A newly upgraded Silence Kit for Atlas Copco’s SmartROC T35 and T40 surface drill rigs is available. The new kit, developed in cooperation with experienced users, reduces the noise generated from the feed by an additional 2dB(A). Key improvements from the original kit include a double layer of noise absorbent material together with an upgraded aluminum chassis that has greater resistance to drill rod vibration. Without the silence kit, the noise level of the SmartROC T35 and T40 is 127 dB(A) at peak power. With the upgraded silence kit added, tests show that the noise level drops to 115 dB(A), providing an improved working environment and meeting current demands for lower noise levels, states the company. Furthermore, the new Silence Kit has four access hatches, with a fifth at the very top of the feed. These can be opened two at a time at the touch of a button. The kit also has an updated lighting system.
