Delivering the most work per liter/gallon of fuel consumed
The Cat® C4.2 engine with ACERT® Technology optimizes performance and meets U.S. EPA Tier 3 and EU
Stage IIIA regulations. In conjunction with integrated electronics, ACERT Technology reduces emissions
during the combustion process by using advanced technology in the air and fuel systems. The Cat C4.2 engine
delivers exceptional power, allowing more hydraulic pressure to drive productivity and reduce your cost per
ton of material moved.
Automatic Engine Control and Fuel Delivery
A two-stage control and one-touch low idle button maximize fuel effi ciency and reduce sound levels.
Fuel delivery is managed by the ADEM™ A4 Engine Controller for the best performance per liter (gallon)
of fuel used. Flexible fuel mapping allows the engine to respond quickly to varying application needs.
Crankshaft and Pistons
A forged, one-piece, induction hardened crankshaft enhances balance, decreases vibration and improves
abrasion resistance. Heat resistant, aluminum alloy pistons have a short compression height for greater
effi ciency and longer life.
Economy Mode
Accessible through the in-cab monitor, economy mode allows you to balance the demands of performance
and fuel economy while maintaining the breakout forces and lift capacity enjoyed at standard power.
4
Hydraulics
Low effort and precise control for highly effi cient performance
Outstanding Performance
With two percent more hydraulic pressure for additional lift and
breakout forces, the 314D hydraulic system is designed for high
effi ciency and performance. Auxiliary hydraulic and electrical
lines are routed to the boom foot as standard, making retrofi t
of hydraulic circuits much easier. This compact design utilizes
short tubes and lines, reducing friction and pressure drops,
resulting in a more effi cient use of power.
Hydraulic snubbers at the rod end of the boom cylinders and
•
both ends of the stick cylinder cushion shock, reduce sound
and increase cylinder life.
Flow is reduced to a minimum when controls are in neutral to
•
reduce fuel consumption and extend component life.
Hydraulic Cross-Sensing System uses two hydraulic pumps
•
up to 100 percent of available hydraulic horsepower under
all operating conditions, improving productivity with faster
implement speeds and quicker, stronger pivot turns.
Boom and Stick Regeneration Circuit
The boom and stick electronic regeneration circuit saves energy
during boom-down and stick-in operation, increasing effi ciency
and lowering operating costs.
Easy Operation
Work mode and power mode switches have been eliminated
making full power available at all times. Operators do not need
to learn different modes. An automatic boom and swing priority
function automatically selects the best mode based on joystick
movement.
5
Undercarriage/Structures
Strong, stable and easy to maneuver
Caterpillar uses advanced engineering and software to analyze
all structures, creating a durable, reliable machine for the
toughest applications. More than 70 percent of the structural
welds are robotic and achieve additional penetration over
manual welds. These structural components and undercarriage
are the backbone of the machine’s durability.
Carbody Design
X-shaped, box section carbody provides excellent resistance to
torsional bending. Robot-welded track roller frames are pressformed, pentagonal units that deliver exceptional strength and
service life. Idler and center guards (standard for LC option)
are available to help maintain track alignment when traveling
or working on slopes.
Grease Lubricated Track
Track links are assembled and sealed with grease to decrease
internal bushing wear and increase life by as much as 25 percent,
when compared to dry seal undercarriages.
Front Linkage
Reliable, durable and versatile
Built for performance and long service life, Cat booms and
sticks are welded, box-section structures with thick multi-plate
high strength steel fabrications. Service intervals are extended
with self-lubricating bearings that resist corrosion and galling
for superior durability.
Boom
The boom is designed for maximum digging capability and
is robotic welded to ensure consistent quality. This allows
excellent all-around versatility and a large working envelope.
Stick
Three stick options are available to meet your application
needs and increase performance and productivity. A new 2.8 m
(9'2") intermediate stick is available to provide long reach and
increased digging and lifting capability.
6
Travel Motors
Travel motors with automatic speed selection let the 314D
automatically change up and down from high and low speeds
in a smooth, controlled manner.
Versatility
More options for more work
Work Tools
Caterpillar offers a variety of work tools, including hammers,
thumbs, grapples, multi-processors, shears, pulverizers and
vibratory compactors to fi t your application needs. Additionally,
a wide range of buckets are available to optimize machine
performance.
Auxiliary hydraulic and electrical lines are routed to the boom
foot for easier installation of auxiliary hydraulic circuits, therefore
reducing time, parts and cost required to add a work tool.
Hydraulic Pin Grabber Coupler
An optional hydraulic pin grabber coupler is available to pick up
a wide variety of buckets and work tools without having to leave
the cab, thus maximizing productivity.
Enhanced Systems
Work tool functionality has increased the versatility of the
machine with the enhancement of the following:
An optional Combined System enables one or two pump fl ow
•
in one or two directions. With this system, only one hydraulic
circuit is required.
The Tool Control System stores up to 10 different tool settings
•
through the in-cab display monitor. Cat Work Tools are
selectable with preset fl ows and pressures.
Offered as an option, the Priority Flow System provides all the
•
advantages of the Combined System plus true priority fl ow for
hydraulic work tools such as rotary mowers.
Medium Pressure Circuit is available as an attachment for
•
work tools requiring additional auxiliary hydraulics such
as the rotate function on rotating grapples and shears.
Compact Radius
The shorter tail swing and tighter front swing radius allow the
operator to work safer and more effi ciently on space restricted
or congested job sites, focusing more on the work at hand
and less on counterweight clearance.

Compact Radius
Flexibility in tight quarters and peace of mind
Compact Radius Design
The 314D CR/314D LCR features a compact radius design
which makes it ideal for working in space restricted conditions
such as close to buildings, against walls/fences/embankments,
wooded residential lots, road construction – limiting lane
closures, logging roads or just generally “crowded” job sites.
This is not just a “city” machine. The tail swing radius is just
1.48 m (4'10") with the standard counterweight as compared
to 2.14 m (7'0") on the Cat 312D. When rotated 90 degrees
and working over the side, a minimal amount of counterweight
extends beyond the track width: 185 mm (7") of overhang with
600 mm (24") track shoes and standard counterweight. At the
end of the day, there is signifi cantly reduced risk of damage to
the machine and any job site obstacles which equates to lower
operating costs, better resale value, increased safety and more
operator comfort.
Operator Confi dence
Due to the 314D CR/314D LCR compact working envelope,
operators can work confi dently knowing that the counterweight
will not swing into objects behind them.
Comfort
The cab on the 314D CR/314D LCR is a comfortable place to
work, with low sound levels, good viewing area and convenient
access to the switches and controls. The 314D CR/314D LCR
cab offers many of the same amenities and options found on
the cab of the Cat 312D.
Working Envelope
To further minimize the working envelope, the boom is repositioned
more towards the center of the machine compared to a standard
excavator. This reduces the front swing radius when the boom
is pulled all the way up and the stick brought in completely.
