to increase strike power, as well as a
blank-fire protection system.
In addition, the 501 NG hydraulic
breaker features an upper and lower
suspension system that has beendesigned
to extend the carrier’s work life by
absorbing harmful vibrations and stress
waves.
Optional features include an air
pressurisation kit for underwater applications, as well as
an automatic, cradle-mounted grease station that delivers
continuous oil flow, reducing bushing and tool wear.
The company has also opened a remanufacturing facility
BREAKERS
New features
in Lake City, Georgia, US, to address what it said is growing
demand for remanufactured hydraulic breakers.
“Our new facility in Lake City provides us with greater
capacity and control over the remanufacturing process,” said
Gaetan Julien, product support manager for Montabert North
America. “Customers now have the option to purchase like-
new equipment – or send their equipment for repair – at a
significantly lower cost.”
Increased productivity
At the larger end of the breaker scale, the latest unit from
Dehaco’s Ibex range is for excavators weighing up to 46
tonnes. A key feature is the advanced hydraulic circuit on the
range, which provides increased flow to the valve and piston,
resulting in faster cycle times, increased penetration and more
productivity than previousmodels.
All this shows that while hydraulic breakers have been around
for 50 years or more, there is plenty of development going on
into newmodels which are simpler to maintain, more reliable
in operation, and in some cases which have better performance
through the capture of waste energy.
