February 8, 2012

Atlas Copco HB 4100 breaker is smaller than its predecessor, enabling it to be used by smaller carriers. The breaker weighs 9,039 pounds and is suitable for excavators in the 40-to-70-metric-ton range. A new covering for the retaining bar offers more protection, and the service window has been reinforced. Other features include the VibroSilenced system to protect operators against noise and vibrations; PowerAdapt, which switches off the breaker in the event of a hydraulic overload; AutoControl, for the adjustment of the blow frequency and blow energy to the hardness of the stone.
