Loadquip has been involved in the cost effective acoustic treatment of mining equipment for a number of years. The company has supplied a number of vehicles with ROPS cabs which are acoustically treated to provide acceptable levels of noise at the operator position.
Loadquip has also been involved (and are currently involved) in the acoustic treatment of various items of mining equipment to provide acceptable external noise levels to permit deployment in various regions of the Hunter Valley and other noise-sensitive areas. The equipment includes large rear-dump trucks, large hydraulic excavators, blast-hole drills and large wheel loaders. Treatment techniques include substitution of quieter fans, addition of absorbent material and acoustic barriers, larger mufflers, and acoustic louvres.
