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.
QA
- Q: What projects is the Cat 320CL best for?
A: It excels in heavy construction (building foundations, road
cuts), earthmoving (site grading, stockpiling), and light mining
(overburden removal).
- Q: How does it handle fuel efficiency?
A: The C6.4 ACERT engine’s advanced design optimizes fuel burn,
balancing power with economy—ideal for long workdays.
- Q: What’s the typical operating hour range for used models?
A: Well-maintained units often range from 5,000 to 15,000 hours,
with many lasting 20,000+ hours with proper servicing.
- Q: Can it work in tight spaces?
A: Its 2,600 mm tail swing radius is manageable for most
construction sites, though it’s best suited for medium to large job
areas.
- Q: What maintenance support is available?
A: Caterpillar’s global network offers parts, service, and
diagnostics, ensuring easy upkeep—critical for maximizing uptime.
