In mining operations, the selection of large mining crawler excavators must precisely align with scenario characteristics. Underground mines, constrained by limited space and high gas risks, require compact models with explosion-proof designs (certified by IECEx) and a small turning radius (≤3 meters). In contrast, open-pit mines prioritize production efficiency, emphasizing large bucket capacity (≥2.4m³), high weather resistance (dust/corrosion-resistant coatings), and heavy-load stability.
Hengwang Group offers differentiated solutions for both scenarios:
· Underground Mines: The HW-520 mining-dedicated large mining crawler excavator is equipped with a Cummins QMS11 engine, a three-stage fuel filtration system, and double-tooth tracks. Its explosion-proof design meets international certifications, enabling efficient operation in narrow roadways.
· Open-pit Mines: The HW-1300 giant mining excavator, a large mining crawler excavator, features a 567kW Cummins QSK23 engine, a standard 8m³ bucket, high-strength double-tooth tracks, and an integral casting structure. Capable of extracting 12,000 tons daily, it is ideal for large open-pit mines.
Case Study: After replacing outdated equipment with the HW-1300 large mining crawler excavator at a South American open-pit iron mine, the single-bucket load increased by 40%. Combined with an intelligent remote control system, overall efficiency improved by 30%, and the maintenance cycle extended by 50%.
