Atlas Copco Introduces Compact Breaker

Atlas Copco Construction Tools LLC, West Springfield, Mass., has introduced the SB 52, the smallest model in its new generation of SB hydraulic breaker attachments.

The new breaker is designed for light demolition and landscape applications.

Suitable for small carriers in the 1,540- to 2,650-pound weight class, the 121-pound SB 52 offers an exceptional power-to-weight ration. The breaker’s slimline design enhances operator visibility and allows for easy position and operation in confined spaces such as inside buildings or in narrow trenches.

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

Thanks to a replaceable floating bushing and even fewer working parts, the SB 52 is easier to service than the previous model. A longer bushing length provides maximum tool guidance to reduce off-line movement and subsequent tool wear. The breaker also features a wide shank diameter to withstand bending stress and operator abuse.

Additionally, vibrations and noise emissions have been significantly reduced due to a new hammer mechanism with recoil dampening.
