CAT Delivers More Choices

With Next-Generation Excavators, New Utility Vehicles
Three Next Generation 20-ton size
class excavators from Caterpillar
increase operating efficiency, lower
fuel and maintenance costs, and
improve operator comfort compared to previous models.
The New Cat 320 GC is designed for low- to medium-duty
applications and the 320 is for
medium- to heavy-duty. The premium 323 offers the most power and
lift capacity in the line. All three
offer unique combinations of
purpose-built features designed to
match customers' productivity and
cost targets.
Durable, efficient Cat engines
provide duty-matched power ratings from 121 to 162 horsepower,
and consume 20 to 25 percent less
fuel than the previous models. New
smart-mode operation automatically matches engine and hydraulic
power to digging conditions, optimizing both fuel consumption and
performance. In addition, engine
speed is automatically lowered
when there is no hydraulic demand.
The new cooling system
employs multiple electric fans,
which independently monitor
hydraulic oil, radiator and air-to-air

after-cooler temperatures to
deliver the exact airflow required.
Featuring a main control valve that
eliminates the need for pilot lines,
the new hydraulic system requires
20 percent less oil and lower longterm operating costs.
Reduced maintenance costs
- as much as 15 percent over
the previous series - are due to
the excavators' extended and
more synchronized maintenance
intervals. With higher dirt capacity,
the new Cat hydraulic return filter
boasts a 3,000-hour service life - a
50 percent increase over previous
filters. An air filter with integrated
pre-cleaner, and primary and
secondary filters, extends service
life to 1,000 hours - a 100 percent
increase - while a new fuel tank
cap filter extends service life to
2,000 hours. Each model's fuel
system filter has a 500-hour service
interval.
Equipped with standard features
like keyless push-button start, large
standard 8-inch touchscreen monitor with jog dial keys for control,
and sound-suppressed rollover
protective structures (ROPS), all
Next Generation Excavator cabs

offer the next level of operator
comfort, safety and quiet operation.
In addition, the new 320 and
323 are equipped with integrated
Cat Connect Technology, which
increases operating efficiency by
up to 45 percent over traditional
grading operations.

Utility vehicles built to work
Caterpillar's first-ever utility
vehicles, the CUV82 and CUV102D,
offer durability, comfort and maintenance simplicity at a competitive
price.
A rugged steel cargo bed, with
1,000-pound total rear cargo
capacity and 2,000-pound towing
capacity, is designed for outstanding
performance in a variety of applications. A four-wheel independent
suspension system, with a front
sway bar, provides unmatched stability at full load. A long swing-arm
suspension, custom-tuned springs
and shocks balance a smooth ride
with hauling loads. Ample ground
clearance ensures these vehicles
navigate rough terrain with ease.
These new Cat UTVs efficiently
complete hauling tasks, quickly

maneuvering over rugged terrain
at speeds reaching 45 mph, depending on model. The CUV82 is
powered by a 0.8L, three-cylinder,
50-horsepower gasoline engine;
the CUV201D has a 1.0L, three-cylinder, 25-horsepower diesel
engine.
Features such as smooth
acceleration, clear sightlines and
engine braking capability make the
Cat UTV well-suited for hauling and
towing. The intuitive column shifter
allows the driver to easily maneuver
through all the gears. Both models
feature a continuously variable
transmission, tuned specifically for
work applications, offering smooth
transitions and the ability to handle
loads.
The choice of two-wheel drive,
four-wheel drive or four-wheel
drive/lock modes permits the driver
to match vehicle drive to ground
conditions.
Easy access to service points
simplifies vehicle maintenance,
while on-board advanced diagnostics reduce troubleshooting time.
