2012 Caterpillar 312D
Product Description
Engineered with Caterpillar's proven C4.2 ACERT engine delivering 72kW at 2200 rpm, this 2012 312D excavator represents joint-venture manufacturing excellence from Xuzhou. Water-cooled reliability combines with a 4.25L displacement to power through demanding earthmoving operations with consistent performance across varied terrain.
Hydraulic superiority defines this 12-ton machine. The main pump flows 127 l/min through a robust 3.05 MPa working circuit, translating into 96kN bucket digging force and 62kN rod force—critical metrics for production-focused contractors. A 162-liter hydraulic system capacity ensures sustained operation without thermal fade.
Core Specifications:
- Operating weight: 12,920 kg with 0.52 m³ bucket capacity
- Maximum digging depth: 5,840 mm; reach: 8,430 mm
- Boom/rod configuration: 2,800 mm / 3,000 mm
- Travel speeds: 3.4 / 5.5 km/h with 70% gradeability
- Fuel autonomy: 250L tank for extended shifts
Currently located in Shenzhen, Guangdong, this water-cooled excavator maintains the dimensional discipline Caterpillar is known for: 7,590 mm transport length, 2,590 mm width. Ready for immediate deployment in infrastructure, u
