The Komatsu PC350-7 is a well-proven 35-ton heavy-duty hydraulic excavator of Komatsu 7 series from Japan, widely recognized for open pit mining, quarry and large-scale earthmoving projects worldwide. It features three core strengths: reliable genuine Komatsu SAA6D114E-3 six-cylinder engine, CLSS closed-center load-sensing hydraulic system and reinforced heavy-duty undercarriage & work equipment. It handles heavy tasks including rock stripping, quarry crushing, gravel yard loading and large infrastructure excavation. Optional hydraulic breaker piping enables quick fitting of heavy breakers, grapples and rippers for multi-purpose operation. The mechanical direct-injection Komatsu engine requires no urea aftertreatment for Tier2 versions to simplify maintenance. It maintains stable powerful output under high-temperature, high-altitude and extremely dusty mining conditions with excellent tolerance for low-grade inferior diesel. Supported by Komatsu’s global spare parts network to minimize downtime. Its thickened reinforced boom & stick and stable long track chassis deliver outstanding durability, making it the classic preferred heavy excavator for overseas quarry and mining contractors.
