Hydraulic breaking equipment for producers to consider

Komatsu’s JMHB-H attachments are accumulator-type hydraulic breakers for a variety of rock and concrete demolition uses. Unlike gas-fired breakers, Komatsu says the JMHB-H series does not require a nitrogen recharge. They come equipped with blank-firing protection to help prevent piston movement via a hydraulic brake. The breaker protects itself with a 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, Komatsu says a single power cell eliminates heavy tie rods to provide a better weight-to-power ratio on compact models, while a mounted automatic lubrication feature helps protect against dust and debris.

TOP series hydraulic breakers are the result of decades of field experience and a longstanding record of leadership in the industry, Okada America says. Fifteen TOP series breakers ranging in energy classes from 150 ft. pounds to 15,000 ft. pounds provide a broad range of solutions for skid-steers, compact excavators, track loaders, loaders, backhoes and excavators. Okada says the TOP 100A model is ideal for use on 22,000- to 42,000-pound excavators. The model requires 29 to 35 gallons per minute at 2,030 to 2,620 psi, breaking at a rate of 550 to 710 blows per minute. Demolition of heavily reinforced concrete structures, building foundations, trench rock and oversized boulders are among the possible applications for the TOP 100A, the company adds.

Hydraulic breaking equipment for producers to consider

NPK’s hydraulic hammer line includes models available for skid-steers, backhoes and excavators of all sizes – from 1 to 108-plus metric tons – with a design that combines efficiency, reliability and serviceability. NPK says its hammers feature excellent power-to-weight ratio, a unique gas-charged piston that maximizes efficiency, a two-moving-parts design for reliability, and an anti-blank fire feature that helps eliminate dry firing for increased life. Additionally, the company’s hammer range has separate ports for air and grease, a fully sleeved design that allows for extended service life, a quick-change tool system with a single-round retainer pin, and a variety of tool configurations. NPK hydraulic hammers can also be used with the company’s pedestal breaker systems, which are designed for all types of stationary and portable crusher installations.
