Product Overview

The Caterpillar 345GC is a high-value 45-ton class heavy-duty hydraulic crawler excavator from Caterpillar's GC product line, purpose-engineered for medium-to-heavy construction, quarrying and mining projects with a strong focus on low operating cost and reliable production efficiency. It is globally recognized for its balanced heavy-load performance, excellent fuel economy and proven long-term durability. This pre-owned 345GC retains all original factory core components including the Cat C9.3B ACERT turbo diesel engine, main hydraulic piston pumps and heavy-duty 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 files.

As a cost-effective alternative to brand-new large-class excavators, this used Caterpillar 345GC delivers over 90% of new-machine production performance at only 28%–40% of the acquisition cost. It is the preferred heavy workhorse for mining contractors, large earthwork teams, quarry operators and heavy infrastructure construction companies, featuring short delivery lead time, globally accessible genuine and aftermarket spare parts, and extremely low long-term total cost of ownership.
