Komatsu announces rock breaker range
Hydraulic breakers designed to work with excavators from one to 85 tonnesKomatsu has launched its very own range of hydraulic rock breakers with operating weights from 65kg to 5589kg, designed to fit its own excavator series.
The Komatsu-branded rock breakers are suitable to use with Komatsu’s mini excavators (0.7 to 7.5 tonnes), medium sized excavators (7.5 to 20 tonnes) and large excavators (20 to 90 tonnes).
The rock breakers are available as both a two-speed option as well as a fully variable speed version.
The fully variable speed version automatically changes its frequency to different conditions or material hardness for increased productivity across varying applications, Komatsu said.
According to Komatsu’s General Manager for Construction & Utility Marketing, Charles Wheeldon, the company’s new breaker range brings 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 Komatsu breaker range offered several unique advantages, including the variable frequency and energy system on selected models for higher productivity and lower maintenance costs.
“Our design engineers understand that percussion efficiency is the key – not heavier breaker weight, which simply results in increased carrier fuel consumption,” he said.
“Our variable speed breaker design provides greater hydraulic efficiency, further enhanced with our energy recovery and regulation systems.”
Wheeldon said Komatsu’s breakers offer the industry’s highest percussion efficiency, as the lower input power requirements mean better fuel efficiency.
“As well, all Komatsu breakers incorporate a back pressure-tolerant design, blank firing protection, over-flow protection and a fully enclosed nitrogen filled accumulator,” Wheeldon said.
“Combined with the low operating cost benefits of our excavator range, this means a Komatsu combined excavator/breaker package offers major benefits, including better productivity and performance, reduced downtime, lower cost per hour, and the industry’s leading service and support network.”
Komatsu breakers are available with a range of tools for different applications, including chisel, moil point, pyramid point and blunt tool.
