2. Key Features

2.1 High Efficiency & Low Energy Consumption

Matched with Hitachi’s optimized HIOS hydraulic system, which reduces power loss by 12% compared with the previous generation, and ensures smooth and coordinated compound movements, supporting precise control for fine operations such as precision ditching and landscape shaping.
Equipped with automatic idle and auto deceleration functions, which reduce fuel consumption by up to 10% under idle and light load conditions, effectively lowering operating costs.
The low-emission engine has high torque output at low speed, adapting to heavy load conditions such as hard soil excavation and rock breaking.

2.2 Operator Comfort & Safety

The cab is ROPS/FOPS certified, with fully sealed sound insulation design, and the internal operating noise is controlled below 72 dB(A).
Equipped with shock-absorbing adjustable seat, ergonomic pilot control joysticks with low operating force, reducing fatigue during long-time operation.
Large area panoramic front windshield and skylight, with unobstructed view of the bucket, arm and surrounding working area. Standard air conditioning system, USB charging port and storage compartments are configured to improve operating experience.

2.3 Easy Maintenance

All daily maintenance points are arranged at ground-accessible positions, and the engine hood can be opened at a large angle, which greatly reduces the time for oil replacement, filter replacement and routine inspection.
The sealed and lubricated track system, wear-resistant high-strength steel bucket and reinforced chassis structure extend the service life of wearing parts, and reduce the maintenance frequency in harsh working conditions.
Supports Hitachi Global e-Service remote monitoring system, which can realize real-time viewing of operating data, fault warning and maintenance reminder, facilitating fleet management.

2.4 High Versatility

Supports a variety of optional attachments, including hydraulic breaker, auger, wood grapple, ripper, and multi-functional bucket. The optional quick coupler can realize attachment replacement within 1 minute, adapting to different operation demands.
The short-tail design allows it to operate freely in narrow spaces such as urban streets, indoor demolition sites and residential areas. Optional rubber tracks avoid damage to asphalt and concrete pavements during municipal operations.

3. Typical Application Scenarios

Urban municipal works: pipe laying, sidewalk construction, road patching
Landscaping: terrain shaping, trench digging, tree transplanting
Agricultural construction: farmland renovation, greenhouse construction, water conservancy trenching
Small earthmoving works, indoor demolition and renovation projects
Material handling and stacking in logistics yards and farms
