Komatsu JMHB-V Series Breakers

Nov. 19, 2021

Komatsu’s JMHB-V Series breakers are designed and tested for the company’s PC210 through PC490 excavators.

The 100-percent hydraulic-fired V Series breakers modulate their impact force and frequency with up to 16 working positions to match most application’s requirements. They are also fitted with an 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, according to the company.

Standard features include automatic greasing, advanced blank firing protection, swivel hose couplings, and heavy-duty housing.
