The challenge

The Mine Maintenance Team developed initiatives that increased truck availability, improving work quality and maintenance practices. With the help of these initiatives, the maintenance department was able to reduce downtime and costs related to equipment failures.

The efforts included the implementation of a first-class maintenance methodology such as SMED (Pit Stop Work Modes, Quality Inspections, and Short intervals. The initiative helped to ensure that all necessary tools, spares, and skills were available before haul trucks arrived at the shop. As a result, we were able to shorten the time each haul truck was in the shop, enabling all haul trucks to return to service sooner.

We joined efforts with other areas, such as Wenco, to monitor and calibrate payload using a calibrations system. By doing so, we reduce the impact caused by excessive payloads affecting the chassis on older units. Furthermore, we minimized tire rotation cycle times and Preventive Maintenance durations with the Pit Stop initiative, but we took this to another level by considering the cost factor. We added the Kidney-Looping process to reduce the consumption of lubricants extending the life of the lubricants’ replacement from the expected 1000 hours to 4000 hours.
