Designed and tested for compatibility with Komatsu excavators from the PC210 up to the PC490, the JMHB-V Breaker Series helps achieve excellent impact energy and performance in a variety of demolition applications.
With minimal wasted energy and subsequent higher operating efficiency, the 100% hydraulic-fired V-series breakers modulate their impact force and frequency with up to 16 working positions to match most application requirements. The breakers are also fitted with an innovative energy-saving recovery valve that recuperates energy to drive efficiency.
Depending on the application’s hardness, V-series breakers automatically select the best piston stroke length and speed. By adjusting to either hard material, with long and powerful strokes, or to softer material, with shorter, faster strokes, the breakers can achieve high production output with little wasted impact energy.
The breakers have several standard features, including automatic greasing, advanced blank firing protection, swivel hose couplings, and heavy-duty housing. The shock-dampening systems in the form of upper and lower suspensions help reduce the risk of cracking excavator booms and breaker housings, while the mounted standard automatic lubrication feature helps guard against contamination caused by dust and debris.
For greater operator comfort, suspensions with rubber/poly components help absorb impact and reduce vibrations through the boom. To support regular maintenance, inspection kits are included with gauges to measure wear on all critical components.
