Designed and tested for compatibility with Komatsu excavators from the PC210 up to the PC490, Komatsu’s JMHB-V breakers are designed to help customers achieve excellent impact energy and performance in a variety of demolition applications.
Komatsu’s 100 per cent hydraulic-fired V-series breakers modulate their impact force and frequency with up to 16 working positions to match the requirements of most applications. Designed to help maximize productivity, the breakers are fitted with an energy-saving recovery valve that recuperates energy.
V-series breakers automatically select piston stroke length and speed, based on an application’s hardness. 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.
Standard features include 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.
Suspensions with rubber/poly components help absorb impact and reduce vibrations through the boom for operator comfort. The completely enclosed sound-dampening housings reduce the amount of noise generated when compared to open-style breakers.
To support regular maintenance of breakers, inspection kits are included with gauges to measure wear on all critical components.
