Brand: CAT (Caterpillar Inc.) – A global benchmark in the heavy machinery industry with over a century of manufacturing expertise, renowned for its robust product durability, cutting-edge engineering technology and a comprehensive global after-sales service network. Cat® excavators are trusted by construction teams worldwide for their exceptional performance in extreme working conditions, and the 320 series, as the core of Cat's 20-ton class medium excavator lineup, has become a preferred choice for overseas engineering projects due to its balanced performance and cost-effectiveness.
Model: CAT 320GX – A new classic 20-ton hydraulic excavator launched by Cat for the global mid-market, equipped with the Cat C4.4 National IV emission-standard engine and an advanced electro-hydraulic control system. It abandons the need for Diesel Exhaust Fluid (DEF) and features
15% fuel savings and
20% lower maintenance costs compared to previous models like the 320D2 GC
Cat. With its high efficiency, low operating costs and compliance with international emission standards, it is tailored for overseas users engaged in earthmoving, municipal construction and small-scale mining operations, especially favored in Southeast Asia, Africa and the Middle East markets.
The 320GX is powered by the Cat C4.4 turbocharged engine with a rated power of 105.6kW (142hp) and a displacement of 4.4LCat. This engine adopts a high-pressure common rail fuel injection system and a maintenance-free DPF (Diesel Particulate Filter) with "无感 regeneration" (unnoticeable regeneration), eliminating the need for urea solution and downtime for regeneration. It meets China's National IV non-road emission standards and can use B20 biodiesel, adapting to the fuel quality requirements of most overseas regionsCat. The engine also features a -25°C cold start capability and 52°C high-temperature operation resistance, ensuring stable performance in extreme climates such as cold regions in Northern Europe and hot deserts in AfricaCat.
Equipped with an intelligent electro-hydraulic main control valve and optimized Smart mode logic, the 320GX achieves synergy between the engine and hydraulic system, reducing fuel consumption while maintaining fast cycle timesCat. The system cancels the pilot pump, cutting energy loss and oil leakage risks, and the automatic hydraulic oil preheating function accelerates machine startup in cold weather, extending component life. With a standard bucket capacity of 0.93m³ and a maximum digging depth of 6430mm, it delivers a bucket digging force of 136kN, ensuring high efficiency in earthmoving, loading and foundation excavation.
The front-end working devices (boom, arm and bucket linkage) are internally reinforced with high-strength steel, and the cast power linkages enhance wear resistance. The Cat chassis features sealed lubricated track pins and a heavy-duty undercarriage, absorbing job site vibrations and reducing track wear, with a service life extended by 50% compared to conventional designsCat. Maintenance is made easy with:
- Ground-level access to daily checkpoints (hydraulic oil level, coolant, fuel water separator)
- 1000-hour fuel filter replacement interval and 3000-hour hydraulic oil filter interval (doubled from previous models)
- Elimination of pilot filters and drain filters, cutting maintenance labor by 30%
The cab features an 8-inch high-resolution touchscreen monitor with multilingual support and a QR code-linked operation video library, enabling intuitive navigation and quick troubleshootingCat. The ergonomic suspension seat, low-noise design (≤75dB) and automatic climate control reduce operator fatigue during long shifts. Safety upgrades include:
- Ultra-wide field of vision with slim cab pillars and large windows, reducing blind spots
- Optional rearview camera and anti-slip maintenance platforms
- Fire-retardant wiring harnesses and waterproof electrical connectors, suitable for harsh overseas working environments
With transport dimensions of 9570mm×2800mm×2950mm and a rear swing radius of only 2830mm, the 320GX is compact enough for narrow urban construction sites. The anti-corrosion yellow paint resists salt spray in coastal areas and sand abrasion in deserts, while the modular design allows easy disassembly for container shipping.
The Cat C4.4 engine and electro-hydraulic main pump are neatly arranged in the engine compartment for optimal heat dissipation. The maintenance-free DPF and sealed hydraulic pipelines eliminate oil leakage risks, and the GPS positioning device complies with international environmental regulations for real-time emission data monitoring.
The 0.93m³ anti-adhesion bucket reduces material sticking, improving unloading efficiency by 5%. The reinforced boom and arm feature internal stiffeners, with a maximum digging height of 9290mm and unloading height of 6450mm, suitable for deep foundation pit excavation and high-altitude loading.
The spacious cab is equipped with a shock-absorbing seat, Bluetooth radio and 24V USB charging ports, creating a comfortable working environment for operators in high-temperature overseas regionsCat. The touchscreen monitor displays real-time engine speed, hydraulic pressure and fault codes, with a password-locking function to prevent theft.
The CAT 320GX, with its low operating costs and strong adaptability, is ideal for various overseas medium-sized engineering projects:
- Urban & Municipal Construction: Suitable for road repair, pipeline laying, community greening and small building demolition. Its compact rear swing radius avoids collisions with surrounding structures in narrow urban spaces.
- Earthmoving & Foundation Engineering: Competent for farmland renovation, river dredging and solar power foundation construction. The fuel-efficient engine and large bucket capacity reduce operation costs for large-scale earthmoving projects.
- Small-Scale Mining & Quarrying: Handles surface soil stripping and gravel loading in small mines. The wear-resistant bucket and stable chassis ensure safe operation on uneven mine terrain, while the maintenance-free DPF minimizes downtime.
We provide one-stop cross-border procurement support for overseas users, addressing all concerns from inspection to after-sales:
- Comprehensive Equipment Inspection: For used 320GX units, we provide detailed test reports covering engine power, hydraulic pressure, track wear and working hour records, along with real-time operation videos and third-party inspection support.
