Among the many types of rail fastening systems, SKL12 rail fastening system and slab track fastening system are the two types of hot sale products. Next are the specifications of SKL12 fastening system and slab track fastening system.

SKL12 Rail Fastening System with Screw Spike, Plastic Dowel, Elastic Clip, Rubber Pad And Guide Plate

SKL12 type fastening system is a highly elastic rail fastening system for concrete railway sleepers. The SKL12 railway clip permanently clamps the steel rail to the concrete sleeper.
skl12 fastening system
Rail fastening system is a means of fixing rails to railroad ties (United States) or sleepers (international). The terms rail anchors, tie plates, chairs and track fasteners are used to refer to parts or all of a rail fastening system. Various types of fastening have been used over the years.
Railway screw spike, rail screw (or lag bolt) is a large (~6 in or 152 mm length, slightly under 1 in or 25 mm) metal screw used to fix a tie plate or fasten rail. Screw spikes are fixed into a hole bored in the sleeper.
Rail tie plate, baseplate or sole plate is a steel plate used on rail tracks between flanged T rail and the crossties. The tie plate increases bearing area and holds the rail to correct gauge. They are fastened to wooden ties by means of spikes or bolts through holes in the plate.

Slab Track Fastening System

Slab tracks meet all the requirements for combined high speed and heavy load traffic. The 300 rail fastening system for slab tracks, which can be pre-assembled, is suitable for all methods of slab track installation. The highly elastic intermediate plate substitutes for the elasticity of the ballast bed. A steel pressure distribution pad, which supports the rail through the interposition of conventional rail pads, is used to improve the load distribution on the intermediate plate.

The rail is held laterally in position by plastic, angled guide plates. The rail is permanently tensioned by spring-actuation as a result of the long elastic spring deflection of the SKL 15 tension clamp.
The rail fastening system 300 can be adjusted by up to 76 mm in heights and by +/-16mm in track gauge.
High quality of plastic for rail fastening system
As we all know, rail fastenings are the structural elements in a permanent way that are subjected to the most intensive loads. The ability of plastics to be matched to the particular requirements in respect of the geometry of the product and the properties of the material have given them their top position for nearly all rail fastening components. In this segment we fabricate all the parts employed in rail fastenings from structural plastics.

Rail pads / base plate pads for fastening system

Performance of AGICO microcell EPDM rail pads and base-plate pads:
  • High resilience
  • Excellent noise and vibration damping
  • Minor change of the spring rate in the working temperature range (tested at temperatures of -50°C to +100°C)
  • Excellent ageing and weather resistance
  • Least water absorption (closed-cell)
  • Excellent UV- and ozone stability
  • Low frequency dependence between 1 Hz and 30 Hz (under dynamic load)
  • Enormous hydrolyse stability
The applied EPDM elastomer has in its chemical structure a saturated polymer main chain that causes a high stability against a variety of chemical attacks. This explains the material’s extraordinary thermal, ageing and weathering behavior as well as its excellent durability.
The microcellular rail pads and base plate pads show the desired stiffness in the relevant load area, they have a circular cavity in their middle and are thinner in the area of contact with the rail foot. It is thereby achieved that at an equal vertical stiffness the rail configuration in the outer rail foot area has a higher stiffness (no tilting).
AGICO Rail is responsible for the production of railway tension clamps, rail joint bars, railway clips, rail tie plates, steel rails, and also for the production of rail pads, rail fastening systems and high-speed rail fastening systems.
