Product Description
Engineered with precision hydraulics and proven ISUZU power, this 2013 Kobelco SK75 delivers consistent performance across demanding jobsites. At its core sits the ISUZU AU4LE2X engine—a water-cooled, 4-cylinder powerplant generating 41 kW at 2200 rpm through 2.179L displacement. Hydraulic architecture features a double variable displacement axial piston pump working at 29.4 Mpa, supported by dedicated circuits: 27.5 Mpa for travel, 14.5 Mpa for rotation, ensuring responsive control under load.
Built to joint venture/import standards in Chengdu, this 7-ton excavator combines compact dimensions with impressive reach capabilities. Maximum digging radius extends to 6,460 mm while maintaining a tight 1,760 mm front turning radius—critical for confined spaces. Vertical digging depth reaches 3,450 mm, backed by a maximum excavation height of 7,390 mm. Dual travel speeds (2.8/5.3 km/h) optimize productivity between positioning and transport modes.
