Used CAT 320D2L Excavator for Construction and Earthmoving

The Used CAT 320D2L Excavator is a practical 21-ton-class crawler excavator for contractors, equipment distributors, rental companies and earthmoving fleets. Built around a strong crawler undercarriage, a high-capacity hydraulic system and the reliable Cat C7.1 diesel engine, this machine is suited to continuous excavation, trenching, loading and site preparation.

The unit shown is equipped with a long undercarriage, enclosed operator cab and approximately 1.0 m³ bucket. Its combination of a 5,700 mm boom, 2,900 mm stick and strong digging forces provides useful reach while maintaining stability during demanding work.

Powerful Cat C7.1 Diesel Engine

At the center of the CAT 320D2L is the Cat C7.1 six-cylinder diesel engine.

The engine has a displacement of approximately 7.01 L and a rated output of about 112 kW at 1,800 rpm. As a result, it provides the power needed for heavy digging while supporting smooth hydraulic operation.

In addition, the water-cooled engine system helps control working temperature during long operating shifts. This makes the excavator suitable for construction sites, quarry support, road projects and other applications where machines often work for many hours each day.

Main Specifications

Specifications may vary according to bucket, track shoe, boom, stick and individual machine configuration.

Strong Digging Performance

The CAT 320D2L provides approximately 125 kN bucket digging force and 104 kN stick digging force in the listed configuration.

This allows the machine to handle compact soil, clay, gravel and many common construction materials. Moreover, the hydraulic system delivers smooth boom, arm, bucket and swing movement. Operators can therefore perform repeated loading cycles without unnecessary delays.

The approximately 10.9 rpm swing speed also supports efficient truck loading and material repositioning.

Long Reach for Deep Excavation

With a 5.7 m boom and 2.9 m stick, this used CAT excavator provides a useful working envelope for medium and large construction projects.

Maximum digging depth reaches approximately 6,720 mm, while maximum digging radius is around 9,850 mm. Therefore, the machine can work efficiently on foundation excavation, drainage trenches, road construction and utility projects.

Its maximum dumping height of about 6,490 mm also makes it suitable for loading dump trucks and moving excavated material away from the working area.

Stable Crawler Undercarriage

The long crawler undercarriage gives the excavator a stable base during digging and lifting.

Wide track contact helps distribute machine weight and improves traction on gravel, soil and uneven construction surfaces. At the same time, the crawler design makes it easier to reposition the machine around an unfinished work site.

A maximum travel speed of approximately 5.4 km/h allows practical movement between nearby work areas.

Comfortable Operator Environment

The enclosed cab provides large glass areas for a clear view of the bucket, boom and surrounding work zone.

Hydraulic controls are positioned close to the operator, which helps reduce unnecessary movement during repeated digging cycles. The enclosed structure also provides better protection from dust, wind and changing weather conditions than an open operator station.

For used-machine buyers, the cab, controls, monitor, air conditioning, electrical system and safety devices can be checked as part of the pre-shipment inspection.

Suitable Applications

The Used CAT 320D2L can serve many types of construction and industrial projects:

• Foundation and basement excavation
• Road and highway construction
• Utility and pipeline trenching
• Land development and site preparation
• Quarry and aggregate handling
• Sand, soil and gravel loading
• Municipal engineering
• Drainage projects
• Demolition support
• General earthmoving

Its 21-ton working class provides a useful balance between digging capacity, transport requirements and operating flexibility.

Used Equipment Inspection and Supply

Before shipment, a used excavator should be checked according to its actual condition. Important inspection points include the engine, hydraulic pump, cylinders, hoses, control valve, swing system, travel motors, final drives, rollers, track chains, sprockets, bucket linkage and electrical components.

Machine year, working hours, serial number, bucket size and attachment configuration should also be confirmed individually.

For international equipment buyers, machines can be prepared according to project requirements, while photos, videos and detailed condition information can be supplied before order confirmation.
