卡特 320D

The Cat® 320D2 is a reliable 20-ton medium-sized crawler excavator, specifically engineered for heavy construction tasks, delivering excellent fuel efficiency and high productivity in truck loading, trenching, lifting and utility work. Powered by a Cat C7.1 mechanically governed engine, it provides 112 kW (150 hp) of net power (ISO 14396) and meets U.S. EPA Tier 3, EU Stage IIIA equivalent emission standards, with a low-pressure fuel system that ensures reliable performance even with lower-quality fuel supplies. Equipped with a high-efficiency main pump and eco mode, the 320D2 reduces fuel consumption without sacrificing lifting or digging power, while a variable-speed fan with viscous clutch further enhances fuel economy. Its advanced hydraulic system delivers precise control, and it is compatible with a full range of Cat attachments—including buckets, hydraulic hammers, grapples and shears—enabling versatility in construction, site preparation, road building, demolition and debris clearing. Designed for durability and easy maintenance, the 320D2 features a reinforced X-shaped frame, heavy-duty boom and arm, and lubricated track links that extend undercarriage life and reduce noise. Most maintenance points are accessible from ground level, with fuel filters reduced from four to two and extended 500-hour service intervals, significantly lowering operating costs. The ergonomically designed ROPS cab offers a spacious, quiet working environment with low-effort joysticks, adjustable suspension seats, excellent visibility and a full-color LCD monitor, minimizing operator fatigue and enhancing safety during long shifts. With an operating weight ranging from 21,100 kg to 22,300 kg, a maximum digging depth of 6720 mm and a bucket capacity of 1.0 to 1.3 m³, the 320D2 combines rugged performance, cost-effectiveness and ease of operation, making it an ideal choice for contractors seeking reliable equipment for tough job site conditions.
