2020 Caterpillar 312C
Product Description
Built for serious excavation work, this 2020 Caterpillar 312C delivers proven 12-ton class performance at a fraction of new equipment cost. Powered by a Caterpillar 3046T six-cylinder water-cooled engine producing 70.1 kW at 1,950 RPM, this machine combines reliable hydraulic muscle with efficient fuel consumption — making it a smart capital investment for contractors who demand output without overpaying.
Currently located in Guangdong, China, this unit is ready for inspection and export. Key performance specifications include:
- Bucket digging force: 62 kN | Rod digging force: 96 kN
- Maximum digging depth: 5,550 mm | Maximum excavation radius: 8,175 mm
- Maximum excavation height: 8,475 mm | Maximum unloading height: 6,095 mm
- 0.55 m³ backhoe bucket with 4,650 mm boom and 3,000 mm arm
- Main hydraulic pressure: 34.3 MPa | Main pump flow: 126.8 L/min
- Travel speed: 3.4 / 5.5 km/h | Climbing ability: 70% (35°)
- Fuel tank: 250 L | Hydraulic system capacity: 162 L
- Transport dimensions: 7,570 mm (L) × 2,590 mm (W) × 2,760 mm (H)
Compared to purchasing new, this 312C offers equivalent digging capability and hydraulic performance at significantly reduced acquisition cost — freeing capital for fleet expansion or project operations.
