320D2 GC HYDRAULIC EXCAVATOR

Enhance your comfort, operation, and visibility.

BENEFITS AND FEATURES

Operator Station The ergonomically designed operator station is spacious, quiet, and comfortable, assuring high productivity during a long work day. All switches are located on the right-hand console for convenient access. HAVC console is under the left hand armrest.

Monitor The new monitor consists of the master caution lamp, buzzer, monitor display screen, and keypad. Easy to see the display information ergonomically. It has the capability of displaying information in 42 languages.

Joystick Control Low-effort pilot-operated joystick controls are designed to match your natural wrist and arm position for maximum comfort and minimum fatigue.

Seat The suspension seat provides a variety of adjustments to accommodate a wide range of operators. All seats include a reclining back, upper and lower seat slide adjustments, and height and tilt adjustments, to meet operator needs for comfort and productivity.

The head rest can be adjusted to meet individual height preferences, improving operator comfort and productivity during the course of a day.

Climate Control 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.

Windows 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.

Wipers Pillar-mounted wipers increase your operator’s viewing area and offer continuous and intermittent modes.

A powerful engine with excellent reliability and low fuel consumption delivering more while boosting your bottom line.

BENEFITS AND FEATURES

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.

Filtration System 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.

Efficient hydraulic system with low effort joysticks provides precise control regardless of your application.

BENEFITS AND FEATURES

Hydraulic System 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.

Pilot System An independent pilot pump enables smooth precise control for the front linkage, swing, and travel operations.

Component Layout 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.

Strong and durable, all you expect from Cat excavators.

BENEFITS AND FEATURES

Main Frame The rugged main frame is extremely durable and designed for the toughest applications.

Standard Undercarriage 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.

Reliable and durable to meet all your application needs.

BENEFITS AND FEATURES

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.
