311D LRR Hydraulic Excavator. Unmatched
versatility, controllability, easy operation and a comfortable,
redesigned operator station help make the 311D LRR an
industry-leading performer.

Operator Station

Enhanced comfort, operation and visibility

Experience a spacious, quiet and comfortable operator station.
The cab is pressurized to reduce the amount of dust that enters
the cab, keeping the operator comfortable the entire shift, while
assuring high productivity during long work days.

• The comfortable seat adjusts to suit the operator’s size and
weight. Available as an option is a heated, air suspension seat.

• Standard air conditioning with automatic climate control
adjusts temperature and airfl ow.

• Low effort joystick controls are designed to match the
operator’s natural wrist and arm position. Joysticks can be
operated with arms on the adjustable armrests. The horizontal
and vertical strokes are designed to reduce fatigue.

Prestart Check and Monitor Display

Prior to starting the machine, the system checks for low engine
oil, hydraulic oil and engine coolant fl uid levels and warns the
operator through a color Liquid Crystal Display (LCD) monitor.
The LCD monitor displays vital operating and performance
information, in 28 languages, for operator convenience.

Cab Exterior

The 311D LRR provides a new cab design that allows a
Falling Object Guard System (FOGS) or front windshield
screen to be bolted directly to the cab, at the factory or in the
fi eld, enabling the machine to meet specifi cations and job site
requirements. The cab shell is attached to the frame with viscous
rubber cab mounts that dampen vibrations and sound levels to
enhance operator comfort.

Machine Security System

Engine

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 engine speed 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 311D LRR hydraulic system is designed
for high effi ciency and performance. Auxiliary hydraulic and
electrical lines are routed to the boom foot making installation
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 cylinders 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.

• Electronic Under Speed Control electronically adjusts pump
output to not exceed engine power, preventing the need to
reserve engine power to avoid engine stalls.

Boom and Stick Regeneration Circuit

The boom and stick 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 and 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
press-formed, pentagonal units that deliver exceptional strength
and service life. Idler and center guards help maintain track
alignment when traveling or working on slopes.

Grease Lubricated Track

Grease lubricated track protects the track link, delivers long track
pin and bushing inner wear and reduces sound levels.

Front Linkage

Reliable, durable and versatile

Built for performance and long service life, Cat booms and
sticks are welded, box-section structures with thick multi­plate 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.

Travel Motors

Travel motors with automatic speed selection let the 311D LRR
automatically change up and down from high and low speeds
in a smooth controlled manner.

Stick

Three stick options are available to meet your application
needs and increase performance and productivity. A new

2.6 m (8'6") intermediate stick is available to provide long
reach and increased digging and lifting capability.

Versatility

More options for more work

Work Tools

Caterpillar offers a variety of work tools, including hammers,
thumbs, grapples, multi, 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

An optional hydraulic pin grabber is available to pick up a
wide variety of 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
one-way or two-way hydraulic work tools, such as a mower,
priority for hydraulic fl ow.

• Medium Pressure Circuit is available as an attachment for work
tools requiring moderate hydraulic fl ow, such as a rotating
bucket or shears.

• A reduced tail swing radius allows the counterweight to
swing within the length of the tracks, reducing the potential
for damage to the machine and job site obstacles on busy
work sites, alongside roadways and around tight residential
construction jobs to name a few.

Serviceability

Simplifi ed service and maintenance saves time and money

Designed with the service technician in mind, many service
locations are at ground level so critical maintenance can be done
quickly and effi ciently. Longer maintenance intervals reduce cost
and increase machine availability.

• LCD monitor has the capability to memorize working hours
for fi lters, fl uids, components and work tools. Working time
histories and recommended change intervals can be displayed.

• Oil level gauge, fuel fi lter and priming pump are conveniently
located on engine structure for easy maintenance.

• An optional electronic fuel water sensor is available to alert the
operator when the water level is high.

• Product Link assists with fl eet management by tracking hours,
location and product health.

• New anti-skid plates over the top of the storage box and upper
structure help prevent slipping and mud from falling into the
upper structure.

Sampling Ports

Equipped with S•O•SSM sampling ports and test ports for
hydraulic, engine oil and coolant for quick diagnostics. A test
connection for the Cat Electronic Technician (Cat ET) service
tool is now located in the cab.

Air Cleaner

A double-layered fi lter core in the radial seal air fi lter gives more
effi cient fi ltration. A warning is displayed on the monitor when
dust accumulates above a preset level. This fi lter is conveniently
located in the compartment behind the cab. An optional
pre-cleaner is also available to extend fi lter life and reduce
maintenance costs.

Capsule Filter

Capsule-type, hydraulic return fi lter is accessible from outside
the tank and prevents contaminants from entering the system
when changing the hydraulic oil.
