Used CAT312D2GC Excavator Machinery 

The CAT312D2GC excavator offers excellent fuel economy, stable and reliable performance, and easy and comfortable operation. The advantages are as follows: Excellent Fuel Economy Efficient and Durable 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. The combined primary filter, oil-water separator, and secondary filter provide exceptional filtration performance, contributing to improved fuel filtration system reliability. Significantly 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 highly efficient and high-performance design. The auxiliary hydraulics and electrical wiring are routed to the boom frame, simplifying hydraulic circuit installation. The compact design utilizes shorter lines, reducing friction and pressure drop for more efficient power utilization. The hydraulic cross-sensing system utilizes two hydraulic pumps, enabling faster implement speeds and quicker, more powerful pivot rotations, improving productivity. Rugged and Durable Structure: The X-shaped box-section body provides excellent torsional resistance, and the track roller frames are pressed pentagonal components for strength and long service life. Over 70% of the structural welds are performed robotically, resulting in higher weld penetration than manual welding. Grease-lubricated track seals protect the track links, ensuring longer wear on the track link pins and bushings. Powerful Digging Force: With an operating weight of 12,500 kg and a standard bucket capacity of 0.53 m³, the bucket digging force is 95 kN, and the arm digging force is 65 kN, making it capable of easily tackling soil and rock of varying hardness. Easy and Comfortable Operation Simple operating modes: Switching between work and power modes is eliminated, ensuring maximum power at all times. Automatic boom and swing priority automatically selects the optimal mode based on joystick movement, eliminating the need for operators to learn different modes and simplifying operation. Comfortable and Convenient Cab: The well-designed cab, with an overall height of 2670mm, provides a spacious cabin, allowing easy entry and exit while maintaining good visibility. Commonly used switches are conveniently located, and the console and armrests are designed for comfort and adjustability. A standard mechanical suspension seat or an air suspension seat with a heater is available.
