Very Popular Second-hand Machine CAT312D2GC

The CAT 312D2GC excavator offers excellent fuel economy, stable and reliable performance, and easy and comfortable operation. The advantages are as follows: Efficient and Fuel-Efficient Advanced Engine: The Caterpillar 3054C direct-injection engine meets U.S. EPA Tier 2 and EU Stage II emission standards. Equipped with a proven mechanical governor and low-pressure fuel injection system, it improves fuel system durability, enhances fuel efficiency, and facilitates troubleshooting. Reduced Fuel Consumption: Rated at 56 kW net power, this engine was designed with fuel economy in mind, resulting in an estimated 14% reduction in fuel consumption compared to previous models. Stable and Reliable Performance Efficient Hydraulic System: The hydraulic system features a high-efficiency and high-performance design. The auxiliary hydraulic system and electrical wiring are routed to the boom mount, simplifying hydraulic circuit installation. The compact design utilizes shorter lines, reducing friction and pressure drop, and enabling more efficient use of power. Energy-Saving Regeneration Circuit: The boom and stick regeneration circuits conserve energy during boom-down and stick-retract operations, improving efficiency and reducing operating costs. Robust and Durable Structure: Over 70% of structural welding is performed by robots, resulting in stronger weld penetration than manual welding. The X-shaped box-section vehicle body offers excellent torsional resistance, and the track roller frames are pressed pentagonal components for high strength and long service life.
