Product Overview

The Caterpillar 320EL is a benchmark 20-ton class hydraulic crawler excavator from Caterpillar's E-Series lineup, globally recognized for its balanced performance, excellent fuel efficiency and outstanding durability in medium-to-heavy construction projects. This pre-owned 320EL retains all original factory core components including the Cat C6.6 ACERT diesel engine, main hydraulic piston pumps and swing drive system. Each unit passes a rigorous 150-point pre-delivery inspection, with verified no major accident history, no structural cracks on the main frame, and complete scheduled maintenance records.

As a high cost-performance alternative to brand-new 20-ton excavators, this used 320EL delivers over 90% of new-machine performance at only 30%–45% of the acquisition cost. It is the preferred workhorse for civil engineering contractors, equipment rental fleets, quarry operators and infrastructure construction companies, featuring short delivery lead time, globally accessible genuine and aftermarket spare parts, and extremely low long-term total cost of ownership.
