Used CAT 320CL Crawler Excavator for Sale

The used CAT 320CL is a medium-size crawler excavator for daily construction work. It combines a long undercarriage, a proven diesel engine, and a practical working range. Therefore, it is suitable for contractors, equipment dealers, rental firms, and fleet owners.

Longmai Machinery supplies used construction equipment for projects and resale markets. Buyers can request current machine photos, a test video, condition details, and loading plans. In addition, we support attachment sourcing, export documents, and international shipment.

Built for Productive Earthmoving

The CAT 320CL belongs to the popular 20-ton excavator class. Its reference operating weight is about 20,800 to 21,400 kg, depending on the bucket, track shoes, and working equipment.

A standard setup often includes a 5,700 mm boom and a 2,900 mm stick. As a result, the machine offers a balanced mix of digging depth, reach, and lifting ability. Its bucket capacity usually ranges from 0.8 to 1.2 m³. Therefore, buyers can choose a setup for soil, clay, gravel, or general loading work.

The reference maximum digging depth is about 6,550 mm. Meanwhile, the ground-level reach is close to 9,800 mm. These figures make the machine useful for foundations, utility trenches, drainage work, and site development.

Long Undercarriage for Better Stability

The “L” in 320CL refers to the long undercarriage. This design gives the excavator a wider and more stable working base. Consequently, it can provide better balance during digging, lifting, and truck loading.

Steel crawler tracks also support work on loose soil and uneven ground. Moreover, the broad track contact helps spread the machine’s weight across the site. This makes the CAT 320CL a practical choice for roadwork, land clearing, and large excavation projects.

The pictured machine has an enclosed cab and steel tracks. However, track shoe width, bucket type, and other details should be confirmed for the selected unit.

Cat Engine and Hydraulic Power

The CAT 320CL commonly uses a Cat 3066 ATAAC six-cylinder diesel engine. Reference net power is about 103 kW, while gross power is about 110 kW. The engine has a displacement of about 6.4 L.

This engine provides steady power for excavation and loading. At the same time, the hydraulic system delivers controlled movement to the boom, stick, bucket, travel motors, and swing system.

The reference swing speed is 11.5 rpm. Travel speed is about 3.5 km/h in low range and 5.5 km/h in high range. Therefore, the machine can move between work areas without long delays.
