Major Mine Site

Hushpak undertook sound proofing of over 20 heavy coal and haulage trucks (190 and 240 tonne). This required extensive soundproofing of their engines and exhausts. Soundproofing was also carried out on five, 100 tonne dozers – involving their fans, engines and tracks. Similar high levels of sound attenuation were achieved on a large 24 foot grader and a large rubber tyred dozer.
