Komatsu V-series breakers designed for variety of demo applications

Depending on the application’s hardness, V-series breakers automatically select the best piston stroke length and speed

Komatsu’s new JMHB-V breakers are designed to help customers achieve maximum impact energy in a variety of demolition applications.

Designed and tested for compatibility with Komatsu excavators from the PC210 up to the PC490, Komatsu’s new 100% hydraulic-fired V-series breakers modulate their impact force and frequency with up to 16 working positions to match most applications’ requirements.

Designed to help maximize productivity while helping lower cost per ton, the breakers 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.

Komatsu’s V-series 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. The completely enclosed sound-dampening housings are designed to reduce the amount of noise generated when compared to open style breakers, to offer customers a solution to addressing noise ordinances in urban applications.

To support regular maintenance of breakers, inspection kits are included with gauges to measure wear on all critical components. Additionally, these breakers are backed by the Komatsu North America Attachment Division, a dedicated hydraulic attachments sales and service team that supports Komatsu distributors. These specialists are factory-trained and experienced with installation, operation, service and rebuilds.
