Cat 320c excavator

When sourcing a Cat 320c, the engine and hydraulic pump are the most critical components. You must verify that the Cat 3066 T diesel engine shows no signs of excessive blow-by or unusual smoke. Check the hydraulic system pressure to ensure it meets the original factory specification of 34,300 kPa (4,980 psi). Inspect the main control valve for leaks and ensure the swing motor operates smoothly without grinding noises. For used units, prioritize machines with under 10,000 operating hours to ensure a longer remaining service life.

The Cat 320c is a 20-ton class excavator known for its balance of power and fuel efficiency. Key specs include a net power of 103 kW (138 hp) and an operating weight of approximately 21,000 kg. Ensure the bucket digging force is around 130-140 kN. If your project requires deep excavation, verify the maximum digging depth (approx. 6.6 meters) and reach at ground level (approx. 9.8 meters). Always request the Product Identification Number (PIN) to verify the exact year of manufacture and configuration.

Ensure the machine complies with EPA Tier 2 or EU Stage II emission standards, depending on your local environmental regulations. For safety, the cabin must meet ROPS (Roll-Over Protective Structure) and FOPS (Falling Object Protective Structure) standards. If purchasing from a cross-border supplier on Made-in-China.com, request a third-party inspection report (such as CCIC or SGS) to validate the machine's safety features and structural integrity, especially the boom and arm welding points.

The undercarriage represents about 20% of the machine's value. Inspect the track links, rollers, and idlers for percentage of wear; anything over 75% wear will require immediate replacement. Check the sprocket teeth for sharpness, which indicates heavy use. For attachments, ensure the bucket teeth and side cutters are intact and that the quick coupler (if included) is compatible with your existing hydraulic attachments to avoid additional modification costs.

The biggest risks include misrepresented machine hours, hidden structural cracks, and refurbished parts passed off as original. To mitigate this, always use Secure Payment services provided by platforms like Made-in-China.com to ensure funds are only released after shipping documents are verified. Never rely solely on photos; request live video inspections of the machine under load (digging or lifting) to observe hydraulic response times.

Focus your negotiation on the Total Landed Cost. Ask the supplier to include wear-part kits (filters, seals, O-rings) for the first 1,000 hours of operation. If buying multiple units, aim for a 5-10% discount on the machine price or negotiate for Free on Board (FOB) terms where the supplier covers inland hauling and port loading fees. Always clarify who is responsible for export de-registration documents in the country of origin.

For a Cat 320c, Roll-on/Roll-off (RoRo) shipping is the safest and most common method, as the machine is driven directly onto the vessel. Alternatively, Flat Rack containers can be used if RoRo is unavailable at your destination port. For cost-saving, some buyers choose containerization, which requires disassembling the boom, arm, and cabin to fit into a 40ft HC container; however, you must factor in the re-assembly costs and potential for seal damage during this process.

Only deal with Audited Suppliers on Made-in-China.com who have a proven track record of exporting heavy machinery. Use Letter of Credit (L/C) for large transactions to ensure the bank only pays when the bill of lading is presented. Ensure the Sales Contract explicitly states the Engine Serial Number and Chassis Number to prevent the supplier from swapping the machine before shipment.
