This high-quality used Caterpillar 330D excavator is a classic heavy-duty 33-ton crawler digger widely trusted for large-scale earthmoving, quarry mining, foundation excavation, road construction, and infrastructure projects worldwide. Famous for its robust structure, stable hydraulic performance, and long service life, the second-hand Cat 330D remains one of the most cost-effective heavy excavators for global construction buyers.

This Cat 330D excavator features a standard operating weight of 33.75 tons and a flexible bucket capacity ranging from 1.4 m³ to 2.0 m³, with a standard 1.8 m³ bucket for high-efficiency bulk material handling. Equipped with a 6.5 m boom and 3.2 m stick, it delivers extended working coverage and powerful digging ability. Its standard 700 mm track shoes ensure stable ground contact and excellent adaptability on uneven construction sites. The overall transport dimension is 11,150 × 3,190 × 3,340 mm, convenient for shipping and site transfer.

Powered by the original Cat C9 ACERT inline 6-cylinder water-cooled turbocharged diesel engine, this used Cat 330D provides a maximum rated power of 200 kW (270 hp) at 1800 rpm. With an 8.8 L displacement and 110 × 127 mm bore-stroke design, the engine outputs strong torque reserve, ensuring stable power delivery under continuous heavy-load working conditions. Matched with a large 620 L fuel tank, 175 L hydraulic tank, 40 L engine oil capacity and 40 L coolant capacity, the machine supports long-hour non-stop operation and reduces daily maintenance frequency.
