Used Komatsu PC300-7 excavator
A 30-40t class Komatsu machine for export from China. Price follows the exact unit, not the model name.




Komatsu PC300-7 is not a machine we push to every buyer. It is mainly for used machinery dealers, small trading companies and regional agents who need lower entry cost, simple local repair and fast resale in price-sensitive markets. For African inland dealers, this model is often easier to move than a newer PC300-8 because the buying cost is lower and local mechanics understand it better.
The same logic also fits other markets where buyers care more about repair cost and machine price than emission documents. PC300-7 fits ordinary earthmoving, road work, land clearing, short-term construction and small quarry support. It is a good choice when the downstream customer cares more about working condition, parts supply and repair cost than electronic management or long-term fuel saving.
For hard rock every day, long breaker work or high-temperature heavy loading, we would not push PC300-7 as the first choice. In those jobs, check PC300-8 or a heavier Komatsu model after seeing real working video. If your market requires Tier 3 or Stage IIIA import clearance, confirm local rules before choosing PC300-7.
We usually keep around 3 flowing units. Stock changes quickly. Most available units are repainted before export because many dealers want cleaner appearance for resale. Original paint units may be available sometimes, but we do not promise that before checking current stock.
Many PC300-7 units we handle come with new or around 80% track chains and track shoes. Still, paint is not condition. Paint helps resale, but video proves the machine. A low meter hour does not equal a good PC300-7. A lower PC300-7 price is not always a better deal if the undercarriage, hydraulic movement or structure needs repair.
As a used machinery exporter from China, we suggest buyers confirm the exact unit before paying, not only the model name. Before payment, check the current yard video, cold start, hydraulic movement, walking video, undercarriage photos, machine plate and loading proof. Send us your target market and job type, and we will help check whether PC300-7 or PC300-8 is safer for your customer.
