with expanded electronic control,
automatic
traction
control,
automatic retarder control, hill
assist andwaiting brake systems.
Among other features is an
optional payload weighing system.
This is designed to deliver lower
operating cost through reduced
cycle times, fuel savings and easing
operator’s workloads.
The ranges includes the 36 ton
(32.7 tonne) capacity 735C, 42 ton
(38 tonne) 740C EJ ejector model,
and45.2 ton (41 tonne) 745C.The
745C’s 1.7-ton (1.5 tonne) capacity
increase over its predecessor
represents a new size class of ADT
forCaterpillar.
Julien Balardelle, Caterpillar
product specialist, said, “Our new
745C is going tobe a game-changer
within the 40 ton articulated truck
class. It is not just a replacement for
our successful 740B series, it is a
completely newmachine.
“Some of its top features include
a new ACERT C18 engine and a
brandnew transmission.”
The 735C’s Cat C15 ACERT
engine is rated at 337 kW, while
the C18 ACERT engine used in
the 740CEJ and745Chas a higher
output, rated at 381 kW.
The 740C EJ ejector model,
which combines the 745C’s tractor
with a horizontal discharge body,
provides added versatility in having
the ability to unload material to
uniform depths while travelling
at speed. This potentially reduces
the need for on-site spreading
equipment.
Another advantage is the ability
to discharge loads in places where
it would be difficult or dangerous
to raise the body - soft underfoot
conditions, on slopes or where
there are overhead obstructions, for
example.
Among the company’s new
excavators is the 336F XE hybrid.
This features a235kWTier 4Final/
Stage IV engine and is capable
of fuel savings of up to 20% over
standardmodels.
It is available in L and LN
undercarriage configurations, and
includes a factory-installed payload
management
system,
which
Caterpillar said was unique within
the excavator segment.
Fuel savings are achieved through
the engine output being matched
to the loads on the machine,
complemented by an intelligent
hydraulic valve which delivers oil
flow as it is required. In addition,
waste energy from the braking of
swing movements is captured by
hydraulic accumulators, and re-
used in other hydraulic functions.
Another new model in the range
is the 313F L GC excavator. Its
52 kW engine achieves EU Stage
IIIB emissions standards, rather
than Stage IV regulations, which
only apply to 56 kW engines and
above.
With an operating weight of
13.3 tonnes, it has high-power and
economyoperatingmodes, aswell as
integrated Cat Connect technology
for improvedfleetmanagement.
Dozer
Caterpillar’s latest dozer, the D6N,
is said to deliver up to 15% savings
in fuel over previous models thanks
to a newdirect-drive transmission.
There is a lock-up clutch that
allows the 16.5 tonne machine
to carry loads in direct drive for
optimum fuel efficiency, while the
auto shift system allows operators
to select the optimum ground speed
for the load beingmoved.
Productivity gains in typical
applications are estimated at up to
10%, compared with the previous
model.
The dozer is equipped with
Cat Connect to help manage
construction tasks. Its grade systems
use digital design data, in-cab
guidance, and automatic blade
control, which help achieve greater
accuracy for operators.
It is powered by a 124 kW Cat
C7.1 ACERT engine which meets
Tier 4 Final/Stage IV emission
standards.
The 313F L GC excavator
features Cat Connect
monitoring systems.
The D6N is Caterpillar’s latest dozer release.
Caterpillar’s 938M has been given a
power boost for greater road speed.
