Core Advantages

1. Reliable Power & Excellent Fuel‑Saving Performance

Powered by the CAT C4.4 diesel engine, rated net power 103.6 kW (139 hp)Cat. It adopts Smart working mode with synchronized engine‑electro‑hydraulic control, delivering steady power while cutting fuel consumption significantlyCat. No DEF diesel exhaust fluid is required for routine operation, reducing consumable costs and downtime. Optimized power calibration fits daily cyclic earth‑moving tasks. The large‑capacity fuel tank supports long continuous shifts, lowering refueling frequency. Operating weight reaches 20 400 kg, offering stable digging capacity for conventional earth and soft‑rock working conditionsCat.

2. Mature Electro‑Hydraulic System & Practical Working Parameters

Equipped with load‑sensing electro‑hydraulic control system, realizing precise flow‑pressure matching, smooth movement and reduced invalid energy loss. Fast cycle speed improves overall job‑site efficiency. Key working specifications:

• Maximum digging depth: 6 430 mm
• Maximum ground‑level reach: 9 250 mm
• Maximum dumping height: 6 330 mm
• Standard bucket capacity: 0.93‑1.1 m³
• Main hydraulic system pressure: 34.3 MPa

Two‑speed travel system adapts to uneven ground, muddy sites and slope operations. Reinforced heavy‑duty undercarriage resists dust and sediment, extending service life of track shoes, rollers and idlers.

3. Ergonomic Operator Cab & Practical Safety Configuration

The heavy‑duty operator cab follows human‑factor design, with push‑button engine start and 8‑inch high‑resolution touch‑screen monitor for intuitive machine status checking. Optimized control layout reduces operator fatigue during long‑hour shifts. Optional automatic air‑conditioning adapts to high‑temperature and low‑temperature environments. Built‑in vibration‑damping and noise‑reduction structures improve working comfort. Intelligent instrument panel supports fault self‑diagnosis and real‑time equipment condition monitoring. Multiple safety protection structures meet international construction‑site safety requirements.

4. Reinforced Structure & Low‑Cost Maintenance

Boom, arm and chassis key stress parts adopt high‑strength steel with structural reinforcement, resisting impact and torsion for general tough construction sites. Upgraded hydraulic pipe‑joint sealing minimizes oil leakage and impurity ingress. Centralized ground‑level service points for filters, oil ports and inspection ports make daily inspection and maintenance fast and labor‑savingCat. Using proven classic components, the machine features low failure rate and high attendance rate, effectively cutting long‑term ownership and maintenance expenses for project owners.

5. Rich Attachment Compatibility & Flexible Multi‑Scenario Use

Supports quick‑coupler rapid tool switching, compatible with multiple working attachments to expand application scope:

• Standard earth‑moving buckets, heavy‑duty wear‑resistant buckets
• Hydraulic breakers for light demolition and rock breaking
• Hydraulic thumbs for sorting and handling bulk materials
• Auger drills for foundation hole‑digging
• Rippers & grading buckets for land leveling and trench finishing

Versatile attachments enable free switching between earth‑moving, demolition, foundation construction and fine finishing work, maximizing machine utilization rate.

Typical Application Scenarios

1. Municipal & Urban ConstructionUrban site development, foundation excavation, pipeline trenching, road reconstruction and residential building construction. Performs well in compact urban job‑sites with flexible movement and stable output.
2. Highway & Transportation InfrastructureRoadbed excavation, embankment backfilling, slope trimming and site preparation for highway and secondary‑road projects, meeting large‑volume conventional earth‑moving demands.
3. Water Conservancy ProjectsRiver dredging, pond excavation, dike reinforcement and flood‑prevention works. Adapts to wet and muddy terrain for water‑related earth‑moving assignments.
4. Quarry & Auxiliary Material HandlingLight‑duty quarry loading, stockyard stacking‑and‑sorting, waste‑soil cleaning and material transfer.
5. Land Development & Rental‑Fleet OperationFarmland reclamation, industrial‑zone site leveling and rental‑service scenarios. Low operating cost and fast return‑on‑investment make it highly popular for equipment rental companies.
