WESTFIELD, Mass. — Atlas Copco Construction Tools LLC introduces the SB 302, the first mid-range addition to the company’s new generation of SB hydraulic breaker attachments. The breaker is ideal for demolition, road construction, trenching, landscaping and secondary breaking.
Thanks to a higher efficiency design, the SB 302 offers a high power-to-weigh ratio and delivers a maximum impact rate of 1,380 blows per minute, a 48-percent increase over its predecessor. The 670-pound breaker is suitable for carriers in the 4.5 to 9 metric ton weight class and requires oil flow of 13.2 to 21.9 gallons per minute at a pressure range of 1,450 to 2,175 psi.
The unique solid body concept of the SB range features a one-piece design that contains all integral parts in the same iron alloy casting for exceptional strength and reliability. The SB 302 has fewer parts than competitive models as it does not utilize side bolts and separate components for the front head, cylinder and back head.
The breaker’s slimline design allows for better operator visibility and easy positioning in confined spaces such as during indoor demolition and narrow trenching. A new hammer mechanism with recoil dampening that reduces vibrations by up to 53-percent compared with previous SB models, helping to ease stress on man and machine. Noise levels have also been lowered by 5 dB(A).
Routine maintenance of the SB 302 is simple thanks to a limited number of moving parts and a replaceable floating bushing. The bushing’s increased length provides maximum tool guidance to reduce off-line movement and subsequent tool wear.
For added equipment reliability, the SB 302 features a built-in pressure relief valve as standard equipment to protect the breaker from exceeding recommended operating pressure. The accumulator has been cast into the main body of the breaker for a more rugged design, and uses a new charge valve, which is now flush with the accumulator cover for optimum protection. These new features eliminate the step of unbolting the accumulator when re-sealing the breaker and the need for constant charging of the accumulator. The SB 302 is covered by a limited three-year warranty.
