1. Core Performance Parameters: Power and Efficiency at Their Peak
As the "heart" of engineering construction, the HWL90 wheel excavator is equipped with a YC4FA6-T300 engine, delivering a rated power of 48kW/2200rpm for stable and robust performance, even in complex working conditions like clay and gravel. Paired with a high-efficiency hydraulic system boasting a hydraulic pump displacement of 110L/min, it achieves a bucket digging force of 21kN·m and a stick digging force of 24kN·m, easily handling heavy-duty tasks like hard soil excavation and rock crushing—boosting efficiency by 15% compared to similar models!
✅ Key Performance Metrics:
Operating weight: 7.2 tons (lightweight design for superior fuel economy)
Travel speed: 30km/h (fast highway maneuverability for reduced transit time)
Swing speed: 10r/min (precise control for micro-operation tasks)
Working pressure: 24MPa (high-pressure system for enhanced load capacity)
2. All-Around Working Range: From Precision Tasks to Heavy-Duty Excavation
The versatility of the HWL90 wheel excavator stems from its scientifically optimized working range parameters:
Maximum digging height: 6930mm – ideal for elevated material handling, such as factory construction and bridge inspections;
Maximum digging depth: 3655mm – perfect for deep foundation excavation and pipeline laying;
Maximum dumping height: 5170mm – efficient for material stacking and debris removal;
Rear swing radius: just 1980mm – allows in-place turning in narrow spaces, perfect for urban village renovation and indoor demolition.
With a digging flow rate of 3.655m³/min, the bucket achieves industry-leading throughput per minute. Combined with a ground contact pressure of 0.28㎡, it remains stable on soft ground without sinking—ideal for challenging terrains.
3. Compact Design for All Scenarios: The "Golden Dimensions" of a 7.2-ton Machine
For small-to-medium engineering projects, "site maneuverability" and "venue adaptability" are critical. The HWL90 wheel excavator features a space-efficient design with a compact body measuring 6410mm (L) × 2020mm (W) × 2840mm (H), easily navigating urban main roads, underground garages, or narrow alleyways—no more site access restrictions.
✅ Lightweight Design Highlights:
Tire model: 24.00-16 (wear-resistant and impact-resistant, suitable for diverse road conditions);
Fuel tank capacity: 130L for long reducing mid-task refueling downtime;
Structural components use high-strength steel with wear-resistant coatings, extending service life by 30%.
4. Detail-Oriented Design: Reducing Operational Costs
Beyond raw power, the HWL90 wheel excavator caters to engineers’ "cost-saving pain points" with user-centric features:
Easy maintenance: Concentrated layout of engine and hydraulic systems for hassle-free daily upkeep;
Comfortable operation: Spacious cab with wide visibility and a suspended seat for reduced fatigue during long shifts;
Safety assurance: Built-in overload protection devices prevent accidents from misoperation, safeguarding construction safety.
