Product Overview

The Caterpillar 350 is a flagship 50-ton class heavy-duty hydraulic crawler excavator manufactured by Caterpillar Inc., purpose-built for high-intensity mining, quarrying and large-scale infrastructure projects. It is globally renowned for its exceptional heavy-load durability, powerful digging performance and reliable long-term operation under harsh working conditions. This pre-owned 350 excavator retains all original factory core components including the Cat C13 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 high cost-performance alternative to brand-new large-class excavators, this used Caterpillar 350 delivers over 90% of new-machine performance at only 28%–40% of the acquisition cost. It is the preferred 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.
