Used CAT312D2GC Excavator 

The CAT312D2GC excavator offers excellent fuel economy, stable and reliable performance, and comfortable and convenient operation. The advantages are as follows: Fuel Efficiency: It utilizes the Cat 3054C direct-injection engine, which meets US EPA Tier 2 and EU Stage II emission standards. It features a proven mechanical governor and low-pressure fuel injection system. A combined primary filter, oil-water separator, and secondary filter enhance fuel filtration system reliability. With a rated net power of 56 kW, fuel consumption is approximately 14% lower than the previous model, resulting in excellent fuel economy. Stable and Reliable Performance Efficient Hydraulic System: The hydraulic system features a high-efficiency and high-performance design. Auxiliary hydraulics and electrical wiring are routed to the boom frame, simplifying hydraulic circuit installation. Hydraulic snubbers located at the rod end of the boom cylinder and both ends of the stick cylinder absorb shock, reduce noise, and extend cylinder life. Regenerative circuits in the boom and stick save energy, improve efficiency, and reduce operating costs. Robust and Durable Structure: The X-shaped box-section body offers excellent torsional resistance. Over 70% of the structural welds are performed robotically, resulting in stronger weld penetration than manual welding. The track roller frames are extruded pentagonal components for strength, and the tracks feature grease-lubricated seals to protect the track links. Comfortable and Convenient Operation The cab is spacious and ergonomically designed at 2670mm in height, with all switches conveniently located on the right-hand console. The standard suspension seat offers multiple adjustments, and wide armrests and seatbelts enhance comfort and safety. Easy Operation: The machine eliminates the need to switch between working and power modes, ensuring maximum power is always available. The automatic boom and swing priority function automatically selects the optimal mode based on joystick movement, simplifying operation. Advanced Monitoring System: The monitor features a full-color LCD, adjustable to reduce sun glare, displays information in 27 languages, and includes a built-in pre-start self-diagnosis function, ensuring the operator is fully informed of the machine’s status.
