Product Overview

The Caterpillar 329D2L is a 29-ton class heavy-duty medium hydraulic crawler excavator from Caterpillar's proven D2 product line, featuring an extended long undercarriage for superior stability and low ground pressure. Engineered specifically for emerging markets with variable fuel quality, this model is powered by an original CAT C7.1 direct-injection turbocharged diesel engine with air-to-air aftercooling, paired with a factory-calibrated high-flow load-sensing hydraulic system with boom and stick regeneration circuits. It is also equipped with an Eco Mode that reduces fuel consumption by up to 11% without sacrificing digging and lifting force, delivering high production efficiency and low operating costs for heavy earthmoving, quarry loading and high-intensity construction applications.

Every pre-owned 329D2L excavator in our inventory has passed a rigorous 90-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 strong heavy-duty performance and significantly lower total investment compared to new machines, it is a high-ROI core asset for overseas medium and large construction contractors and professional equipment rental fleets.

Core Product Advantages

• Original Caterpillar C7.1 ATAAC direct-injection turbo engine, delivering stable 202HP power output with strong tolerance to high-sulfur and low-quality fuel, perfectly suited for long-hour heavy-duty operations in emerging markets

• Built-in Eco Mode and engine speed synchronization control, reducing fuel consumption by up to 11% with no loss of digging and lifting performance, effectively lowering daily operating costs

• Factory-calibrated high-flow hydraulic system with boom and stick regeneration circuits, shortening cycle times, reducing energy loss and improving overall working efficiency

• Extended long track undercarriage with longer ground contact length and approximately 35kPa ground pressure, ensuring excellent anti-tipping stability and passability on soft, muddy and swampy job sites

• Reinforced heavy-duty X-shaped chassis frame with improved structural design, excellent torsional rigidity and impact resistance, highly adaptable to rough quarry sites and harsh unpaved working conditions

• High-strength boom and stick fabricated with Caterpillar's automated welding process, superior fatigue resistance for continuous high-intensity digging and loading operations

• Verified accident-free history with complete maintenance files; all major components including engine, main pump, control valve and swing motor remain original factory specifications. Global spare parts are easily accessible

• Ready in stock with fast delivery: machines are fully serviced and tested, and can be shipped within 7–15 working days after deposit confirmation. Full one-stop export service is provided
