This versatile system can be used on both standard track and turnouts. A single fastening system can be used for the whole track system as the standard model is designed for running track and customised models are designed for switching zones.
The ADH System provides both vertical and lateral stiffness via two independent cast baseplates.
The ADH System has particularly high corrosion resistance because the plate is covered with rubber, which acts as a protective barrier between the baseplate and the atmosphere.
The system’s low stiffness decreases the dynamic load level by reducing vibrations transmitted to the ground and distributing them along the supports. As a result, vibrations are isolated and noise generated by the moving wheels on the rail is attenuated.
The system provides a specific longitudinal restraint, good track elasticity, and reduced stress in the rail when exposed to high temperatures.
The system provides electrical insulation for the rail, isolating it from the track bed and avoiding electrical leakage into the ground. In addition to this, the system has a high level of stray current protection.
The DFF assembly has a fail-safe design, remaining active and safe in situations where bond failure between rubber and metal components occurs.
Installation of the ADH System is simple, enabling the entire assembly, or any of its components, to be installed or replaced by one person using hand tools.
The ADH system is available in two- and four-hole offset and two-hole line footprint configurations. This gives the best possible solution for new build, track renewal and retrofit applications.
To meet specification requirements, the ADH System is available with a variety of clip types, including e-clip, SD, SLK, Nabla and FE.
The system’s unique bonding process achieves very high levels of electrical resistance and long electrical leakage paths. Tests against EN Standards have shown electrical insulation performance several times higher than the minimum required.
The ADH system comes in a variety of lengths, with different base plate lengths and options to suit all turnout applications. The system is also suitable for steel bridges and ballasted tracks.
Rail fastening clips are available in low toe load and zero longitudinal restraint (ZLR) configurations. This makes the system ideal for use on bridges and viaducts, when the effects of track-structure interaction need to be considered in the rail fastening assembly.
The SD-HH fastening system is quick and efficient to instal with few tools and minimal training.
The modern heavy haul railway is a demanding environment, with high locomotive horsepower, dynamic braking, large rail sections and high mega gross tonnes per year.
Pandrol’s Fastclip FE RR rail fastening system is designed specifically for extreme heavy haul applications. It is suitable for an axle load of up to 40 tonnes and curve radius down to 150 metres.
The DRS baseplate is a double-resilience e-clip fastening system that is ideal for use on non-ballasted tracks when ground-borne noise and vibration reduction are required.
Pandrol Fastclip is an established, highly-regarded resilient, threadless rail fastening. Over the years, the Fastclip family has grown to include the FC, FD, FE Fastclip products, each of which has been designed to meet the technical and commercial demands of a specific area.
The rail seat assembly is typically made up of two tension clamps (SKL clips) on top of angled guide plates on each side of the rail.
NABLA Evolution is a direct rail fastening system that offers enhanced performance for tracks with tight radius curves. It has been proven in installations for several decades and is recognised for its simple installation and maintenance. By maintaining the track gauge, it significantly increases the life expectancy of assembly components.
