卡特 320D2L

Standard and Optional Buckets Standard Bucket: Typically equipped with a standard backhoe bucket with a capacity of approximately 1.4 - 1.6 m³, suitable for general earthmoving and excavation. Optional Range: Depending on working conditions, buckets of various capacities can be fitted, ranging from 0.64 m³ to 1.75 m³, to handle everything from light materials to heavy-load mining operations. Hydraulic Breaker One of the most common attachments. Used for breaking hard rock, concrete pavements, or for secondary crushing in mining operations. Hydraulic Scrap Grapple / Grab Used in scrap steel processing, timber handling, or waste sorting. Replaces the bucket to achieve grabbing and loading functions. Rock Cutter / Trencher Used to cut narrow, straight trenches in hard rock. Commonly used for slope trimming or pipeline installation.

The CAT 320D2L is a classic 20-ton medium hydraulic excavator with LC long undercarriage manufactured by Caterpillar of the United States, and a benchmark second-hand machine widely circulated for earthmoving and mining projects across the globe. It features three core advantages: a durable self-developed Cat C7.1 six-cylinder engine, high-efficiency energy-saving electronically controlled hydraulic system, and long track undercarriage with superior stability, consistently earning leading recognition in overseas markets. It is suitable for all types of heavy-duty construction work, including highway foundation excavation, municipal pipeline installation, urban village renovation, building foundation construction, river dredging, sand yard material handling, small open-pit mining stripping, and rock crushing. The long track undercarriage offers a larger ground contact area, delivering remarkable stability on muddy riverbanks and gravelly steep slopes to prevent tail lifting and tipping over during operation. The mechanical direct-injection C7.1 engine boasts an extremely low failure rate and maintains steady power output during long-term operations in high/low temperature, high-altitude and heavily dusty sites, with excellent compatibility with low-grade poor-quality diesel. Caterpillar operates a comprehensive global network of authorized spare parts warehouses with readily available wear parts for engines, hydraulic components and undercarriages, keeping maintenance costs manageable. The machine’s booms and sticks are constructed with thickened wear-resistant steel plates and integrated robotic welding to resist deformation, making it the top balanced flagship 20-ton excavator of choice for overseas small and medium-sized construction contractors and equipment rental firms.
