The Ultimate Guide to Buying a Used Cat 320 Excavator

1. Understanding the Basics of the Used Cat 320 Excavator

When evaluating earthmoving equipment, the used Cat 320 excavator consistently stands out in the global 20-ton class. This machine seamlessly integrates advanced factory-installed technology to improve operator efficiency on every shift.

What is the Cat 320 excavator?

The Cat 320 is a highly versatile hydraulic machine designed for medium to heavy-duty earthmoving applications. It features a robust Cat C7.1 engine that delivers 117 kW (157 hp) of net power. The advanced hydraulic system balances this raw power with intelligent, class-leading fuel efficiency. This precise engineering makes a used Cat 320 excavator an ideal choice for contractors looking to scale economically.

Why is it Essential for Heavy Construction?

Standard integrated technologies like Cat GRADE 2D, Grade Assist, and Payload systems boost operator efficiency by up to 45%. This massive productivity spike directly translates to faster project completion times and significantly reduced labor costs. Furthermore, standard viscous mounts reduce cab vibration by up to 50%, ensuring operators remain comfortable and focused. A well-maintained used Cat 320 excavator provides massive return on investment for aggressively expanding fleets.

2. Common Specifications and Performance Data

Knowing the exact physical and mechanical parameters is crucial when purchasing any used Cat 320 excavator. Accurate specifications ensure the heavy machinery aligns perfectly with your expected operational workloads.

Engine Power and Fuel Efficiency

This model utilizes the reliable Cat C7.1 engine, which is fully capable of running on up to B20 biodiesel. It operates with a remarkable 20% reduction in overall fuel consumption compared to the previous 320D2 model. The Smart Mode automatically matches engine speed and hydraulic power to real-time digging conditions. This intelligent power management ensures your used Cat 320 excavator keeps fuel expenses strictly under control.

Digging Depth and Bucket Capacity

To ensure an optimized visual scanning pattern, here are the critical technical dimensions you must review. A standard used Cat 320 excavator delivers exceptional reach and load capacities.

• Operating Weight: 22,400 kg (49,400 lb), providing excellent foundational stability.
• Max Digging Depth: 6,720 mm (22’1″), ideal for deep utility trenching projects.
• Max Ground Reach: 9,860 mm (32’4″), allowing for wide-area excavation without moving.
• Bucket Capacity: 1.19 cubic meters (1.56 cubic yards) for heavy-duty earthmoving tasks.

3. Applications: Where to Use a Used Cat 320 Excavator

This hydraulic powerhouse excels across a diverse array of demanding global job sites. Its extreme versatility is a major reason why the used Cat 320 excavator remains highly sought after.

Earthmoving and Deep Trenching

This heavy equipment is perfectly suited for mass excavation, grading, and complex utility trenching. The standard Grade Assist automates both boom and bucket movements for precise, flat cuts. This guarantees accurate grading without requiring continuous, tiring manual adjustments by the operator. Consequently, a used Cat 320 excavator helps operators achieve perfect trenches much faster with less fuel.

Commercial Heavy-Duty Projects

For large commercial developments, lifting capacity and operational stability are paramount. The standard lift assist feature helps prevent tipping by calculating the safe load limit dynamically. Furthermore, the standard 2D E-fence prevents the machine from moving outside operator-defined boundaries. These factory safety features make the used Cat 320 excavator highly reliable for crowded commercial sites.

4. Frequently Asked Questions (FAQ)

International B2B buyers often have specific technical questions before finalizing a machinery investment. Here are common queries regarding the used Cat 320 excavator.

Cat 320 vs. 320D2: Which is Better for Your Project?

The next-generation Cat 320 offers massive technological improvements over the older 320D2 series. It delivers up to 20% lower fuel consumption and up to 20% lower overall maintenance costs. If upfront budget is extremely tight, a classic 320D2 remains a viable choice. However, for long-term operational savings, a next-gen used Cat 320 excavator is vastly superior.

How Much Does a Used Cat 320 Excavator Cost?

Market prices vary heavily based on the manufacturing year, working hours, and overall physical condition. Investing in a properly inspected used Cat 320 excavator often saves you 30% to 50% compared to buying new.

5. Inspection and Maintenance Best Practices

Proactive maintenance ensures maximum machine uptime and preserves its future resale value. Knowing what to meticulously check helps you secure a pristine used Cat 320 excavator.

Essential Checks Before Buying

Always request a fluid analysis (S.O.S) to check the inner health of the engine oil and hydraulics. Inspect the heavy-duty undercarriage components, including 600mm track shoes and rollers, for uneven wear. Ensure the high-resolution 8-inch touchscreen monitor and standard rearview camera operate smoothly. Verifying these exact elements guarantees your used Cat 320 excavator is ready for immediate deployment.

Tips to Prevent Wear and Prolong Lifespan

Adhere strictly to the extended, ground-level maintenance intervals designed specifically for this model. The new air filter with an integrated precleaner lasts up to 1,000 hours, twice as long as previous designs. Similarly, the advanced hydraulic oil filter boasts an impressive 3,000-hour replacement interval. Following these rigorous guidelines will keep your used Cat 320 excavator running flawlessly for years.
