Ask for current stock, real machine video, specs, weight, transport size, hydraulic test and export support before quotation.
Hyundai R300LC-9S is a 30-ton Hyundai 9-series crawler excavator, also sold under Hyundai 300 / 305 naming in some export markets. We usually have around five moving-stock options in China. Before buying, confirm the actual plate, Cummins engine, undercarriage and current working video.
Hyundai R300LC-9S, 300-9S, 305-9S, R305LC-9S and R305LC-9T usually refer to the same 30-ton Hyundai 9-series machine under different regional naming. For quotation and inspection, we use R300LC-9S as the main reference name, while the final model must be confirmed by the actual machine plate.
For this model group, we usually have around five moving-stock options in China. Some machines are original paint, some are fully repainted, and some only have partial repainting. Meter hours often show around 3,000–8,000H for reference. Undercarriage condition also varies, from around 80% to newer or newly replaced undercarriage, depending on the unit.
The real selling point is the Cummins C8.3-C mechanical direct-injection platform. It has no high-pressure common rail system, and many local repair shops in low-emission-control markets are more familiar with Cummins C-series engines. For buyers who care about repair convenience and lower entry cost, this model can make more sense than a higher-priced Japanese 30-ton machine.
Do not place this model in the wrong market. It is not a good fit for markets where import clearance requires official EPA Tier 3 or stricter emission documents. It is also not the best choice for high-end rental fleets, daily hard rock mining, or buyers with no basic electrical repair ability. Repainting, breaker piping, breaker hammer or other attachments can be arranged before shipment if needed.
Final Hyundai R300LC-9S specs should be confirmed by the current machine, nameplate and engine plate. Factory parameters can be used as reference, but used machines may vary by bucket, track width, attachment setup, repainting level and undercarriage condition.
| Specification Item | What to Confirm |
| Model Version | Confirm R300LC-9S / 300-9S / 305-9S / R305LC-9S / R305LC-9T by real nameplate |
| Operating Weight | Around 30,200 kg for LC long-track configuration; confirm current unit |
| Engine | Cummins C8.3-C mechanical direct-injection type as factory reference; confirm actual engine plate |
| Power | Around 198 kW / 1900 rpm as factory reference; confirm current unit |
| Bucket Capacity | Standard around 1.38 m³; actual bucket may vary |
| Emission Level | Generally China Stage II-level; confirm local import rules before purchase |
| Hydraulic System | Check pump response, boom, arm, bucket, swing and combined movement |
| Undercarriage | Check rollers, sprocket, track chain, idler, track shoes and frame wear |
| Structure | Check boom, arm, bucket linkage, pins, welding marks and leakage |
| Transport Size | Confirm width, height, bucket / arm removal need, loading method and port limits |
The Cummins C8.3-C mechanical direct-injection platform is simpler than high-pressure common rail systems, more tolerant of lower-quality diesel, and easier for many local repair shops to handle. Confirm the actual engine plate in the video before purchase.
Buyers can choose between original paint, repainted and partially repainted units, with different meter hours and undercarriage conditions. The exact choice should follow the buyer’s budget, resale plan and job requirement.
Komatsu PC300-7 is stronger for resale value, and Hitachi ZX330-3G is usually better for heavy stone. Hyundai R300LC-9S should be chosen when the buyer wants lower entry cost, Cummins repair convenience and 30-ton earthmoving value.
Hyundai R300LC-9S is more suitable for earthmoving, roadwork, loading, resale and mid-range contractor use. For daily hard stone, mining or heavy breaker work, a heavier-duty stone-focused machine may be safer.
Some buyers prefer original paint for condition judgment, while others need repainting for resale. We can arrange breaker piping, breaker hammer or other attachments, but paint should never replace cold start, hydraulic, undercarriage and same-machine proof.
Check smoke, idle stability, engine sound, engine plate and warm-up response. Do not judge only by meter hours.
Check display warnings, sensor response and visible wiring. Older 9-series machines can have sensor faults or brittle wiring.
Watch boom, arm, bucket, swing and combined movement under load. A good machine should move smoothly, not only move.
Check one-side travel, straight travel, rollers, sprocket, track chain, idler, track shoes, final drive area, boom, arm, pins and welding marks.
Confirm nameplate, engine view, current working video, identifiable photos, loading video and loading proof. The loaded machine should match the inspected machine.
