Strengthened Quarry Bucket for Provides Outstanding Wear-resistance (optional)
The bucket for specific use in quarry is impact and wear resistant, providing high performance and long life.
Koma-hard materials* provide excellent wear resistance. Combined with adoption of long-life KMAX tooth, durability of bucket
is drastically enhanced.
* Koma-hard materials (KVX materials):
Komatsu developed, wear-resistant, reinforced materials.
Brinell hardness: 500 or more (180kgf/mm
Features high wear-resistance and little quality change by
the heat generated during rock loading, maintaining the
hardness for a long term.
KMAX Tooth for Quarry Bucket
• Unique bucket tooth shape superior digging
performance
• Long-term high sharpness
• Great penetration performance
• Hammerless, safe, and easy tooth
