The new Worksite Pro hydraulic breakers from John Deere feature a solid one-piece design that does not need side bolts, which results in a tough breaker that is suited to heavy-duty applications. The breakers can be used with skid-steer loaders, compact-track loaders and compact excavators. The low-pressure, nitrogen-charged design cushions operators from recoil, while the narrow overall shape allows these breakers to work in tight quarters and crowded jobsites. With few seals and moving parts, and no special tools necessary, these breakers are engineered to offer durability and simplified maintenance.

The Bobcat HB1180 hydraulic breaker attachment has a new internal design with fewer moving parts, which reduces overall service time. Another major advancement, the company says, is the auto power feature, which is an automatic pressure regulator that ensures maximum performance of the hydraulic breaker, regardless of tool carrier hydraulic flow variations or changes in outdoor temperature. This means that each hydraulic breaker attachment delivers a high performance impact blow within a vast flow range of carriers.

The BH 24 breakers from Wacker are designed to produce more power and reduce hand/arm vibration. The gasoline-powered BH 24 features an optimized percussion system. The piston and striker have a reconfigured shape that reduces the weight and increases the velocity to make for a harder hitting breaker. Also contributing to the reduced vibration is Wacker's patented vibration damping protective housing.

The medium range Ingersoll Rand Tramac hydraulic breakers are designed for use on large backhoe loaders and medium-size excavators to effectively break oversize boulders, excavate and demolish concrete up to 6-feet thick. The breakers also feature a patented energy recovery valve that recycles recoil energy and adds it to the next blow. A progressive start system creates a small niche in the material, preventing the breaker from sliding by applying the first few blows with low energy before full power is applied.
