Product Overview

The Caterpillar 320GX is a next-generation value-class 20-ton medium hydraulic crawler excavator designed for contractors who prioritize low operating costs and reliable production performance. As a cost-optimized model in Caterpillar's latest 20-ton lineup, the 320GX is equipped with an original CAT C4.4 turbocharged diesel engine and a refined load-sensing hydraulic system, delivering up to 15-20% better fuel efficiency compared to previous classic series while maintaining durable structural strength and stable digging performance.

Every pre-owned 320GX excavator in our inventory has passed a rigorous 85-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. As a late-model machine with low comprehensive operating cost and much lower acquisition cost than a brand-new unit, it is a high-ROI choice for overseas construction contractors and equipment rental fleet operators.
