2011 Caterpillar 312D
Product Description
Secure proven excavation power without the premium price tag. This 2011 Caterpillar 312D delivers 72kW of reliable C4.2 ACERT engine performance, handling demanding jobs with a 0.52m³ bucket capacity and 12-ton operating weight. Originating from Xuzhou's quality manufacturing, this joint venture machine offers the durability you expect from Caterpillar at a fraction of new equipment costs.
Performance specifications justify the investment: 96kN bucket digging force, 8,430mm maximum excavation radius, and 5,840mm digging depth tackle substantial earthmoving tasks efficiently. Water-cooled operation and a 250L fuel tank ensure extended productivity on remote job sites across challenging terrain—proven by its 70% grading capability.
Key investment advantages include:
- Hydraulic system capacity of 162L supporting consistent operation
- Compact transport dimensions (7,590mm length) for easy mobilization
- Dual travel speeds (3.4/5.5 km/h) optimizing site maneuverability
- 127 L/min main pump flow maintaining cycle times
- Currently located in Yunnan for immediate regional deployment
