Liebherr R9800
Case Study.
Minetek were commissioned to design and manufacture the first sound attenuation package in the world for the Liebherr R9800 mining excavator. The goal of the project was to reduce the machine's operating noise down to the site noise level without compromising the machine's operating capacity, adding excess weight to the machine, or restricting access for routine maintenance and servicing.
With the Sound Attenuation Package installed, the Liebherr R9800
operates at the incredibly low noise output of 114dBA - a 12dBA sound reduction that allowed our Hunter Valley mining client to operate the machine 1000m closer to the boundary/sound receiver.
