Benefits & Features
Configurations
Log Loader
Purpose-built 36' live heel front, heavy counterweight and high-wide/high drawbar undercarriage combine to optimize log loading and shovel-logging operations.
Processor
Factory ready packages with heavy-duty roadside processing heads provide maximum efficiency in long log processing. Choose from standard gauge roadside configurations or high-wide/high drawbar for at-the-stump work.
Silviculture
When configured with the Special Application reach boom and stick and a variety of work tools, the 320C LL shows its versatility, from building right of way to reforestation.
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 LL, reducing operator fatigue, improving operator effectiveness and efficiency.
High Drawbar Final Drives
Standard on the high-wide undercarriage, high drawbar final drives offer increased mobility in demanding off-road applications. The two-speed control can be manually shifted or set in automatic.
Structures
Track Roller Frames
Robot-welded track roller frames are press-formed, pentagonal units to deliver exceptional strength and service life.
Heavy Duty Main Frame
Designed for maximum durability in forestry applications with reinforcements in the boom tower, boom cylinder pin and swing drive areas.
Undercarriage
Two forestry undercarriage options, standard gauge heavy-duty and high-wide/high drawbar, allow you to choose the right machine for your application. Both Cat undercarriages absorb stresses and provide excellent stability.
High-wide/High Drawbar Undercarriage
Increased ground clearance and drawbar pull allow better off-road capabilities, while increased track gauge improves stability in over-the-side applications.
Robotic Welding
Precision robotic welding ensures quality, increases rigidity, reduces internal stresses and enhances durability.
Rollers and Idlers
Sealed and lubricated track rollers, idlers and double-supported bottom rollers as carrier rollers provide excellent service life, to keep the machine in the field longer.
Operator Station
Interior Operator Station
The 320C LL operator work station is quiet with ergonomic control placement and convenient adjustments, low lever and pedal effort, ergonomic seat design and highly efficient ventilation.
Cab Exterior
Newly designed using asymmetrical steel tubing for improved resistance to fatigue and vibration.
Serviceability and Customer Support
Extended Service Interval
320C LL 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 and the oil cooler. A reserve tank and drain cock are attached to the radiator for simplified maintenance.
Integrated Catwalks
Designed to be integrated into the undercarriage house guards, the wide cat walks with "punched star" plate allow easy access to many service points.
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 LL 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 Oil Cooler
The oil cooler swings out horizontally for excellent 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 LL 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 (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.
Engine Inspection
Engine can be accessed from the upper structure or from under the machine. The engine and pump compartment are separated by a steel wall.
Handrails and Steps
Larger handrails and steps assist operator in climbing on and off machine.
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.
Selection
Make detailed comparisons of the machines you are considering before you buy. What are the job requirements? What production is needed? What is the true cost of lost production? Your Cat dealer can give you precise answers to these questions.
Purchase
Look past initial price, look at the value the 320C LL offers. Consider the financing options available as well as day-to-day operating costs.
Maintenance
Repair option programs guarantee the cost of repairs up front. Diagnostic programs such as Scheduled Oil Sampling and Technical Analysis help you avoid unscheduled repairs.
Replacement
Repair, rebuild or replace? Your Cat dealer can help you evaluate the cost involved so you can make the right choice.
Product Support
You will find nearly all parts at our dealer parts counter. Cat dealers utilize a worldwide computer network to find in-stock parts to minimize machine down time. Save money with remanufactured components.
Operation
Improving operating techniques can boost your profits. Your Cat dealer has training literature and other ideas to help you increase productivity.
