Rail Track Isolation Systems - Trelleborg.com.au

Floating Slab Track (FST) BearingsFloating Slab Tracks (FST’s) are a proven mass-springsystem for achieving very high levels of vibrationisolation. The degree of isolation achieved on ourmost recent installations is far superior to almost allother available systems of track form. In particular,FST bearings are suitable for reducing low frequencyground borne vibrations.We have recently supplied FST bearings for theextensive Hong Kong rail system, including :-• KCRC West Rail• KCRC East Rail Extensions• MTRC Lantau and Airport Railway Phase 2Our FST bearings are manufactured using a specialdual compound design to ensure consistent long-termperformance. The bearings are principally NaturalRubber to provide excellent mechanical properties,extended durability, low creep rates and low dynamicto-staticstiffness ratios. In regards to their provenrecord of long-term durability, some elastomericbearings in bridge support applications have beenoperational for in excess of 100 years.We supply custom designed bearings to supportvertical, lateral and longitudinal loads applied to eachspecific Floating Slab Track unit. The bearings can bedesigned to support pre-cast and in-situ slab systems.In addition to extensive development trials andrepeated cyclic tests on prototype samples, thebearings are comprehensively tested duringmanufacture to ensure consistent compliance with thespecified performance requirements.
