The company says the new breakers are lightweight but very durable, with increased impact energy due to a nitrogen-charged back head that enables energy transfer to where it is most required.
The slim design of the breaker is intended to enable easy accessibility in demolition and trench work while providing high levels of efficiency and productivity in quarrying applications. The top damper is designed to reduce noise and vibration, leading to a less intrusive and more environmentally friendly job site while reducing operator fatigue and machine wear and tear.
The serviceable floating rod seal minimises dust intake, which Hitachi says results in an extended lifetime.
The mono-block cylinder with a replaceable cylinder liner has been developed to reduce the number of parts in the attachment. The front head design includes a replaceable thrust bushing for extended service life, and auto lube is fitted as standard on model FXJ125 onwards.
