Used CAT 323GC Hydraulic Excavator
Product Information
The used CAT 323 GC is a 23-ton-class crawler excavator for general construction and earthmoving. It combines a Cat C7.1 engine, a modern hydraulic system, and a stable long undercarriage. Therefore, it is a practical choice for contractors, machinery dealers, rental companies, and fleet buyers.
The pictured machine has an enclosed cab, protective front grille, steel tracks, reach boom, and digging bucket. Longmai Machinery can provide current photos, a working video, condition details, and export support for the selected unit.
Balanced Performance for Daily Work
The CAT 323 GC is designed for light- to medium-duty excavation, loading, and trenching. Its reference operating weight is 22,700 kg. Meanwhile, a standard configuration includes a 5.7 m reach boom, 2.9 m stick, and 1.3 m³ general-duty bucket.
This setup gives the machine a useful balance of reach, digging force, and loading capacity. As a result, one excavator can handle several tasks across construction and infrastructure projects.
The long crawler undercarriage also provides a broad working base. Therefore, the excavator can remain stable during digging, lifting, and truck loading.
Cat C7.1 Engine and Smart Power Control
The CAT 323 GC uses a Cat C7.1 diesel engine with a 7.01 L displacement. Net power is 117 kW, while the listed engine power is 118 kW.
Two selectable power modes help match output to the job. In addition, Smart Mode can adjust engine and hydraulic power according to the digging load. This allows the operator to use the required power without running at maximum output throughout the whole shift.
Automatic engine speed control and idle shutdown can further reduce unnecessary running time. However, available settings may vary by regional configuration.
Hydraulic Output and Digging Range
The main hydraulic system provides a reference maximum flow of 429 L/min. Maximum equipment pressure is 35 MPa. Therefore, the machine can deliver controlled boom, stick, bucket, travel, and swing movement.
Reference bucket digging force is 140 kN, while stick digging force is 107 kN. These figures support work in soil, clay, gravel, and other common construction material.
With the standard reach configuration, the CAT 323 GC provides a maximum digging depth of 6,730 mm and a maximum ground reach of 9,870 mm. Moreover, its 6,490 mm loading height supports work with many common dump trucks.
Operator Cab and Jobsite Visibility
The enclosed cab provides a protected operating space. A high-resolution touchscreen monitor gives access to machine settings and operating information. In addition, a rearview camera can improve visibility behind the excavator.
The pictured unit also has a front protection grille. This feature is useful on sites where loose or flying material may be present. However, buyers should confirm the guard type and local safety requirements before use.
Other reference cab features include air conditioning, adjustable controls, a suspension seat, and joystick operation. Final equipment depends on the production year and regional version.
