Core Advantages

1. Reliable Power & Moderate Fuel ConsumptionEquipped with proven diesel engine, the D150‑7 delivers stable power output, matched with intelligent power mode selection to adapt to light‑load and heavy‑load conditions. It controls fuel consumption effectively for long‑time continuous operation. The large‑capacity fuel tank reduces refuelling frequency and improves site working continuity. Operating weight reaches 14 800 kg, providing balanced digging force for general earth‑rock working scenarios.
2. Mature Hydraulic System & Practical Working PerformanceAdopting load‑sensing hydraulic system with independent pilot control, it achieves smooth movements and easy manipulation. Flow‑pressure matching cuts wasted energy loss. Key working parameters are well‑matched for medium‑size construction requirements. Reinforced travel motor and undercarriage cope with uneven ground, muddy roads and slope conditions. Heavy‑duty track frame improves wear resistance of track shoes, rollers and idlers.
3. Ergonomic Spacious Cab & Practical Safety DesignThe operator cab features wide visibility glass windows, adjustable suspension seat and easy‑reach control levers, lowering operator fatigue for long shifts. Instrument panel provides clear real‑time machine data and fault alarm reminder. Anti‑vibration mounting reduces interior vibration. Optional rear‑view camera enhances site operation safety.
4. Solid Reinforced Structure & Low Maintenance CostBoom, arm and chassis main stress parts use thickened high‑strength steel plate. Welded key structures are strengthened for anti‑impact performance in daily earth‑moving and light rock conditions. Centralized service points for filters and oil ports simplify daily inspection and routine maintenance. Spare parts are widely available at reasonable cost, effectively reducing overall operating expenditure.
5. Flexible Attachment Compatibility for Multi‑scene UseQuick‑coupler ready for fast switching of different working tools: ‑ Standard bucket, heavy‑duty bucket (0.65‑0.85 m³) ‑ Hydraulic breaker for light rock breaking and demolition ‑ Hydraulic thumb for bulk material sorting ‑ Auger for hole‑digging and foundation work ‑ Grading bucket for slope finishing and land levelling

Multiple attachments support flexible switch among municipal works, housing foundation, demolition and land‑preparation assignments to raise machine utilization rate.
