Product Description
Built in 2015, this PC56-7 mini excavator delivers proven Komatsu engineering in a compact 5.3-tonne package. Powered by the reliable Komatsu S4D87E-1 water-cooled engine producing 34.5 kW at 2300 rpm, this machine combines fuel efficiency with consistent hydraulic performance across its 26.5 MPa working circuit. Maximum digging depth reaches 3,810 mm with a 6,130 mm operating radius, while the 0.055-0.22 m³ bucket capacity handles diverse excavation tasks.
Komatsu's joint venture manufacturing ensures global parts availability and superior resale value compared to lesser-known brands. Key specifications include:
- Working weight: 5,300 kg with 320 mm ground clearance
- Transport dimensions: 5,935 × 1,960 × 2,550 mm
- Dual-speed travel: 2.6/4.1 km/h for site mobility
- 120L fuel tank and 55L hydraulic reservoir
- 1,650 mm rear swing radius for confined spaces
Currently located in Luzhou, Sichuan, this PC56-7 represents a low-risk investment backed by Komatsu's established dealer network and extensive aftermarket support throughout Asia and beyond.
