Three years ago Atlas Copco launched the first of the new generation of solid body breakers based on a new manufacturing method and new body design, and last year it sold more than 10,000 small breakers in the 50 to 550kg class. Atlas Copco SB breakers are used for road work, trenching, general demolition, plus primary and secondary rock breaking, and the company is now launching the mid-range model, the SB 302, for excavators of up to 9tonnes.
