What Hushpak products can Trackspares supply?

Hushpak is pleased to partner with Trackspares, supplying them with our noise attenuation equipment including sound suppressed idler wheels and track dampers for large dozers in the mining sector.

Idler Wheel Treatment

Hushpak is renowned for developing a successful and cost-effective method for damping idler wheels. Field testing has shown Hushpak idler wheel treatment reduces the overall sound level of the dozer under most operating conditions.

Attenuated idler wear rate is identical to non-attenuated idlers. Reconditioning of attenuated wheels is a practical alternative to complete wheel replacement.

Track plate dampers

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 4 dB(A) can be achieved.

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 4 dB(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 custom-designed exhaust mufflers and engine bay treatment.

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.
