Sistemas de fixação

NABLA Evolution

O NABLA Evolution é um sistema de fixação projetado para garantir uma instalação e manutenção simples.

Visão geral do produto NABLA Evolution

O sistema foi aperfeiçoado quando utilizado em vias com curvas de raio apertado, e aumenta significativamente a expectativa de vida dos componentes de montagem por mantendo a bitola da via.

  • O sistema tem sido amplamente utilizado em aplicações de bondes, para vias com lastro ou trilhos sobre laje com dormentes de concreto.
  • Oferece melhor isolamento elétrico e absorção de força lateral.
  • O uso exclusivo de material reforçado com vidro no isolador lateral também oferece maior resistência mecânica.

Advantages of NABLA Evolution

01

Low maintenance

Keep track maintenance overheads low with the Pandrol NABLA Evolution fastening’s deep post insulator, which offers exceptional resistance to wear caused by lateral loads.

02

Keep track maintenance overheads low with the Pandrol NABLA Evolution fastening’s deep post insulator, which offers exceptional resistance to wear caused by lateral loads.

Save time, money, and labour with a track fastening solution that is simple and quick to install, while still offering high performance and durability thanks to its high-quality components.

03

Durability

Rely on the NABLA Evolution’s unique construction to deliver durable results for years to come. The design utilises glass-reinforced material for high mechanical strength and lateral force absorption.

04

Superior insulation

Choose the NABLA Evolution rail fastening for its higher electrical insulation. The system is an efficient, effective, and safe option for tracks with tight radius curves – maximising the life span of all components.

05

Versatility

Benefit from the NABLA Evolution’s versatile nature. The system has been adapted for compatibility with all types of rail, including grooved, vignole, industrial, and AREMA. It is available in formats suitable for ballasted and slab tracks.

06

Adjustability

Achieve a good level of lateral adjustment via the NABLA Evolution’s insulators, which are optimised for fine gauge tuning. This adjustability aids in increasing the lifespan of rail components.

Technical features of NABLA Evolution

01

High clamping force

Prevent rail roll with the high clamping force of the NABLA Evolution. The fastening’s anchor screw is tightened to the contact, ensuring a consistent application of clamping force on the rail and a large range of torque.

02

Lateral force absorption

Choose a fastening solution with a high level of mechanical strength and good lateral force absorption. The NABLA Evolution fastening is constructed with specialised glass-reinforced material for durability and high performance under pressure.

03

Optimised coach screw

Achieve toe load automatically once the NABLA Evolution’s coach screw is tightened to contact. The screw offers a large acceptable torque range of between 250 and 400 Nm, making it versatile.

04

Adjustable insulators

Ensure a good level of lateral adjustment via the NABLA Evolutions insulators, providing excellent track gauge and alignment. Fine gauge tuning by 1.25mm increments, ±7.5mm per rail seat is achievable.

05

Electrical insulation

Achieve electrical insulation higher than standard NABLA systems with the NABLA Evolution’s enhanced capabilities. The fastening system provides electrical insulation of over 10 K Ohms (EN13146-5:2012).

06

Options for rail pads

Apply the NABLA Evolution fastening system to any rail system or environment, with a choice of rail pads from 35 MN/m for tramways, up to 400 MN/m and above for heavy haul applications and tight curves.
