World’s Quietest Caterpillar Truck

Print This Article

GHD has won international acclaim for its scientifically engineered quiet Caterpillar truck. Developed to comply with stringent noise standards in the Hunter Valley, the trucks are 20 times quieter than an untreated truck.

GHD scientists used advanced acoustics technology to limit the noise emitted by the engine, fan, transmission and differential of the Caterpillar 789C off-highway trucks. Reducing the noise level of the trucks was important because of the proximity of the nearby town of Muswellbrook, just 6km away. The stringent noise standards are regarded globally as industry-leading for open cut coalmines.

GHD’s noise capabilities are drawn from acoustic science, mechanical engineering and structural engineering disciplines.

Acoustic attenuation of earthmoving equipment brings with it the potential for higher engine operating temperatures and reduced service life. That is why GHD built a cooling system into the attenuation package to maintain Caterpillar’s optimum operating temperatures even in harsh earthmoving environment conditions.

The project was awarded the Certificate of Achievement - Specialist Services Category at the 2005 Association of Consulting Engineers Australia Awards for Excellence.
