Chicago Pneumatic is increasing the availability of its RX
series
K
erala-based granite q
uarry, National Granite andHollowBricks, is usingChicago
Pneumatic CP1150 andRX
22 hydraulic breakers aswell as aCPP60E compressor
for breaking and drillingwork.
As part of the q
ua rrying process, over-sized boulders blasted from the q
uarry face need
to undergo secondary breaking to fit into crushers. National Granite turned toChicago
Pneumatic and purchased its first CP1150
rig-mountedmedium hydraulic breaker in
2006 after an on-site demonstration. The
RX
22 followed by a few years later.
Thanks to their design, featuring
limited components and only twomoving
parts, Chicago Pneumatic’
smedium
hydraulic breakers are, according to
themanufacturer, built to ensure high
reliability and endurance.
The company is expanding the availability
of theRX
rangeworldwide, with a push
intoChina.
AndrewCope, vice president of business
development for Chicago Pneumatic
Construction Eq
uipment, said, “
O
ur RX
breakers represent a cost-effective solution
for those seeking to invest in durable and
robustly built eq
uipment that will perform
in the toughest environments. Tools of
this kindwill be vital to this country’
s
construction industry.”
Meanwhile, Sandvik has introduced four new Rammer
branded breakers - three new small units and the 5011 heavy
duty hammer.
The new small breakers are the 255, 355 and 455 that plug
a gap in the company’s line up and are intended for carriers
from 1.2 tonnes to 5.2 tonnes. A key feature is the constant
blow energy operating principle, which Sandvik saysmaximises
productivity and profitability.
Powerful impact
Meanwhile UK-based demolition company AR Demolition
used anew5011 for to clear the siteof the formerNorthampton
Chronicle newspaper offices. The hammer was mounted on a
Volvo EC460L excavator, delivering a high power/low impact
rate for the application of concrete breaking.
AR Demolition’s managing director, Richard Dolman,
described the site as a “potential nightmare” in terms of the
challenge of clearing heavily-concreted areas. He said, “We are
clearing the site in advanceof the constructionof anew store for
a major supermarket chain and we cannot afford delays. So we
chose a breaker that was as reliable as it is powerful.”
Sandvik alsomarkets breakers under the Bretec brand, which
is designed to be a mid-level product. The latest additions to
the C-series range are theM17C and L20C, which incorporate
a number of new features and updates over the M17 and L20
models they replace.
Designed for carriers in the 15 tonne to 23 tonnes and 20
tonnes to 29 tonnes weight classes, the M17C and L20C
models boast operating weights of 1.2 tonnes and 1.6 tonnes
respectively. Impact rates range from 280 to 760 blows per
minute on theM17C, and from 390 to 700 blows per minute
on the L20C.
