Second Hand Used CAT 323D L Hydraulic Excavator
Product Information
The used CAT 323D L is a 23-ton-class crawler excavator built for steady output on demanding job sites. It combines a 110 kW Cat C6.4 engine with a long undercarriage and a powerful hydraulic system. Therefore, it is well suited to contractors, equipment dealers, rental companies, and fleet buyers.
The pictured unit has an enclosed cab, steel crawler tracks, a digging bucket, and protective guards around the cab. Longmai Machinery can provide current machine photos, a working video, inspection support, and export service before shipment.
Productive Power for Daily Excavation
The CAT 323D L uses a Cat C6.4 ACERT diesel engine with a 6.4 L displacement. Its rated net power is 110 kW. As a result, the machine can deliver stable power for digging, lifting, loading, and attachment work.
Automatic engine speed control lowers engine speed during light-load or no-load periods. This helps reduce unnecessary fuel use and sound. Meanwhile, the 410 L fuel tank supports longer working periods between refueling stops.
The reference operating weight ranges from 22,300 to 23,100 kg. The exact figure depends on the boom, stick, bucket, track shoes, and other equipment.
Responsive Hydraulic System
Two main hydraulic pumps provide a maximum flow of 205 L/min each. In addition, the reference equipment pressure is 35 MPa. This output supports smooth control of the boom, stick, bucket, travel, and swing functions.
With the 5.7 m reach boom and 2.9 m stick, the machine provides about 140 kN of bucket digging force and 106 kN of stick force. Therefore, it can handle soil, clay, gravel, and other common construction material.
Optional hydraulic circuits may also support breakers, grapples, shears, pulverizers, and compactors. However, the actual auxiliary lines and flow settings must be checked on the selected machine.
Long Undercarriage and Stable Operation
The “L” designation refers to the long undercarriage. Its longer and wider crawler base improves machine stability during excavation and lifting. Moreover, the steel tracks provide firm ground contact on rough or uneven sites.
The maximum travel speed is about 5.7 km/h, while the maximum drawbar pull is 206 kN. The excavator also has a reference swing speed of 11.5 rpm. Together, these features support quick travel and controlled working cycles.
Track shoe options affect the overall width. For example, the transport width is approximately 2,980 mm with 600 mm shoes and can reach about 3,180 mm with wider shoes.

These figures describe a common CAT 323D L reach-boom configuration. Production year, regional version, bucket, stick, track shoes, and optional equipment can change the final data. Therefore, buyers should confirm the serial number and actual machine specifications before purchase.
Suitable Work Sites
The used CAT 323D L can support a wide range of commercial projects, such as:
- Road and bridge construction
- Foundation and basement excavation
- Pipeline and drainage trenching
- Land clearing and site preparation
- Soil, sand, and gravel loading
- Quarry support work
- Industrial construction
- Agricultural land development
- Rental fleet expansion
Different buckets and hydraulic tools can further expand its use. For this reason, buyers should provide their material type and project needs when requesting a quotation.
Condition Checks Before Shipment
Longmai Machinery can provide a unit-based inspection before the order is confirmed. The check may cover the engine, hydraulic pumps, cylinders, boom, stick, bucket, swing drive, travel motors, cab, and undercarriage.
Buyers can also request:
- Detailed exterior and component photos
- Cold-start and working videos
- Hydraulic response checks
- Undercarriage condition photos
- Serial plate and working-hour confirmation
- Buyer-appointed or third-party inspection
- Cleaning and basic maintenance
- Bucket and attachment matching
Since this is used equipment, normal wear may be present. Therefore, the final quotation should list the production year, working hours, machine condition, attachments, preparation work, and delivery terms.
