Atlas Copco’s SB 302 offers a high power-to-weigh ratio and delivers a maximum impact rate of 1,380 blows per minute, a 48-percent increase over its predecessor. The 670-pound breaker is suitable for carriers in the 4.5- to 9-metric-ton weight class and requires oil flow of 13.2 to 21.9 gallons per minute at a pressure range of 1,450 to 2,175 psi.
The solid body concept of the SB range features a one-piece design that contains all integral parts in the same iron alloy casting for added strength. The breaker’s slim design allows for better operator visibility positioning in confined spaces. A new hammer mechanism with recoil dampening that reduces vibrations by up to 53 percent compared with previous SB models. Noise levels have also been lowered by 5 dB(A).
