2020 Caterpillar 312C











Product Description
This used 2020 Caterpillar 312C hydraulic excavator is offered ex-stock from our yard in Guangdong, China. A 12-ton class machine, it is a practical fit for general earthmoving, trenching, utility and site-preparation work where manoeuvrability and fuel economy matter more than maximum digging capacity.
The unit is available for trial — 任试 — allowing serious buyers to run it under load before any commitment is made.
Condition points for review:
- Undercarriage, hydraulic pump and cylinders, engine and cab inspected before listing; machine hours and available service records supplied on request; photographs and running video issued to qualified buyers; third-party inspection or in-person viewing arranged at our yard; loading and export documentation handled through our own desk at Guangdong ports.
Specifications are recorded as they stand for this individual unit. Buyers are encouraged to verify configuration, attachments and condition against the machine itself, and to confirm suitability for their own application before purchase. Pricing and availability on enquiry.
