Ease of maintenance
Low refurbishment costs with a simpler design: only two moving parts and no rubber bladder accumulator. High-quality components add exceptional reliability.
Full compatibility
Get the benefit of versatility with breakers designed to fit any size excavator, including all Komatsu excavators and a wide variety of other makes.
Less vibration
Maximize operator ergonomics with a shock-dampening box bracket on the JTHB-G models and suspensions with rubber/poly components on the JMHB-H and -V models, which absorb impact and reduce vibrations through the boom.
