NoiseShield for Dino DC series

NoiseShield-DC, is a simple, compact solution for the smaller, cabin-less Dino™ DC410Ri and DC420Ri(*) drill rigs (14 kW rock drill, recommended hole diameter 51–76 mm / 2”–3”) that excel in urban worksites.

Description

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 neighborly relations with local communities. The new solutions introduced by Sandvik are not only beneficial to the surrounding areas, they also reduce operators’ and worksite personnel’s exposure to harmful noise levels, thereby offering a more comfortable working environment.

NoiseShield-DC, is a simple, compact solution for the smaller, cabin-less Dino™ DC410Ri and DC420Ri(*) drill rigs (14 kW rock drill, recommended hole diameter 51–76 mm / 2”–3”) that excel in urban worksites. While not fully enclosed, NoiseShield-DC offers up to a −7.5 dB reduction in A-weighted sound pressure by directing the drilling noise upwards through an open top, away from the operator and surrounding areas. This reduction translates to an 82 percent mitigation in noise pressure within a 16-meter radius of the drill rig.

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.
