Used CAT 320BL Crawler Excavator for Sale

The used CAT 320BL is a medium crawler excavator for earthmoving, roadwork, foundation digging, and site development. Its long undercarriage provides a broad and stable working base. Therefore, it is a practical option for contractors, equipment dealers, rental firms, and fleet owners.

Longmai Machinery supplies used construction equipment to business buyers worldwide. We provide current machine photos, operating videos, condition details, inspection support, and shipping plans. In addition, buyers can confirm the production year, working hours, serial number, attachments, and final condition before ordering.

Stable Long Undercarriage

The “L” in CAT 320B L refers to its long undercarriage configuration. This design gives the machine a longer track base and firm ground contact. As a result, the excavator can remain stable during digging, loading, and lifting work.

The steel crawler tracks are also suited to soil, gravel, and uneven sites. Meanwhile, the enclosed cab gives the operator a protected work area and a clear view of the boom, bucket, and surrounding jobsite.

Cat 3066T Engine

The CAT 320BL uses a Cat 3066T six-cylinder diesel engine. Reference data lists gross power at about 99.9 kW and net power at about 95.5 kW, both at 1,800 rpm. The engine displacement is approximately 6.37 L.

This engine provides steady power for daily digging and loading cycles. Moreover, its mechanical design is familiar to many service teams. Therefore, maintenance planning can be easier for companies that already operate Caterpillar equipment.

The reference fuel tank capacity is about 340 L, which helps support longer work periods between fuel stops.

Hydraulic Power and Work Efficiency

The main hydraulic system has a listed total pump flow of about 370 L/min. In addition, the reference maximum operating pressure is approximately 34.3 MPa.

This hydraulic output supports smooth boom, stick, bucket, travel, and swing movement. Consequently, the operator can handle trenching, loading, grading, and general excavation with controlled movement.

Bucket size depends on the machine setup. Reference configurations range from about 0.38 m³ to 1.53 m³, while a common bucket size is close to 0.92 m³. Different buckets and compatible hydraulic tools may be arranged according to the buyer’s work needs.
