About · Hitachi ZX170Overview
The Hitachi ZX170 is a conventional tail-swing crawler excavator in the 17-tonne class, positioned in the mid-range segment of hydraulic excavators. It operates at a working weight of 17,700 kg and is powered by an engine producing 163 hp, giving it a robust power-to-weight ratio for its class. Standard bucket capacity is rated at 0.8 m³, consistent with general-purpose earthmoving work at this size tier.
Typical applicationsWhere this machine is used
Machines in the 17-tonne excavator class are well suited to site preparation, foundation excavation, utility trenching, and road construction projects where a balance of digging force and transport mobility is required. The ZX170 is a practical choice for contractor fleets working on mid-scale civil and infrastructure projects, as well as quarry stripping and bulk material handling where a 0.8 m³ bucket offers productive cycle times without requiring heavy-haulage transport logistics.
Used-market inspectionWhat to check before buying
Before purchasing a used ZX170 or comparable 17-tonne excavator, inspect the undercarriage closely: track pad thickness, roller condition, and sprocket wear are reliable indicators of remaining service life and are among the most significant refurbishment cost drivers in this class. Review the hydraulic system for leaks at the main control valve, cylinders, and hose connections, and confirm that auxiliary lines are present and functional if attachment versatility is required. Check the swing ring and gear for play and unusual noise, as these components are costly to address on machines of this weight class. Request service records to verify oil change intervals and filter replacement history, and confirm that the engine shows no visible smoke under load. Cab condition, climate control function, and monitor display integrity are worth assessing, particularly if the machine will be operated in demanding environments over extended shifts.
Current marketPrice position
The Hitachi ZX170 competes directly with the Caterpillar 316 and the Volvo EC160, all three occupying the 16-to-18-tonne crawler excavator segment. Against the Caterpillar 316, the ZX170 offers a higher stated operating weight and greater engine output, which can translate to deeper digging capability and lifting capacity on demanding ground conditions. Compared with the Volvo EC160, the ZX170 sits above it in operating weight while sharing a broadly similar bucket capacity, making specification comparisons relevant when evaluating fleet compatibility and parts support preferences. Within this class, the primary factors that move a unit within its price band are accumulated service hours, maintenance history documentation, the presence of a quick-coupler or hydraulic thumb, auxiliary hydraulic lines for attachment versatility, undercarriage wear condition, and overall machine configuration including blade fitment and cab specification.
