Product Description

Built for precision work in confined spaces, this 2018 Hitachi ZX70-3 delivers exceptional operator control across demanding job sites. Weighing 6,470 kg with a 7-ton operating class, this compact excavator combines Japanese engineering with practical functionality. The Isuzu AU-4LE2X engine produces 40.5 kW at 2,000 rpm, providing reliable power through a water-cooled, 4-cylinder configuration with 2.2L displacement.

Operator-focused design ensures confident handling throughout extended shifts. Variable axial piston motors drive smooth travel at dual speeds of 3.4/5.3 km/h, while the 10.5 rpm rotation speed enables precise positioning around obstacles. Ground-level stability comes from 30 kPa ground pressure distributed across 450 mm track plates, supporting a 70% climbing ability on slopes. Hydraulic responsiveness is managed through dual variable axial piston pumps delivering combined flow rates up to 228.8 l/min at 26 MPa working pressure.

Key Performance Specifications:
