2. Core Advantages & Features

2.1 High Efficiency & Low Fuel Consumption

Equipped with Hitachi's proprietary HIOS III (Hydraulic Intelligent Operating System), which achieves highly precise matching between engine output and hydraulic system demand, with 10-15% lower fuel consumption compared to同类 products of the same level.
Two operation modes (Power mode / Economy mode) are available for switching: Power mode provides strong power for heavy load conditions such as hard soil excavation and breaking; Economy mode reduces fuel consumption for light load conditions such as site leveling and material handling.
Built-in auto-idle function: automatically reduces engine speed when the machine is stationary for more than 5 seconds, further lowering fuel loss and noise.

2.2 Superb Reliability & Durability

The boom, arm and chassis frame are made of high-strength wear-resistant steel, with reinforced welding at stress concentration points, which can adapt to harsh working conditions such as rocky sites and long-term heavy load operation.
The core hydraulic components and engine parts adopt multi-layer sealing design, which effectively prevents dust and water from entering, and extends the service life of core parts.
Extended maintenance interval: engine oil replacement every 500 working hours, hydraulic oil replacement every 4,000 working hours, greatly reducing downtime and operation cost.

2.3 Operator Comfort

The cab is ROPS/FOPS certified, with excellent anti-roll and falling object protection performance, ensuring the safety of operators.
The fully adjustable suspension seat, low-effort pilot control joystick and spacious interior space reduce operator fatigue during long hours of operation.
The noise level inside the cab is controlled below 72 dB(A), with high-efficiency air conditioning system, multi-position air outlets, storage compartments and radio configuration, providing a comfortable operating environment.
Ultra-wide front and side glass design minimizes the blind area, so that the operator can clearly observe the working surface and surrounding conditions.

2.4 Easy Maintenance

All daily maintenance points (air filter, oil filter, fuel filter, hydraulic oil dipstick, etc.) are arranged at positions accessible from the ground, no need to climb the upper car for inspection.
Centralized grease lubrication points are designed, which greatly improves the efficiency of regular lubrication maintenance.
Equipped with an intelligent fault self-diagnosis system, which displays fault codes directly on the instrument panel, helping maintenance personnel locate problems quickly.

2.5 Strong Versatility

Supports matching with a variety of auxiliary attachments, including hydraulic breakers, wood grabs, augers, rippers, slope trimming buckets, etc. Optional quick coupler can realize attachment replacement within 3 minutes, adapting to different operation needs.
Compact body design allows it to work in narrow spaces such as indoor demolition sites, urban residential areas, and farm orchards.

3. Typical Application Scenarios

Urban municipal construction: trench excavation for water, electricity and gas pipelines, road repair, sidewalk renovation
Landscaping and agricultural engineering: tree pit excavation, irrigation canal construction, site leveling, greenhouse construction
Small earthwork projects: foundation pit excavation for residential buildings, muck transfer, site clearing
Indoor demolition and renovation: interior dismantling of old buildings, waste removal
Auxiliary operation of mines and quarries: slope cleaning, ore transfer, site sorting
Material handling: loading and unloading of sand, gravel, timber, agricultural products and other bulk materials

The ZX70, as a benchmark product in the 7-ton small excavator market, has a very high residual value in the second-hand equipment market, and is one of the most cost-effective choices for small and medium-sized engineering projects.
