Heavy-duty rock excavation involves continuous high-impact operations, placing extremely high demands on the impact resistance and wear resistance of attachments.

During pavement demolition and hard ground excavation, attachments are continuously subjected to heavy impacts and collisions, causing bucket teeth to crack or break and wear out quickly.

Construction waste mixed with reinforced concrete and other hard materials causes repeated prying and impact, making buckets prone to deformation and bucket teeth more likely to break.

Mud mixed with pebbles and sand, combined with water corrosion and abrasive wear, can cause severe wear and rusting of excavator buckets.
