2016 Caterpillar 312D
Product Description
Engineered with Caterpillar's proven C4.2 ACERT engine delivering 72kW at 2200 rpm, this 312D excavator combines robust hydraulic performance with reliable mechanical design. The advanced hydraulic system operates at 3.05 MPa working pressure with a 127 L/min main pump flow rate, ensuring consistent power delivery across demanding applications.
Built on a 12.9-ton platform, this machine features precision-engineered components including a 0.52m³ bucket capacity and impressive digging forces of 96kN bucket and 62kN rod strength. Water-cooled 4.25L displacement engine provides optimal thermal management, while the comprehensive hydraulic circuit design maintains operational efficiency under heavy loads.
- Maximum digging depth: 5,840mm with 8,430mm reach radius
- Dual travel speeds: 3.4/5.5 km/h for versatile mobility
- 70% climbing capability on 35° gradients
- 500mm track plates with 2,780mm ground contact length
- 250L fuel capacity for extended operation cycles
Located in Guangdong Maoming, this 312D represents Caterpillar's commitment to engineering excellence in the mid-size excavator segment.
