2016 Caterpillar 312C
Product Description
Built for medium-duty excavation, this 2016 Caterpillar 312C delivers 70.1 kW of proven power across construction and earthmoving applications. Currently located in Guangxi, this 12-ton excavator combines a 4650mm boom with a 3000mm stick to achieve a maximum digging depth of 5550mm and an excavation radius of 8175mm—ideal for foundation work, trenching, and site preparation tasks requiring precision reach.
Powered by a reliable 3046T water-cooled engine with 4.3L displacement, the machine generates 96 kN of stick digging force and 62 kN of bucket force to break through compacted soil and rocky substrates. The 0.55m³ bucket capacity balances productivity with cycle speed, while dual travel speeds (3.4/5.5 km/h) optimize movement between dig zones. Hydraulic flow peaks at 126.8 L/min through a 34.3 MPa system, ensuring responsive control during loading and grading operations.
Key Specifications:
- Operating weight: 12,777 kg with 500mm track plates for stable ground pressure
- Maximum excavation height: 8475mm for truck loading efficiency
- 250L fuel tank and 150L hydraulic reservoir for extended shifts
- Transport dimensions: 7570mm × 2590mm × 2760mm
