Introduction
The Caterpillar 320 GC hydraulic excavator is a versatile and efficient machine designed for light to medium-duty applications. It offers a balance between performance, fuel efficiency, and low operating costs, making it a popular choice among contractors and operators worldwide.
Engine and Performance
At the heart of the 320 GC is the Cat® C4.4 engine, delivering a net power of 109 kW (146 hp) at 2,000 rpm. This engine is designed to meet EU Stage V emission standards and is compatible with up to B20 biodiesel, providing flexibility in fuel choices. The engine's design emphasizes low fuel consumption, with a combination of low engine speed and a large hydraulic pump contributing to reduced fuel usage. This setup helps operators achieve top performance while burning less fuel, leading to significant cost savings over time.
Hydraulic System
The 320 GC's hydraulic system is engineered for efficiency and precision. It features a maximum implement flow of 442 L/min (116 gal/min) and a maximum equipment pressure of 35,000 kPa (5,075 psi). This powerful hydraulic system ensures optimal performance in various digging and lifting tasks, enhancing productivity on the job site.
Dimensions and Weight
The 320 GC has an operating weight of 22,400 kg (49,400 lb) in its standard configuration, with 790 mm (31 in) triple grouser shoes, a reach boom, a 2.9 m (9'6") stick, and a 1.0 m³ (1.31 yd³) heavy-duty bucket. Its compact dimensions, with a transport length of 9.53 meters and a width of 3.17 meters, make it suitable for urban construction sites where space is limited.
Working Ranges
The 320 GC offers impressive working ranges, including:
Operator Comfort and Technology
The 320 GC is equipped with a spacious and comfortable cab, featuring low-effort joysticks, a large touchscreen display, and excellent visibility. The cab's design prioritizes operator comfort, reducing fatigue during long working hours. Additionally, the machine offers easy-to-use technology features, including multiple power modes to match specific applications and reduce fuel consumption.
Maintenance and Durability
Caterpillar has designed the 320 GC with durability and ease of maintenance in mind. The machine features extended and synchronized maintenance intervals, helping operators reduce maintenance costs by up to 20% compared to previous models. The consolidated filter locations and high dirt capacity hydraulic filters contribute to longer service life and reduced downtime.
Real-World Applications
The 320 GC is well-suited for various applications, including:
The Caterpillar 320 GC hydraulic excavator stands out as a reliable and efficient machine for light to medium-duty applications. Its combination of performance, fuel efficiency, and low operating costs make it a valuable asset for contractors seeking to maximize productivity and minimize expenses. With its advanced features and durable design, the 320 GC continues to be a preferred choice in the construction industry.
