Core Performance Features

1. Advanced Hydraulic System

It is equipped with Hitachi's exclusive HIOS (Hydraulic Intelligent Optimization System), which can automatically adjust the distribution of hydraulic flow according to actual operation needs, minimize power loss, and achieve a perfect balance between operation efficiency and fuel consumption. The pilot control system provides precise and smooth operation feedback, and the compound actions (simultaneous boom lifting, arm retraction, swing, etc.) are highly coordinated, which is very suitable for fine operations such as pipe laying and terrain shaping.

2. High Reliability and Durability

The main boom, arm and bucket are made of high-tensile steel, and the high-stress welding points are specially reinforced to adapt to long-term heavy-load operations.
The undercarriage adopts sealed lubricated track links, high-manganese steel track shoes, and fully sealed carrier/support rollers, which effectively blocks the entry of mud and dust, and the service life of the walking system is more than 20% longer than similar models.
The parallel cooling system has excellent heat dissipation performance, and can operate stably for a long time in a high-temperature environment of 45℃ and above.

3. Operator Comfort and Safety

The cab complies with ROPS (Roll Over Protective Structure) and FOPS (Falling Object Protective Structure) safety standards, providing sufficient safety guarantee for operators.
It is equipped with a fully adjustable suspension seat, low-force pilot control levers, high-performance air conditioning and noise reduction design (indoor noise is controlled below 75dB), which greatly reduces the fatigue of long-term operation.
Large-area front and side windows provide a 360° wide field of view, effectively reducing operation blind spots.
The LCD monitoring panel displays real-time operating parameters and fault warning information in real time, which is convenient for operators to grasp the equipment status.

4. Easy Maintenance

All daily maintenance points are arranged at ground-accessible positions: engine oil filter, fuel filter, air filter, and hydraulic oil return filter are all concentrated on the right side of the fuselage, which can be replaced quickly without climbing the machine. The centralized lubrication system of the working device also reduces the workload of daily maintenance.

Optional Attachments

The ZX120 supports a variety of customized configurations to meet different operation needs:

Quick coupler, hydraulic breaker pipeline, dozer blade
Rubber track pads, auger, wood grapple, ripper
Special buckets for different working conditions (mud bucket, rock bucket, grid bucket, etc.)

Typical Application Scenarios

Municipal engineering: trench digging for pipeline laying, road repair, urban green belt sorting
Civil construction: foundation excavation of small and medium-sized buildings, site leveling, construction material and waste loading
Agricultural water conservancy: farmland leveling, irrigation ditch digging, small reservoir construction, rural road renovation
Small mining sites: ore handling, waste stripping, site finishing
Small demolition work: small building demolition, waste removal when equipped with a hydraulic breaker

Market Advantages

Ultra-low fuel consumption: the comprehensive fuel consumption under conventional working conditions is only 6-9L per hour, which is 10-15% lower than similar 12-ton excavators
Low failure rate: the mature Isuzu power platform and HIOS hydraulic system have an average trouble-free operation time of more than 8,000 hours
High residual value: as one of the most popular 12-ton excavators in the global second-hand market, its 3-year residual value is 15-20% higher than most competing products
Low maintenance cost: common spare parts are widely available around the world, and the price is 10-30% lower than that of European and American brand models of the same tonnage
