Product Description
Built for precision work in confined spaces, this 2015 Hitachi ZX70-3 delivers exceptional operator control across demanding job sites. Weighing 6,470 kg with a 0.33 m³ bucket capacity, this 7-ton excavator combines compact dimensions with serious digging power—55 kN bucket force and 4,170 mm maximum depth ensure productive cycles in utility, landscaping, and urban construction applications.
Powered by a reliable Isuzu AU-4LE2X engine (40.5 kW at 2000 rpm), the ZX70-3 features water-cooled efficiency and dual variable axial piston pumps for responsive hydraulic performance. Operators benefit from smooth 10.5 rpm rotation speed, excellent visibility over the 2,600 mm cab height, and confident maneuverability with a tight 1,720 mm front turning radius. Travel speeds of 3.4/5.3 km/h and 70% climbing ability tackle varied terrain with stability.
