Q Grinder for rail track: specifically designed for steep slope rail grinding when conventional rail grinders are inoperable

Rail Damper

Our rail tuned mass damper is the world’s first capable of reducing groundborne noise of trains (5 – 8 dB of reduction) and very effective in corrugation mitigation (over 90% of reduction in corrugation growth rate).

Patented rigid-contact interface provides 100% vibration transmission between damper and rail, allowing the strongest damping force to counteract rail vibration.

Its compact size also makes it easy to install and allows rail inspections.

It is especially suitable for retrofitting the curved tracks.

Hong Kong West Island Line

Year: 2020

Achieved 6 dB(A) overall noise reduction and 6dB(A) overall rail vibration reduction with only 5 dampers installed.

London Underground Trial

Year: 2019

Achieved 2dB(A) Rail Side (2.5m) Noise Reduction and 6dB(A) overall rail vibration reduction with only 5 dampers installed.

Hong Kong East Rail line

Year: 2016

For a 100m long damper section, one set of damper per rail support spacing, Q Damper provides 10dB(A) rail vibration reduction and 18dB vibration reduction at 1250Hz.

Zurich

Year: 2018

Although only 5 dampers were installed, 2 dB(A) overall noise reduction was already achieved, measured 2.5m from the noisy side of rail (facing the rail without dampers).

Rail dampers are the next-generation solutions to railway noise problems. Our rail dampers, invented by our sister company Jabez Innovation Limited, offer 5 unique advantages

Tunable effective frequency ranging from 40Hz to1600Hz

Corrugation growth suppression up to 90%

Rail noise reduction up to 12dB(A)

Groundborne noise reduction up to 8dB

Rail vibration reduction up to 18dB

Groundbourne noise reduction

Corrugation control

Vertical Pole Diffuser

Vertical pole diffuser is an innovative traffic noise barrier system.

It provides at least 5 dB(A) of noise reduction, but only induces 80% less wind loading compared to the conventional noise barrier.

This makes it the most viable option for retrofitting existing viaducts, which may not be able to sustain high wind loading in structural designs.

Introduction

Q Grinder for rail track

Q Grinder, patented in 2022,  is specifically designed for steep slope rail grinding (slope ~ 25), at which conventional rail grinders are inoperable.

It adopts magnetic attraction and diamond grinding head to control grinding pressure and improve grinding efficiency respectively.
