Ask for current stock, real machine video, specs, weight, transport size, hydraulic test and export support before quotation.
The Caterpillar CAT 320B is an older used 20-ton class excavator for buyers who want lower buying cost and can accept age, inspection and local repair responsibility. Before comparing price, check cold start, hydraulic response, undercarriage wear, machine plate, weight and same-machine loading proof. CAT 320BL long-undercarriage stock can also be checked separately.
If you are checking a used Caterpillar CAT 320B, you already know this is not a new-generation excavator. You want an older 20-ton class machine with lower buying cost, easier old-machine repair in many local markets and enough remaining working life. The price only makes sense when the cold start, engine sound, hydraulic response, travel condition, undercarriage wear, machine plate and same-machine loading proof support the quotation.
For a used Caterpillar 320B, the buyer should focus on engine condition, hydraulic pump response, old wiring, monitor display, undercarriage wear and structure condition. Do not judge an old CAT 320B only by yellow paint, year or hour meter. A clean repaint does not prove the engine is healthy, the pump is strong or the undercarriage still has enough life.
Compared with CAT 320C or 320D, the 320B is usually chosen for lower buying cost and simpler older-machine repair, not for newer comfort, newer electronic systems or better fuel economy. If your local market can still repair old Caterpillar machines and your import rules allow this age of equipment, a good-condition 320B can still be practical. If you need a newer machine with higher comfort and easier resale to modern fleets, 320C or 320D may be better to compare.
If you need long-undercarriage stock, we can also check available CAT 320BL machines. For 320BL, we still confirm the real configuration by machine plate, undercarriage video, track frame details and travel test before quotation.
Two used CAT 320B machines can have very different value. One may be cheaper because the hydraulic pump is tired, the swing has abnormal noise, the undercarriage needs repair or the engine smokes after warm-up. Another may cost more but save you money after arrival. For this model, compare the real machine condition, not only the number on the quotation.
Before payment, ask for current stock photos, cold start video, engine sound, hydraulic test, swing test, walking test, undercarriage video, machine plate, engine plate and loading proof. For export buyers, the machine prepared for loading should match the machine shown in the inspection video.
General CAT 320B specifications are useful for comparison, but a used machine should always be confirmed by the actual unit. Weight, engine model, undercarriage type, bucket size, hydraulic condition and transport size can change by configuration, repair history and attachments.
| Specification Item | What to Confirm |
| Caterpillar CAT 320B Model | Confirm real model by machine plate |
| CAT 320B Weight | Confirm actual operating weight by current machine configuration |
| Caterpillar 320B Engine | Confirm engine model by engine plate and cold start video |
| Hydraulic Pump | Check pump response, leakage, abnormal sound and working speed |
| Monitor / Electrical System | Check old monitor display, warning lights, dead pixels, alarms and wiring harness condition |
| Undercarriage | Check rollers, sprocket, track shoes, track frame and final drive area |
| Swing System | Check swing response, swing brake, abnormal noise and swing bearing movement |
| Bucket & Pins | Check bucket size, bucket pins, bushings and welding condition |
| Transport Size | Confirm width, height, bucket position and loading method before shipment |
| CAT 320BL Stock Option | If needed, confirm long-undercarriage stock by machine plate and undercarriage video |
| Import Details | Confirm year, documents and local import age rules before booking shipment |
Specs should help you avoid wrong expectations. They should not replace real inspection video, because two old CAT 320B excavators can be very different in condition.
The CAT 320B is suitable for buyers who want a Caterpillar 20-ton class excavator at a lower buying cost than newer CAT 320C, 320D or later models. It is not the right choice if you only want a newer cabin, newer electronics or low-risk resale.
Many mechanics in developing markets are familiar with older Caterpillar machines. This can help when local repair support matters more than newer machine comfort. Still, the engine, hydraulic pump, monitor, wiring and undercarriage must be checked before payment.
If your job needs better stability for grading, trenching or uneven ground work, we can also check current CAT 320BL long-undercarriage stock. The actual track frame, rollers, sprocket and travel condition should be confirmed by video.
A clean repaint does not prove engine health, pump response, swing condition or walking strength. For an old Caterpillar 320B, cold start, smoke, hydraulic movement, swing, walking and undercarriage video are more important than yard photos.
Before shipment, confirm machine plate, engine plate, current weight, transport size, bucket, loading method and same-machine loading proof. For an older CAT 320B, age, condition and import rules can affect the final buying decision.
Check whether the engine starts normally, whether smoke is heavy, whether idle is stable, and whether abnormal engine noise appears after start.
Check rollers, sprocket, track shoes, final drive area, track frame wear and whether the machine travels straight.
Watch boom, arm, bucket, hydraulic pump response, swing movement, straight travel, travel speed and abnormal sound under real movement.
Confirm machine plate, engine plate, current stock photos, loading video and loading proof. The machine loaded should match the machine shown in the inspection video.
