Noiseguard - DXI for Ranger DXI series

Many contractors and quarries face increasingly restrictive noise limits, particularly in urban areas. Effective solutions are necessary to cut out harmful noise to improve work safety and to maintain neighbourly relations with local communities. The new solutions introduced by Sandvik are not only beneficial to the surrounding areas, they also reduce operators’ and work-site personnel’s exposure to harmful noise levels, thereby offering a more comfortable working environment.

NoiseGuard-DXi is a fully enclosed structure that provides up to −12.9 dB noise reduction in A-weighted sound pressure within a 16-meter radius of the rig. In this measuring distance, the noise reduction compared to unmitigated sound pressure is up to 95 percent. The NoiseGuard-DXi option comes with a camera system that provides visually aided drilling when the structure doors are closed. Additionally, it has an innovative single-bolt dismantling design for fast and easy maintenance on the feed system.

Requirements to limit noise from drilling machinery stem from several international and national sources, such as EU directives, various safety standards, occupational health and safety legislation and environmental regulations. The measurements above represent the A-weighted sound pressure (LpAd) levels according to the EN 16228-1 safety standard, which applies the methods standardized in SFS EN ISO 3744:2010 for determining the sound power level of a noise source.
