This highly productive copper mine was located two hours by plane from Santiago, Chile. The gear on their ball mill trunnion developed on two of the four connecting sections of the gear. ECRS/Metalock installed a combination of our Metalacing and Mini-Keylocks repair components. The repair has been serviced since then and the additions of Conventional Masterlocks were used to strengthen the repair. Microstrain V-links were mounted onto the gear, and were used to monitor the repairs during operation. These repairs will allow the mine to continue operations until the new gear is installed or further servicing is required.
