKL15, etc. Different models may be made of spring steel such as 60Si2MnA, 60Si2CrA, 38Si7, etc. For example, the diameter of SKL15 spring bar is 15mm, and the diameter of SKL B15 (for small resistance of bridge) is 13mm.
Performance Advantages
Elastic fastening: The spring clip provides permanent elastic clamping force, which can effectively reduce rail wear. For example, the spring force of the SKL series spring bar is about 12kN/clip, and it meets the anti-climbing and anti-torsion requirements of the continuous welded rail.
Adjustment ability: It has a certain height and gauge adjustment ability. The height adjustment can be achieved by replacing different thickness height adjustment pads, and the gauge can be adjusted by using gauge baffles.
Compatibility and versatility: It can be applied to a variety of rail types (such as UIC54, UIC60, 50kg rail, 60kg rail, etc.) and track structures (ballasted track and ballastless track can be configured with different models). Some components are universal and there is also a certain compatibility between different models.
Product Application
Advantages of SKL Fasteners System in ballastless track
Excellent elasticity and vibration reduction: It can effectively reduce the vibration and noise generated by train operation, reduce wheel contact force, reduce track, substructure and vehicle wear, and provide passengers with a smooth riding experience. It is especially suitable for areas with high requirements for vibration reduction performance, such as subway tunnels.
Convenient installation and adjustment: It has height and lateral adjustability, flexible installation methods, and is based on a modular design concept, with high installation efficiency and low maintenance costs.
Durable: It meets the performance requirements of ballastless track for fastener systems, and the components are durable, which can ensure the long-term stability and reliability of the track structure.
Advantages of SKL Fasteners System in ballasted track
Simple and reliable structure: suitable for concrete sleepers, parts are fixed together to reduce the possibility of missing and improve installation and use efficiency.
Adapt to various needs: can be customized according to customer's special needs, such as dual-gauge system, special configuration of turnout area or use of anti-theft bolts, etc.
Good durability: the parts are made of excellent material and can adapt to the ballasted track environment. Parts such as spring bars are not easy to plastically deform, and corrosion protection can be selected according to the environment, with a long service life.
