Komatsu PC650/PC850 in Large‑Scale Quarry Operations

March 18, 2026

Industry: Limestone & basalt quarry

Equipment: Komatsu PC650 / PC850 large mining excavators

Challenge:

Large quarries demand extreme strength and wear resistance. Previous teeth broke under heavy loads, and uneven wear reduced bucket efficiency.

Solution:

Heavy‑duty quarry‑grade Komatsu bucket teeth with increased material thickness, reinforced shank, and wear‑resistant surface treatment.

Results:

Service life increased by over 50% vs. standard teeth
No catastrophic breakage during 24/7 loading operations
Improved bucket fill rate by ≈ 10%
Lower total cost per hour (parts + labor + downtime)

Client Testimonial:

“Our PC850 works in harsh rock conditions. These teeth deliver stable performance and strong protection. We trust them for long‑term use.”
