Product Description
Engineered with Komatsu's proven S4D87E-1 engine delivering 34.5kW at 2300rpm, this PC56-7 combines robust hydraulic performance with field-tested reliability. Operating at 26.5MPa across working and travel circuits, the machine features variable plunger travel motors and a fixed plunger rotation system for precise control in demanding excavation tasks. Water-cooled direct injection technology and a 2.434L displacement ensure consistent power delivery across extended operational cycles.
Compact dimensions (5935mm transport length, 1960mm width) enable access to confined job sites while maintaining a 6130mm maximum digging radius and 3810mm digging depth. Ground-specific pressure of just 30.7kPa minimizes surface disruption on sensitive terrain. Standard backhoe configuration with 0.055-0.22m³ bucket capacity handles diverse material types efficiently.
