IEEP’s unique design and development allows any mining machine to be fitted with our unique sound attenuation package technology that regardless of the machine or model type, the IEEP Sound Attenuation kits will be the solution that enables mines and related industries to continue to operate whilst maintaining the integrity of the machinery.

The Caterpillar 789 is a large Mining Truck. The 789C Mining Truck is engineered for performance, designed for comfort, and built to last. Developed specifically for high production mining and hauling applications, the 789C Mining Truck keeps material moving at high volume to lower the cost-per-ton.

IEEP were commissioned to design a sound attenuation package for the Caterpillar 789C. The sound attenuation package was designed and manufactured to reduce the operating noise of the Dump Truck down below 115 dBA. With the IEEP Sound Attenuation Package installed the Caterpillar 789C operates at 113dBA. This is at 100% fan speed and under operating conditions.

The effect of this treatment has allowed the mining operations who install this kit to continue operations during noise sensitive times and in noise sensitive areas.
