PANDROL VANGUARD

PANDROL VANGUARD는 높은 수준의 진동절연으로 이어지는 매우 낮은 수직역학강성을 가진 독특한 레일 체결 장치입니다.

진동 및 2차 소음의 현저한 감소는 이러한 환경문제에 가장 민감한 분야의 어플리케이션을 이상적으로 만듭니다. Pandrol Vanguard 조립품들은 교량, 터널 및 고가교 위 콘크리트 침목과 목침목, slab track의 어플리케이션에 적합합니다. Vanguard는 새로운 궤도부설에 설치할 수 있으며 접지 소음 또는 2차 진동의 감소가 요구되는 기존 레일 체결 시스템을 보강하는데도 적합합니다. 이는 floating slab track보다 훨씬 저렴한 비용으로 탁월한 진동 감쇠를 제공합니다.

  • 4 kN / mm에 이르는 매우 낮은 수직 강성
  • 낮은 프로파일 시스템은 다양한 footpring design으로 쉽게 보강 될 수 있음
  • 높은 수준의 수평 및 수직 조절기능
  • 미래 보장 표준 강성 베이스 플레이트에 대한 기회
  • 사실상 유지 보수가 필요 없음

Vanguard는 새로운 궤도부설에 설치할 수 있으며 접지 소음 또는 2차 진동의 감소가 요구되는 기존 레일 체결 시스템을 보강하는데도 적합합니다.

  • (English) Why Vanguard?
  • (English) LRT/Metro
  • (English) Bridges
  • (English) Main Line (Passenger Freight)
  • (English) High Speed
  • Vanguard is a unique type of rail fastening. It provides a very low stiffness through rubber wedges which support the web of the rail and prevent excessive rail roll (dynamic gauge widening) which would normally occur on conventional baseplated systems. The nature of the rubber wedge support and the robust design of the assembly provides an ultra low maintenance system with a very long life expectancy in track.

  • (English) Vanguard Performance

    Vanguard has a natural frequency of approximately 20-25 Hz which provides the highest level of vibration attenuation that can be achieved in a surface mounted resilient rail support system. For attenuating track forms at lower frequencies the resilience needs to be provided under the concrete slab in the form of floating slab systems, please refer to Pandrol CDM Track for such requirements.

  • (English) New Installations

    Pandrol Vanguard can be installed on all types of construction methods. It can be provided for areas of a new build project where a high level of vibration attenuation has been identified as a requirement. The Pandrol Vanguard baseplates provides an exceptionally wide range of adjustment, typically +/-15 mm lateral per baseplate and +30 mm vertical, for more adjustment options please contact us. Because of it’s low profile Pandrol Vanguard can give the opportunity to reduce tunnel diameters, and therefore reduce costs for new track construction. Additionally, its low weight can lead to considerable savings in the cost of structures such as viaducts, which would otherwise have to accommodate the greater weight of floating slab-track.

  • (English) Future Proofing

    Many railway systems are built on the belief that the performance of the rail fastening system will be adequate for the environmental needs of the surrounding area. Unfortunately modeling the acoustic performance of a railway is not a precise science due to the unpredictable nature of the ground, wheel and rail conditions and whilst environmental impact studies mitigate some of the risk,  invariably there can be areas along the line where some vibration/secondary noise can create a public nuisance. The very low profile of Pandrol Vanguard compared to other low stiffness track forms means it can be installed within existing restricted rail heights and can therefore be used to increase the vibration isolation properties of an existing track form. That is something that we are doing in many existing railway systems. In fact, at the end of 2014 approximately 50% of all Pandrol Vanguard supplies have been installed in existing operating railways.

  • Pandrol Vanguard is suitable for LRT and Metro applications, it has been used on numerous projects in major cities throughout the world. For LRT/Metro applications Vanguard provides exceptional performance in 3 distinct areas.

    • Where DC power systems are used Vanguard provides extremely high levels of electrical insulation.
    • High levels of vibration isolation from the minimum 7 kN/mm dynamic stiffness.
    • The exceptional low maintenance inherent in the design of Vanguard.

     

  • Pandrol Vanguard is suitable for use on bridges to attenuate vibration which can otherwise lead to secondary noise from other parts of the bridge structure which may resonate. As Vanguard is an indirect baseplated system it can be applied directly to bridge girders or to the surface of timber, concrete or FFU bridge bearers and also on timber or concrete sleepers on ballasted bridge decks.

  • Pandrol Vanguard is suitable for use on Main Line (Passenger Freight) applications. It is suitable for installation on the surface of timber or concrete sleepers in ballasted track and also on all types of non ballasted track form.

  • Pandrol Vanguard is compliant with the requirements of the European High Speed TSI (Technical Standards for interoperability), and a declaration of conformity has been issued for use on ‘connecting lines’ at speeds less than 160 km/h
