Atlas Copco has introduced the largest model in its new generation of SB hydraulic breakers—the SB 552. The breaker is designed for a multitude of applications, including demolition, road construction, building renovation, foundation work, trenching, landscaping and secondary breaking. Weighs 1,149 pounds and is designed for carriers in the 9 to 15 metric ton weight class. The SB 552 delivers a maximum impact rate of 1,080 blows per minute and required oil flow of 17.2 to 30.4 gallons per minute at a pressure range of 1,450 to 2,180 psi. The SB 552 has fewer parts than competitive models and it does not use side bolts and separate components from the front head, cylinder and back head. Additionally, the breaker’s slimline design allows for better operator visibility and easy positioning in confined spaces. It also features a built-in pressure relief valve as standard equipment to protect the breaker from exceeding recommended operating pressure.
