The Komatsu JTHB hydraulic breaker range delivers exceptional impact energy, long lifetimes and low operating costs. What’s more, they minimise operator fatigue and environmental impact. These unique benefits are all due to an innovative blend of a simple yet efficient design and advanced “accumulator-free’ technology.

Whether you’re tearing out a reinforced concrete abutment, scaling a tunnel, or running a pedestal-boom at the quarry, Komatsu hydraulic breakers provide superior impact energy for exceptional performance in a variety of rock and concrete demolition applications. The high impact power of the JTHB Series breakers is delivered through a combination of hydraulic and nitrogen gas energy, with no need for an accumulator.
