2013 Caterpillar 312D
Product Description
Powered by the proven C4.2 ACERT engine delivering 72 kW at 2200 rpm, this 2013 Caterpillar 312D represents benchmark engineering in the 12-ton excavator class. Water-cooled with a 4.25L displacement, the powertrain combines fuel efficiency with consistent performance across demanding applications. Hydraulic superiority defines this machine: a 127 l/min main pump flow drives a robust system with 96 kN bucket digging force and 62 kN arm digging force, enabling precise material handling in confined or open-site conditions.
- Operating weight: 12,920 kg with 0.52 m³ bucket capacity
- Maximum digging depth: 5,840 mm; maximum reach: 8,430 mm
- Dual travel speeds (3.4/5.5 km/h) for versatile site mobility
- 250L fuel tank and 162L hydraulic system for extended operation
- Compact transport dimensions: 7,590 mm (L) × 2,590 mm (W) × 2,970 mm (H)
- 70% gradeability (35°) for challenging terrain
Currently located in Shenzhen, Guangdong, this joint-venture manufactured unit maintains Caterpillar's reputation for durability and parts availability worldwide. Ideal for contractors requiring reliable mid-range excavation capacity with proven hydraulic technology.
