Komatsu unveils latest hydraulic rock breakers

Komatsu has released a range of hydraulic breakers matched to fit its own excavators and designed to work with machines from less than one tonne to more than 85 tonnes.

The range of breakers have operating weights from 65 kilograms to 5589 kilograms, making them suited for mini, medium sized and large excavators.

Komatsu’s heavy range of breakers are available as both a two-speed option and a fully variable speed version.

The fully variable speed versions automatically change their frequency to different conditions or material hardness which increases productivity across varying applications.

Komatsu’s general manager, construction and utility marketing, Charles Wheeldon, said the company’s new breaker range brought industry-leading rock breaking technology to its entire construction excavator range.

“For many years, Komatsu has been recognised as offering the industry’s best range of excavators, in terms of performance, productivity, reliability, durability and cost of ownership,” he said.

“Now we are delighted to be able to offer a matched line of breakers, designed to work with our own excavator line, and backed by the full Komatsu support network across Australia, New Zealand and New Caledonia.”

Wheeldon said the new breaker range offers several unique advantages, including the variable frequency and energy system on selected models for higher productivity and lower maintenance costs.

“Our variable speed breaker design provides greater hydraulic efficiency, further enhanced with our energy recovery and regulation systems,” he said.

“Komatsu breakers offer the industry’s highest percussion efficiency, with their lower input power requirements resulting in better fuel efficiency, higher output power means greater productivity in fractured and semi-fractured rock.”

The Komatsu breakers are available with a range of tools for different applications, including chisel, moil point, pyramid point and blunt tool.
