卡特 CAT320GC

The Cat 320 GC is a medium-sized crawler excavator designed for light to medium-duty applications. It boasts low fuel consumption, low maintenance costs, and precise operation as its core advantages. It is mainly used for municipal, infrastructure, and general earthwork projects, while also balancing efficiency and economy. The working weight ranges from approximately 20.4 to 22.0 tons, and the standard bucket capacity is 1.0 m³. Power system: Cat C4.4e TA electronically controlled engine, with a net power of approximately 107–110 kW (143–147 hp). The low-speed large pump design reduces fuel consumption by about 20% compared to the previous model; three-stage fuel filtration, suitable for various oil qualities and -32°C low-temperature starting, and stable power on high altitudes. Hydraulic and operation: Main pressure 35 MPa, flow rate approximately 429 L/min; rotation speed 9–11.3 rpm, travel speed 5.5 km/h; maximum digging depth 6630–6720 mm, maximum loading height 6580 mm, bucket digging force approximately 170–180 kN, arm priority/rotation priority and regeneration circuit, fast circulation and precise control. Structure and maintenance: Driver's cab is spacious, has good visibility, and features low noise and shock absorption; maintenance intervals are extended, and maintenance costs are reduced by approximately 20–25%; standard broken pipe system for easy quick-change attachments. The Cat 320 GC focuses on "fuel efficiency, low maintenance, and precise operation", making it a cost-effective choice for light to medium-duty scenarios such as municipal, earthwork, and pipeline projects. If the work conditions involve rocks or require continuous heavy-duty operations, the standard version 320 or 323 is recommended. If necessary, I can provide more precise suggestions on attachments and models based on your specific work conditions (soil type, digging depth, daily work volume).
