Komatsu Hydraulic Breakers

Komatsu hydraulic rock breakers are specifically matched to our own excavator range covering utility through to heavy construction machines. 

 

Komatsu breakers bring industry-leading rock breaking technology to our entire construction excavator range – fully backed by the industry’s best service and support network.

 

The range of new Komatsu breakers available in Australia, which have operating weights from 90 kg to 3500 kg, have been designed to suit Komatsu excavators from the PC18 through to the PC450LC-8.

 

This range includes the Komatsu Heavy line of breakers, available as both a two-speed option and as a fully variable speed version.

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

 

Komatsu’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.

 

Now with the Komatsu Breaker range, we can 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.

Komatsu breakers offer several unique advantages, including a variable frequency and energy system on selected models for higher productivity and lower maintenance costs.

 

Komatsu Breakers’ design engineers understand that percussion efficiency is the key – not heavier breaker weight, which simply results in increased carrier fuel consumption.

 

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

 

Komatsu breakers offer the industry’s highest percussion efficiency, with their lower input power requirements resulting in better fuel efficiency.

In addition, higher output power means greater productivity in fractured and semi-fractured rock.
All Komatsu breakers incorporate a back pressure-tolerant design, blank firing protection, over-flow protection and a fully enclosed nitrogen filled accumulator.

 

Combined with the low operating costs benefits of Komatsu’s excavator range, 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.
