BUSINESS CHALLENGE MINETEK were commissioned to design and manufacture the first sound attenuation package in the world for the mining excavator Liebherr R9800. The goal of this project was to reduce its operating noise down to the site noise level without compromising its operating capacity or adding excess weight to the machine. This sound reduction solution also provides easy access for routine maintenance and servicing.

With the Sound Attenuation Package installed, Liebherr All references to R9800 operates at an amazingly low noise output. MINETEK projects set an industry benchmark and noise suppression at the source is now best practice.
