Caterpillar’s new Cat 986H large
wheel loader delivers with lowest cost per
tonne production in varied sectors ranging
from opencast mining and underground
loading to granite block handling, steel mill
applications and quarrying.
The first Cat 986H models rolled out of
Caterpillar’s Tongzhou factory in China
during the fourth quarter of 2013 and
are now available for deployment in the
southern African market.
“The development of the Cat 986H comes
in response to global customer demand
for a purpose-built machine that fills the
gap between the Cat 980H and Cat 988H,
with a major emphasis on simplified and
safe operation, ease of maintenance and
improved bottom line operating margins;
key considerations in today’s mining
environment, especially when it comes
to diesel fuel consumption,” explains
Barloworld Equipment group product
application specialist, Brandon Stonefield.

loading in a new class
(Barloworld Equipment is the Cat dealer for
southern Africa.)
In the field, the Cat 986H has a rated
payload of 10 tonnes in standard lift
and 9,5 tonnes in high lift specification
when equipped with a rock bucket, with
a breakout force of 328 kN. In turn, the
general purpose bucket (standard lift) has a
12 tonnes rated capacity, and 10 tonnes in
high lift. (By definition, rated payload is the
material weight in the bucket that the loader
is designed to carry, excluding the weight of
the bucket itself, GET and wear material.)
Equipped with standard lift configuration,
the Cat 986H is a four pass match for the
Cat 740B articulated truck and Cat 770G
off-highway derivative (the approximate
payload in both instances being around 39
tonnes). In turn, and equipped with a high lift
linkage, the Cat 986H will load a Cat 772G
(47,7 tonnes) and 773G (56 tonnes) rigid
truck in five and six passes, respectively.
At the heart of the Cat 986H is its six cylinder
turbocharged Cat C15 engine, generating a
net output (ISO 9249) of 305 kW. This is
one of the most fuel efficient engines in
its class, underscored by competitive tests
conducted by Caterpillar. During a recent
controlled truck loading study, for example,
the Cat 986H burned between 30 and
35 litres per hour, in the process loading
around 650 tonnes during system
production.
The Cat 986H comes standard with a
6,1m³ Performance Series rock bucket,
designed to maximise material retention
and minimise digging time, achieving
a remarkable 100 to 115% fill factor,
depending on the ground engaging tools
(GET) installed, which in this case is the
Cat K110 tip series (in either general duty
or penetration specification).
