Product Description
The used Cat 320CL is a stalwart in the 20-ton+ excavator class, renowned for its rugged performance in heavy construction, earthmoving, and even light mining operations. Built with Caterpillar’s legacy of durability, this machine combines power, precision, and longevity, making it a top choice for contractors seeking a reliable workhorse that can handle demanding job sites with ease.
Advantages
A key advantage of the Cat 320CL is its exceptional power-to-weight balance. With an operating weight typically ranging from 20,000 to 21,500 kg, it delivers the stability needed for deep excavation and heavy lifting, while maintaining enough maneuverability to navigate busy construction sites. Its Cat C6.4 ACERT engine, pumping out approximately 110 kW (148 HP) at 2,000 rpm, ensures consistent performance—whether digging through compacted soil, loading trucks with aggregate, or breaking up concrete.
Durability is baked into its design. The 320CL features a reinforced boom and arm, heavy-duty undercarriage, and high-strength steel components that resist wear and tear, even in harsh conditions. The hydraulic system, operating at 34.3 MPa, is engineered for efficiency and responsiveness, with minimal energy loss—reducing fuel consumption and lowering operational costs over time. This reliability translates to less downtime, a critical factor for meeting project deadlines.
Another standout benefit is its versatility. Compatible with a wide range of attachments—from standard buckets (0.8–1.2 cubic meters) to breakers and grapples—it adapts to tasks like trenching, demolition, and material handling, eliminating the need for multiple machines and streamlining workflow.
Features
The Cat 320CL is packed with features that enhance productivity. Its maximum digging depth of around 6,500 mm and reach of 9,800 mm at ground level make it capable of tackling deep foundations and long-reach tasks, while the 6,200 mm maximum dump height ensures efficient loading into haul trucks. The 11 rpm swing speed allows for quick positioning, reducing cycle times between digging and dumping.
The undercarriage, with a 4,100 mm track length, 2,300 mm track gauge, and 600 mm track width, provides a stable base with a ground pressure of approximately 58 kPa—suitable for both soft and hard terrain. This stability is crucial for safe operation when working on slopes or uneven ground.
Operator comfort is prioritized with an enclosed cab featuring air conditioning, an adjustable suspension seat, and intuitive controls. The ROPS/FOPS-certified structure protects against rollovers and falling debris, while excellent visibility from the cab enhances precision and safety. The 380-liter fuel tank supports extended work sessions, minimizing refueling stops.
