Designed for light‑to‑medium heavy continuous‑duty work, it balances stable digging power, precise electro‑hydraulic control and cost‑effective design. It adapts to earthmoving, excavation, material loading and site development tasks, widely used in infrastructure construction, municipal engineering, quarry auxiliary work, water conservancy projects and general building sites. As the high‑volume cost‑effective core model in CAT medium excavator lineup, the 320GC delivers stable output, reduced maintenance expense and excellent return‑on‑investment for various general engineering projects.

Core Advantages

1. Reliable Power Performance & Outstanding Fuel Economy

Powered by mature CAT C4.4 diesel engine, net power 109.1 kW (146 hp), matching optimized low‑speed power tuning. It provides steady power output while cutting fuel consumption significantly. Intelligent engine management system automatically adjusts power according to real‑time working conditions to balance productivity and energy‑saving. Large 345 L fuel tank supports long continuous working hours and reduces downtime for refueling. Operating weight reaches 20600 kg, offering solid digging and loading capacity for daily earth‑rock working conditions.

2. Advanced Electro‑Hydraulic System & Excellent Working Parameters

The CAT 320GC adopts advanced electronic controlled load‑sensing hydraulic system. Flow and pressure are accurately matched to minimize invalid energy loss, achieving faster response, smoother compound movements and higher operation precision.

Key working parameters in the same tonnage segment:

• Maximum digging depth: 6630 mm
• Maximum ground‑level reach: 9430 mm
• Maximum dumping height: 6470 mm
• Standard bucket capacity: 1.1 m³
• Main hydraulic system pressure: 35 MPa
• Main pump maximum flow: 442 L/min

Equipped with two‑speed travel system and reinforced driving unit, it adapts to slopes, muddy ground and uneven construction sites. Heavy‑duty full‑sealed undercarriage resists dust, sediment and corrosion to extend service life of track shoes, rollers and other wearing components.

3. Human‑Oriented ROPS Cab & Full‑Scenario Safety Configuration

The enclosed cab meets ROPS/FOPS international roll‑over and falling‑object protection standards. Ergonomic interior layout with upgraded multi‑function joysticks reduces operator fatigue during long‑shift operation. Large‑view tempered glass plus rear‑view camera delivers panoramic visibility. Touch‑screen monitor shows real‑time machine data and fault self‑diagnosis alerts. Efficient vibration‑damping and noise‑reduction structure lowers interior noise level. Adjustable suspension seat and optional automatic air‑conditioning create comfortable working environment under high‑temperature or cold weather. Safety belts, working lamps and multiple warning sensors are standard equipped.

4. Reinforced Structure & Lower Maintenance Cost

Whole machine adopts high‑strength wear‑resistant steel. Boom, stick and chassis key stress parts are structurally reinforced for good anti‑impact and anti‑torsion performance, coping with earthwork and mild rock conditions. Upgraded sealing for hydraulic pipelines and joints effectively prevents oil leakage and sediment invasion. Centralized ground‑level service points for filters, oil ports and inspection openings shorten daily maintenance time and labor cost. Extended synchronized service intervals cut comprehensive ownership cost. Thanks to CAT proven industrial design, 320GC features low failure rate and high machine attendance rate.

5. Rich Attachment Compatibility & Wide Working Condition Adaptability

Quick coupler supports fast replacement of different working tools to realize multi‑scene operation:

• Standard digging bucket, heavy‑duty bucket and rock bucket
• Hydraulic breaker for concrete demolition and light rock breaking
• Hydraulic thumb / grapple for bulk material and scrap handling
• Auger for foundation hole and pile drilling
• Rake and grading bucket for site leveling and trench finishing

Diversified attachments allow flexible switch between excavation, loading, demolition and land‑finishing work to maximize equipment utilization rate.

Typical Application Scenarios

1. General Infrastructure ConstructionHighly applied in highway, railway, bridge and building foundation projects for earth excavation, embankment filling and site leveling. Reliable performance shortens construction cycle for medium‑scale projects.
2. Municipal Engineering & Urban RenewalRoad reconstruction, pipeline trenching, residential area development, partial building demolition. Balanced power and flexible movements fit complex urban construction environment.
3. Quarry & Material Yard Auxiliary OperationQuarry material loading, stockyard stacking, slag cleaning. Capable of cooperating with medium‑size transport trucks for efficient loading tasks.
4. Water Conservancy ProjectsRiver dredging, reservoir excavation, dike reinforcement. Good stability on wet and muddy terrain meets general water‑project operation requirements.
5. Land Development & Rental BusinessIndustrial park site preparation, farmland regulation and various rental‑oriented jobs. Low hourly cost makes it popular for equipment rental companies.
