Product Description
Engineered for longevity, this 2018 Komatsu PC56-7 mini excavator demonstrates the superior build quality that defines Komatsu's manufacturing standards. With a 5.3-ton working weight and powered by the reliable Komatsu S4D87E-1 engine delivering 34.5kW at 2300rpm, this proven workhorse handles demanding tasks with consistent performance. Its 0.055-0.22m³ bucket capacity and impressive 3810mm maximum digging depth make it ideal for confined urban projects and utility work.
Built to last through years of rigorous operation, this machine features water-cooled efficiency, a 2.434L displacement engine, and robust hydraulic systems operating at 26.5 MPa. The compact 5935mm transport length and 1960mm width ensure easy site mobility, while the 6130mm maximum digging radius provides exceptional reach for its class. Currently located in Anhui, this Japanese-engineered excavator represents proven reliability backed by Komatsu's joint-venture manufacturing precision from Jining, Shandong Province.
