Atlas Copco unveils new compact breaker

The SB 52 may be the smallest model in the new generation of SB hydraulic breakers, but this lightweight packs a punch. At just 121 pounds the SB 52 has an improved power-to-weight ratio, compared with previous models. The slim design of the SB 52 allows the operator enhanced visibility, positioning and operation in confined spaces.

Delivering a maximum impact rate of 1,800 blows a minute, the SB 52 is 20-percent faster than its predecessor. The breaker operates at a pressure range of 1,450 to 2,180 psi and requires 3.2 to 8.5 gallons of hydraulic oil flow per minute.

The solid body, one-piece cast iron design of the Atlas Copco SB 52 encases all vital parts of the compact breaker and provides strength and reliability while reducing vibrations and noise emissions by using a new hammer mechanism with recoil dampening.
