Caterpillar® 320BL Hydraulic Excavator (with 3066 Engine)

A Legacy of Strength, Re-engined for Enhanced Performance

The Caterpillar 320BL is a legendary mid-size excavator celebrated for its robust frame, exceptional durability, and straightforward design. This particular configuration, powered by the modern Cat C4.4 (3066) turbocharged diesel engine, represents a significant upgrade, marrying the classic 320BL's bulletproof reliability with improved fuel efficiency, lower emissions, and greater horsepower. It remains a top-tier choice in the used market for owners seeking a cost-effective, powerful, and reliable machine for demanding applications.

Power & Efficiency: The Heart of the Machine

• Advanced Cat C4.4 (3066) Engine: This engine is a key differentiator. Replacing the earlier 3054 series, the 4.4-liter 3066 engine delivers more power and torque, leading to faster cycle times and better performance in tough digging conditions. It is designed for superior fuel efficiency and meets stricter emissions standards (Tier 2/Stage II), making it more sustainable and often easier to permit for various worksites.

• Intelligent Hydraulic System: The 320BL features a high-pressure, variable-flow hydraulic system that provides responsive, smooth control. The system automatically matches hydraulic flow to demand, optimizing performance while minimizing waste and heat generation.

Built for Durability & Productivity

• Proven Mainframe & Undercarriage: The 320BL is famous for its incredibly strong X-shaped mainframe and durable undercarriage components. Built to withstand high-stress twisting forces, this design ensures long-term structural integrity and stability, which is critical for lifting and heavy digging.

• Excellent Digging Forces: Equipped with powerful hydraulic cylinders and optimized linkage geometry, the 320BL delivers outstanding bucket and stick digging forces, allowing it to tackle hard clay, rocky soils, and other challenging materials.

• Operator-Focused Environment: The comfortable, spacious cab (ROPS/FOPS certified) offers excellent visibility, low sound levels, and intuitive pilot-controlled hydraulics, reducing operator fatigue and boosting productivity over long shifts.

Why Choose a Used 320BL with a 3066 Engine?

• Optimal Balance of Cost & Capability: You acquire the renowned durability of the 320B series chassis at a fraction of the cost of a new machine, now enhanced with a more modern and efficient powerplant.

• Enhanced Performance: The 3066 engine provides a noticeable power advantage over earlier 3054-powered models, translating directly to faster digging and loading cycles.

• Improved Operating Economics: Better fuel efficiency and potentially lower maintenance costs associated with the newer engine design contribute to a lower total cost of ownership.

• Unmatched Parts & Service Support: As a Caterpillar product, the 320BL is supported by a global network of dealers. Parts availability for both the chassis and the ubiquitous 3066 engine is excellent, ensuring maximum uptime.
