Atlas Copco introduces its new high-performance hydraulic breaker, the SB 702, designed for a wide range of gardening, landscaping, construction and demolition jobs. The company combined intensive research, innovative product design and knowledge of breaker technology to develop a breaker that offers lower fuel consumption, lower vibrations and less noise than previous models.
A unique feature of the SB 702 is its solid body, a feature that no other breaker in the 700 kg class has, according to its maker. The one-piece housing construction makes the SB 702 compact and easy to handle. The percussion mechanism and guide system are integrated into a single block of steel, eliminating the need for side bolts. The integrated, maintenance-free accumulator is easily accessible yet well-protected from bangs and knocks.
The SB 702 works with a wide oil flow range and can therefore be installed on a broad variety of carriers. In case of hydraulic overload, the SB 702 is protected by an integrated protection valve that prevents damage to the breaker and helps avoid downtime.
Double tool retainer bars minimize stress and wear on the working tools of the SB 702 and changing them is made easy thanks to the patented retainer bar lock system. In addition, the floating lower bushing can be replaced by the operator on-site with standard hand tools.
Thanks to energy recovery, the SB 702 provides much higher percussive performance than previous models. While the impact energy remains constant, the breaker increases the blow frequency, which increases percussive performance. This, in turn, increases efficiency, which enables higher productivity with lower fuel consumption. Energy recovery also helps to absorb recoil, which means less wear and tear on the carrier and a higher level of comfort for the operator.
