Combining ease of application with high-performance levels, NABLA Tram is compatible with both top-down and bottom-up construction methods, depending on a project’s requirements. The baseplate is designed to allow effective insertion into a dry mix or fresh concrete, thanks to an air evacuation system consisting of blowholes and channels
NABLA Tram has been designed for ease of installation using either bottom-up or top-down construction methods, into either a dry mix or fresh concrete.
Covers are compatible with grass, pavement, concrete and bitumen surfaces. They increase the insulation and protect the fastening system from concrete contamination.
The baseplate allows trapped air and water to escape, increasing the system’s reliability.
NABLA Tram’s GS anchorage provides pull-out resistance of 90kN and higher, allowing a good transfer of loads towards the concrete slab.
The system can be adjusted to provide a wide range of stiffnesses (from 35 MN/m up to 150 MN/m) and vibration attenuation better than -10dB.
NABLA Tram is suitable for use in conjunction with Pandrol’s QTrack sustainable resilient system for embedded rail.
The plastic baseplate is partially embedded in the concrete to withstand the lateral and longitudinal loading. It is engineered to allow trapped air and water to escape, ensuring a solid fill of concrete under the rail seat.
NABLA Tram is a direct fastening system. The rail is attached to the baseplate and the baseplate to the supporting base structure using the same method.
The baseplate system has been optimised for automatic machine installation on slip paved fresh concrete. Its shapes, dimensions and weight allow for easy, economical installation.
The fastening system comes with a plastic cover designed to prevent concrete contamination, and improve electrical, mechanical and thermal resistance, allowing for road traffic.
The NABLA air evacuation system prevents trapped air getting under the baseplate.
NABLA Tram provides electrical insulation higher than 20 K ohms (EN13146-5:2012), providing safety from stray currents.
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.
