Technical Specifications

Detailed Description & Applications

The Used Hitachi EX350 ZX350 Excavator is a medium-sized hydraulic excavator built on the proven ZAXIS platform, combining robust structure and Isuzu AA-6HK1X diesel power for consistent on-site productivity. Designed for a wide range of earthmoving tasks, this machine balances reach, digging force and bucket capacity to serve contractors, rental fleets and specialist excavation teams.

Core Performance Characteristics

Equipped with a 184 kW engine and a maximum tear-out force of 246 kN, the unit provides reliable digging and loading performance across compact-to-medium excavation jobs. The 1.38 m³ bucket capacity and 10.89 m maximum horizontal reach allow efficient cycle times when loading trucks, trenching or shaping foundations. Track width at 600 mm and a transport width of 3.19 m make road moves and site positioning manageable without excessive disassembly.

Design Advantages and Build Quality

The ZX350’s structural design emphasizes durability—reinforced boom and arm geometry maintain stability under heavy loads and reduce metal fatigue. The Isuzu six-cylinder engine provides linear torque delivery with a peak torque at 1700 rpm, offering responsive control in digging cycles while conforming to Tier 2 emission standards. For used equipment buyers, the ZAXIS lineage ensures parts availability and known service procedures that support long-term asset management.

Operational Efficiency

• Balanced fuel consumption and power output for extended jobsite hours.

• Optimized hydraulic flow for consistent bucket fill and smooth swing control.

• Transport dimensions suitable for regional haulage with standard trailers.

Typical Applications

This excavator performs well across:

1. General construction and site preparation — foundations, trenching, and backfilling.

2. Road building and utilities — pipe installation, culvert works, and shoulder grading.

3. Quarry and aggregate handling — loading trucks and stockpile management when paired with the appropriate bucket.

4. Demolition support for selective dismantling and material handling.

Who Benefits Most

The Used Hitachi EX350 ZX350 Excavator is suited for mid-size contractors who need reliable digging capacity without the operating costs of larger classes. Rental companies benefit from its versatile sizing and parts commonality, while municipal works departments and infrastructure contractors will value the machine’s digging reach, bucket capacity and straightforward maintenance profile.

Maintenance and Ownership Considerations

Purchasing a used EX350/ZX350 requires focused inspection of hydraulic lines, swing gear condition, undercarriage wear (track links, rollers and idlers) and engine service records. Regular maintenance extends uptime and supports resale value. Recommended checks include:

• Verify service history for the Isuzu AA-6HK1X engine and confirm oil/filter change intervals.

• Inspect boom and arm pins for excessive wear and measure bushings against manufacturer tolerances.

• Assess track condition—600 mm shoes are common and replacement parts are widely available.

• Test hydraulic function under load to ensure consistent flow and absence of internal leakage.

Buying Guidance

When evaluating used inventory, request photographs of wear items, engine hours, and any recent repairs. Confirm the machine’s configuration—bucket width (1.36 m) and capacity (1.38 m³) affect cycle efficiency and application fit. Prioritize units with documented preventive maintenance to minimize early ownership costs.

Summary

In summary, the Used Hitachi EX350 ZX350 Excavator delivers a balanced package of power, reach and durability suitable for a broad set of mid-range earthmoving tasks. Its ZAXIS-based design and Isuzu engine provide a dependable platform for contractors and rental operators seeking proven performance with manageable lifecycle costs. Proper inspection and routine maintenance will ensure the machine returns strong service life in demanding environments.
