Benefits & Features
Engine and Hydraulics
Engine
Six cylinder turbocharged engine built for power, reliability, economy, and low emissions will keep the machine up and running.
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.
Structures
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.
Undercarriage
Durable Cat undercarriage absorbs stresses and provides excellent stability.
Booms and Sticks
Reach Boom
The reach boom features an optimum design that maximizes digging envelopes with three stick choices.
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.
R2.5S Stick
The R2.5S stick provides a good digging envelope with larger buckets and stability for hammer work.
R3.6B Stick
The R3.6B stick gives the largest working envelope.
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 M 2.5D stick gives a limited envelope but allows the use of large buckets with high digging forces.
Work Tools - Attachments
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.
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 (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.
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.
Work Tools
Choose from a variety of work tools such as hammers, shears, thumbs, rotators, grapples, or crushers. Ask your Cat dealer for information on attachments or special configurations.
Tool Control System
The optional Tool Control System maximizes work tool productivity by configuring hydraulic flow, pressure and operator controls to match a specific work tool. System versatility enables a wide range of tools to be used. Factory installed hammer and thumb circuits are also available as attachments.
Operator Station
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.
Serviceability
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.
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.
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 L is equipped with S•O•SSM 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
Anti-skid punched-star plate covers top of storage box and upper structure to prevent slipping during maintenance. The plate can be removed for cleaning.
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.
