Product Description
Proven reliability meets compact versatility in this 2017 Komatsu PC56-7 mini excavator, currently located in Hefei, Anhui. Powered by the robust Komatsu S4D87E-1 engine delivering 34.5kW at 2300rpm, this 5.3-ton machine combines Japanese engineering precision with practical performance for confined jobsites. The water-cooled, 4-stroke direct injection motor ensures consistent operation across demanding applications.
Komatsu's reputation in the used equipment market stands unmatched. Parts availability remains exceptional even for older models, minimizing downtime and maintenance costs. Resale values consistently outperform competitors, protecting your investment long-term. This PC56-7 features impressive working parameters: 6,130mm maximum digging radius, 3,810mm digging depth, and bucket capacity ranging from 0.055 to 0.22m³. The fixed plunger rotary motor and dual variable plunger travel motors deliver precise control through hydraulic circuits operating at 26.5Mpa.
Compact dimensions (5,935mm length × 1,960mm width × 2,550mm height) facilitate easy transport, while the 1,650mm rear turning radius enables operation in restricted spaces. With 120L fuel capacity and comprehensive hydraulic systems, this Komatsu repr
