Atlas Copco’s SB 452 breaker for excavators of up to 13 tons are used for road work, trenching, general demolition, and landscaping. One of the most important features in the new design is the floating bushing which makes service and maintenance really easy. The new SB 452 brings many advantages; the single blow impact energy has increased by more than 12 percent compared to the previous model which results in higher performance and breaking power. And the new body design generates lower vibrations and less noise to meet the high demand of our customers. A solid body breaker is machined from a single block of steel. This method provides a number of benefits, such as no side or head bolts and a unique resistance to bending forces and operator abuse. Another advantage is fewer parts and less maintenance.The slim design of the SB 452 makes positioning easy.
