Product Overview

The Sany SY305H Pro is a high-performance 30.5-ton class heavy-duty crawler excavator manufactured by Sany Heavy Industry, representing the upgraded flagship model in the 30-ton segment. It is globally recognized for its powerful Isuzu powertrain, industry-leading fuel efficiency, robust structural build and intelligent hydraulic control system. Equipped with Sany's proprietary DOMCS dynamic optimization control system, it delivers over 10% lower fuel consumption while maintaining high production efficiency, making it ideal for large-scale earthmoving, quarry loading, mining stripping and heavy infrastructure projects. This pre-owned SY305H Pro retains all original factory core components including the genuine Isuzu GH-6HK1 turbo diesel engine and high-displacement dual piston pump hydraulic system. Each unit passes a rigorous 180-point pre-delivery inspection, with verified no major accident history, no structural cracks on the main frame, and complete scheduled maintenance files.

As a highly cost-effective alternative to brand-name 30-ton class excavators, this used Sany SY305H Pro delivers over 90% of new-machine production efficiency at only 30%–45% of the acquisition cost. Its strong breakout force and large bucket capacity significantly improve material handling efficiency. It is the preferred workhorse for mining contractors, quarry operators, large infrastructure builders and equipment rental fleets, featuring short delivery lead time, globally accessible spare parts and extremely low long-term total cost of ownership.
