Rigid Contact Tuned Mass Rail Damper

Guarantee 4-10dBA noise reduction
For noise problems due to rough rail surface or soft fasteners, performance would be superior and up to 10dBA is guaranteed.
90% corrugation growth rate reduction
The only rail damper in the world to both reduce noise and suppress corrugation.
3-10 dB groundborne noise reduction (P2 resonance)
8dB floor vibration reduction in laboratory simulation of railway P2 resonance.

Our professional team offers consultation service to evaluate the performance of Rigid Contact Tuned Mass Rail Damper

Q Grinder

Portable and battery power
Q Grinder can be deployed in short notice and atypical location and operable up to slope of 30 degree. Our patented technology ensure even grinding without complex mechanical design.
Longitudinal grinding marks
In line with the train traveling direction, no extra noise generation after grinding.
Diamond grinding head
This ensure realizable grinding performance across the running band. Our patented technology ensure even grinding by the diamond grinding heads without complex control system and mechanical design.
