CAT 323D3 Excavator

Powerful Cat C7.1 engine.

New and reinforced bucket resulting in increased performance and longer life.

Be productive with a large Cat 1.20 m³ (1.57 ydm³) severe-duty abrasive resistance bucket.

Dig and lift from a stable platform created by the heavy-duty counterweight and eight-roller undercarriage.

Electrohydraulic control valve, pump and ECM introduced for better controllability and lower fuel consumption.

The excavator has a high-ambient capability of 52° C (125° F) and cold start capability of –18° C (0° F). An optional –32° C (–25° F) cold start package is available.

Add versatility by adding tool control to run a hammer or other tools requiring one-way flow. Order tool control with the machine or add it later with a dealer-installed kit.

Balance power and efficiency using the open-center, positive flow control electro-hydraulic system.

Hydraulic cross-sensing makes full engine power always available from hydraulic pumps regardless of which function is used.

Reinforced HD Boom & Stick designed for quarry application.

Robust bottom guards protect machine components that might be damaged while swinging. A thicker bottom guard plate is used under the pump compartment to protect the suction hose.

Traverse the job site on the Grease Lubricated Track (GLT) undercarriage. Undercarriage rollers are rebuildable and sealed to prevent dirt and debris causing internal wear. Grease lubricated links minimize internal bushing wear, reducing noise and increasing life up to 25%.

Hydraulic snubbers in the boom and stick cylinders dampen end-of-stroke impact prolonging the life of your machine.

Expect reliable performance from the double-filtered low-pressure fuel system and antirust fuel tank protects the engine from lower quality fuel.

Optional full length/third track guard design provides greater machine ruggedness.

Stick and Boom structures designed using high-tensile steel fabricated into a large box section using internal baffles to absorb torsional stress. The single plate X-shaped, box-section car body provides excellent resistance to torsional bending, dissipating stress throughout the base of the machine.

Thick braiding protects the colored, numbered electrical wires. Non-abrasive connectors keep wiring harnesses in place to prevent failure. Show Less

Up to 10% less fuel consumption than the previous 323D3 model in similar applications. Economy mode further reduces fuel consumption with no loss in lifting or digging forces.

Save even more by using the Economy mode. Speed will reduce, but with no loss in lifting or digging forces. See savings of up to 20%.

Boom and Stick regeneration circuits contribute to reduce fuel consumption by up to 2%.

Use automatic engine speed control (AEC) during no-load or light-load conditions to automatically reduce engine speed to minimize fuel consumption.

Standard one-touch low idle saves fuel by instantly reducing engine speed to 1,000 rpm at the push of a button. Return the engine speed to the throttle position by hitting the button again or simply moving the joysticks.

Electronic Tandem hydraulic pump is 7% more efficient with less internal friction losses and superior design.

Optional Fuel Flow meter aids in reporting the fuel consumption through vision link.

15% lower maintenance costs than previous 323D3 models, with advanced hydraulic oil filter design and reduced number of filters.

Hydraulic system does not require a pilot filter, eliminating a filter that had to be changed frequently.

Updated hydraulic filter design. Preventing oil contaminants from entering the system during filter change no longer requires a capsule design.

Drain filter is replaced with a cleanable screen and magnet.

Extended first engine oil change interval (500 hours), and maintenance-free batteries.

A two-stage fuel filtering system with integrated water separator protects the engine from particles larger than four microns when fuel quality is less than ideal.

Easily maintain your machine. Most service locations are easily accessible at ground level for quick, efficient servicing to allow service and maintenance to get completed quickly and efficiently. A service door on the right side of the upper structure allows ground-level access to the hydraulic pumps, hydraulic filters, engine oil filter, and fuel filters.

There is no need to manually prime the fuel system after fuel filter changes. The standard electric priming pump reduces the risk of contamination by preventing unfiltered fuel from entering the fuel system.

Proven, high-efficiency radial seal engine air filter behind the cab. The machine constantly monitors the engine air filter and will notify you, via the monitor, when service is required.

A remote greasing block on the boom allows the greasing of hard-to-reach locations. A remote mounted greasing point on the swing bearing allows ease of service.

VisionLink™ comes standard so you can remotely monitor machine health, location, hours, and absolute fuel level on demand through the online interface.

The updated spacious cab design provides excellent visibility from the operator’s seat to keep you aware of your surroundings - without bending or straining to see.

In-cab high-resolution 203 mm (8 in) touch screen display are easy to use, intuitive and user-friendly.

Work a full day with less fatigue using the ergonomically designed electro-hydraulic joysticks matched to operator’s wrist and arm position. Joystick consoles can be adjusted, further improving operator comfort and productivity.

Easy to access radio controls, engine throttle, wiper controls and Bluetooth phone pairing for operator convenience.

Improved automatic climate control helps maintain consistent cab temperature. Five outlets ensure proper air circulation to keep you comfortable regardless of outside temperatures.

Ergonomically designed seat to improve operator’s comfort. Wide adjustable armrests and retractable seatbelt are also included.

Standard Cab Equipment. To enhance operator comfort and productivity, the cab includes a radio, lighter, drink holder, coat hook, service meter, literature holder, magazine rack and storage compartment.

Keep your phone or other personal electronics charged using the 24V auxiliary power ports delivering up to 5A of power.

There is plenty of room for you to store your gear. There are two storage locations at the rear of the right console and one space for your lunchbox behind the seat. Show Less

We designed the cab to provide excellent visibility from the operator’s seat. In addition, two standard mirrors help keep you aware of your surroundings.

The machine provides you a safe work platform for all routine service and maintenance needs. Anti-skid plating with countersunk bolts reduces the potential for slippage and trip hazards.

Grips on the track frame, service platform, cab and battery compartment for an easy, safe climb up and down from the service platform and operator station.

Handrails and hand hold are provided for easy access.

Optional rearview cameras with additional mirror enhance visibility behind the machine.

Optional ROPS compliant cab is now available.

Ground level access to engine secondary shut-off feature.

The hydraulic lockout lever prevents operators from leaving the cab without first isolating all hydraulic functions.

A lockable disconnect switch isolates the battery and enhances safety by disconnecting the electrical energy when servicing the machine.

A full-length firewall separates the engine from the hydraulic pump and offers protection in the event of an incident.

The machine can be equipped with a Operator Protective Guard (OPG) that conforms to the ISO 10262:1998 standard. These guards are bolted directly to the cab shell.
