Product Description
Built for precision work in confined spaces, this 2019 Komatsu PC56-7 mini excavator delivers 34.5kW of reliable power through its Komatsu S4D87E-1 water-cooled engine. With a 5.3-ton operating weight and bucket capacity ranging from 0.055 to 0.22 m³, this machine handles trenching, foundation work, and utility installation with exceptional control. Maximum digging depth reaches 3,810mm while maintaining a compact 1,650mm rear turning radius—ideal for urban job sites and restricted access areas.
- Komatsu S4D87E-1 engine: 34.5kW at 2300 rpm for consistent performance
- Maximum digging reach: 6,130mm with 5,860mm excavation height
- Hydraulic system: 26.5 Mpa working circuit with fixed plunger rotation motor
- Transport dimensions: 5,935mm L × 1,960mm W × 2,550mm H
- Fuel capacity: 120L tank for extended operation
- 400mm track plates with 1,980mm ground contact length
