Product details
The 2021 Cat 320 is a reliable mid-size excavator that maintains strong performance in construction, roadwork, and material handling applications. Powered by a fuel-optimized Cat C4.4 engine, this used model delivers responsive digging power while meeting emission standards, with many units showing well-preserved mechanical condition. Its refined hydraulic system ensures smooth operation for precision tasks like trenching and grading, though hose and seal inspections are recommended due to age. The spacious ROPS-certified cab retains modern features including adjustable suspension seating, intuitive controls, and panoramic visibility - showing only minor wear in most pre-owned examples.Built with durable upper and lower frames, this second-generation 320 model withstands demanding job sites, though undercarriage components should be evaluated based on previous usage. The machine's quick coupler compatibility allows efficient attachment changes between buckets, hydraulic hammers, and sorting grapples. While not equipped with the latest connectivity, many 2021 units include basic telematics for maintenance tracking and operational data. Ideal for contractors seeking a cost-effective late-model excavator, this Cat 320 balances proven reliability with lower ownership costs for medium-duty projects.
Main features
High-Efficiency Powertrain: The 2021 Cat 320's proven C4.4 engine maintains excellent fuel efficiency while delivering consistent power for digging and loading tasks. Even as a pre-owned unit, well-maintained examples show minimal power loss, offering contractors an economical balance of performance and operating costs.
Smart Hydraulic Performance: This late-model hydraulic system retains its precision control for smooth operation in grading, trenching, and lifting applications. While seals and hoses may require inspection due to age, the pump and valve assemblies typically demonstrate reliable responsiveness with proper maintenance.
Operator-Centric Cabin: The ergonomic cab remains in good condition, featuring air-ride seating, intuitive controls, and excellent visibility through its large windows. The low-noise design and climate control system help reduce operator fatigue during extended shifts, making it ideal for demanding job sites.
Industrial-Grade Durability: Built with reinforced steel structures and a robust undercarriage, the Cat 320 withstands tough working conditions. Key stress points like the boom, arm, and swing bearing show only light wear in properly maintained units, ensuring continued reliability.
Versatile Attachment System: Compatible with a wide range of Cat and third-party attachments—including breakers, thumbs, and clean-up buckets—this excavator adapts easily to various tasks, from demolition to precision grading. The quick coupler functionality remains fully operational for efficient work tool changes.
Connected Worksite Intelligence: While not the latest generation, many 2021 models include Cat Product Link™ telematics for remote monitoring, maintenance alerts, and operational data tracking—helping optimize uptime and resale value for this cost-effective used excavator.
Application areas
Construction Engineering: The 2021 Cat 320 remains a workhorse for building projects, delivering reliable digging depth and breakout force for foundation work and site preparation. While pre-owned, well-maintained units maintain near-original productivity levels, offering contractors excellent value for commercial developments and residential construction sites.
Mining Operations: This durable excavator handles demanding quarry and mining tasks effectively, with its reinforced structure standing up to rigorous material loading and overburden removal. Buyers should verify undercarriage condition and hydraulic system health to ensure continued performance in harsh extraction environments.
Infrastructure Development: Ideal for roadworks and utility installations, the 320's precise hydraulic controls enable accurate trenching and grading. Its compact footprint (compared to larger excavators) allows efficient operation in constrained urban job sites while maintaining impressive lifting capacity.
Demolition and Dismantling: When equipped with appropriate attachments, this model provides stable platform for selective demolition work. The counterweight design and hydraulic flow rates support breakers and processors effectively, though boom reinforcement should be inspected on used units.
Landscaping and Site Development: The machine's smooth controls and grading capabilities make it valuable for finishing work in park development and estate projects. Many 2021 models retain their precision grading functions, offering landscape contractors an affordable late-model option.
