MODERN MINING

T
he Cat 6015B has the flexibility
to work in heavy construction,
quarry/aggregate, and small to
medium size mining applica-
tions, says Bongani Sibeko, Prod-
uct Manager: Mining at Barloworld Equip-
ment. “This machine will also help contract
miners to produce more material at less
cost, meet production targets and
maximise profitability.
“The Cat 6015B builds on the
legacy of the popular Cat 5110B
shovel, which has always been
known as a robust and reliable
digging machine.
“The 6015B has an operating
weight of 140 tonnes with the
most powerful engine in its class at 606 kW,”
continues Sibeko. “The standard heavy duty
bucket is also one of the largest in this machine
class with a capacity of 8,1 m³. The combination
of powerful engine and bigger bucket provides
faster cycles and one pass-match advantage
with Cat 773, 775 and 777 trucks over compet-
ing machines with standard buckets.”
He adds that the extensive use of Cat compo-
nents such as the HEX cab, D11 track links and
robust 5110B mining linkage assure the quality
of the Cat 6015B.
Efficiency
The 6015B is powered by a Cat C27 ACERT™
engine rated at 813 horsepower that gives it the
edge in digging power and cycle times. The
8,1 m³ bucket, using Cat C70 hammerless GET,
is optimally suited to fill a Cat 773 truck in four
passes, a 775 in five passes, and a 777 in seven
passes. Manufactured at Caterpillar factories in
Dortmund, Germany, and Batam, Indonesia, the
Cat 6015B is currently available only in a back-
hoe configuration.
The Cat 6015B is both powerful and efficient.
In controlled tests, this machine has delivered
a strong production advantage in pure tonnes
produced over similar specification competi-
tors, coupled with better fuel efficiency per
tonne produced.
Fuel efficiency is boosted by several specific
features, including Caterpillar’s proprietary
integrated engine control technologies, a
boom float feature that regenerates boom oil
for reduced engine demand, an oil cooling
system independent of engine cooling, and
regeneration of swing energy via a closed-loop
swing system.
Cat automatic flow proportioning technol-
ogy creates more efficient hydraulic pump
utilisation, with less energy loss and more fuel
savings. Exclusive Cat Proportional Priority
Pressure Compensating technology ensures
that hydraulic flow is proportional according
to demands so that individual boom, stick and
bucket functions are automatically prioritised
during simultaneous operations. This aids
smooth, efficient operation and controllability.

Barloworld Equipment prides itself on its ability to sell
and support the earthmoving requirements of customers
across the spectrumwith a comprehensive range of Cat®
load and haul combinations. Caterpillar’s new 6015B
hydraulic shovel illustrates this strategy, coming into the
Southern African market as a loader that comfortably fits
the gap between legacy Cat hydraulic excavators and the
larger Cat mining shovels.
