Engine and Hydraulics
Cat 3126B ATAAC engine and hydraulics give the 322C L exceptional power, efficiency and
controllability unmatched in the industry for consistently high performance in all applications.
Low sound, low vibration. The 3126B
ATAAC design improves operator
comfort by reducing sound and vibration.
Hydraulic Cross Sensing System.
Improves productivity with faster
implement speeds and quicker,
stronger pivot turns.
Fine Swing Control. The Fine Swing
Control cushions swing start and stop
for better implement control.
Hydraulic Cylinder Snubbers. The
hydraulic cylinder snubbers at rod-end
of boom cylinders and both ends of the
stick cylinder cushion shocks, reduce
sound and increase cylinder life, keeping
the machine working longer.
Controllability. The hydraulic system
offers precise control to the 322C L,
reducing operator fatigue, improving
operator effectiveness and efficiency,
which ultimately translates into
enhanced performance.
Boom and Stick Regeneration Circuit.
Boom and stick regeneration circuit
increases efficiency and reduces cycle
times for higher productivity and lower
operating costs.
Engine. Six cylinder turbocharged
engine built for power, reliability,
economy, and low emissions will
keep the machine up and running.
4
Automatic Engine Speed Control. The
two-stage, one-touch control maximizes
fuel efficiency and reduces sound levels.
Structures
322C L structural components and undercarriage are the backbone of the machine’s durability.
Robotic Welding. Up to 95% of the
structural welds on a Caterpillar
excavator are completed by robots.
Robotic welds achieve up to three
times the penetration of manual welds.
Carbody Design and Track Roller Frames.
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.
Main Frame. Rugged main frame
is designed for maximum durability
and efficient use of materials.
Undercarriage. Durable Cat
undercarriage absorbs stresses
and provides excellent stability.
Grease Lubricated Track. Grease
Lubricated Track link assemblies
will improve internal wear life by 25%
or more over sealed track. Decrease
undercarriage noise and the potential
for frozen or seized track joints.
Rollers and Idlers. Sealed and lubricated
track rollers, carrier rollers and idlers
provide excellent service life, to keep
the machine in the field longer.
Long Undercarriage. The long (L)
undercarriage maximizes stability and
lift capacity. A long, wide, and sturdy
undercarriage offers a very stable
work platform.
5
Booms and Sticks
Built for performance and long service life, Caterpillar booms and sticks are large, welded,
box-section structures with thick, multi-plate fabrications in high-stress areas.
Reach Boom. The reach boom features an
optimum design that maximizes digging
envelopes with three stick choices.
R2.5S Stick. The R2.5S stick provides
a good digging envelope with larger
buckets and stability for hammer work.
R2.95S Stick. The R2.95S stick is the
most versatile front linkage on the
322C L. It is a good fit with all 11-ton
dump trucks.
R3.6B Stick. The R3.6B stick gives the
largest working envelope.
6
Mass Excavation Boom. The mass
excavation boom maximizes productivity.
The mass version offers significantly
higher digging forces and allows use
of larger buckets.
M2.5D Stick. The M2.5D stick gives a
limited envelope but allows the use of
large buckets with high digging forces.
Operator Station
Redesigned interior layout maximizes operator space and provides exceptional comfort.
Operator Station. The 322C L operator
work station is quiet with ergonomic
control placement and convenient
adjustments, low lever and pedal
effort, ergonomic seat design and
highly efficient ventilation.
Redesigned Layout. Redesigned cab
layout emphasizes simplicity and ease
of use. Right-hand wall and console
provide easy access to all switches,
dials and controls.
Travel Controls. A large rubber-covered
footrest at the side of the travel pedals
allows the foot to easily grip the pedal.
The travel lever stroke and force have
been enhanced to improve the 322C L’s
fine controllability, making the machine
easier to operate.
Seat. A new seat with a two-tone color
offers two types of cushions, soft and
firm, for operator comfort. The reclining
knob is located at the right-side of the
seat for easier reclining adjustment.
Console. Redesigned consoles
feature simplicity and functionality.
Both consoles have attached
adjustable armrests.
Automatic Climate Control. Fully
automatic climate control adjusts
temperature and flow and determines
which air outlet is best in each situation.
Upper Cab Door Window. The upper cab
door window slides open, providing extra
ventilation and allowing communication
with people outside.
Skylight. A large polycarbonate skylight
delivers excellent natural lighting and
good ventilation. Standard sliding
sunshade protects the operator from
direct sunlight.
Monitor. New, compact monitor
enhances viewing while displaying a
variety of easy to read and understand
language-based information.
Automatic Boom and Swing Priority
Function. For simpler operation, Work
Mode and Power Mode switches have
been eliminated. Instead, the Automatic
Boom and Swing Priority Function
selects the best mode, based on
joystick movement.

Work Tools - Attachments
Increased offerings of work tools help optimize machine performance.
Heavy-Duty (HD) Buckets. Heavy-duty
buckets are for digging in moderate to
hard material and feature large ground
engaging tools, thick cutting edges and
thick bottom and side wear plates to
improve performance in demanding
conditions.
Quick Couplers. The Pin Grabber Plus
and the Dedicated Hydraulic Quick
Coupler enhance machine versatility
by enabling the rapid change over of a
wide range of work tools in the field.
General Purpose (GP) Buckets. General
Purpose Buckets are best for digging
in soft to hard ground with low to
moderately abrasive materials.
8
Ditch Cleaning (DC) Buckets. These
wide shallow buckets are best for bank
forming, ditch cleaning, and finishing.
Heavy-Duty Rock (HDR) Buckets.
Heavy-Duty Rock Buckets perform
best when digging fragmented rock,
frozen ground, caliche, and highly
abrasive materials.
Heavy-Duty Power (HDP) Buckets.
Designed to improve breakout force
and machine cycle times, the Heavy
Duty Power Bucket (HDP) compliments
the General Purpose, Heavy Duty, and
Heavy Duty Rock bucket lines.
Monitor. With the optional Tool Control
System, up to five different tool settings
may be pre-programmed and selected
from the electronic controller through
the monitor.

Serviceability
Simplified service and maintenance features save you time and money.
Ground Level Service. The design and
layout of the 322C L were made with
the service technician in mind. Many
service locations are easily accessible
at ground level, allowing critical
maintenance to get done quickly
and efficiently.
Pump Compartment. A service door
on the right side of the upper structure
allows ground-level access to the pump
and pilot filter.
Capsule Filter. The hydraulic return
filter, a capsule filter, is situated outside
the hydraulic tank. This filter prevents
contaminants from entering the system
when hydraulic oil is changed and
keeps the operation clean.
Diagnostics and Monitoring. The 322C
SM
L is equipped with S•O•S sampling
ports and hydraulic test ports for the
hydraulic system, engine oil and for
coolant. A test connection for the
Electronic Technician (Cat ET) is
located behind the cab.
Anti-Skid “Punched Star” Plate. Antiskid punched-star plate covers top of
storage box and upper structure to
prevent slipping during maintenance.
The plate can be removed for cleaning.
Extended Service Interval. 322C L
service and maintenance intervals have
been extended to reduce machine service
time and increase machine availability.
Radiator Compartment. The left rear
service door allows easy access to the
engine radiator. A reserve tank and
drain cock are attached to the radiator
for simplified service.
10
Air Filter Compartment. The air filter
features a double-element construction
for superior cleaning efficiency. When
the air cleaner plugs, a warning is
displayed on the monitor screen inside
the cab.
Fan Guard. Engine radiator fan is
completely enclosed by fine wire
mesh, reducing the risk of an accident.
Greasing Points. A concentrated remote
greasing block on the boom delivers
grease to hard-to-reach locations.
