Product Specification

Why choose this machine?

1. Power system
Engine:
Model: Original Hitachi/Isuzu turbocharged diesel engine (such as Isuzu 4JG1X).
Power: Approximately 66–69 kW (89–93 HP), in compliance with Tier 3/Stage IIIA emission standards (some new models upgraded to Tier 4).
Features: Low-speed high-torque design, good fuel economy, suitable for long-term operation.
Hydraulic system:
Load-sensing hydraulic system (CLSS), pump-valve joint control, fast response and energy saving.
Two optional working modes (economic/standard), adjust power output according to working conditions.
2. Performance parameters
Item Typical value (ZX120-5G/6)
Operating weight 12.2–12.8 tons
Bucket capacity 0.45–0.6 m³ (optional)
Maximum digging depth 6.1–6.5 meters
Maximum digging radius 8.7–9.2 meters
Travel speed 4.8–5.5 km/h
Gradability 35° (70%)
3. Structure and durability
Chassis:

Reinforced X-type frame, strong torsion resistance, suitable for rugged terrain.

Optional extended crawler (increases ground contact area and reduces ground pressure).

Working device:

The boom and bucket arm are made of high-strength steel with long service life; the hinge points are sealed and lubricated to reduce wear.

Maintenance convenience:

Centralized lubrication points, side-opening engine compartment, easy to replace filter element.

4. Cab and control
Ergonomics:

Spacious cab, suspended seat, low noise design (about 72 dB).

LCD monitoring panel, real-time display of fuel, hydraulic oil temperature and other data.

Controllability:

Pilot hydraulic joystick, light operating force (optional electromagnetic control).

Automatic idle function (reduces speed when no operation, saves fuel).

5. Technical highlights 
Intelligent functions:

e-Service: remote diagnosis, early warning of faults.

Automatic power regulation: dynamically optimize engine and hydraulic output according to load.

Environmental upgrade:

Some models are equipped with DPF (diesel particulate filter) to meet more stringent emission standards.

6. Applicable scenarios and comparison with competitors
Advantage scenarios:

Municipal pipelines, farmland transformation and other small and medium-sized earthwork operations.

Low fuel consumption, suitable for users who are sensitive to fuel costs.

Comparison of competing products:

VS Komatsu PC120: Hitachi has faster hydraulic response, Komatsu has slightly better durability.

VS Caterpillar 306: Caterpillar has a high brand premium, Hitachi has a better price-performance ratio.
