The head rest can be adjusted to meet individual height preferences, improving operator comfort and productivity during the course of a day.
Positive filtered ventilation with a pressurized cab is standard. Fresh air or re-circulated air can be selected with a switch on the left console.
Cab Structure and Mounts
The cab shell is attached to the frame with viscous rubber cab mounts, which dampen vibrations and sound levels while enhancing operator comfort. Thick steel tubing along the bottom perimeter of the cab, improves resistance to fatigue and vibration.
To maximize visibility, all glass is affixed directly to the cab, eliminating window frames. The upper front windshield opens, closes, and stores on the roof above the operator with a one-touch action release system.
Pillar-mounted wipers increase your operator’s viewing area and offer continuous and intermittent modes.
The Cat C4.4 ACERT engine with four cylinders has been designed to meet U.S. EPA Tier 3/EU Stage IIIA equivalent and China III Nonroad emission standards. The proven C4.4 ACERT engine incorporates robust components and precision manufacturing you can count on for reliable and efficient operation. Less sensitive to low quality fuel, it boasts improved reliability while delivering reduced fuel consumption.
L4 Droop with Underspeed Control
L4 droop with underspeed control contributes to efficiency by allowing the use of 100% of engine power. The Machine ECM (Electric Control Module) monitors engine speed and adjusts pump torque to deliver rated engine power. The need to reserve engine power to help prevent engine stall has been eliminated. This provides a substantial efficiency advantage.
Automatic Engine Control
Automatic engine control is activated during no-load conditions which reduces engine speed to minimize fuel consumption.
Electric Priming Pump
Eliminates the need for manual priming of fuel after filter changes. This pump reduces the risk of fuel contamination by preventing unfiltered fuel from being backfilled during filter changes as was possible with a manual hand priming pump.
Air Cleaner and Air Precleaner
The radial seal air filter features a double-layered filter core for more efficient filtration and is located in a compartment behind the cab.
A warning is displayed on the monitor when dust accumulates above a preset level. Air precleaner reduces the amount of dust and debris that enter the air intake system which can help maximize engine performance by extending air filter life.
An efficient filtration system provides robustness against contaminants in low fuel quality. The number of filters has been increased to three. The primary filter is a capable filter integrated water separator and the secondary twin filters with fine micron filtering capability improve filtration efficiency and machine robustness.
Low Sound, Low Vibration
The Cat C4.4 ACERT engine improves operator comfort by reducing sound and vibration.
Hydraulic system pressure is 35 000 kPa (5,076 psi) with 428 L/min (113.1 gal/min) flow from the two hydraulic pumps increases digging performance and productivity.
An independent pilot pump enables smooth precise control for the front linkage, swing, and travel operations.
The 320D2 GC hydraulic system and component locations have been designed to provide a high level of system efficiency. The main pumps, control valves, and hydraulic tank are located close together to allow for shorter tubes and lines between components, which reduce friction loss and pressure drops.
Boom and Stick Regeneration Circuits
Boom and stick regeneration circuits save energy during boom-down and stick-in operation which increases efficiency, reduces cycle times and pressure loss for higher productivity, lower operating costs, and increased fuel efficiency.
Hydraulic Cylinder Snubbers
Snubbers are located at the rod-end of the boom cylinders and both ends of the stick cylinders to cushion shocks while reducing sound levels and extending component life.
Return Capsule Filter
The return filter is a capsule filter which has a cartridge inside in order to avoid any contamination when accessing the filter and to enable changing cleanly without oil spillage. The capsule filter with little micro meter mesh size is capable of filtering out impurities. A sensor attached to the filter indicates if the filter is clogged and a warning goes off on the operator’s monitor in the cab.
The rugged main frame is extremely durable and designed for the toughest applications.
Durable Cat undercarriage absorbs stresses and provides excellent stability. The standard undercarriage is well suited for applications that require frequent repositioning of the machine, restricted work space, or uneven rocky terrain.
Carbody Design and Track Roller Frames
The X-shaped, box-section carbody provides excellent resistance to torsional bending. Robot-welded track roller frames are press-formed, pentagonal units to deliver exceptional strength and service life.
Rollers and Idlers
Sealed and lubricated track rollers, carrier rollers, and idlers provide excellent service life to keep your machine in the field and working longer.
Cat front linkages are designed for maximum versatility, productivity, and high efficiency.
Boom and Sticks
The 320D2 GC is offered with a 5.7 m (18'8") reach boom and two stick configurations to meet your application requirements:
- The 2.5 m (8'2") stick is designed for large, high-volume earthmoving work.
- The 2.9 m (9'6") stick is a very good fit for truck loading and trenching applications.
Cat buckets and Cat Ground Engaging Tools (GET) are designed and matched to the machine to ensure optimal performance and fuel efficiency.
Utility Buckets (UD)
These buckets are for digging in low-impact, low-abrasive material such as dirt, loam, and clay.
General Duty Buckets (GD)
