Used in a variety of rock and concrete demolition applications from scaling a tunnel, to running a pedestal-boom on a quarry, or tearing out reinforced concrete abutments, breakers are essential tools. Designed and tested for compatibility with Komatsu excavators from the PC210 up to the PC490, Komatsu’s new JMHB-V breaker series helps customers achieve excellent impact energy and performance in a variety of demolition applications.

High productivity and efficiency

With minimal wasted energy and subsequent higher operating efficiency, Komatsu’s 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 innovative energy-saving recovery valve that recuperates energy to drive efficiency.

Fully variable technology

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.

Valuable standard features

To help owners get more from their investment, Komatsu’s V-series breakers have several valuable 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.

Control vibration and noise

For greater operator comfort, suspensions with rubber/poly components help absorb impact and reduce vibrations through the boom. The completely enclosed sound-dampening housings reduce the amount of noise generated when compared to open style breakers, to offer customers a solution to addressing noise ordinances in urban applications.

Equipped for dependability

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.

Breakers are a flexible and crucial attachment used for a wide variety of jobs, including tunneling, trenching, foundation removal, dredging, bridge demolition, quarry excavation, mining, and more. To meet growing demand in North America, Komatsu is expanding its product line of hydraulic breakers. Designed and tested for compatibility with Komatsu excavators from the PC78 up to the PC490, the high-percussion efficiency and unique variable energy technology of these breakers are built to provide high production in multiple applications.

To protect the breaker, carrier, and operator, Komatsu has several built-in several features and benefits. The breakers have an accumulator that eliminates hydraulic pump cavitation to prevent flow surges back to the carrier hydraulic tank. By recycling high-pressure oil internally, more energy is allowed with a lower flow, which also works to reduce hydraulic pressure spikes and protect the carrier’s hydraulic system.

JTHB-G line of breakers

Easy to maintain with only two moving parts, the JTHB-G line utilizes a hybrid design of hydraulic flow and pressure along with a nitrogen-filled chamber that provides striking energy. The patented tie-rod design is engineered for durability in tough rock and concrete applications.

Adding to longevity and durability, blank firing protection is standard and includes a hydraulic cushion at the base of the cylinder, to reduce metal-to-metal contact. Larger models feature special key slot dampers that help reduce vibration to the excavator, adding to operator comfort.

The simple design of the JTHB-G hydraulic breakers translates to reduced maintenance and fewer parts to buy, which helps lower equipment-running costs. A one-year warranty comes with all G-series breakers and also applies to breakers used for mining and quarry applications.

JMHB-H line of breakers

Compact yet powerful, the JMHB-H attachments are accumulator-type hydraulic breakers for a variety of rock and concrete demolition applications. Unlike gas-fired breakers, the JMHB-H series does not require a nitrogen recharge. Rather, they come equipped with blank firing protection to help prevent piston movement via a hydraulic brake.

For consistent impact power in a variety of environments, sound dampening housings help assure compliance with noise ordinances, even in urban applications. The breaker protects itself with a patented pressure regulator valve to prevent overflow, and its dampening system helps prevent damage to excavator booms and housing cracks.

To enable the use of more powerful breakers on smaller excavators, a single power cell eliminates heavy tie rods to provide a better weight-to-power ratio on compact models, while the mounted automatic lubrication feature helps protect against dust and debris. Similar to the G-series, all H-series breakers come with a one-year warranty.
