Product Overview

The Caterpillar 320D2L is the long-undercarriage variant of the classic D2 series 20-ton medium hydraulic crawler excavator, purpose-engineered for soft ground, muddy terrain and low-bearing-capacity jobsites. Equipped with the original CAT C7.1 direct-injection turbocharged diesel engine and factory-calibrated load-sensing hydraulic system, the extended track frame delivers larger ground contact area, lower ground pressure and superior working stability, making it highly adaptable to harsh and soft site conditions.

Every pre-owned 320D2L excavator in our inventory has passed a rigorous 80+ point full-machine technical inspection and professional refurbishment. All units are guaranteed free of major structural accidents, retain 100% original factory core components, and come with traceable scheduled maintenance records. With excellent preserved performance and only 40%-60% of the cost of a new machine, it is a high-ROI choice for overseas construction contractors and equipment rental fleet operators, especially those serving soft-terrain and rainy-region projects.

Core Product Advantages

• Original Caterpillar C7.1 inline 6-cylinder direct-injection turbo engine, highly adaptable to high-sulfur and low-quality fuel, with stable 138HP output and extremely low long-term failure rate

• Factory-original CAT load-sensing hydraulic system with 35MPa working pressure, delivering precise control response and smooth compound movements for consistent digging efficiency

• Extended long undercarriage design with larger ground contact area and approx. 40kPa ground pressure, greatly improving passability and working stability on muddy, soft soil and swampy jobsites

• Heavy-duty X-shaped chassis frame and reinforced travel mechanism, with strong torsion and impact resistance, suitable for long-term heavy-duty operation on rough unpaved roads

• High-strength boom and stick manufactured with CAT's original robotic welding process, superior impact and fatigue resistance for heavy earthmoving and quarry operations

• Multi-stage fuel filtration system and optimized lubrication circuit, effectively protecting core components and significantly reducing daily operation and maintenance costs

• Verified accident-free condition with complete maintenance files; all core power and hydraulic parts remain original factory specifications. Ready in stock with 7-15 day fast delivery lead time

• Full one-stop export service covering pre-shipment inspection, complete customs documentation, global logistics arrangement and worldwide spare parts supply support
