2013 Caterpillar 312D2GC
Product Description
Built for productivity, this 2013 Caterpillar 312D2GC excavator delivers 12 tons of proven performance across demolition, trenching, and earthmoving applications. Powered by a reliable Caterpillar 3054C engine producing 59kW, this water-cooled machine combines 95kN bucket digging force with 65kN stick force to handle demanding site conditions without hesitation.
Operational specifications include:
- Working weight: 12,500kg with 0.53m³ bucket capacity
- Maximum digging depth of 5,540mm and reach extending to 8,180mm
- Hydraulic flow rate of 232L/min for responsive cycle times
- Compact footprint: 2,490mm width navigates confined jobsites
- 250L fuel tank supports extended operating shifts
Currently located in Changsha, Hunan, this joint-venture manufactured unit features robust hydraulic circuits rated to 35MPa and 11.2rpm swing speed for efficient material handling. Transport dimensions of 7,610mm length and 2,830mm height simplify relocation between projects. Ready for immediate deployment on excavation, grading, or utility installation tasks.
