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.
 
* We take client con­fi­den­tial­i­ty seri­ous­ly. While we have kept the brand anony­mous, the results are real.
