Track Plate Treatment
Undercarriage Noise Attenuation
Understanding Track Plates
Noise is emitted at the track plates (also known as grousers) as they impact on the sprockets and idler wheels. The grousers act like a sound board and reverberate at multiple frequencies significantly adding to the tonal noise of the machine. An overall reduction of up to 6dB (A) can be achieved.
Track Plate Dampers
Installation of track plate dampers minimises reverberation of the track plates or grousers when the track chain strikes the sprockets and idlers. Track plate dampers are effective at removing up to 6dB(A) from the dozer sound power level and improve operator comfort.
To complement undercarriage noise reduction, Hushpak offers a range of additional dozer noise attenuation packages, including treatment of:
- Exhaust
- Engine Bay
- Cabin
- Idler Wheels
As dozers vary within each mine site, the noise reduction required and the role of the dozer must
be considered before deciding how to best mitigate the problem.
