2012 Caterpillar 320D

Engineered for demanding excavation operations, this 20-ton hydraulic excavator delivers exceptional performance through proven Caterpillar technology. Powered by the robust C6.4 ACERT engine generating 103 kW at 2000 rpm, this 320D model combines a 6.37-liter displacement with water-cooling efficiency to maintain consistent output across extended work cycles. The 6-cylinder configuration ensures smooth operation while meeting rigorous productivity standards.

Hydraulic superiority defines this machine's operational capability. With a main pump flow of 205 l/min and working circuit pressure of 35 MPa, operators command impressive digging forces: 140.1 kN bucket force and 106.4 kN rod force. The 5700mm boom and 2900mm rod configuration achieve a maximum digging depth of 6710mm and excavation radius of 9850mm, providing extensive reach for diverse applications.

Key technical specifications include:

• Operating weight: 20,930 kg with 1.0 m³ bucket capacity
• Travel speeds: 3.5/5.7 km/h with 70% gradeability
• Compact transport dimensions: 9460mm length × 2800mm width
• 410L fuel capacity for extended operation
