卡特 320D

The CAT320D used excavator boasts powerful performance, efficient hydraulics, controllable fuel consumption, and durable construction, making it widely applicable in medium-sized earthmoving, infrastructure, municipal, mining, and demolition scenarios. It is particularly suitable for continuous operations requiring high efficiency and reliability. Equipped with a CAT C6.4 ACERT engine, it delivers approximately 104–139 ​​kW (140–186 hp) with a high-pressure common rail and turbocharger, ensuring stable power output. The combination of low-speed and high-flow pumps reduces fuel consumption by approximately 10% compared to the previous generation; automatic idle further enhances energy efficiency. With a working pressure of 35 MPa (35000 kPa) and a main pump flow rate of approximately 429 L/min, the dual-pump synergy and PPPC load sensitivity result in smooth and responsive compound movements. The bucket digging force is approximately 150 kN, the stick approximately 106 kN, and the traction force approximately 206 kN, providing strong heavy-duty and climbing capabilities. High-strength steel and reinforced boom/stick provide outstanding fatigue and impact resistance. It can cold start at -18°C (optional -32°C kit) and operate stably in high-temperature environments up to 52°C, adapting to various climatic conditions. Large stock in the used market, readily available parts, high residual value, and controllable long-term costs. Suitable for medium-sized earthmoving projects, infrastructure construction, municipal engineering, mining and quarrying, agriculture, forestry and landscaping, forest clearing, land reclamation, and dam construction. Highly adaptable to various environments, balancing power and efficiency, and compatible with various attachments. The CAT320D used excavator, with its balanced performance in power, hydraulics, and durability, is a reliable choice for medium-sized projects.
