Engine

Reduced emissions, economical and reliable performance

Cat® C6.6 ACERT™ Engine

The Cat C6.6 ACERT engine delivers more horsepower
usingless fuel than the previous series engine.

Emissions Solution

Equipped to meet U.S. Tier 4 emission standards, the
320ELRR’s C6.6 ACERT engine features an aftertreatment
regeneration solution that requires no operator intervention.
Theregeneration process automatically starts once the
ltering system reaches acertain level – with no interruption
to machine performance or the work process.

Biodiesel-Ready Fuel System

The C6.6 ACERT engine is equipped with an electronic­controlled high-pressure fuel system that includes an electric
priming pump and three-layer fuel hoses to allow the use
ofbiodiesel (meeting ASTM 6751 or EN14214) up to
B20(biodiesel 20% mixture).

Cooling System

The cooling system features an air-to-air aftercooler and
A/Ccondenser positioned for easy servicing; the viscous fan
automatically adjusts to ambient temperatures to help reduce
fuel consumption and noise.

Speed and Power Control

The 320ELRR features speed control to maintain a
constantspeed – regardless of load – to improve fuel
economy. Three different power modes are offered: high
power, standard power, and economy power. The operator
can easily change between modes through the monitor or
console switch to meet the needs for the job at hand – all
tohelp manage and conserve fuel.

3

Operator Station

Comfort and convenience to keep people productive

Seats

The seat range includes air suspension and heated options.
All seats include a reclining back, upper and lower seat slide
adjustments, and height and tilt angle adjustments to meet
operator needs for comfort and productivity.

Controls

The right and left joystick consoles (1) can be adjusted to
meet individual preferences, improving operator comfort and
productivity during the course of a day. With the touch of a
button, one-touch idle reduces engine speed to help save fuel;
touch it again or move the joystick and the machine returns
to normal operating level.

Monitor

The 320ELRR is equipped with a 7" LCD (Liquid Crystal
Display) monitor (2) that’s 40% bigger than the previous model’s
with higher resolution for better visibility. In addition to an
improved keypad and added functionality, it’s programmable
to provide information in a choice of 42 languages to
support today’s diverse workforce.

An “Engine Shutdown Setting” accessible through the monitor
allows owners and operators to specify how long the machine
should idle before shutting down the engine, which can save
signicant amounts of fuel.

The image of the rearview camera is displayed directly on the
monitor. Up to two different camera images can be displayed
on the screen.

Power Supply

Two 12-volt power supply sockets are located near key
storage areas for charging electronic devices.

Storage

1

Storage spaces are located in the front, rear, and side consoles.
A specic space near the auxiliary power supply holds MP3
players and cell phones. The drink holder accommodates
large mugs with handles, and a shelf behind the seat stores
large lunch or toolboxes.

Automatic Climate Control

The climate control system features ve air outlets with
positive ltered ventilation, which makes working in the heat
and cold much more pleasant.

Reduced Radius

Designed for high maneuverability in conned spaces

Reduced Radius

The 320ELRR’s tail swing radius is 2080 mm (6'10") compared to 2830 mm (9'3") on the 320E.
Whenrotated 90 degrees and working over the side, just 500 mm (1'6")* hangs over the side, allowing
the320ELRR to work well in road construction applications and other space-restricted areas.

Stability

The 320ELRR offers a stable platform for all applications. When compared to 320EL, the 320ELRR
delivers up to 16% additional lift over the side with the heavier counterweight. One of the main contributors
is the use of an additional counterweight, which allows the balance of the machine to be comparable to a
standard machine with a longer tail swing.

Comfort

While the length of the upper structure is reduced to accommodate the work at hand, the cab of the
320ELRR is the same size with all the amenities and attachments found inside the 320EL.

*With 790 mm (31") shoe.

Hydraulics

Power to move more dirt, rock, and debris with speed and precision

Hydraulic Horsepower

Hydraulic horsepower is the actual machine power available
to do work through implements and work tools. It’s much
more than just the engine power under the hood – it’s a core
strength that differentiates Cat machines from other brands.

Hydraulic Pumps

The 320ELRR uses a two-pump, high-pressure hydraulic
system to tackle the toughest work in short order. A highly
efcient and simple back-to-back main control valve improves
fuel consumption and allows for greater tool versatility.

Heavy Lift

The 320ELRR features a heavy lift function to give more lift
capacity over the front. With a touch of a button, pressure
increases and engine speed reduces to give better control in
lifting those extra-tough-to-move materials like concrete pipe
and road construction barriers.

Swing Priority Circuit

The swing priority circuit on the 320ELRR uses an electric
valve that’s operated by the machine’s Electronic Control
Module (ECM). Compared to using a hydraulic valve, an
electric valve allows for more nely tuned control, which
iscritical during material loading.

Electric Boom Regeneration Valve

This valve minimizes pump ow when the boom lowers
down, which helps improve fuel efciency. It is optimized
for any dial speed setting being used by the operator,
which results in enhanced boom lowering speed for greater
controllability.

Structures & Undercarriage

Built to work in rugged environments

Frame

The 320ELRR features a solid foundation that’s built
toabsorb the stresses of every day work. The main frame
utilizes high-tensile-strength steel and a one-piece swing table
to improve strength and reliability. The X-shaped carbody
is designed to resist bending and twisting forces. Theupper
frame includes reinforced mountings to support the Roll­Over Protective Structure (ROPS) cab; the lower frame
isreinforced to increase component durability.

Undercarriage

The undercarriage is built to support various work
applications. Precision-forged carrier rollers, press- t pin
master joints, and enhanced track shoe bolts improve
durability and reduce the risk of machine downtime and
the need and cost to replace components. Heavy-duty
rollers and idlers are sealed and lubricated to extend service
lift. Track links are assembled and sealed with grease to
decrease internal wear and increase life compared to dry seal
undercarriage. Also, a segmented two-piece guiding guard is
now offered to help maintain track alignment and improve
performance in multiple applications.

Counterweights

Two counterweight options are available: 6.2 mt (6.8 ton)
and 6.9 mt (7.6 ton). Integrated links enable easy removal of
the counterweight for maintenance or shipping.

8

Front Linkage

Made for high stress and long service life

Booms and Sticks

The 320ELRR is offered with a range of booms and sticks (see list below). Each is built with internal baf e
plates for added durability, and each undergoes ultrasound inspection to ensure weld quality and reliability.

Large box-section structures with thick, multi-plate fabrications, castings, and forgings are used in high-stress
areas such as the boom nose, boom foot, boom cylinder, and stick foot to improve durability.

The boom nose retention method is a durable captured ag design. Boom durability is improved with
anumber of plate thickness changes. Also, the front linkage pins’ inner bearing surfaces are welded,
andaself-lubricated bearing is used to extend service intervals and increase uptime.

Selections

There are two basic boom options: HD and ES.

• HD = Heavy Duty – This type of boom is designed to balance reach, digging force, and bucket capacity.

It covers the vast majority of applications such as digging, loading, trenching, and working with
hydraulic tools.

• ES = Extreme Service – This type of boom is best used for demolition or extreme applications where

stress loads on the boom are increased. It should be used for demanding, harsh applications like
100%rock and extensive hammer use.

Work Tools

Dig, hammer, rip, and cut with condence

An extensive range of Cat Work Tools for the 320ELRR
includes buckets, compactors, grapples, scrap and demolition
shears, multi-processors, pulverizers, hammers and thumbs.
Each is designed to optimize the versatility and performance
of your machine.

Quick Couplers

Quick couplers allow one person to change work tools in
seconds for maximum performance and exibility on a job
site. One machine can move rapidly from task to task, and
a eet of similarly equipped machines can share a common
work tool inventory.

Cat Center-Lock™ Pin Grabber Coupler

Center-Lock is the pin grabber style coupler featuring a
patented locking system. A highly visible lock clearly shows
the operator when the coupler is engaged or disengaged from
the bucket or work tool.

Buckets

Cat buckets are designed as an integral part of the
320ELRR system and feature new geometry for better
performance. The leading edge has been pushed forward,
resulting in more ef cient lling and better operator control
for greatly improved productivity. Wear coverage in the
corners and side cutter and sidebar protector coverage are
improved. All benets are captured in a new bucket line
witha new bucket naming convention.

Caterpillar offers standard bucket categories for excavators.
Each category is based on intended bucket durability when
used in recommended application and material. Buckets are
available as pin-on or can be used with a quick coupler.

10

General Duty (GD)

GD buckets are for digging in low-impact, low-abrasion
material such as dirt, loam, and mixed compositions of dirt
and  ne gravel.

Heavy Duty (HD)

The most popular bucket style, HD buckets are a good
starting point when digging conditions are not well known
like a wide range of impact and abrasion conditions
including mixed dirt, clay, and rock.

Severe Duty (SD)

SD buckets are for higher abrasion conditions such as
wellshot granite and caliche. Red area on bucket image
illustrates additional protection against wear as compared
toa GD bucket.

Specialty Buckets

In addition to the standard four bucket categories, specialty
bucket styles are available for the 320ELRR, each with a
different purpose:

• Ditch Cleaning buckets for cleaning ditches, slope

grading, and other  nish work.

• Center-Lock Pin Grabber Performance buckets for

maximum digging performance while keeping the
versatility and convenience of a coupler.

• Wide Tip buckets for low impact material where leaving

asmoother oor and minimal spillage are necessary.

Hydraulic Kits

Caterpillar offers eld-installed hydraulic kits that are uniquely
designed to integrate Cat Work Tool attachments with Cat
excavators. Hoses and tubes are pre-made, pre-shaped, and
pre-painted to make installation quick and easy.

Solutions that make work easier and more efcient

Cat® Grade Control Depth and Slope

This optional system combines traditional machine control and guidance
with standard factory-installed and calibrated components, making the
system ready to go to work the moment it leaves the factory. The system
utilizes internal front linkage sensors – well protected from the harsh working
environment – to give operators real-time bucket tip position information
through the cab monitor (1), which minimizes the need and cost for traditional
grade checking and improves job site safety. It also helps the operator
complete jobs in fewer cycles, which means less fuel use.

Cat Product Link

This optional system is deeply integrated into the machine monitoring system
and is designed to help customers improve their overall  eet management
effectiveness. Events and diagnostic codes as well as hours, fuelconsumption,
idle time, machine location, and other detailed information are transmitted
to a secure web based application (2 and 3) called VisionLink™, which uses
powerful tools to communicate to users and dealers.

access to the cooling and engine compartments. Both doors
and hood feature enhanced hardware and a new screen
design tohelp minimize debris entry.

Compartments

The compartments are designed to provide technicians with
quick access to major components and regular service items
like lters. The fresh air lter (3), for example, is located onthe
side of the cab to make it easy to reach and replace asneeded.

Other Service Enhancements

The water separator with water level sensor has a primary
fuel lter element located in the pump compartment near
ground level.

The fuel tank features a remote drain cock located in the
pump compartment to make it easy to remove water and
sediment during maintenance.

The engine oil check gauge is situated in front of the engine
compartment for easy access, and a uniquely designed drain
cock helps prevent spills.

Hydraulic lash adjusters automatically adjust valve opening
and closing events to help reduce fuel consumption and
engine noise. They also eliminate the need for a valve lash,
which reduces maintenance for the customer.

Caterpillar recommends using appropriate work tools to maximize the value customers receive from our products. Use of work tools, including buckets, which are
outside of Caterpillar’s recommendations or specifications for weight, dimensions, flows, pressures, etc. may result in less-than-optimal performance, including
but not limited to reductions in production, stability, reliability, and component durability. Improper use of a work tool resulting in sweeping, prying, twisting and/or
catching of heavy loads will reduce the life of the boom and stick.
