The SB 52 is the smallest model in Atlas Copco’s new generation of SB hydraulic breaker attachments. Designed for small carriers in the 1,540- to 2,650-pound weight class, the 121-pound SB 52 offers an improved design that enhances operator visibility and allows for easy positioning and operation in confined spaces. The breaker attachment delivers a maximum impact rate of 1,800 blows per minute, 20-percent more than its predecessor. The breaker operates at a pressure range of 1,450 to 2,180 psi and requires hydraulic oil flow of 3.2 to 8.5 gpm.
