Hushpak Engineering has your solution to dozer noise. Our understanding of noise, together with our proven track record, tailored approach and readiness to take on a challenge enables us to solve your noise problem.
Idler Wheel Treatment
Undercarriage noise attenuation of dozers
Understanding Idlers
Noise reverberates through both the track plate and the idler wheel. Effective damping of the idler wheels can achieve a 3 dB(A) noise reduction from each idler, giving an overall reduction up to 5 dB(A). Following this
modification, the dominant source of noise is from the grouser plates as the track chain impacts the sprocket
and idlers.
Idler Wheel Treatment
Hushpak has developed a successful and cost effective method for damping idler wheels. Field testing shows 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.
To complement undercarriage noise reduction, Hushpak offers a range of additional dozer noise attenuation packages, including treatment of:
- Exhaust
- Engine Bay
- Cabin
- Track Plate or Grouser Dampers
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.
... we are the quiet achievers
Hushpak continues to lead the way in research and development of
dozer noise attenuation solutions. Our products and treatments successfully meet the challenge
brought by the harsh environment of an operating dozer, while retaining suitable acoustic
attenuation performance
