“Formanyyears,Komatsuhasbeen
recognised as offering the industry’s best
range of excavators, in terms of performance,
productivity, reliability, durability and cost of
ownership,” says Wheeldon.
“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 says the new Komatsu breaker range
offered several unique advantages, including
the variable frequency and energy system onselectedmodelsforhigherproductivity and
lowermaintenancecosts.
“Ourdesignengineersunderstand that

“Aswell,allKomatsubreakers incorporate
a backpressure-tolerantdesign, blank firing
protection, over-flow protection and a fully
enclosed nitrogen filled accumulator.
“Combined with the low operating costs 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,
