2011 Caterpillar 312D
Descrição do Produto
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
