Original Used CAT312D2 Excavator

The CAT 312D2 excavator offers powerful power, comfortable operation, and low maintenance costs, as follows: Superior Power and Performance Efficient and Reliable Engine: Equipped with a Cat 3054C direct-injection engine rated at 56 kW, it utilizes a proven mechanical governor and low-pressure fuel injection system, meeting U.S. EPA Tier 2 and EU Stage II emission standards. The fuel system is durable and easy to troubleshoot, resulting in approximately 14% reduction in fuel consumption compared to previous models. Stable and Efficient Hydraulic System: The hydraulic system features a high-efficiency and high-performance design. Auxiliary hydraulic lines and wiring are routed to the boom base, simplifying hydraulic circuit installation. The hydraulic cross-sensing system utilizes two hydraulic pumps, enabling faster implement speeds and quicker, more powerful pivot turns, improving productivity. Boom and stick regeneration circuits conserve energy, improve efficiency, and reduce operating costs. Excellent digging capabilities: With an operating weight of 12,500 kg, a bucket digging force of 95 kN, and an arm digging force of 65 kN, the machine can easily handle soil and rock of varying hardness. A travel speed of 5.1 km/h and a swing speed of 11.2 rpm ensure efficient operation. Comfortable and convenient operation The user-friendly cab design: The cab is spacious and comfortable, with an overall height of 2,670 mm, making entry and exit easy for the operator. The ergonomic design features a standard suspension seat with multiple adjustments, and the joystick is designed to align with the human body’s natural posture, effectively reducing operator fatigue. Intelligent operation: A full-color liquid crystal display (LCD) is adjustable to reduce sunlight glare and displays information in 27 languages, allowing the operator to easily understand machine status. Furthermore, switching between work and power modes is eliminated, and the automatic boom and swing priority function automatically selects the optimal mode based on joystick movement, making operation simpler and more convenient. Low Maintenance Costs Easy Maintenance: Over 70% of structural welds are performed robotically, resulting in stronger weld penetration than manual welding. The structural components and undercarriage are durable and have long maintenance intervals. Furthermore, auxiliary hydraulic lines and electrical wiring are integrated into the boom base, facilitating installation and maintenance of the hydraulic circuit. Major hydraulic components, electrical components, and other vulnerable parts are centrally located and easily accessible for removal and replacement, reducing maintenance time and costs. Durable Components: The track roller frames are extruded pentagonal components for strength and long service life. Grease-lubricated track seals protect the track links, ensuring longer wear on the track link pins and bushings. The boom and arm utilize corrosion- and wear-resistant, self-lubricating bearings for exceptional durability.
