Designed for long life
See your investment protected with a mounted automatic lubrication feature that guards against contamination caused by dust and debris, promoting a long breaker life. Standard on many models.
Equipped for dependability
You'll be equipped to keep your breakers performing optimally with an inspection kit that can assess routine maintenance needs, standard with all models.
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.
Adaptable and versatile
Versatility to adapt to various rock types with two working positions to provide the appropriate frequency and energy per blow.
Noise reduction
Completely enclosed sound-dampening housings reduce noise generated vs. open style breakers.
Powerful compact range
Bring plenty of force to smaller excavators with compact models that use a single power cell without heavy tie rods, improving weight-to-power ratio.
Standard features
You get valuable features built right into your investment with standard features, such as automatic greasing, advanced blank firing protection, swivel hose couplings and heavy-duty housing.
