One of Atlas Copco Construction
Technique’s longstanding mining
customers recently ordered two HB
10 000 10 t hydraulic breakers to increase
productivity at its Northern Cape open-cast
mining operation.
The mine which produces iron ore/various
grades of manganese ore has been a key
account for Atlas Copco for over 15 years.
Impressed with the high performance and
durability of the five Atlas Copco HB 7000
7 t hydraulic breakers that have been in
operation at the site for over a decade,
the mine ordered two HB 5800 (5 t) units
to meet its surface mining applications,
including rock breaking after blasting as
well as secondary breaking and crushing
of rocks before the material moves into
feeders.
According to Atlas Copco Construction
Technique Area Sales Manager, Amanda
Roets, the superior efficiency, excellent
performance and unmatched reliability of
these heavy hydraulic breakers contribute
to increased productivity and improved
production on the mine. “In addition, fea-
tures such as low noise and vibration
levels which enhance operator safety and
comfort, and the fact that they have a low
impact on the environment, played a fun-
damental role in the mine’s decision to or-
der the two 10 tonners,” says Roets. “With
these two heavy weights, which are the
first 10 t hydraulic breakers Atlas Copco
has supplied in South Africa, a total of nine
hydraulic breakers is currently operating at
the iron-ore mine.
The 10 t breakers’ larger tool diameter cre-
ates a bigger footprint and the units have a
larger handling capacity and deliver a more
powerful hit rate, meeting the mine’s re-
quirement for improved productivity.
The powerful HB range has an operating
pressure of between 160 and 180 and a
maximum hydraulic input power of 159 kW.
“Our HB range features an automatic start/
stop function for convenience and safety,”
explains Roets. The breakers have an En-
ergyRecovery system automatically util-
ising the piston recoil energy to increase
performance without additional hydraulic
input and to lower vibrations, making the
job easier and more efficient. The hydrau-
lic breakers are suitable for a wide range
of carriers including wheeled and crawler
excavators; 120 ton excavators are recom-
mended for the HB 10 000.
Atlas Copco Construction Tools are cer-
tified according to ISO 9001:2008, ISO
14001:2004, and OHSAS18001:2007.
“Our hydraulic breakers conform to the
provisions of EC Directive 2006/42/EC
(Machinery Directive) and 2000/14/EC
(Noise Directive),” says Roets.
Atlas Copco transformed the construction
and mining industries when it first intro-
duced the innovative hydraulic breakers
more than five decades ago. With end-user
productivity and total cost of ownership top
of mind, Atlas Copco has continued to re-
fine these breakers to deliver on its brand
promise of Sustainable Productivity.
