| |
| |
Engine and Hydraulics |
The Cato 3066TA engine and hydraulics give the 320D exceptional power, fuel efficiency, controllability unmatched in the industry for consistently high performance in all applications.
The layout further provides greater operator comfort by placing the radiator on the cab side of the upper structure. This allows incoming air to enter the engine compartment from the operator side and hot air and corresponding engine sound to exit on the opposite side away from the operator. This reduces engine compartment heat and sound being transmitted to the operator.
|
| |
| Pilot System.
|
| The pilot pump is independent from the main pumps and controls the front linkage, swing and travel operations. |
Hydraulic Cross Sensing System. |
The hydraulic cross sensing system utilizes each of two hydraulic pumps to 100 percent of engine power, under all operating conditions. This improves productivity with faster implement speeds and quicker, stronger pivot turns. |
| Auxiliary Hydraulic Valve |
The auxiliary valve is standard on the 320D. Control Circuits are available as attachments, allowing for operation of high and medium pressure tools such as shears, grapples, hammers, pulverizers, multi-processors and vibratory plate compactors. |

3066 TA Engine
|
| The Cat 3066 TA is a
six-cylinder turbocharged and aftercooled
engine with 103kw horsepower. The engine features long-stroke piston movement for high torque at medium to low speeds, which provides excellent fuel consumption of the 3066 TA engine with the new Economy Mode, customers can balance the demands of performance and fuel economy to suit their requirements and application |
|
|
| Automatic Engine Speed Control. |
Automatic Engine Control with convenient one-touch command. During no-load or light-load conditions, the Automatic Engine Speed reduces engine speed. This maximizes fuel efficiency and reduces sound levels. |
| |
| |
| |
|
|
Air Cleaner |
|
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. |
|
|
| Low sound, low vibration |
By design, the 3066 TA improves operator comfort by reducing sound and vibration. |
| |
|
|
| |
| |
| Component Layout. |
The 320D 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 in the lines. |
|
| Boom and Stick Regeneration Circuit |
Boom and stick regeneration circuit saves 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. |
|
|
|
| |
Structures
320D structural components and undercarriage are the backbone of the machine's durability |
|
Robotic Welding .
|
Up to 95% of the structural welds on a Caterpillaro Excavator are completed by robots. Robotic welds achieve over three times the penetration of manual welds. |
| |
Carbody Design and Track Roller Frames |
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. |
| |
| Main Frame. |
Rugged main frame is designed for maximum durability and efficient use of materials. |
| |
| Undercarriage |
Durable Cat undercarriage absorbs stresses and provides excellent stability. |
| |
| Hollers and Idlers |
Sealed and lubricated track rollers, carrier rollers, and idlers provide excellent service life, to keep the machine in the field longer. |
| |
| Standard Undercarriage |
| The standard undercarriage is well suited for applications that require frequent repositioning of the machine, have restricted working space or uneven, rocky terrain. |
| |
| Long Undercarriage. |
| The long (L) undercarriage maximizes stability and lift capacity. This long, wide, and sturdy undercarriage offers a very stable work platform. |

Service and Maintenance
Simplified service and maintenance features save you time and money |
| |
| Ground Level Service |
|
The design and layout of the 320D 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.
|
| |
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. |
| |
Pump Compartment.
|
A service door on the right side of the upper structure allows ground-level access to the pump and pilot filter. |
|
|
| |
| Radiator Compartment |
The left rear service door allows easy access to the engine radiator, oil cooler and air-to-air-after-cooler. A reserve tank and drain cock are attached to the radiator for simplified maintenance. |
|
| 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. |
|
|
|
| Greasing Points |
A concentrated remote greasing block on the boom delivers grease to hard-to-reach locations on the front. |
|
| Fan Guard. |
Engine radiator fan is completely enclosed by fine wire mesh, reducing the risk of an accident. |
|
|
|
| Anti-Skid Plate |
Anti-skid plate covers top of storage box and upper structure to prevent slipping during maintenance. |
|
| Diagnostics and Monitoring . |
The 320D is equipped with S-O-S'm 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) service tool is located behind the cab. |
|
|
|
| Anti-Skid Plate |
320D service and maintenance intervals have been extended to reduce machine service time and increase machine availability. |
