High productivity and low cost per ton
Maximize performance on the job site with breakers that fully modulate their impact force and frequency to match the application’s requirements, with minimal wasted energy and therefore a higher operating efficiency. An innovative energy recovery valve further improves this efficiency.
- 100% hydraulic fired
- Fully automatic variable speed
- A high production ratio in any application

Features and benefits
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.
Noise reduction
Completely enclosed sound-dampening housings reduce noise generated vs. open style breakers.
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.
Highly adaptable
Get plenty of performance with a breaker that’s at home in almost any application — demolition, mass excavation or secondary breaking.
High operating efficiency
You’ll see minimal wasted energy as these breakers fully modulate their impact force and frequency with up to 16 working positions to match conditions, resulting in much higher operating efficiency.
Innovative energy-saving valve
Efficiency is improved even further with an innovative valve that recuperates energy and is designed to prevent overflow.
