Caterpillar 775G Case Study: Dump truck sound attenuation

Case Study

Caterpillar 775G Minetek Sound. Dump truck sound attenuation.

| Sound

Caterpillar machine noise reduction.

Business Challenge The Caterpillar 775G dump truck is widely used on mine sites across the world. Built with a Caterpillar C27 diesel engine, the Cat 775G has improved fuel efficiency and emits up to 9% less CO2 emissions than the 775F model.

This high-performing off-road dump truck operates at 128dBA (unattenuated) with increased speeds and enhanced traction control.

Reducing the dynamic machine noise output provides further effective operation of the Cat 775G; by facilitating an increase in operating hours and resource recovery, carbon emissions and stakeholder satisfaction.

Minetek were commissioned to design and manufacture a turn-key sound attenuation solution for the Caterpillar 775G dump truck. The goal of this project was to reduce the machine’s operating noise down to the strict mine noise level, without compromising its operating capacity or adding excess weight to the machine. This sound reduction solution was also designed to provide easy access for routine maintenance and servicing.

Minetek is internationally recognised among OEMs and mining operators as a producer of the world’s quietest mining sound attenuation kids. Our sound attenuation solutions are engineered to maintain productivity and minimise the impact on operators and maintenance teams. Minetek’s modular sound suppression kits are available for mining trucks, excavators, dozers, loaders and drills, with certified install teams available globally.
