Caterpillar
There are several machine options
available, including Cat Slope
Indicate, which displays machine
cross-slope and main-fall on the
primarymonitor, helping operators
work more confidently on slopes.
This is linked toa stablebladeoption
that compliments an operator’s
blade-control for achieving finished
grades with less effort.
Wheeled Loaders
New wheeled loaders include the
Cat 950M and 962M, which are
fitted with Stage IV Cat C7.1
ACERT engines. They are said
to be +10% more powerful than
previous models, as well as being
up to +10% more fuel-efficient.
This has been achieved through a
redesignedhydraulic system and the
new engine.
Rated at 171kW, the new950M’s
engine produces +9% more power
than its K-Series predecessor,
and the 962M’s engine, rated at
186 kW, has +13% more power
than themodel it replacess.
The
machines’
operator
environments have been improved
with a new electro-hydraulic
joystick steering system.
Other newmodels inCaterpillar’s
‘small’ wheeled loader segment,
include the 926M, 930M and
938M. These machines have been
developed with a power boost
system for improved road speed.
The series ispoweredbyaCatC7.1
ACERT engine and range inweight
from 13.4 tonnes to 16.3 tonnes.
The
four-range
electronically
controlled hydrostatic drive now
includes operator-selected power-
train modes including a refined
torque converter mode that allows
the machine to free wheel down
hills and around grades.
Building on Caterpillar’s previous
tracked loader models, the new
963Koffer up to a 30% gain in fuel
efficiency. It also has an updated
cab and new safety features for the
comfort and convenience of the
operator, and is poweredby aTier 4
Final/Stage IV engine.
With an operating weight of
20.8 tonnes, the 963K is powered
by a twin turbo 144 kWCat C7.1
ACERT engine. Its eco mode
automatically reduces engine speed,
while maintaining selected ground
speed when the machine is under
light loads.
According to the company, fuel
savings of between 10% and 30%
are possible compared with the
previousmodel.
Compactmachines
Three compact radius Cat E2 series
mini hydraulic excavators have also
beenunveiled.
The 305E2, 305.5E2 and 308E2
cover the 5.5 tonne to 8.5 tonnes
weight ranges, andwill be produced
at Caterpillar’s new 78,968 m
2
facility inAthens, Georgia, US.
Among the series’mainupgrades is
aHighDefinitionHydraulicSystem
which provides load sensing and
flow sharing capabilities, improving
precision
and
controllability.
Standard features include automatic
twin-speed pilot controls, which
allow operators greater flexibility
and control.
The company has also released its
new M series of compact wheeled
loaders, including the906M, 907M
and908M,which featureoptimised
Z-bar loader linkage, which offer
aggressive digging power with
parallel lift.
They are powered by anEU Stage
IIIB 55 kW engine and have been
designedwithhigh-flowhydraulics.
The series, which spans the 5.6
tonnes to 7.2 tonnes weight classes,
is available with a range of work
tools and couplers.
Several backhoe loaders have
also been released. The F2 series
comprises the 427F2, 428F2,
432F2 and 434F2, which feature a
new operator environment as well
as new engines.
Cabs have been restyled with
better visibility to the loader
attachment when at full height. In
addition the range has blue-tooth
connectivity, allowing site data to
be exchanged efficiently. There is
also an in-cab telematics system in
order to track machine movement
andprovide operating statistics.
The 427F2 features a Cat 3.4B
55 kW engine with a diesel
particulate filter that complies with
Stage IIIB emissions regulations,
which is said tobe +10%more fuel-
efficient than its predecessormodel.
Its other newmodels in the series
- the 428F2, 432F2, 434F2, and
444F2, are equipped with the Cat
C4.4ACERT engine.
These range in power from
70 kW through to 74 kW and have
a selective catalytic reduction (SCR)
exhaust aftertreatment system to
meet emissions requirements.
