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.
Optional Fine Swing Control
Optional 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 stick cylinders cushion shocks, reduce sound and increase cylinder life, keeping the machine working longer.
Controllability
The hydraulic system offers precise control to the 320C, 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
Over 95% of the structural welds on a Caterpillar excavator are completed by robots. Robotic welds achieve over three times the penetration of manual welds.
Undercarriage
Durable Cat undercarriage absorbs stresses and provides excellent stability.
Booms and Sticks
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.
Work Tools - Attachments
Buckets
Caterpillar buckets provide increased service life with reduced repair costs.
Heavy-Duty Rock (HDR) Buckets
Heavy-Duty Rock (HDR) buckets perform best when digging fragmented rock, frozen ground, caliche and highly abrasive materials. Additional, thicker wear plates extend beyond side plates for corner and rear dent protection. Sidebar protectors decrease sidebar wear.
General Purpose (GP) Buckets
General Purpose (GP) buckets are best for digging in soft to hard ground with low to moderate abrasive materials.
Ditch Cleaning (DC) Buckets
These are wide shallow buckets for bank forming, ditch cleaning and finishing.
Heavy-Duty (HD) Buckets
Heavy-Duty (HD) buckets for digging in moderate to hard abrasive materials feature large Ground Engaging Tools (GET), thick cutting edges and thick bottom and side wear plates to improve performance in demanding conditions.
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. Up to five different tool settings may be pre-programmed and selected from the cab. Factory installed hammer and thumb circuits are also available as attachments.
Heavy Duty Power (HDP) Buckets
Designed to improve breakout force and machine cycle times, the Heavy Duty Power (HDP) Bucket compliments the General Purpose, Heavy Duty, and Heavy Duty Rock bucket lines.
Quick Couplers
The Pin Grabber Plus and the Dedicated Hydraulic Quick Couplers are available as field installed options. These attachments greatly enhance machine versatility by enabling the rapid changeover of a wide range of work tools in the field.
Work Tools
Choose from a variety of work tools such as hammers, shears, rotators, grapples or crushers. Ask your Cat dealer for information on attachments or special configurations.
Operator Station
Operator Station
The 320C 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 320C's fine controllability, making the machine easier to operate.
Seat
New, two-tone seat offers soft and firm cushions for operator comfort. Reclining knob is located at the right side of the seat for easy adjustment.
Console
Redesigned consoles for 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 from direct sunlight.
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.
Monitor
New, compact monitor enhances viewing while displaying a variety of easy to read and understand language-based information.
Attachment Controller
Five hydraulic pump flows and pressure settings can be preset on the monitor, eliminating the need to adjust the hydraulics every time a tool is changed and instantly providing the operator with the correct amount of flow and pressure for each tool. This feature is available with the optional tool control system.
Cab Exterior
Newly designed using asymmetrical steel tubing for improved resistance to fatigue and vibration. FOGS may be bolted-on directly to the cab.
Serviceability
Extended Service Interval
320C service and maintenance intervals have been extended to reduce machine service time and increase machine availability.
Radiator Compartment
The left rear service door allows access to the engine radiator and hydraulic oil cooler, which are side by side, and the high performance compact air-to-air aftercooler (ATAAC). Ample space between the ATAAC and the radiator/cooler is provided to allow access for cleaning.
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 320C was 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.
Swing-Out Condenser
The air conditioner condenser swings out horizontally for cleaning access.
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 320C 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 Cat Electronic Technician (Cat ET) is located behind the cab.
Handrails and Steps
Larger handrails and steps assist operator in climbing on and off machine.
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.
Grease Lubricated Track
Grease lubricated seals protect the track link and deliver long track link pin and bushing inner wear life.
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.
